Figure 1 depicts examples of low and intensive (high) staining results for caspase-8, CDK9 and pCDK9. The weighted scores (WS) of the expression of caspase-8 and CDK9 revealed a significant correlation with pCDK9 signals in the corresponding tumor tissues (p = 0.05 and p = 0.01). This evidence concerns the gene CASP8 and neoplasm.
