The 40 oncogenes were mostly enriched with positive regulation of gene expression, macromolecule biosynthetic process, cell death and hemopoiesis, whereas the 34 TSGs were mostly involved in metabolic process and negative regulation of cell death, such as BCL2L1, an apoptosis suppressor gene which is found in most of the leukemia types, and, opposite to the oncogene results - negative regulation of cell death. This evidence concerns the gene BCL2L1 and leukemia.
