Project description:Transcriptome analysis was performed on the rhizome tissues of Atractylodes macrocephala under different treatments. The four treatments were: sterile water irrigation alone, FS root irrigation, FS and AM201 root irrigation, and FS combined with methyltobuzin (TM) root irrigation. And the differential genes between AM201 and FO groups were identified and compared, which helps to reveal the resistance mechanism of AM201 to Atractylodes macrocephala root rot disease

Project description:Atractylenolide II (AT-II), the major bioactive compound of Atractylodes macrocephala exhibits anticancer activity against many types of tumors, but the roles and the potential mechanisms in endometrial cancer remain unclear. To explore a novel therapeutic target of AT-II for the clinical therapy of endometrial cancer, the high-throughput sequence was performed.

Project description:Ulcerative colitis (UC), a subtype of inflammatory bowel disease (IBD), is characterized by chronic and relapsing mucosal inflammation initiating in the rectum and extending upward through part or the entire colon in a continuous fashion. Currently, 5-aminosalicylic acid agents, corticosteroids, immunomodulators, and surgery are the main treatments for UC, which are limited in clinical practice due to common nonadherence, serious adverse effects and heavy financial burden. Atractylodes macrocephala Koidz. (Baizhu) has been used for improving gastrointestinal function and treating digestive disorders for thousands of years, and is currently one of the most frequently used traditional Chinese medicines for the treatment of UC. The purpose of this study was to evaluate the effect and underlying mechanism of polysaccharide from Atractylodes macrocephala Koidz. (PAMK) on UC based on a mouse model of dextran sodium sulfate (DSS)-induced colitis. To investigate the mechanism of therapeutic effect of PAMK on colitis, we performed the microarray analysis of colonic tissues in Control, DSS and DSS+PAMK groups. The results indicated that the beneficial effect of PAMK on DSS-induced colitis may rely on the regulation of the immune response.

Project description:Opioids such as morphine have many beneficial properties as analgesics, however, opioids may induce multiple adverse gastrointestinal symptoms. We have recently demonstrated that morphine treatment results in significant disruption in gut barrier function leading to increased translocation of gut commensal bacteria. However, it is unclear how opioids modulate the gut homeostasis. By using a mouse model of morphine treatment, we studied effects of morphine treatment on gut microbiome. We characterized phylogenetic profiles of gut microbes, and found a significant shift in the gut microbiome and increase of pathogenic bacteria following morphine treatment when compared to placebo. In the present study, wild type mice (C57BL/6J) were implanted with placebo, morphine pellets subcutaneously. Fecal matter were taken for bacterial 16s rDNA sequencing analysis at day 3 post treatment. A scatter plot based on an unweighted UniFrac distance matrics obtained from the sequences at OTU level with 97% similarity showed a distinct clustering of the community composition between the morphine and placebo treated groups. By using the chao1 index to evaluate alpha diversity (that is diversity within a group) and using unweighted UniFrac distance to evaluate beta diversity (that is diversity between groups, comparing microbial community based on compositional structures), we found that morphine treatment results in a significant decrease in alpha diversity and shift in fecal microbiome at day 3 post treatment compared to placebo treatment. Taxonomical analysis showed that morphine treatment results in a significant increase of potential pathogenic bacteria. Our study shed light on effects of morphine on the gut microbiome, and its role in the gut homeostasis.
