Abstract—

The present study investigated Punica granatum extract (PGE) as potential proliferation inhibitory agent for bladder cancer cells and elucidated the possible mechanism. PGE reduced viabilities of HT-1197 and RT4 cells in concentration-based manner at 72 h. Colony forming potential of HT-1197 and RT4 cells was also significantly (p < 0.05) inhibited on exposure to 2 and 12 mg/mL PGE. Exposure to 12 mg/mL PGE for 72 h significantly (p < 0.05) decreased miR‑10b expression and suppressed migration potential of HT-1197 and RT4 cells. In PGE exposed HT-1197 and RT4 cells, invasiveness was reduced to 30.25 and 33.47%, respectively. PGE treatment of HT-1197 and RT4 cells caused a significant (p < 0.05) elevation in HOXD10 protein and mRNA levels compared to control. The miR‑10b mimic transfection in HT-1197 and RT4 cells reversed inhibitory effect of PGE on cell viability. Thus, PGE exhibited cytotoxicity and anti-invasive effect on HT-1197 and RT4 cells through targeting miR‑10b and up-regulation of HOXD10 expression. Thus, PGE may be developed as therapeutic agent for treatment of bladder cancer.
