BCL2L1 and cancer: Other genes such as the pro-apoptotic gene BAX, as well as the tumor suppressor TP53, showed strong statistically significant positive correlations in most cancer types, while the antiapoptotic BCL2L1 and BCL2 genes presented a more intricate pattern, exhibiting both positive and negative correlations with PEBP1/STK11 co-expression on a cancer type dependent manner.
