Project description:Whether myogenesis is affected by the maternal gut dysbacteriosis still remains ambiguous. In this study, firstly we show elevated level of lipopolysaccharides (LPS) in a gut microbiota dysbiosis mouse model. Secondly, we demonstrate that the diameter of muscle fibres, limb development and somitogenesis were inhibited in both gut microbiota dysbiosis and LPS exposed mice and chicken embryos. These might be due to LPS disturbed the cell survival and the key genes which regulating the somitogenesis and myogenesis. RNA sequencing and subsequent validation experiments verified that retinoic acid (RA) signaling perturbation was mainly responsible for the aberrant somite formation and differentiation. Subsequently, we found that LPS-induced Roxidative stress (ROS generation and antioxidant genes such as Nrf2, AKR) contributed to the above-mentioned interference with RA signaling. These findings highlight that the gut microbiota homeostasis also involved in regulating the development of muscle progenitor cells during pregnancy.

Project description:Early-weaning-induced stress causes diarrhea, thereby reduces growth performance of piglets. Gut bacterial dysbiosis emerges as a leading cause of post-weaning diarrhea. The present study was aimed to investigate the effect of capsulized fecal microbiota transportation (FMT) on gut bacterial community, immune response and gut barrier function of weaned piglets. Thirty-two were randomly divided into two groups fed with basal diet for 21 days. Recipient group was inoculated orally with capsulized fecal microbiota of health Tibetan pig daily morning during whole period of trial, while control group was given orally empty capsule. The results showed that the F/G ratio, diarrhea ratio, diarrhea index, and histological damage score of recipient piglets were significantly decreased. FMT treatment also significantly increased the colon length of piglets. Furthermore, the relative abundances of Firmicutes, Euryarchaeota, Tenericutes, Lactobacillus, Methanobrevibacter and Sarcina in colon of recipient piglets were increased, and the relative abundances of Campylobacter, Proteobacteria, and Melainabacteria were significantly decreased compared with control group.

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:We have previously demonstrated that the gut microbiota can play a role in the pathogenesis of conditions associated with exposure to environmental pollutants. It is well accepted that diets high in fermentable fibers such as inulin can beneficially modulate the gut microbiota and lessen the severity of pro-inflammatory diseases. Therefore, we aimed to test the hypothesis that hyperlipidemic mice fed a diet enriched with inulin would be protected from the pro-inflammatory toxic effects of PCB 126.
