It is worth noting that certain subtypes of leukemia are caused by the formation of abnormal oncogenic proteins (e.g., PML-RARα, BCR-ABL, BET) [126,127], while the emergence of several small molecules, such as arsenic trioxide (As2O3) and imatinib, successfully cures such types of leukemia. This evidence concerns the gene PROS1 and leukemia.
