Chromatin immunoprecipitation analysis further verified that increased miR-885-5p potentiated the accessibility of TIGAR promoter chromatin to transcriptional factors and facilitated TIGAR expression. miR-885-5p and its precursor both can interact mechanically with TIGAR promoter binding site and alter local chromatin structure, and subsequently upregulate TIGAR expression and participate in liver tumorigenesis.
The miR-885-5p/HK2 axis strongly links aerobic glycolysis to carcinogenesis and may become a promising therapeutic target and prognostic predictor for HCC patients.
Furthermore, integrated analysis of microRNA and mRNA expression profiles recognized a core microRNA-mRNA regulatory network and unmasked many novel genes including SCUBE3, CA6, hsa-miR-885-5p and other molecules which may play an essential role in the carcinogenesis of SACC.
Taken together, it is concluded that HSP90AA1-IT1, performs its function via regulating the development of gliomas through miR-885-5p-CDK2 signaling axis, and this has added new perspective to its role in tumorigenesis, thus providing potential therapeutic targets for glioma treatment.
