Recently, an interesting study entitled “MiR-21 regulates epithelial–mesenchymal transition
in intestinal fibrosis of Crohn's disease by targeting PTEN/mTOR” was published in
Digestive and Liver Disease [
[1]
]. In this study, the authors revealed that miR-21 was significantly upregulated in
the intestinal tissues from Crohn's disease (CD) patients with fibro stenosis. They
further showed that miR-21 inhibition with antagonists relieved intestinal fibrosis,
which is established by suppressing epithelial–mesenchymal transition (EMT) and regulating
extracellular matrix (ECM) remodeling. Their results established and clarified the
critical role of miR-21 in CD that may be beneficial in providing a potential therapeutic
target against CD. Although this novel discovery opens the door for new treatment
of CD, it is not known whether miR-21 inhibition represses the development of CD only
by suppressing EMT and regulating ECM remodeling, and whether inhibition of miR-21
could produce unwanted side effects.To read this article in full you will need to make a payment
