[Expression of Cyclooxygenase-2 in Patients With Snow-White Sign of Advanced Colorectal Adenomas].

Objective To analyze the expression of cyclooxygenase-2 (COX-2) in the patients with snow-white sign of advanced colorectal adenoma (ACA) and explore its clinical significance.Method Western blotting was employed to determine the expression of COX-2 in the adenoma tissue and the normal tissue adjacent to the adenoma tissue (>5 cm away from the distal end of the adenoma tissue) of 40 ACA patients with snow-white sign and 40 ACA patients without snow-white sign.Results The appearance of snow-white sign in ACA patients was associated with patient age (=0.

CIRC_0085323 SILENCING INHIBITS TNF-Α-INDUCED NORMAL HUMAN COLONIC EPITHELIAL CELL INFLAMMATION AND APOPTOSIS THROUGH THE MIR-495-3P/TRAF3 AXIS.

Background: Previous data have suggested the involvement of circular RNA (circRNA) in ulcerative colitis (UC) development. However, the role and mechanism of circ_0085323 in UC occurrence have not been reported. Methods: Normal human colonic epithelial cells (NCM460) were treated with TNF-α to simulate UC-like cell inflammation and injury in vitro.
