摘要
Objective： To investigate the dys-psychological stress effect on the growth of subcutaneous xenotransplanted tumor in nude mice bearing human epithelium ovarian carcinoma, and the influence on P53 and NFκBp65 expressions. Methods： The subcutaneous tumor xenografts were established by implanting human epithelium ovarian carcinoma tissues into nude mice and the dys-psychological stress model was established with restraint. The mice were randomized into the following four treatment groups with each group six mice respectively： tumor group （group A）, normal saline intraperitoneal injection; tumor with stress group （group B）, normal saline intraperitoneal injection; tumor therapy group （group C）, cisplatin intraperitoneal injection; and tumor therapy with stress group （group D）, cisplatin intraperitoneal injection. The expressions of P53 and NFκBp65 in tumor tissues were determined by Western blotting. Results： The expressions of P53 and NFκBp65 in each restraint group were enhanced compared with the control groups （P0.05）. Conclusion： The dys-psychological stress may induce the high expressions of P53 and NFκBp65 proteins and further promote tumor growth.
