TRIM28在結(jié)直腸癌組織中的表達(dá)及其對癌細(xì)胞增殖、遷移能力的影響
[Abstract]:Objective to investigate the expression of (TRIM) 28 in colorectal carcinoma and its effect on the proliferation and migration of cancer cells. Methods Immunohistochemical method was used to detect the relationship between TRIM28, and clinicopathological features and survival prognosis in 145 cases of colorectal cancer and its adjacent tissues. HT29 cells of colorectal cancer were randomly divided into observation group and control group, respectively, transfection of sh TRIM28 down-expression plasmid and no-load control plasmid for 48 h. Western blot assay was used to detect TRIM28, in HT29 cells. The proliferation and migration of HT29 cells were observed by MTT assay and scratch assay. Results the expression of TRIM28 was higher in 97 cases of colorectal cancer than in 4 cases of adjacent tissues (P0.01). Moreover, the expression of TRIM28 in patients with lymph node metastasis, distant metastasis and high Dukes stage was higher than that without lymph node metastasis, distant metastasis and low Dukes stage (P 0.05). The 3-year disease-free survival rate of patients with high TRIM28 expression was 68.0%. 83.3% of the patients with low expression of TRIM28 were lower than those with low expression of TRIM28 (P0.01). Multivariate analysis of COX proportional risk model showed that TRIM28 expression was an independent prognostic factor (HR=3.26,P=0.01) in colorectal cancer patients. The relative expression of TRIM28 in HT29 cells in the observation group was lower than that in the control group (P0.01), and the OD value of proliferation and the migration distance of the cells in the observation group were lower than those in the control group (P0.01). Conclusion the high expression of TRIM28 in colorectal cancer can inhibit the proliferation and migration of colorectal cancer cells, and it may play an important role in the development of colorectal cancer, and it can be used as a prognostic index and a potential therapeutic target in colorectal cancer patients.
