CDK6 and bladder transitional cell carcinoma: Narrowing to cases with CDK6 scores higher than 240, there was a strong correlation between IHC and RNA-sequencing methods (R = 0.94, p = 0.01 by IHC scores vs. gene counts; R = 0.9, p = 0.01 by IHC scores vs. FPKM value; Figures 3B, D), suggesting that high CDK6 H-score level is consistent with high CDK6 mRNA levels in BLCA cases.
