Analysis of matched Bcl-xL transcript abundance (by Agilent microarray), and protein level, (by Reverse Phase Protein Array (RPPA)) from 102 CRC tumor samples within The Cancer Genome Atlas (TCGA) indicated a significant correlation between both methodologies (p = 0.001; Supplementary Figure 5B), supporting protein-based assessment as an appropriate methodology to validate our data in an independent cohort. This evidence concerns the gene BCL2L1 and colorectal carcinoma.
