AR and renal cell carcinoma: The results (after 5 weeks) revealed that addition of AR in OSRC-2 cells increased growth and tumor weight in athymic nude mice compared to Vec-AR OSRC-2 cells, while stable expression of miR-145 in the OE-AR OSRC-2 cells could partially reverse the positive impact of AR and decreased the RCC tumor growth and tumor weight (Figure 6B-6C).
