摘要:
Objective To investigate the relationship between the expression level of deleted in liver cancer-1 (DLC-1) gene and colon cancer staging or lymph nodes metastatic ratio.Methods Total 60 resection specimens were collected from colon cancer patients between September 2009 and September 2011,and 10 resection specimens from patients with trauma,colonic diverticulitis and colitis were used as the control.The DLC-1 mRNA level was measured with real time quantitative RT-PCR in colon cancer patients and the control group.TNM system was used for colon cancer staging.The linear correlation analysis was performed to determine the relationship between DLC-1 expression level and colon cancer staging or lymph nodes metastatic ratio.Results The mRNA level of DLC-1 was significantly reduced in colon cancer tissues in comparison to that in adjacent normal tissues,while adjacent tissues showed significantly lower DLC-1 level than normal clone tissues.The expression of DLC-1 was negatively correlated with both colon cancer stage and the lymph nodes metastatic ratio (r =0.46,P ＜ 0.05).Conclusions DLC-1 expression was negatively correlated with pathological stage and lymph node metastasis ratio,indicating a critical role of DLC-1 gene in colon cancer genesis,which provide a possible new direction for colon cancer research.
