From: Down-regulation of PKCζ in renal cell carcinoma and its clinicopathological implications
Down-regulation of PKCζ showed the higher chemoresistance in RCC cell lines. (A) PKCζ protein expression in HK-2 and 4 RCC cell lines by Western blotting. α-tubulin was used as an internal control. (B) The intensity of PKCζ protein in figure 4(A) was examined by densitometer analysis. Fold changes were normalized against the expression of PKCζ protein in HK-2 cells. Chemosensivity of HK-2, 786-O and ACHN cells to (C) cisplatin and (D) paclitaxel were examined by MTT assay, respectively.
