Objective and Methods Lung cancer has a fastest growing rate of morbidity and mortality among malignant tumors and poses a great threat to the human health. Chemotherapy, as one
Background and Objective Lung cancer is the most lethal malignangy that threatens human heath and lives nowadays in the world, and meanwhile is also the one with worst
Background and Objective Invasion and metastasis is not only the malignant phenotypes of lung cancer but also the main cause of death. To study and elucidate the molecular mechanism
目的:观察并探讨p16、cyc lin D1基因在原发性肺癌组织中的表达水平及其与肿瘤病理生物学行为等的关系。方法:采用S-P免疫组化方法检测68例原发性肺癌标本中p16、cyc lin D1蛋白的表达。结果:原发性肺癌中p16蛋白表达阳性率显著低于癌...目的:观察并探讨p16、cyc lin D1基因在原发性肺癌组织中的表达水平及其与肿瘤病理生物学行为等的关系。方法:采用S-P免疫组化方法检测68例原发性肺癌标本中p16、cyc lin D1蛋白的表达。结果:原发性肺癌中p16蛋白表达阳性率显著低于癌旁组织(P<0.05);cyc lin D1在原发肺癌中的阳性率显著高于癌旁组织(P<0.05)。二者表达与肿瘤大小、淋巴结转移、病理分级及疾病分期密切相关(P<0.05),且二者表达显著负相关(P<0.05)。结论:在原发型肺癌中存在抑癌基因p16编码蛋白的表达下调以及原癌基因cyc lin D1表达上调,与肿瘤的进展密切相关。提示二者可能通过影响细胞周期调控在肺癌的发生发展过程中起重要作用。展开更多
