Project description:Gene expression was quantified in S. cerevisiae cells after 40 hours of LiCl treatment or control conditions. Cells expressing wild type (WT) Hcm1, a stable Hcm1 mutant (Hcm1-3N), or a consitutitvely active, phosphomimetic mutant (Hcm1-8E) were compared to allow the identification of genes whose expression depends upon dynamic phosphorylation of Hcm1. We found that dynamic phosphorylation of Hcm1 is required for expression of Hcm1 target genes in LiCl stress.
Project description:Analysis of mRNA expression in the adrenal glands of rats from two different models of chronic stress: chronic shock (CS) and chronic variable stress (CVS)
Project description:This study was done to know the transcritional changes occuring in mice liver in response to chronic heat stress at 34*c for a period of two weeks. Keywords: Chronic heat stress response on liver gene expression.
Project description:To investigate the potential deleterious impact of chronic stress at molecular level in testicular tissue, we exposed zebrafish males to chronic stress during 21 days, covering around three complete cycles of spermatogenesis in the species
Project description:To investigate the potential deleterious impact of chronic stress at molecular level in the progeny, we exposed zebrafish males to an unpredictable chronic stress protocol during 21 days
Project description:Acute stress provides many beneficial effects whereas chronic stress contributes to a variety of human health problems. The objective of this study was to use a rodent model to uncover hippocampal gene signatures associated with prolonged chronic stress which could potentially serve as biomarkers and therapeutic targets for early diagnosis and pharmacological intervention for stress induced disease. Mice were subjected to restraint stress over 7 consecutive days and gene expression changes in the hippocampus were analyzed at 3, 12 and 24 hours following the final restraint treatment. Data indicated that mice exposed to chronic restraint stress exhibit a differential gene expression profile compared to non-stressed controls. The greatest differences were observed 12 and 24 hrs following the final stress test.
Project description:Chronic psychosocial stress is a risk factor for psychiatric disorders, and genetic factors interact in conferring susceptibility. The chronic social defeat stress (CSDS) mouse model allows identifying factors underlying resilience and susceptibility to chronic psychosocial stress. We used RNA-sequencing to identify genes and pathways affected by CSDS in three brain regions: medial prefrontal cortex (mPFC), ventral hippocampus (vHPC), and bed nucleus of the stria terminalis (BNST), of male mice from strains C57BL/6Crl and DBA/2Crl.
