“…miRNA, as a posttranscriptional regulator, modulates gene expression by binding to the 3′UTR of target mRNA in almost all cells, thereby affecting biological processes, development stages, and molecular functions. Moreover, studies have demonstrated that the development and biological functions of the intestine, including renewal, homeostasis, and inflammation, are regulated by miRNAs, as is the case with other tissues [21][22][23][24]. miR-34a and miR-320a strengthens intestinal barrier function by regulating tight-junction proteins in inflammatory bowel disease [25,26].…”
