Thus, an efficient glutathione-based lipid redox system is essential for maintaining cellular functions. However, the relationship between disruption of the redox system during ischemia-reperfusion (IR), oxidized lipid production, and consequent cell death (ferroptosis) remains unclear

BACKGROUND Obesity is a well-established risk factor for both adverse pregnancy outcomes (APOs) and cardiovascular disease (CVD). However, it is not known whether APOs are mediators or markers of the obesity-CVD relationship. This study examined the association between body mass index, APOs, and postpartum CVD risk factors. METHODS The sample included adults from the nuMoM2b (Nulliparous Pregnancy

Myocardial Recovery in Recent Onset Dilated Cardiomyopathy: Role of CDCP1 and Cardiac Fibrosis. Circ. Res. (IF 20.1) Pub Date : 2023-10-06 Duan Liu,Min Wang,Vishakantha Murthy,Dennis M McNamara,Thanh Thanh L Nguyen,Trudy J Philips,Hridyanshu Vyas,Huanyao Gao,Jyotan Sahni,Randall C Starling,Leslie T Cooper,Michelle K Skime,Anthony Batzler,Gregory D Jenkins,Simona Barlera,Silvana Pileggi,Luisa Mestroni,Marco Merlo,Gianfranco Sinagra,Florence Pinet,Jan Krejčí,Anna Chaloupka,Jordan D Miller,Pascal de Groote,Daniel J Tschumperlin,Richard M
BACKGROUND Dilated cardiomyopathy (DCM) is a major cause of heart failure and carries a high mortality rate. Myocardial recovery in DCM-related heart failure patients is highly variable, with some patients having little or no response to standard drug therapy. A genome-wide association study may agnostically identify biomarkers and provide novel insight into the biology of myocardial recovery in DCM

TMEM215 Prevents Endothelial Cell Apoptosis in Vessel Regression by Blunting BIK-Regulated ER-to-Mitochondrial Ca Influx. Circ. Res. (IF 20.1) Pub Date : 2023-09-26 Peiran Zhang,Xianchun Yan,Xiaoyan Zhang,Yuan Liu,Xingxing Feng,Ziyan Yang,Jiayulin Zhang,Xinyuan Xu,Qijun Zheng,Liang Liang,Hua Han
BACKGROUND In developmental and pathological tissues, nascent vessel networks generated by angiogenesis require further pruning/regression to delete nonfunctional endothelial cells (ECs) by apoptosis and migration. Mechanisms underlying EC apoptosis during vessel pruning remain elusive. TMEM215 (transmembrane protein 215) is an endoplasmic reticulum-located, 2-pass transmembrane protein. We have previously
