This study describes the use of a 15 000 gene microarray developed for the toxicological model
species, Pimephales promelas, in investigating the impact of acute and chronic methylmercury
exposures in male gonad and liver tissues. The results show significant differences in the
individual genes that were differentially expressed in response to each treatment. In liver, a total
of 650 genes exhibited significantly (P < 0�05) altered expression with greater than two-fold
differences from the controls in response to acute exposure and a total of 267 genes were
differentially expressed in response to chro*nic exposure. A majority of these genes were
downregulated rather than upregulated. Fewer genes were altered in gonad than in liver at both
timepoints. A total of 212 genes were differentially expressed in response to acute exposure and
155 genes were altered in response to chronic exposure. Despite the differences in individual
genes expressed across treatments, the functional categories that altered genes were associated
with showed some similarities. Of interest in light of other studies involving the effects of
methylmercury on fish, several genes associated with apoptosis were upregulated in response to
both acute and chronic exposures. Induction of apoptosis has been associated with effects on
reproduction seen in the previous studies. This study demonstrates the utility of microarray
analysis for investigations of the physiological effects of toxicants as well as the time-course of
effects that may take place. In addition, it is the first publication to demonstrate the use of this
new 15 000 gene microarray for fish biology and toxicology. # 2008 The Authors

organisms (Klaper & Thomas, 2004; Thomas & Klaper, 2004). By measuringexpression of thousands of genes at once, genomics provides a simultaneous mea-surement of the changes that are occurring in multiple biochemical pathways ina tissue. These techniques complement traditional environmental risk assessments.Standard studies of the consequences of exposure to a stressor often measure grossresponses in the form of mortality, changes in growth or reproductive declines anddo not aid in defining a mechanism of action. Genomic techniques aid in the eval-uation of an organismal response by providing a more detailed analysis of ef-fects and modes of action as well as a means to generalize across stressors andspecies (Klaper & Thomas, 2004; Snape et al., 2004).Methylmercury is a common environmental contaminant formed when in-
organic mercury is methylated by environmental bacteria. It is known to be aneurotoxin, and in developing mammals, it has been found to cause significantneurological problems (Zelikoff et al., 1995; National Research Council, 2000).However, the effects of methylmercury on other physiological processes, suchas reproduction, are relatively unknown.Studies of the impact of methylmercury contamination in fish in particular have
found declines in reproductive hormones, smaller gonad development or atro-phy, delays in spawning and effects on fecundity (Wester, 1991; Kirubagaran &Joy, 1992; Friedmann et al., 1996; Hammerschmidt et al., 2002; Drevnick &Sandheinrich, 2003). The mechanisms that cause these effects are unclear; how-ever, in the previous study using a 200 gene macroarray (Klaper et al., 2006),the authors found that methylmercury exposure in fathead minnows Pime-phales promelas Rafinesque induced changes in the expression of genes com-monly associated with endocrine disruption, most specifically, alterations inthe regulation of vitellogenin mRNA in female fish. The pattern of expressionof these genes as well as others indicated a difference in the mechanism ofaction between methylmercury and other endocrine disrupting compounds.Apoptosis has been suggested in the study of Klaper et al. as well as in other
studies as an alternative mechanism that may mediate these effects. In anotherpaper, Gonzalez et al. (2005) examined the effect of dietary methylmercury onthe expression of 13 genes in muscle, liver and brain tissues of zebrafish Daniorerio (Hamilton). They found an increase in the expression of genes associatedwith production of reactive oxygen species [cytochrome c oxidase subunit I,cytoplasmic superoxide dismutase (coxl, sod)] that are also associated with apo-ptosis. These specific genes were not differentially expressed in the fatheadstudy. However, genes associated with apoptosis were altered in the study byKlaper et al.. The differences in the genes identified by Gonzalez et al. andKlaper et al. may be partly attributed to the dose provided to the fishes becauseGonzalez et al. provided a much larger dose, higher than the levels documentedin wild populations of fishes. Species differences and duration of exposure mayalso contribute to the differences between these studies. Other studies havedocumented apoptosis in reproductive tissues with methylmercury exposurein fish and rats at environmentally relevant levels (Homma-Takeda et al.,2001; Drevnick et al., 2006). The liver is critically linked to reproductive hor-mones (testosterone and oestrogen metabolism as well as vitellogenin production)in fish species, and therefore, liver apoptosis may be related to reproductivedysfunction. Apoptosis is a recognized part of follicular development and

reproductive function in the gonad; however, abnormal increases in apoptoticevents may have a significant effect on fecundity or could reduce the ability ofa tissue to respond to hormone signals.Since the time of the previous fathead minnow study, a new microarray has
been developed for the fathead minnow that incorporates sequences from over250 000 expressed sequence tags (ESTs) sequenced by the Department ofEnergy Joint Genome Institute (JGI) in co-operation with the EnvironmentalProtection Agency (EPA: Larkin et al., 2007). The study presented here com-pares the changes in gene expression in liver and gonad of male fathead min-nows after methylmercury exposure that mimics exposures documented tocommonly occur in wild fish populations (Hammerschmidt et al., 2002). Thisstudy also compares these changes over two time frames, a 4 day acute expo-sure and a chronic 600 day methylmercury exposure. It expands on the previ-ous microarray study (Klaper et al., 2006) by using this larger microarray (15000 genes v. 200 genes) from EcoArray (Gainesville, FL, U.S.A.). The goal ofthis research was to examine the short-term and long-term changes in geneexpression that occur after toxicant exposure and to identify the physiologicalmechanisms that may cause the changes in reproduction and endocrine func-tion seen in other experiments.
MATERIALS AND METHODS
MICROARRAYS
The 15 k feature microarray used for this study is the third generation of high-density oligonucleotide microarrays developed by EcoArray (Alachua, FL, U.S.A.) forbroad use in ecotoxicogenomics research with the fathead minnow, a species with a longhistory of use in aquatic toxicology research (Ankley et al., 2006). Prior to the develop-ment of the oligonucleotide arrays, very few fathead minnow cDNA sequences or ESTswere publicly available or available in an array format. To obtain more gene sequences,EcoArray developed a variety of fathead minnow cDNA and suppression subtractivehybridization libraries from multiple tissues, including gonad, liver, brain, heart andspleen from both male and female fathead minnows (Larkin et al., 2007). Concurrentwith EcoArray’s intensive sequencing effort, the JGI sequenced 250 000 cDNA clonesfrom fathead minnows and made the ESTs publicly available in August 2005 [NationalCenter for Biotechnology Information (NCBI) nucleotide database]. Clustering of thesecombined EST sequences and addition of more recent cDNA sequences submitted toGenBank (NCBI) yielded over 15 k unique fathead minnow genes, which were used todevelop a second generation 15 k gene oligonucleotide microarray.
Probes for each gene were designed using Agilent software (Agilent Technologies,Palo Alto, CA, U.S.A.) and 60-mer oligonucleotides were synthesized in situ on treatedglass slides using inkjet deposition technology (Larkin et al., 2007). Each unique probewas annotated with the gene name derived from the highest confidence match of the six-frame translation against the non-redundant (nr) protein database (NCBI). If the nr searchfailed to yield a match with e-value < 0�001, then the gene name was based on a searchof the nucleotide (nt) database (NCBI). Annotation also included biological process,cellular component and molecular function gene ontology (GO) terms (where avail-able), the top basic local alignment search tool (BLAST) hit from the nr database alongwith accession number and e-value; and the top BLAST hit from the nt database alongwith its accession number and e-value. In cases in which the direction of a gene couldnot be determined, probes were synthesized from both the strands (forward and reversecomplement) (Larkin et al., 2007). Control spots for internal quality assurance–quality

control (QA–QC) metrics were also added (proprietary Agilent control spots standardon Agilent arrays).
Because of advances in inkjet printing, high-density microarrays are now beingprinted at a greatly reduced cost. The fathead minnow microarray is now in its thirdgeneration and has been available for academic and commercial use since March2007 in two formats. The 4 � 44 k format (4 microarrays per glass slide) containsthe same 22 k 60-mer oligonucleotides discussed above, but they are printed in dupli-cate, increasing the reliability of analysis. This microarray is almost fully annotatedwith over 80% of the genes matched to named genes found in publicly available data-bases (www.ecoarray.com). The unnamed oligonucleotides make it possible to discover‘new’ genes. The second format (8 � 15 k) contains eight arrays per slide and has over15 200 genes. These genes are a sub-set of the 22 k genes and are 100% annotated. All‘no hit’ genes and any duplicates (by accession number) were removed, leaving only thebest named genes on this microarray. This array was used for this experiment and iscurrently being used to test 14 different chemical compounds for other experiments(B. Carter, pers. comm.). The probe sequences for each of the genes are available(under licence agreement) from EcoArray. GO information, when available, is providedfor both array formats. Array annotation is updated regularly.
FATHEAD MINNOW ACUTE EXPOSURES
Standard conditions were used to conduct 96 h exposures of fathead minnows. Male(2�3 � 0�6 g fish�1) adult fish were exposed. Water quality was monitored daily for oxy-gen (7�1 mg l�1, range 6�7–7�7 mg l�1), pH (mean 8�3, range 8�3–8�7), hardness (mean284 mg CaCO3 l�1, range 280–288 mg CaCO3 l�1), alkalinity (mean 243 mg l�1, range240–256 mg l�1) and total ammonia (mean 0�06 mg l�1, range 0�04–0�10 mg l�1). Waterturnover in the tanks was at a rate of 2�5 times day�1 and temperature was 21�4 � 0�4°C. In order to control the internal concentration, methylmercury (Sigma-Aldrich,St Louis, MO, U.S.A.; catalogue number 442534-5G-A) was delivered in a single intraper-itoneal injection (in a 0�02 M Na2CO3 solution). Treated fish were given an injection ofa sublethal concentration of methylmercury, 2�0 mg g�1 body mass, and controls weregiven a vehicle injection without methylmercury. The experiment consisted of 12 repli-cate male fish injected for each treatment group. Fish were housed six per tank, segre-gated by treatment. There was no mortality during treatment. At the end of thetreatment period, fish were euthanized with an overdose of MS-222 and livers and go-nads were removed and quick frozen in liquid nitrogen.
FATHEAD MINNOW CHRONIC EXPOSURES
Fathead larvae were raised until they were large enough to feed on diet (90 dayspost-hatch) and 200 minnows (mixed male and female) were transferred to each of fif-teen 180 l flow-through aquaria for exposure studies. Aquaria were filled with wellwater, temperature was maintained at 23�6 � 0�1° C and each received a 16 h light:8 hdark photoperiod cycle. Fathead minnows were maintained in aquaria receiving wellwater with a 16 h light:8 h dark cycle. Water quality characteristics were measureddaily (dissolved oxygen 6�70 � 0�01 mg l�1) or weekly (alkalinity 300 � 2 mg l�1 asCaCO3, pH 8�06 � 0�01, hardness 348 � 3 mg l�1 as CaCO3, ammonia 0�2 � 0�0mg l�1 as NH3-N). Deposited and suspended wastes were siphoned daily from eachaquarium, and residue on aquaria was removed weekly by scraping. Minnows werefed either control levels of methylmercury (0�058 � 0�004 mg g�1) or a higher methyl-mercury treatment (3�93 � 0�08 mg g�1) by dry mass. This higher concentration was de-signed to be representative of the diets of insectivorous and piscivorous fish from somemidcontinental low alkalinity lakes contaminated with Hg from non-point sources(Hammerschmidt et al., 2002). Diets were prepared by mixing food with methylmercu-ric chloride in alcohol. Control diets were mixed with alcohol alone. Alcohol was evap-orated from the food and the diet was frozen until use. Fish were fed 5% of their body

mass of their respective food treatment for 600 days, corresponding to the end of a com-plementary behaviour experiment. There was no difference in mortality or growth of fishin control v. treated tanks. After 600 days, the fish were euthanized. The liver and gonadwere harvested, placed in Trizol reagent (Invitrogen, Carlsbad, CA, U.S.A.) and kept at�80° C until extraction. RNA was extracted according to Trizol protocol.
MICROARRAY GENE EXPRESSION
For this experiment, male fathead minnows were chosen for comparison amongtreatments. Microarray hybridizations were conducted at EcoArray Inc. Total RNAfor the short-term (96 h) samples was processed using RNEasy Plus spin columns(Qiagen Inc., Valencia, CA, U.S.A.), which includes a DNase treatment step. Forthe 300 day exposures, total RNA was extracted from each of the tissue homogenates(liver and gonad), DNase-treated (DNA free) RNA was extracted for five or moresamples of each tissue, and the integrity of all RNA samples was examined using aBioAnalyzer 2100 (Agilent Technologies Inc., Santa Clara, CA, U.S.A.). Four sam-ples were selected with 260–280 and 260–230 ratios closest to 2�0. We used a one-colour design for this project, following the protocol established by Agilent Technol-ogies (version 5.5 of February 2007). For each experimental sample, the cyanine-3(cy-3) fluorescent label was incorporated directly into the cRNA during the in vitrotranscription labelling reaction using Agilent’s Low RNA Input Linear Amplificationkit. This method uses T7 RNA polymerase, which simultaneously amplifies the targetmaterial and incorporates the cy-3 label. For each protocol, 7 ml of Agilent controlspikes were added to each 900 ng sample (Agilent’s RNA Spike-In Kit, One Color)to hybridize to control spots on the arrays for quality control and dynamic range.The resultant cRNA was purified using a modified protocol for Qiagen’s RNeasymini-spin columns and then analysed for dye incorporation rates and quantity ona NanoDrop ND-1000 spectrophotometer. Equal quantities (600 ng) of the cy-3labelled samples were fragmented prior to hybridization, mixed with 2� GE Hybrid-ization Buffer HI-RPM (GE Healthcare, Chalfont St Giles, U.K.) and then applied tothe microarray. Slides were hybridized in a stainless steel hybridization chamber that‘sandwiches’ the hybridization buffer and samples between the microarray slide anda gasket slide, creating a leak-proof chamber. They were hybridized at 65° C for 17h in a rotor oven. Images were acquired from the hybridized gene chips using an Agi-lent scanner. Four biological replicates were run for each tissue (liver and gonad) forcontrols and treated fish and for each time period for a total of 32 microarrays.
DATA ANALYSIS
Data from the arrays were extracted using Feature Extraction 9.0 (Agilent Techno-logies). The .txt files were imported into GeneSpring (GS: Agilent Technologies) andpreprocessed using the ‘Enhanced Agilent FE Import’ macro. GeneSpring convertedthe Feature Extraction software flags (e.g. population and non-uniformity outliers) intothe GS flags (present, marginal, absent or unknown) and compared signal intensity withthe localized background. All genes were normalized according to the GS preset pro-tocol for one-colour microarrays (data measurements <0�01 to 0�01; per chip normal-izes to 50th percentile; per spot: normalizes to median). Genes were filtered on flagsand only those genes that were marked ‘present’ in at least four of the 32 arrays wereincluded in subsequent analyses (n ¼ 12 671). This removes all features that are veryclose to background or mislabelled and leads to more reliable statistical results. One-way ANOVA was selected to compare treatments with their respective controls.
Statistical analysis of GO (Ashburner et al., 2000) terms was conducted with the fastassignment and transference of information (FatiGO) web tool (Al-Shahrour et al.,2005, 2006). This tool uses Fisher’s exact test to detect differences in frequency ofGO terms associated with two lists of genes. P-values were not adjusted for multiplecomparisons because the available methods for multiple comparison testing are too

conservative for the purpose, the discovery of gene classes associated with response tomethylmercury exposure. FatiGO analysis was used to determine the differentialdistributions of Biological Process GO terms between genes that were altered andunaltered in response to each treatment to determine which categories were statisticallyoverrepresented v. their presence on the array.
QUANTITATIVE POLYMERASE CHAIN REACTION OFRELEVANT GENES
Individual genes were chosen for quantitative polymerase chain reaction (qPCR)based on available primers and significance to the results from the array experiment. Eachprimer set was validated for specificity and efficiency by running dissociation and stan-dard curves, respectively. A melting (dissociation) curve was generated to check for pres-ence of non-specific PCR products (data not shown). Standard curves included data froma minimum of five serially diluted cDNA samples (50, 5, 0�5, 0�05 and 0�005 ng).
For each sample, 1 mg of DNase-treated (DNA-free; Ambion Inc., Austin, TX, U.S.A.)total RNA from mercury exposed and control tissue was reverse transcribed to single-strand cDNA according to the manufacturer’s instructions using the High-CapacitycDNA Archive Kit (Applied Biosystems, Foster City, CA, U.S.A.). This kit contains ran-dom primers and Multiscribe reverse transcriptase (RT). An Eppendorf MasterCyclerGradient Thermocycler (Eppendorf, Hamburg, Germany) was programmed with a singlecycle as follows: 25° C for 10 min, 37° C for 120 min (2 h) and 4° C to end the cycle andhold. cDNA was stored at �20° C if not used immediately.
Real-time PCR was performed in 25 ml reactions that contained 100 ng cDNA for allprimers, 12�5 ml SYBR Green Master Mix (Applied Biosystems, P/N 4309155) whichincluded SYBR Green, buffer, Taq polymerase, deoxynucleotide triphosphates (dNTP)and 50 nM each of the forward and reverse primers. For all the samples, minus RTcontrols were also run to ensure the removal of all contaminating DNA. An AppliedBiosystems 7500 thermocycler was used for the PCR reactions with the following cyclevariables: 1 cycle of 50° C for 2 min, 1 cycle of 95° C for 10 min and 40 cycles of 95° Cfor 15 s and 60° C for 60 s.
Each sample was run in triplicate and the averaged value was normalized to measuredL8 rRNA values for each sample. To evaluate the results, a DDCt method of analysis wasused to compare changes in gene expression between controls and treated samples.
Primers were chosen to amplify c. 150 bp of each target gene and designed to haveapproximately similar melting temperatures (52–58° C) and a guanine and cytosine con-tent of 40–60% with minimal repeats (Table I). All primers were synthesized andhigh pressure liquid chromatography (HPLC) purified (MWG Biotech Inc., High Point,NC, U.S.A.).
RESULTS
In liver, a total of 650 genes exhibited significantly altered expression withgreater than two-fold differences from the controls (ANOVA, P < 0�05) in

response to acute exposure. Of these, 245 genes were upregulated and 405 geneswere downregulated [Fig. 1(a)]. A total of 267 genes were differentially ex-pressed (greater than two-fold change up or down, ANOVA, P < 0�05) inresponse to chronic exposure in liver. Of these, 98 were upregulated and 169genes were downregulated [Fig. 1(a)]. In gonad, fewer genes were altered thanin liver. A total of 212 genes were altered more than two-fold from the controlin response to acute exposure. Of these, 75 gonad genes were upregulated and137 genes were downregulated [Fig. 1(b)]. In response to chronic exposure, 155gonad genes were differentially expressed with a majority being downregulated

GENE EXPRESSION CHANGES IN LIVER
In liver, many genes involved in protein synthesis were downregulated inresponse to acute methylmercury exposure. In particular, GO categories of bio-synthesis, tRNA processing, ribosome biogenesis, protein folding and proteintransport were significantly overrepresented among altered genes (AppendixII). We selected categories and individual genes for further attention basedon significantly overrepresented GO categories and on previous findings thatmethylmercury exposure may have effects on oxidative stress, immune func-tion, reproduction and apoptosis [Fig. 2(a) and Table II]. Most of the genesin these categories were downregulated [Fig. 2(a)]. In contrast, exogenous anti-gen presentation genes tended to be upregulated in methylmercury-exposedfish. Of the three exogenous antigen presentation genes on the microarray,two were significantly upregulated [Fig. 2(a)].In response to chronic exposure, significantly overrepresented categories
included protein targeting, induction of apoptosis, regulation of transcription,protein processing and immune response to viruses (Appendix II). Apoptosis

and protein folding-related genes appear to be largely upregulated and immuneresponse genes were downregulated with exposure [Fig. 2(b) and Table III).
GENE EXPRESSION CHANGES IN GONAD
The GO categories significantly over represented in genes altered in thegonad in response to acute exposure are diverse and include several metabolismcategories (Appendix II). Antigen presentation was over represented, and thetwo major histocompatibility complex (MHC) genes altered in this categorywere both very strongly regulated in opposite directions [Fig. 3(a) and TableIV]. Notably, the steroid biosynthesis GO category was significantly over rep-resented among altered genes, and steroidogenic acute regulatory factor, whichis rate limiting in steroid synthesis (Stocco et al., 2005), was strongly down-regulated in testis of exposed fish (Table IV).Among genes altered in the gonad in response to chronic exposure, GO cat-
egories involved in development, the immune system and cell adhesion were sig-nificantly overrepresented (Appendix II). In the gonad, most genes within thesecategories were significantly downregulated with exposure [Fig. 3(b) and Table V].
COMPARISONS BETWEEN TREATMENTS
Overall, there appear to be a greater number of genes differentially expressedin response to the short-term exposures v. chronic methylmercury exposures.Both treatments had a larger number of downregulated genes than upregulated(Fig. 1). When genes were grouped by GO classification, there appeared to besimilarities across treatments in liver in particular (Tables II and III). Severalgenes associated with apoptosis were upregulated in response to both acuteand chronic exposures. In addition, genes associated with immune responseand protein folding appeared to be oppositely regulated, with those alteredin response to the acute exposure upregulated and those altered in responseto the chronic exposure significantly downregulated and the opposite occurringin protein folding genes. Several genes associated with protein transport weredifferentially expressed in response to both treatments: some were upregulatedand some downregulated. In gonad, similarities in GO category were restrictedto immune response and included both upregulated and downregulated genes[Fig. 2(a), (b) and Tables IV and V].Genes significantly altered within a GO category are not consistent across
treatments. There were very few individual gene changes that were similaracross treatments (Fig. 1 and Table VI). Only 12 genes were consistently down-regulated in response to both chronic and acute exposures in liver and only sixwere consistently upregulated (Table VI). The MHC class I UBA gene wasvery strongly downregulated in liver in response to both acute and chronicmethylmercury treatments (Table VI). Its variation among individuals wasgreater in the chronic treatment experiment. In gonad, there was a single gene,similar to embigin homologue, which was consistently downregulated in responseto the two treatments and none that were consistently upregulated (Table VI).The qPCR analysis of two genes, vitellogenin and hsp70, was in agreement
with the results of the microarray analysis. Vitellogenin expression in liver

was not significantly altered in response to either acute or chronic exposure,consistent with microarray results. However, in the chronic exposure group,expression of vitellogenin was extremely variable. One of four males in thechronic exposure control group and two of four males in the chronic exposuremethylmercury-treated group had vitellogenin expression levels c. 1000-foldgreater than the average of the other samples. This is consistent with the cur-rent array data as well as previous results (Klaper et al., 2006). In the acuteexposure groups, males expressing high levels of vitellogenin were notobserved. Expression of hsp70 in liver was not altered in acute or chronic expo-sure group, consistent with microarray data.
DISCUSSION
This study indicates that methylmercury exposures cause molecular changesin liver and gonad that differ with duration of exposure. The downregulationof many genes involved in protein processing in the liver in response to acutemercury exposure suggests a general stress response. In contrast, after chronicexposure, protein folding genes were upregulated and altered protein transportgenes included both upregulated and downregulated genes, suggesting adaptation

ACUTE AND CHRONIC RESPONSES TO METHYLMERCURY 2223

to the mercury-induced stressor. Differences seen between the two exposuretypes could be because of the accumulation of methylmercury in tissues overtime that could lead to an overall increase in methylmercury exposure withtime. Studies have shown that methylmercury excretion rates in fish are veryslow, possibly exceeding the 600 days of the chronic experiment (Trudel & Ras-mussen, 1997). Fish that were harvested in the chronic experiment after 250days had levels of methylmercury that were at or exceeding the oral dose(3�93 mg g�1) of methylmercury (Drevnick & Sandheinrich, 2003) and severalfishes from the longer study that were analysed at the end of the experimentcontained levels of methylmercury that were up to 30 mg g�1 dry mass. Thereis a much smaller chance that the method of delivery (injection in the acuteand oral in the chronic) caused these differences.Oxidative stress, binding to sulfhydryl groups of cellular proteins and dis-
placement of essential metals from metallothionein are well-established mecha-nisms of mercury toxicity that could produce stress in exposed fish (Lyneset al., 2006). Other studies on gene expression related to methylmercury expo-sure have found differential expression of genes associated with oxidativestress. Gonzalez et al. (2005) found changes in the expression of glutathioneS transferase (GST) and superoxide dismutase (SOD) with exposures to meth-ylmercury. However, as noted previously, Gonzalez et al. (2005) treated theirzebrafish at doses that were much higher than the concentrations of methyl-mercury used in the current study. In the previous study, the authors didnot find that these genes were altered with methylmercury exposure (Klaperet al., 2006), and this was also the case for both the treatments in this study,indicating a potential for species differences or for a different mechanismaffecting tissues at lower methylmercury levels.In the study, several of the altered genes point to methylmercury-induced
apoptosis after both acute and chronic exposures either directly or throughassociated pathways. Methylmercury has been shown to cause apoptosis inboth cell culture experiments and whole organism experiments (Drevnicket al., 2006; Usuki et al., 2007). Most closely related to this study, methylmer-cury significantly increased the number of apoptotic follicular cells in ovarianfollicles of fathead minnows exposed to chronic oral doses of methylmercury(Drevnick et al., 2006). This led to a decline in the production of sex steroidsas well as a significant drop in fecundity.The author’s array data indicate differential expression of genes involved in
apoptosis associated, including cell adhesion, phospholipid biosynthesis, sugarmetabolism, interference with gonadotropin pathways, calcium regulation,phospholipid biosynthesis and plasma transport of proteins. A decline in fattyacid synthase mRNA expression was seen in liver in response to the acute ex-posures, and inhibition of fatty acid synthase is known to induce apoptosis(Huang et al., 2000). Caspase genes were upregulated in liver in response toboth acute and chronic methylmercury treatments. Several caspases are knownto be involved in both the initiation of apoptosis (caspase 8,10) and thedestruction of the cells (caspases 3,6,7). Caspase 3 activation in particularhas been found to be associated with methylmercury exposure, leading to apo-ptosis in several types of cells and organs (Nishioku et al., 2000; Robertson &Orrenius, 2000; Usuki et al., 2007). Caspase activation has been shown to be

part of a cascade starting with calcium ion release into cytosol, leading tocytochrome c release and then caspase activation. In this study and Klaperet al. (2006), several genes associated with calcium ion cascades as well as cyto-chrome c were shown to be differentially regulated with exposure. A tumornecrosis factor (TNF)-like factor, also upregulated in liver in response to acuteexposures, is another inducer of apoptosis in cells.Other studies have indicated that oxidative stress is necessary for apoptosis
to occur (Shenker et al., 2002). However, the results indicate that somethingother than oxidative stress may be stimulating apoptosis at these more environ-mentally realistic concentrations. Methylmercury has been found to trigger celldeath by depleting glutathione in the absence of reactive oxygen species (ROS)overproduction (Gatti et al., 2004). It has also been suggested that MeHgcauses apoptosis through acid activation of endonuclease at lower concentra-tions rather than through ROS (Kuo & Lin-Shiau, 2004). These non-oxidativestress mechanisms of apoptosis induction are supported by the data becausethe authors did not observe alterations in genes indicative of oxidative stress.Alterations in genes involved in the immune system in both gonad and liver
in response to both acute and chronic exposures was observed. Methylmercuryhas been shown to be toxic to the mammalian immune system (Shenker et al.,2000). Antigen presentation genes, and especially the MHC class I and IIgenes, were the most frequently altered within this category. In particular,the MHC class I UBA gene was strongly downregulated in liver under bothacute and chronic exposures (Table VI). Mercury exposure has been shownto lead to immune suppression in fish (Sanchez-Dardon et al., 1999) and is alsoassociated with development of autoimmune disease (Havarinasab et al., 2007).These immune system effects may be related to the previously discussed apo-ptosis effects because immune-related cells undergo apoptosis with methylmer-cury exposure (Shenker et al., 1998).This study demonstrates the utility of microarray studies in developing
hypotheses regarding the impact an environmental contaminant may have onan organism. Specifically, the data presented here point to specific hypothesesregarding the mode of action of methylmercury that differs from those pro-posed previously. While data on individual exposures provide a snapshot ofthe physiological status of an organism, conducting time–course experimentssuch as this one can elucidate the changes that occur over time and the poten-tial for adaptation to a stressor. The microarray data presented in this studywill also eventually be used to conduct a direct comparison of the impactsof this environmental stressor v. several others. Compilations of this type ofdata will eventually point to similarities and differences among stressors withcommon and distinct mechanisms of action increasing the utility of microarraydata for environmental risk assessments.
