Abstract

The invention discloses application of ethyl gallate for preparing drugs for treating colon carcinoma cell Lovo apoptosis. Pharmacology and cell biology experiments show that the ethyl gallate can effectively promote chromatin condensation of colon carcinoma cell Lovo, plasma membrane translocation of phosphatidylserine and breakage of internal DNAs of nucleuses and can induce cell apoptosis, and the action mechanism is closely related to improvement on expression level of Caspase-3, Caspase-8 and Caspase-9 proteins in the cells. The apoptosis-inducing effect of the ethyl gallate on the colon carcinoma cell Lovo is disclosed and subjected to quantitative analysis for the first time, research and development for new drugs with anti-cancer activity from the ethyl gallate from the perspective of apoptosis are benefitted, seeking for prevention and treatment of colon carcinoma diseases is benefitted, and new thoughts are provided for treatment of various tumors.

Description

technical field [0001] The invention relates to the application of ethyl gallate in the preparation of a medicine for treating apoptosis of human colon cancer, belonging to the technical field of cell biology. Background technique [0002] Colorectal cancer is one of the most common malignant tumors of the digestive tract, and its morbidity and mortality rank third among malignant tumors in the world. With changes in human life patterns, food structure, and eating habits, the incidence and mortality of colon cancer The mortality rate is increasing year by year. Facing such a serious social problem, how to improve the survival rate of patients with colon cancer has become an important topic for scientists at home and abroad. At present, the clinical treatment of colon cancer is mainly based on surgery, but in order to enhance the therapeutic effect, it is often necessary to use traditional Chinese medicine as an adjuvant treatment in order to achieve a better therapeutic eff...
