Abstract

The invention discloses an application method of annular RNAcircRNF13, and particularly relates to an application of an overexpression circRNF13 preparation in preparing a preparation for reducing thedrug resistance of tongue squamous cell carcinoma cells to cis-platinum drugs. The research proves that the circRNF13 is over-expressed in the tongue squamous carcinoma drug-resistant cells, so thatthe drug resistance of the tongue squamous carcinoma cells can be apparently reversed. Therefore, the circRNF13 overexpression preparation is used for reducing the drug resistance of the tongue squamous carcinoma cells and has the profound clinical significance and important popularization and application prospect.

Description

technical field [0001] The invention belongs to the field of tumor molecular biology, and in particular relates to the application of a reagent for promoting the expression of circRNF13 in the preparation of a preparation for reducing the drug resistance of tongue squamous cell carcinoma cells to cisplatin drugs. Background technique [0002] Human Genome Project and its follow-up DNA Element Encyclopedia Project (The Encyclopedia of DNAElements Project, ENCODE) research results show that protein-coding gene sequences only account for 1-3% of the human genome sequence, while most of the human genome can be transcribed The sequence is non-coding RNA (non-coding RNA, ncRNA). Although non-coding RNA does not encode protein, it has been attracting much attention in the field of biomedical research due to its extensive involvement in the regulation of gene expression in cells. The most studied are linear ncRNA molecules, which can be divided into microRNA (microRNA, miRNA, 19-23...
