Project description:Dendrobium officinale is a common and expensive traditional Chinese medicine used as a medicinal agent and food that has immunoregulatory and anti-inflammatory effects. Methods to authenticate D. officinale are lacking. Although chemical profiles of D. officinale were published, transcriptomic profiling is lacking. Here, we collected D. officinale from two regions (Yunnan and Miandian) and the analogue D. compactum. The Yunnan samples had three different quality levels. All samples were subjected to genome-wide biological response fingerprinting (BioReF) in RAW264.7 cells using RNA sequencing.

Project description:Comparative evaluation of the microbial communities of Yunnan tobacco leaves
Project description:Rates of esophageal adenocarcinoma are rising globally, with risk factors including a range of genetic and environmental factors, including obesity, tobacco smoking, TP53 mutations, and Barrett’s esophagus, a proinflammatory condition which often occurs prior to developing adenocarcinoma. Interestingly, these factors also modulate the gastrointestinal microbiome. To better understand the linkage between the microbiome, inflammation, and development of esophageal adenocarcinoma, we integrated 16S and RNA sequencing data. We found several microbial taxa enriched in tumor samples which were correlated with predicted immune cell infiltration from RNA-seq data, including a decrease in megakaryocyte-erythroid progenitor cells with a concomitant increase in platelets. These data suggest dysbiosis of the intratumoral microbiome promotes development and production of platelets, which reveal alterations in the immune microenvironment of esophageal adenocarcinoma and suggest novel therapeutic targets.
