Mir-15A Reconstitution in Prostate Cancer Cell Line Suppresses Cancer Progression Through Down Regulation of MYB and Androgen Receptor Upregulation

Prostate cancer is one of the most common malignancies and the second leading cause of death from cancer in men. MicroRNAs are noncoding RNAs that have a role of post-transcriptional regulators. In this study we investigated how the tumour suppressor miR-15a modulates main transcription factors like...

MicroRNAs are noncoding RNAs that have a role of post-transcriptional regulators. In this study we investigated how the tumour suppressor miR-15a modulates main transcription factors like cMYB and AR in androgen sensitive prostate cancer cell line LNCaP. The miR-15a inhibitor, mimic, and their negative controls were transfected into LNCaP cells. Real-time PCR analysis was performed in order to estimate the transcript levels of cMYB and AR. Flow cytometry analysis was performed to measure the protein levels of cMYB and AR. A Cell migration assay was done for cells transfected with miR-15a inhibitor and mimic. We found that cMYB is down-regulated and AR is up-regulated by miR-15a on the transcriptional and protein levels. By reconstituting miR-15a, we found that its down regulation in prostate cancer contributes to cMYB-induced cancer progression and reduced androgen receptivity. The ability of miR-15a to suppress cancer cell viability and migration is a very important phenomenon for understanding cancer heterogeneity in regard to adapted therapeutic approach development.Todorova K.Hayrabedyan S.Sciendoarticleprostate cancermicrornaarcmybMedicineRENActa Medica Bulgarica, Vol 42, Iss 1, Pp 18-22 (2015)
