Project description:For RNA-seq experiments, 20 embryos were placed into 5 mL final volume of sterile ERM. Each treatment group were exposed within a 10-minute window. Exposure groups included ERM, [100 ng/L AVS or 1 µg/L AVS] or [100 ng/L or 1 µg/L afidopyropen] (N=5 beakers per treatment). On 7 days post fertilization (dpf), fish were transferred to a labeled and pre-weighed 1.7 mL tube. The tube was then immediately flash frozen in liquid nitrogen prior to RNA-seq analysis.

Project description:Pharmaceutical chemicals used in human medicine are released into surface waters via municipal effluents and pose a risk for aquatic organisms. Among these substances are selective serotonin reuptake inhibitors (SSRIs) which can affect aquatic organisms at sub ppb concentrations. To better understand biochemical pathways influenced by SSRIs, evaluate changes in the transcriptome, and identify gene transcripts with potential for biomarkers of exposure to SSRIs; larval zebrafish Danio rerio were exposed (96 h) to two concentrations (25 and 250 µg/L) of the SSRIs, fluoxetine and sertraline, and changes in global gene expression were evaluated (Affymetrix GeneChip® Zebrafish Array). Significant changes in gene expression (>=1.7 fold change, p<0.05) were determined with Partek® Genomics Suite Gene Expression Data Analysis System and ontology analysis was conducted using Molecular Annotation System 3. The number of genes differentially expressed after fluoxetine exposure was 288 at 25 µg/L and 131 at 250 µg/L; and after sertraline exposure was 33 at 25 µg/L and 52 at 250 µg/L. Five genes were differentially regulated in all treatments relative to control, suggesting that both SSRIs share some similar molecular pathways. Among them, expression of the gene coding for FK506 binding protein 5 (FKBP5), which is annotated to stress response regulation, was highly down-regulated in all treatments (results confirmed by qRT-PCR). Gene ontology analysis indicated that regulation of stress response and cholinesterase activity were critical functions influenced by these SSRIs, and suggested that changes in the transcription of FKBP5 or acetylcholinesterase could be useful biomarkers of SSRIs exposure in wild fish. Zebrafish (Danio rerio) were obtained from the Zebrafish Research Facility maintained at the Center for Environmental Biotechnology at the University of Tennessee. Fish husbandry, spawning, and experimental procedures were conducted with approval from the UT Insititutional Animal Care and Use Committee (Protocol #1690-1007). Water for holding fish and conducting experiments (hereafter referred to as fish water) consisted of MilliQ water (Millipore, Bedford, MA) with ions added: 19 mg/L NaHCO3, 1 mg/L sea salt (Instant Ocean Synthetic Sea Salt, Mentor, OH), 10 mg/L CaSO4, 10 mg/L MgSO4, 2 mg/L KCl. Embroyos were obtained by spawning adult fish with no history of contaminant exposure. Fertilization of embryos took place at the same time (<15 minutes), such that larvae used in experiments were of similar age at the time of exposure. All activities (maintenance of adult fish, spawning, and experiments) were conducted in an environmental chamber with a temperature of 27 +/- 1 C and 14:10h light:dark photoperiod. Larval zebrafish (72 hpf) were exposed for 96 h in 200ml fish water containing appropirate amount of SSRI stock (i.e. fluoxetine or sertraline). There were four SSRIs treatments (25 and 250 ug/L fluoxetine and 25 and 250 ug/L sertraline) and one control (no SSRIs) with triplicate beakers and each beaker contained about 100 larval fish. During exposure for 96 hours, beakers were kept covered to prevent water evaporation and fish were not fed (i.e., fish consumed their yolk sac).

Project description:Arsenic and mercury are known chemical hazards. The differences in effects from organic and inorganic forms of these toxic elements is less well understood, however. The nematode Caenorhabditis elegans (C. elegans) is a suitable model to investigate the toxicity of environmental hazards. In this study, the transcriptomic profiles of C. elegans exposed to inorganic mercury chloride (HgCl2) and sodium (meta)arsenite (NaAsO2) were assessed alongside organic methylmercury chloride (meHgCl) and dimethylarsinic acid (DMA). For this purpose, adult C. elegans were exposed for 24 h to NaAsO2 (10 µg/ml), DMA (200 µg/ml), HgCl2 (2 µg/ml), and meHgCl (0.5 µg/ml), concentrations that were equitoxic in juveniles for developmental delay. Whole genome gene expression profiles were determined by using Cellegans_UnrestrictedGE_G2519F_020186 Microarray (Agilent Technologies, Santa Clara, CA). The results showed significant changes in the transcriptome of adult C. elegans exposed to NaAsO2, DMA, HgCl2, or meHgCl relative to the control group (C. elegans treated with water). A total of 927 and 1221 differentially expressed genes (DEGs) were found in C. elegans treated with 10 µg/ml NaAsO2 or 200 µg/ml DMA, respectively. Interestingly, only 161 DEGs were in common for these two chemicals. Exposure to 2 µg/ml HgCl2 or 0.5 µg/ml meHgCl altered the expression of 670 and 485 genes, respectively, and out of these genes, 154 were commonly altered by the two treatments. Analysis of DEGs revealed that organic and inorganic forms of arsenic and mercury have different effects on the transcriptome of adult C. elegans.

Project description:ERM knockout mice were produced. Testis develop a Sertoli cell only syndrome, which appears complete by 10 weeks of age in male ERM knockout mice. Three sets of Affymetrix comparisons were made. #1 and #2, Wt or ERM knockout testis from 4 week old males, totaly RNA. This time preceeds any significant histologic difference between the wt or knockout. The results was the finding that only a very specific set or markers for spermatogonial STEM CELLs were found to be greatly reduced in the ERM knockout. #3 and #4. The sertoli cell line TM4 was transduced with a retroviral ERM. The wild type TM4 cell line was compared to this TM$-ERM cell line, with the finding that only a few genes were increased in the TM4-ERM line. #5, #6 and #7. Primary Sertoli cells were purified from 4 week old wild type or ERM knockout or from 10 week old ERM knockout mice and compared. Keywords: other
