环氧化酶2(cyclooxygenase-2,COX-2)是1991年由Xie等分离出的一种诱导型酶,近年来已成为肿瘤研究的热点之一。但国内、外对其在胃癌中作用的研究还较少。因此,了解COX-2在胃癌中的表达和促进胃癌发生的分子机制有着重要的意义。1COX-2概述COX又称前列腺素内过氧化物合成酶(PGHS
Cyclooxygenase-2 (COX-2) is an inducible enzyme isolated from Xie et al in 1991 and has become one of the hot topics in cancer research in recent years. However, domestic and foreign research on its role in gastric cancer is still less. Therefore, to understand the expression of COX-2 in gastric cancer and to promote the molecular mechanism of gastric cancer is of great significance. 1COX-2 Overview COX, also known as prostaglandin endoperoxide synthase (PGHS
