TY - JOUR T1 - SAfer cancer drug AU - Hampton T Y1 - 2013/02/06 N1 - 10.1001/jama.2013.269 JO - JAMA SP - 431 EP - 431 VL - 309 IS - 5 N2 - In cancer cells, navitoclax targets BCL-2, a prosurvival protein (a molecule that helps the cancer cell evade programmed cell death). But navitoclax also inhibits BCL-2–like 1 (BCL-XL), which is a related factor required for the survival of platelets. Therefore, treatment with the drug often causes thrombocytopenia.
