| Popis: | The potential role of microRNAs (miRNA or MIR) as therapeutic molecules has moved them from basic research to the field of cancer therapy. High expression of miR-93 and low expression of miR-34a have previously been indicated in prostate cancer (PC), which is the second leading cause of cancer-related death in men. Androgen receptor (AR) and prostate-specific antigen (PSA) play key roles in the initiation and progression of this cancer. Therefore, this study aimed to investigate the effects of the transfection and co-transfection of miR-34a mimic and miR-93 inhibitor with or without epigallocatechin-3-gallate (EGCG) on prostate cancer cell line and also to evaluate their effects on the expression of AR, PSA. Human lymph node carcinoma of the prostate (LNCaP) cells were treated with miR-34a mimic or/and miR-93 inhibitor with or without EGCG. Gene or protein expressions were assessed by real-time PCR or western blotting of lysates. The transfection with miR-34a mimics significantly reduced the mRNA expression of AR (p=0.0016), and PSA (p=0.038) compared to the control. Also, the miR-93 inhibitor led to a decrease in the mRNA expression of AR (p=0.0057) and PSA (p>0.05) compared to the control group. Furthermore, the co-transfection, along with EGCG, caused more decrease in both the AR (p |
