Abstract

The invention discloses a kit for postoperative and prognosis evaluation of liver cancer, and relates to the field of biological medicine. The kit comprises an agent for quantitatively detecting an expression level of micro RNA (Ribonucleic Acid) molecules miR-653 in to-be-detected liver tissues; a nucleotide sequence of the miR-653 is as shown in Seq ID No.1. Active ingredients of a liver cancer chemosensitizer comprise the mutually prepared micro RNA molecules miR-653 and a precursor of the micro RNA molecules miR-653, or an overexpression vector capable of effectively expressing the micro RNA molecules miR-653 and / or the precursor of the miR-653; the precursor of the micro RNA molecules miR-653 is encoded by a DNA (Deoxyribose Nucleic Acid) sequence as shown in Seq ID No.2. Experimental data verify the effectiveness of the kit disclosed by the invention in the aspect of postoperative and prognosis evaluation of liver cancer and verifies that the sensitizer based on the miR-653 can effectively reinforce the sensitivity of liver cancer cells for a chemotherapy drug sorafenib.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a postoperative prognosis assessment kit for liver cancer and a chemotherapy sensitizer for liver cancer. Background technique [0002] Hepatocellular carcinoma (HCC, hereinafter referred to as liver cancer) is a malignant tumor disease that seriously threatens the life and health of our people. Worldwide, liver cancer has become the third leading cause of cancer-related death. In recent years, imaging diagnostic techniques and surgical techniques related to liver cancer have been continuously improved. Targeted therapy drugs for liver cancer represented by sorafenib have also been approved by the US Food and Drug Administration. These achievements provide more and more effective options for the diagnosis and treatment of liver cancer. But unfortunately, looking at the current clinical treatment of liver cancer, the five-year survival rate of liver cancer patients has not been signi...
