The RT-qPCR results showed The fold change in mRNA expression of anti-apoptotic markers Bcl2 and Bcl-xL was significantly increased in BE (p = 0.04 and p = 0.13) and EAC tissues (p = 0.05 and p = 0.10) compared to the normal esophageal tissues while there were no significant differences for Bcl2 and BcL-xL between BE and EAC (Fig. 2 panel A). This evidence concerns the gene BCL2 and Barrett esophagus.
