Utilizing transcriptional data derived from flow-sorted immune (n = 6), epithelial (n = 6), and fibroblast (n = 6) populations isolated from CRC primary tumor tissue (GSE3939625; Supplementary Table 3), we likewise identified elevated levels of bcl2 mRNA levels in leukocytes compared to cancer (epithelial) cells (analysis of variance [ANOVA] p = 0.006, Tukey post-hoc p = 0.005). The gene discussed is BCL2; the disease is cancer.
