D-serine suppresses one-carbon metabolism by competing with mitochondrial L-serine transport

This study reveals that D-serine suppresses one-carbon metabolism by competing with mitochondrial L-serine transport, thereby inhibiting the proliferation of immature neural cells and suggesting a developmental shift in serine enantiomer metabolism that aligns with the functional transition of the maturing nervous system.

Caloric Restriction Promotes Ischemia/Reperfusion Cardioprotection Through Increased Mitochondrial Na+/Ca2+ Exchange

Caloric restriction protects the heart against ischemia/reperfusion injury by enhancing CGP-sensitive, Na+-dependent mitochondrial Ca2+ efflux via upregulation of NCLX and TMEM65, which prevents mitochondrial Ca2+ overload and redox imbalance.
