Outline of Final Research Achievements |
Our study demonstrates that oral absorption of tacrolimus (an immunosuppressant) was increased in dextran sodium sulfate (DSS)-induced ulcerative colitis rats, and this is attributable to decreased intestinal P-glycoprotein. In addition, the altered expression of miRNAs in the small intestine were observed in DSS-induced ulcerative colitis rats. MiRNAs regulate the expression and function of proteins regulating pharmacokinetics in intestinal epithelial cells. Therefore, miRNAs could be significant factors affecting inter- and intra- individual variations in the pharmacokinetics of tacrolimus.
