CSN4 regulates CSN5 protein levels in prostate cancer cell lines. LNCaP and CWR-22Rv1 cells were transfected with (A) Ctrl siRNA or CSN4 siRNA or (B) Ctrl siRNA or CSN5 siRNA, and Western blotting was used to measure CSN4 and CSN5. β-Actin was used as loading control and the molecular weights of the proteins are 38 kDa (CSN5), 49 kDa (CSN4), and 42 kDa (β-actin).
