H2S to Mitigate Vascular Aging: A SIRT1 Connection

H2S is an endogenous gasotransmitter that plays an important role in physiological conditions. In this issue, Das et al. provide evidence that SIRT1-dependent angiogenesis is augmented by H2S-findings reinforced by Longchamp et al., who demonstrate that H2S-dependent angiogenesis is triggered by amino acid deprivation.
