CDK4 and cancer: Further, the exploration of biological pathways to identify gene neighbors for BCL2L1 was conducted using the web‐version of STRING database (STRING‐DB) [23], where a k‐means clustering followed by a co‐expression analysis yielded nine closest gene‐neighbors: CDKN1A, FOXO3, MAPK1, BAX, TP53, CYCS, GADD45A, CDK4, and CASP, which are known to be co‐expressed in several pathways in cancer (Figure S2).
