The functions of chloride channels in preconditioning-induced cell protection remain unclear. In this report, we show that the volume-activated chloride channels play a key role in hydrogen peroxide (H2O2) preconditioning-induced cell protection in pheochromocytoma PC12 cells. The preconditioning with 100 μM H2O2 for 90 min protected the cells from injury induced by ...

Abstract Introduction. Aneuploidy has been suggested as independent prognostic marker in ulcerative colitis (UC) patients for developing UC-associated colorectal carcinomas (UCCs). UCCs are associated with a poorer prognosis and more frequently present with synchronous carcinomas when compared with sporadic colorectal carcinomas (SCCs). The authors therefore investigated if the adjacent non-malignant ...

The human Apurinic/apyrimidinic endonuclease 1 (hAPE1) is an essential enzyme, being the main abasic endonuclease in higher eukaryotes. However, many evidences show that hAPE1 can directly bind specific gene promoters, thus modulating their transcriptional activity, even in the absence of specific DNA damage. Recent findings, moreover, suggest a role for ...
