Abstract

The invention provides PDCD11-shRNA. The PDCD11-shRNA is a shRNA molecule which is designed according to a gene sequence of nucleolin PDCD11 and targets to PDCD11; and the PDCD11-shRNA can remarkablyinhibit the growth of human colorectal cancer cells HCT116. The sequence of the PDCD11-shRNA disclosed by the invention is as shown in SEQ ID No. 1. The PDCD11-shRNA of the invention has the advantages that the expression level of PDCD11 in HCT116 tumor cells can be remarkably reduced, and the proliferation rate of the cells is remarkably inhibited. Therefore, the shPDCD11 molecule designed by theinvention has the potential of treating colorectal cancer.

Description

technical field [0001] The invention relates to a PDCD11-shRNA and its application as a therapeutic target for colorectal cancer, the classification number is C12N15 / 113, and belongs to the technical field of biomedicine. Background technique [0002] Colorectal cancer is currently one of the most common malignant tumors of the digestive tract, which seriously threatens human life and health. Its incidence rate ranks in the forefront of common malignant tumors, and its case fatality rate also ranks in the forefront of cancer deaths. The occurrence and development of colorectal cancer is a multi-step, multi-stage and multi-gene process, in which the abnormal expression of genes plays an important role in the development of colon cancer. Therefore, it is of great scientific significance to find new therapeutic targets for colorectal cancer to treat the disease and reduce the mortality rate of colorectal cancer. [0003] Targeted tumor therapy is to design and develop targeted...
