Project description:To explore the gene expression prolife in the chroniclly hypoxic myocardium, 8 rats were divided randomly into normoxic (n=4) or chroniclly hypoxic (n=4) group, and were exposed to room air (21% O2) or continued hypoxia (10% O2) for 4 weeks. Heart tissues were collected and RNA sequencing was applied to detect the overall gene expression prolife. Genes with adjusted P-value ≤0.01 (corrected by Benjamini-Hochberg) and |log2_ratio|≥0.585 are identified as differentially expressed genes. RNA sequencing identified a total of 2014 gene with statistical significances, among which 1260 genes were significantlly increased and 754 genes were significantlly decreased. The results showed that gene expression profiling was perturbed in chronically hypoxic myocardium.
Project description:We hypothesize that changes in adrenal gene expression mediate the increased plasma corticosterone and steroidogenesis in rat pups exposed to hypoxia from birth. Experiment Overall Design: In the current study, rat pups (with their dams) were exposed to hypoxia from birth and compared to pups from normoxic dams fed ad libitum. Adrenal glands were collected from normoxic and hypoxic pups at PD7and pooled (N=24/sample; 4 samples per treatment group) for total RNA extraction. Microarray analysis was performed, followed by verification with real-time PCR. Furthermore, the expression of selected genes involved in adrenal function was analyzed by real-time PCR, regardless of microarray results.

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.
