Abstract

The invention belongs to the field of medicines or health products, and particularly relates to the use of catechin and epicatechin compounds in the preparation of drugs for up-regulating the expression level of microRNA-150. As found by researches, catechin, catechin gallate, gallocatechin, (-)-gallocatechin gallate, epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallatecan up-regulate the expression level of the microRNA-150, and can be used for treating myocardial hypertrophy, hypertension, ischemic cardiomyopathy, myocardial infarction, arrhythmia, cancer or sepsis.

Description

technical field [0001] The invention belongs to the field of medicines or health care products, and in particular relates to the use of catechins and epicatechins in the preparation of medicines for up-regulating the expression level of MicroRNA-150. Background technique [0002] MicroRNA is a kind of non-coding single-stranded small molecule RNA with a length of about 19-23 nucleotides. Mature MicroRNA can complement and pair with target mRNA molecules to induce target mRNA degradation or translation inhibition, thereby exerting the function of regulating gene expression. Studies in recent years have shown that MicroRNA is closely related to the occurrence and development of tumors, cardiovascular diseases, diabetes, human genetic diseases and even major diseases of the nervous system. MicroRNA is tissue-specific. MicroRNA-150 is mainly expressed in the spleen, thoracic cavity, abdominal cavity, and myocardium. It participates in the occurrence of the immune system and hema...
