Description
Preclinical study of CDK4/6 inhibitor PD-0332991 in 28 renal carcinoma cell lines (25 malignant RCC and three non-malignant, transformed cell lines derived from kidney epithelium). Both p15 and p16 loss (CGH) were tested for association with response to PD-0332991 using Fisher's exact test. Cell lines with p16 and p15 losses were significantly more likely to be classified as responders (defined by pharmacokinetic data-based concentration of <=400nM) to PD-0332991 (p=0.027, relative risk (RR)=2.06 and p=0.047, RR=1.71, respectively). Four cell lines had homozygous deletions of CDKN2A but not CDKN2B, and three of these lines were classified as being sensitive to PD-0332991. There were no cell lines with only CDKN2B deletion.
