Project description:MAF from pika Epas1-3FLAG knock-in mice were extracted and immortalized. After 12h DMOG treatment, cells were conducted for the ChIP-seq (Bmal1,Flag). We found that in knock-in mice fibroblasts, EPAS1-3FLAG can bind to similar E-box locus compared with BMAL1. Fibroblasts from mouse, rat, rabbit and Tibetan pika were extracted (and Tibetan pika fibroblasts were immortalized). RNA was extracted at 90% confluency. We found that Per2 mRNA level was significantly lower in Tibetan pika fibroblasts compared with other species.
Project description:The increased consumption of various beverages has been paralleled by an epidemic of several intestinal diseases around the world, such as inflammatory bowel disease (IBD), irritable bowel syndrome (IBS) and colorectal cancer. Mounting evidence have shown that excessive consumption of beverages increases the risk of IBD and IBS. In addition, sugar-sweeter, food additives and food ingredients were identified to play important roles in these conditions. Consuming cold beverage is common among some people, especially in the youngsters. However, whether the cold stress contribute directly to host metabolism, gut barrier and gut-brain axis is unclear. In an intestinal function disorder model induced by cold water in mice, we investigated changes in gut transit, anxiety and depression like behavior. To evaluate the effect of cold water on gut barrier, we investigate the tight junctions in the colon. In addition, we employed RNA sequencing transcriptomic analysis to identify genes potentially driving the gut injury, and in parallel, examine the gut microbiota and metabolites in the feces.In an intestinal function disorder model induced by cold water in mice, we investigated changes in gut transit, anxiety and depression like behavior.

Project description:Background: Probiotic-like bacteria treatment has been described to be associated with gut microbiota modifications. Goal: To decipher if the effects of the tested probiotic-like bacteria are due to the bacteria itself or due to the effects of the bacteria on the gut microbiota. Methodology: In this study, gut microbiota has been analyzed from feces samples of subjects with metabolic syndrome and treated with one of the 2 tested probiotic-like bacteria or with the placebo during 3months.
