Higher epigenetic diversity could alleviate the loss of genetic diversity
Genetic diversity is generally considered the chief determinant of evolutionary change, but epigenetic diversity is now recognized as another layer of heritable variation with potential adaptive...
Changes in melanocyte RNA and DNA methylation favor pheomelanin synthesis and may avoid systemic oxidative stress after dietary cysteine supplementation in birds
Cysteine plays essential biological roles, but excessive amounts produce cellular oxidative stress. Cysteine metabolism is mainly mediated by the enzymes cysteine dioxygenase and ?-glutamylcysteine...
