Transient receptor potential melastatin 4 contributes to early-stage endothelial injury induced by arsenic trioxide.

Background/aims: To investigate the effect of Arsenic Trioxide (ATO) on endothelial cells injury and explore the role of transient receptor potential melastatin 4 channel (TRPM4) in ATO-induced endothelial injury.

Methods: qRT-PCR was used to examine the mRNA expression of TRPM4 in human umbilical vein endothelial cells (HUVECs). The protein levels were measured by Western blot and immunostaining.

Transforming Growth Factor-β Receptor III is a Potential Regulator of Ischemia-Induced Cardiomyocyte Apoptosis.

Background: Myocardial infarction (MI) is often accompanied by cardiomyocyte apoptosis, which decreases heart function and leads to an increased risk of heart failure. The aim of this study was to examine the effects of transforming growth factor-β receptor III (TGFβR3) on cardiomyocyte apoptosis during MI.

Methods And Results: An MI mouse model was established by left anterior descending coronary artery ligation.
