The loss of tumor suppressor gene and loss of function play a very important role in the development of tumor. In this study, the newly discovered multi-tumor suppressor gene p16 was selected. 31 cases of colon cancer and 22 cases of rectal cancer were detected by immunohistochemical ABC method. And p16 tumor suppressor gene expression in 28 cases of normal colorectal tissue. First, materials and methods Specimen source: (1) experimental group: collect the fourth...
