Project description:Lycium barbarum, a member of the Solanaceae family, has been used for more than 2000 years in the traditional Chinese medicine. L. ruthenicum, endemic to northwestern China, is also used as medicine and has had a great influence on the development of Minority Medicine. Previous studies revealed there are many differences between two species, including morphological and phytochemical differences. However, the molecular mechanism of formation of its fruit and associated medicinal and nutritional components is unexplored. In the present studies, for transcriptomic analyses, fruits from 5 developmental stages L. barbarum and L. ruthenicum were collected. KEGG analyses for the DEGs between L. barbarum and L. ruthenicum, revealed that molecular mechanism of fruit formation were distinct obviously during the development process. Moreover, we found that multiple DEGs enriched in “Phenylpropanoid biosynthesis (ID: ko00940”, “Flavonoid biosynthesis” (ID: ko00941) were up-regulated in L. ruthenicum at different developmental stages of fruit. It suggested that biotic and abiotic stress might be responsible for high abundance of antioxidant capacities in L. ruthenicum.
Project description:This study aimed to analyze changes in gut microbiota composition in mice after transplantation of fecal microbiota (FMT, N = 6) from the feces of NSCLC patients by analyzing fecal content using 16S rRNA sequencing, 10 days after transplantation. Specific-pathogen-free (SPF) mice were used for each experiments (N=4) as controls.
Project description:Habitual exercise modulates the composition of the intestinal microbiota. We examined whether transplanting fecal microbiota from trained mice improved skeletal muscle metabolism in high-fat diet-fed mice. The recipient mice that received fecal samples from trained donor mice for 1 week showed elevated levels of metabolic signalings in skeletal muscle. Glucose tolerance was improved by fecal microbiota transplantation after 8 weeks of HFD administration. Intestinal microbiota may mediate exercise-induced metabolic improvement in mice. We performed a microarray analysis to compare the metabolic gene expression profiles in the skeletal muscle from each mouse.
Project description:We found that low protein diet consumption resulted in decrease in the percentage of normal Paneth cell population in wild type mice, indicating that low protein diet could negatively affect Paneth cell function. We performed fecal microbiota composition profiling. Male mice were used at 4-5 weeks of age. Fecal samples were collected for microbiome analysis.
