So-called ‘‘genetical genomics’’ studies have identified locally acting -eQTLs (cis-eQTLs) for genes that show differences in steady-state RNA levels. These studies have also -identified distantly acting master-modulatory trans-eQTLs that regulate tens or hundreds of transcripts -(hotspots or transbands). We expand on these studies by performing genetical genomics experiments in -two environments in order to identify trans-eQTL thatmight be regulated by developmental exposure to -the neurotoxin lead. Flies from each of 75 RIL were raised from eggs to adults on either control food -(made with 250 mM sodium acetate), or lead-treated food (made with 250 mM lead acetate, PbAc). RNA -expression analyses of whole adult male flies (5–10 days old) were performed with Affymetrix DrosII -whole genome arrays (18,952 probesets). Among the 1389 genes with cis-eQTL, there were 405 genes -unique to control flies and 544 genes unique to lead-treated ones (440 genes had the same cis-eQTLs in -both samples). There are 2396 genes with trans-eQTL which mapped to 12major transbands with greater -than 95 genes. Permutation analyses of the strain labels but not the expression data suggests that the -total number of eQTL and the number of transbands are more important criteria for validation than the -size of the transband. Two transbands, one located on the 2nd chromosome and one on the 3rd -chromosome, co-regulate 33 lead-induced genes, many of which are involved in neurodevelopmental -processes. For these 33 genes, rather than allelic variation at one locus exerting differential effects in two -environments, we found that variation at two different loci are required for optimal effects on leadinduced -expression.</p> -<p class="subtitle">Materials and Methods:</p> -<p>The 75 Drosophila roo lines were obtained from Trudy Mackay. -To avoid batch effects (Zakharkin et al., 2005), the growth of the -flies, the RNA extraction and the order of running the arrays, and -the fluidics well used for each array was completely randomized -for the 75 lines in two treatments. Control food consisted of -standard cornmeal, agar, sugar, yeast, and 250 mM NaAc (Ashburner, -1989). Lead-contaminated food consisted of standard food -plus 250 mM PbAc (lead exposure at this concentration has been -shown to affect locomotion in adults; Hirsch et al., 2003). Flies -from each of the 75 roo lines (20 males and 20 females) were -placed in a vial with 10 ml of food (control or PbAc) for 3 days at -25 8C and allowed to lay eggs; the adults were subsequently -discarded. Newly enclosed adult males were placed on the same -medium (control or PbAc) as had been present during pre-adult -development for 5–10 days before being used as subjects. Male -progeny were pooled from each vial (65 males per vial) and frozen -at 80 8C. RNA samples were extracted in groups of 24 and arrays -hybridization run in groups of 4 with 3 groups run per day. Effects -of RNA extraction and array hybridizations day were examined by -ANOVA and Support Vector approaches and no obvious day effects -were observed.</p> -<p class="subtitle">Data Source Acknowledgements:</p> -<p> -<p>This work was supported by the Environmental Health Sciences -Center in Molecular and Cellular Toxicology with Human -Applications Grant P30 ES06639 at Wayne State University, NIH -R01 grants ES012933 and CA105349 to D.M.R., DK071073 to X.L., -and UAB-CNGI grant to M.D.G.
