Downregulation of hsa_circ_0006620 inhibits the malignant progression of prostate cancer by regulation of the miR-502-3p/HK2 axis mediated by aerobic glycolysis.
Circular RNAs (circRNA) are a class of covalently-closed, single-stranded RNAs that have been implicated in cancer progression due to their regulation of metabolism. However, the roles of circRNA in prostate cancer remain largely unknown. In this study, fluorescence in situ hybridization and RT-qPCR were used to investigate hsa_circ_0006620 expressions in both prostate cancer cells and tissues, after high-throughput sequencing. The luciferase reporter assay was used to identify hsa_circ_0006620 downstream targets. Transwell migration assays, 5-ethynyl-20-deoxyuridine assays, and Cell Counting Kit-8assays were used to investigate both proliferation and migration. In vivo tumorigenesis and metastasis assays were performed to investigate the role of hsa_circ_0006620 in prostate cancer. The results showed that hsa_circ_0006620 expression increased in prostate cancer cells and tissues. Hsa_circ_0006620 downregulation inhibited prostate cancer cell proliferation as well as in vivo and in vitro migrations. The luciferase results validated that miR-502-3p and hexokinase 2 (HK2) were hsa_circ_0006620 downstream targets. HK2 overexpression or miR-502-3p inhibition reversed prostate cancer cell migration after hsa_circ_0006620 silencing. The study also found that overexpression of HK2 or inhibition of prostate cancer reversed aerobic glycolysis after hsa_circ_0006620 silencing. In summary, the results showed thathsa_circ_0006620 downregulation inhibited prostate cancerby regulation of the miR-502-3p/HK2 axis mediated by aerobic glycolysis.
期刊介绍:
The Journal''s scope encompasses all aspects of metastasis research, whether laboratory-based, experimental or clinical and therapeutic. It covers such areas as molecular biology, pharmacology, tumor biology, and clinical cancer treatment (with all its subdivisions of surgery, chemotherapy and radio-therapy as well as pathology and epidemiology) insofar as these disciplines are concerned with the Journal''s core subject of metastasis formation, prevention and treatment.
