Project description:Delineating the molecular basis of individual differences in the stress response is critical to understanding the pathophysiology and treatment of posttraumatic stress disorder (PTSD). In this study, 7 d after predator-scent-stress (PSS) exposure, male and female rats were classified into vulnerable (i.e., M-bM-^@M-^\PTSD-likeM-bM-^@M-^]) and resilient (i.e.,minimally affected) phenotypes on the basis of their performance on a variety of behavioral measures. Genome-wide expression profiling in blood and two limbic brain regions (amygdala and hippocampus), followed by quantitative PCR validation, was performed in these two groups of animals, as well as in an unexposed control group. Differentially expressed genes were identified in blood and brain associated with PSS-exposure and with distinct behavioral profiles postexposure. There was a small but significant between-tissue overlap (4M-bM-^@M-^S21%) for the genes associated with exposure-related individual differences, indicating convergent gene expression in both sexes. To uncover convergent signaling pathways across tissue and sex, upstream activated/deactivated transcription factorswere first predicted for each tissue and then the respective pathways were identified. Glucocorticoid receptor (GR) signaling was the only convergent pathway associatedwith individual differences when using the most stringent statistical threshold. Total RNA obtained from hippocampus of rats exposed to predator-scent-stress and showing extreme (n=5 males and n=5 females) or minimal (n=5 males and n=5 females) behavioral response compared to unexposed to stress and behaviorally tested controls (n=5 males and n=5 females).

Glucocorticoid receptor (GR) signaling was the only convergent pathway associatedwith individual differences when using the most stringent statistical threshold. Total RNA obtained from whole blood of female rats exposed to predator-scent-stress and showing extreme (n=8 males and n=8 females) or minimal (n=8 males and n=8 females) behavioral response compared to unexposed to stress and behaviorally tested controls (n=8 males and n=7 females).

Project description:In the field, adult male rodents are more frequently infected with hantaviruses than females. Early data suggests that sex steroid hormones modulate sex differences in host immune response. This project focuses on elucidating sex differences in gene expression in the lungs of infected males 15 and 40 days post infection with Seoul virus (naturally occurring hantavirus in Norway rats) relative to infected females 15 and 40 days post infection on 12 RG_U34 GeneChips.

Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.
