Resumo
Renal cell carcinoma (RCC) represents approximately 2‐3 % of human malignancies. Despite all new
therapeutic advances, almost all patients develop resistance to treatment and cure is rarely seen. The
transcription factor KB (NFKB) comprises a family of transcription factors which has been associated
with apoptosis resistance and progression of RCC. In this study, shRNA plasmid vector against NFKB1 gene was stably transduced into the Renca murine RCC cell line. Knockdown of NFKB1 was confirmed by
quantitative real time PCR, Western blot and immunofluorescence analysis. The biological effects of
decreased NFKB1 protein levels were evaluated, in vitro, by cell cycle and doubling time analysis and, in
vivo, by tumor growth, cell proliferation (PCNA staining) and apoptosis (Caspase‐3 staining) and necrosis
(morphometry). The results revealed that NFKB1 knockdown efficiently inhibited the growth of RencashRNA
cells in culture, induced cell cycle arrest at the G2/M phase and led to a significant decrease of
the doubling‐time. Moreover, NFKB1 shRNA vector suppressed tumor growth, enhanced apoptosis and
necrosis compared with a wild type and mock control groups. In conclusion, our results suggest that
specific silencing of NFKB is a potential therapeutic strategy for the treatment of RCC. This research was
