摘要

在印度,烟草消费导致了男性一半的癌症和女性四分之一的癌症。本研究主要探讨环氧化酶-2 (COX-2)、P53、血管内皮生长因子(VEGF)和一氧化氮合酶(NOS)的表达及其与口腔、食管、肺和胃中烟草相关恶性肿瘤生长和血管生成的关系。本研究进一步评估尼古丁的致癌作用,并探讨COX-2和NOS-2过表达是否通过其受体参与肿瘤生长和相关血管生成性VEGF表达。材料与方法对140例口腔癌、食管癌、胃癌和肺癌的活检标本进行了横断面研究。免疫组化评价p53、COX-2、VEGF及诱导NOS。对研究结果的显著性进行统计学分析。结果免疫组化评价了COX-2、NOS-2、VEGF和p53在烟草和非烟草相关病例中的表达模式。本研究结果显示,COX-2、NOS-2、VEGF和p53在所有恶性肿瘤中均上调。结论p53蛋白的积累和COX-2、NOS-2、VEGF表达的增加可能通过促进血管生成参与了肿瘤的发生和侵袭性。在肿瘤发生过程中,尼古丁可能对COX-2和P53表达有显著影响。这些数据可能对使用COX-2、NOS-2和VEGF抑制剂以及p53基因治疗烟草相关恶性肿瘤的未来抗癌治疗策略具有重要意义。

Evaluation of Cyclooxygenase-2, P53, Vascular Endothelial Growth Factor, and Nitric Oxide Synthase-2 in Angiogenesis and Growth of Tobacco-Related Malignancies
Abstract Introduction In India, tobacco consumption is responsible for half of all the cancers in men and a quarter in women. The present study focuses on the expression of cyclooxygenase-2 (COX-2), P53, vascular endothelial growth factor (VEGF), and nitric oxide synthase (NOS) and their relationship with the growth and angiogenesis of tobacco-related malignancies of the oral cavity, esophagus, lungs, and stomach. It further evaluates the carcinogenic action of nicotine and examines whether COX-2 and NOS-2 overexpression is responsible for tumor growth and associated angiogenic VEGF expression via its receptor. Material and Methods A cross-sectional study on 140 biopsies, resected specimens of cancer of oral cavity, esophagus, stomach, and lungs, was done. Immunohistochemical evaluation for p53, COX-2, VEGF, and inducible NOS was done. Relevant statistical analysis was applied for the significance of the findings. Results Immunohistochemical evaluation of pattern of expression of COX-2, NOS-2, VEGF, and p53 was done in both tobacco- and nontobacco-associated cases. The results of the present study revealed an upregulation of COX-2, NOS-2, VEGF, and p53 in all the malignancies. Conclusion The present results indicated that p53 protein accumulation and increased expression of COX-2, NOS-2, and VEGF might be responsible for carcinogenesis and tumor aggressiveness by enhancing angiogenesis. A possible significant effect of nicotine on COX-2 and P53 expression in tumorigenesis is revealed. These data might have important implications for the therapeutic use of COX-2, NOS-2, and VEGF inhibitors as well as of p53 gene therapy in future anticancer therapeutic strategies in tobacco-related malignancies.
