肺癌是近年来发病率最高的恶性肿瘤,成为人类疾病死亡的主要原因之一,肺癌是起始于肺支气管和肺上皮细胞的一种疾病,随着肿瘤分子生物学的深入研究,人们已认识到肺癌的发生发展与细胞凋亡的抑制有关,surv iv in基因是新近发现的一种凋亡抑制蛋白,选择性表达于常见的恶性肿瘤,而 Lung cancer is a malignant tumor with the highest incidence in recent years and has become one of the major causes of human death. Lung cancer is a disease that starts in lung bronchus and lung epithelial cells. With the further study of tumor molecular biology, it has been recognized The occurrence and development of lung cancer is related to the inhibition of apoptosis. The survivin gene is a recently discovered apoptosis-inhibitory protein selectively expressed in common malignant tumors. However,
