查询词典 Gene

Methods: In order to study P〓、P〓 and bcl-2 gene expression and its significance in tumorgenesis of lung cancer, the expression of P〓、P〓 and bcl-2 gene was detected by RT-PCR, PCR-SSCP and immunhistochemistry SABC in 65 cases of lung cancer tissues, tissues adjacent to carcinoma and normal tissues, its correlation to clinico-pathological features and prognosis of lung cancer was explored.

因此人们预测其重要性不亚于RB和P〓基因，甚至比其更为重要。Bcl-2基因是继促进细胞生长的癌基因和突变的抑癌基因之后，近年来发现的第三类肿瘤基因，它是一种调控细胞死亡的"存活基因"，可抑制细胞的程序化死亡，故称之为细胞凋亡抑制基因，在肿瘤发生、发展中起着重要的作用。
