Problems solved by technology

[0008]Although it is known in the art that certain microRNAs have certain correlations with tumors, there are many kinds of miRNAs known in the art with different functions. It is difficult to screen out specific miRNAs that are related to tumors and can be used as pathogenesis, treatment options and prognosis
At present, there is no report on the correlation between miR-143 and B7-H4 gene in this field

Abstract

The invention discloses MicroRNA (micro ribonucleic acid) for regulating gene expression of B7-H4 (a molecule of the B7 family). The microRNA is nucleic acid, functional segment or variant including a sequence of 5'-UGAGAUGAAGCACUGUAGCUC-3'. The microRNA is miR-143. Performed in-vitro biological function tests show that hsa-miR-143 is capable of inhibiting molecular expression of the B7-H4 by bonding with 3'-UTR (untranslated regions) of the B7-H4 gene, and antitumor effect is achieved by regulating a signal path of the B7-H4 and / or expression and functions of the miR-143.

Description

technical field [0001] The invention belongs to the field of biotechnology and medical technology, specifically, the invention relates to the technical field of gene expression regulation, in particular to a kind of microRNA used to regulate the expression of B7-H4 gene. Background technique [0002] Tumor has been a serious threat to human health and life, and traditional treatment methods are not satisfactory. Immunotherapy achieves the purpose of treating tumors by improving the immunogenicity of tumors and inducing the body to produce specific anti-tumor immune responses. It is a biological treatment method that changes from passive to active. Cellular immunity mediated by T cells is the main form of anti-tumor immunity. Through the specific recognition of tumor antigens, the body activates T cells and produces corresponding immune killing effects. [0003] It has been demonstrated that the efficient activation and function mediation of T cells requires the synergy of d...
