Project description:Prenatal stress (PS) could cause depression of offprsing. Here, relative quantitative phosphoproteomics of hippocampus of PS-S and CON offspring rats were performed using LC-MS/MS to confirm known pathways and identify new areas of depression. A total of 6,790 phosphopeptides, 9,817 phosphorylation sites and 2978 phosphoproteins were detected. Among the 2978 phosphoproteins, 1760 (59.09%) with more than two phosphorylated sites, ENSRNOP00000023460 protein has more than 117 phosphorylated sites, and the average distribution of modification sites per 100 amino acids was 2.97. There were 197 different phophpeptides, including 140 increased phosphopeptides and 57 decreased phosphopeptides in PS-S offspring rats when compared to the CON offspring rats. These differential phosphopeptides corresponded to 100 upregulated and 44 downregulated phosphoproteins respectively. GO enrichment analysis these different phosphoproteins in the first five enrichments of CC category, MF category and BP category were involved in a total of 35 different phosphoproteins and these phosphoproteins were mainly related to myelin, microtubule and synapse associated proteins. The first five enrichment of KEGG pathways were found to be involved in many essential biological pathways, and the first five pathways included amphetamine addiction, insulin secretion, cushing syndrome and circadian entrainment signaling pathway. And these first five pathways were related to nine proteins including Adcy9, Apc, Cacna1c, Camk2a, Camk2b, Camk2g, Ctnnd2, Grin2a, Stx1a. Further research is needed to understand the precise role of these pathways in the depressive-like behavior of offspring rats caused by PS.

Project description:The present study investigated arsenic’s effects on mummichogs (Fundulus heteroclitus), while also examining what role that gender or age of exposure might play. Adult male and female mummichogs were exposed to 172ppb, 575ppb, or 1,720ppb arsenic as sodium arsenite for 10 days immediately prior to spawning. No differences were noted in the number or viability of eggs between the groups, but there was a significant increase in deformities in the 1,720ppb arsenic exposure group. Total RNA from adult livers or 6-week-old juveniles was used to probe custom macroarrays for changes in gene expression. In females, 3% of the genes were commonly differentially expressed in the 172 and 575ppb exposure groups. In the males, between 1.1-3% of the differentially expressed genes were in common between the exposure groups. Several genes, including apolipoprotein, serum amyloid precursor, lysozyme, and tributyltin-binding protein, were commonly expressed in either a dose-responsive or dose-specific, but across genders, manner. These patterns of regulation were confirmed by QPCR. These findings will provide us with a better understanding of the effects of dose, gender, and exposure age on the response to arsenic.

Adult mummichogs (Fundulus heteroclitus) were exposed to either 0 or 1,720ppb sodium arsenite for 10 days before the full moon. Each treatment group had 5 20-gallon plastic tanks with 2 male and 5 female fish per tank. The fish were exposed via a static renewal, with renewals every 48 hours. Mummichogs were housed at 25C in a 14/10 light/dark cycle at 18% salinity. On the 3 days surrounding the full moon, spawning substrates were provided and eggs collected. Adult males: After the last day of egg collection, the adults were euthanized. The livers were removed from the males, placed in TRI-Reagent® for RNA isolation (Sigma Chemical Co, St. Louis, MO), and then stored at -80C. Juveniles: Eggs were transferred to clean water and allowed to hatch. The juveniles were grown out in clean water for 6 weeks and then were euthanized. Whole juveniles (7-10 per exposure per tank) were placed in TRI-Reagent® for RNA isolation (Sigma Chemical Co, St. Louis, MO), and then stored at -80C.
