Ectopic expression of ApoL6 induces dichotomous cell death phenotype involving both apoptosis and necroptosis in various cell types. In addition, ApoL6 initiates inflammatory response that upregulates proinflammatory cytokines, such as IL-1β. In this study, we show elevated levels of ApoL6 in the sera of the majority of ST-segment myocardial infarction (STEMI) patients prior to reperfusion which is highly suggestive of the activation of apoptotic and/or necroptotic pathways in ruptured plaque. Thus, ApoL6 could serve as a biomarker specific for inflammatory apoptotic and/or necroptotic activity in STEMI, as well as other diseases.
