ARTICLE HIGHLIGHTS
Research background

Intestinal ischemia/reperfusion (I/R) causes local injuries in the intestine and multiple organ dysfunction syndromes or even multiple organ failure in distant organs with a mortality rate ranging from 30%90%. The underlying mechanisms are very complex. preventing intestinal apoptosis is one of the critical targets in treating patients with intestinal I/R injury.

Research motivation

Exploring the mechanism of apoptosis in intestinal I/R injury and preventing intestinal apoptosis is one of the critical targets in treating patients with intestinal I/R injury.

Research objectives

To apoptosis and its mechanism.

Research methods

An intestinal I/R injury model was established in mice with superior mesenteric artery occlusion, and Caco2 cells were subjected to hypoxia/reoxygenation (H/R) for the simulation of I/R in vivo.

Research results

Cystic fibrosis transmembrane conductance regulator (CFTR) overexpression significantly increased the Caco2 cell viability and decreased cell apoptosis induced by the H/R. And CFTR overexpression could reverse the decreased PI3K/AKT expression induced by the I/R treatment in vivo or H/R treatment in vitro.

Research conclusions

Overexpression of CFTR attenuates H/R-induced apoptosis through PI3K/AKT/NF-κB signaling pathway in H/R-treated Caco2 cells.

Research perspectives

CFTR/PI3K/AKT/NF-κB signaling pathway is potential mechanism to protect intestinal cell from apoptosis in intestinal I/R injury and critical targets in treating patients with intestinal I/R injury.
