The role of selenium-mediated redox signaling by selenophosphate synthetase 1 (SEPHS1) in hESCs

Selenium (Se) plays a vital role in reactive oxygen species (ROS) homeostasis and redox regulation in intracellular signaling via selenocysteine (Sec), known as the 21st proteinogenic amino acid, but its specific biological functions in development and disease remain undiscovered. In this study, we explored the role of selenophosphate synthetase 1 (SEPHS1) in the pluripotency maintenance and reprogramming. We found that high level of SEPHS1 is...
