As a newly identified and characterized gene, p42.3 is associated with cell proliferation tumorigenicity. The expression of upregulated in human gastric cancer (GC), but its underlying mechanisms action are not well understood. MicroRNAs (miRNAs) known to play vital regulatory roles many cellular processes. Here we utilized bioinformatics experimental approaches investigate the relationship between miRNAs gene. We showed that miR-29a could repress at both mRNA protein levels via directly...

Abstract Colorectal adenoma (CRA) is the precursor lesion of colorectal cancer (CRC). Several agents have been shown to be effective in chemoprevention CRA recurrence, but there has little research on its primary prevention. Participants older than 50 years with no adenomas were recruited for our study and randomized receive either 1 mg/day folic acid supplement or treatment without acid. After 3 follow-up, plasma folate colonoscopy evaluated. Seven hundred ninety-one participants (91.98%)...

Non-alcoholic fatty liver (NAFL) has the potential to progress non-alcoholic steatohepatitis (NASH) or promote type 2 diabetes mellitus (T2DM). However, NASH and T2DM do not always develop coordinately. Additionally, there are no definite noninvasive methods for diagnosis currently. We established rat models of NAFL, NASH, NAFL + recapitulate different phenotypes associated with disease (NAFLD) its progression. Histologic features livers were scored according criteria by Nonalcoholic...
