How Aging Affects Heart Scarring and the Role of Sirtuin Proteins

Updated

Abstract

Sirtuins are involved in regulating myocardial fibrosis, a key feature of heart failure.

  • SIRT1, SIRT3, and SIRT6 may inhibit fibroblast activation and reduce oxidative and inflammatory damage.
  • SIRT4 could promote fibrosis depending on the specific context.
  • The review discusses the role of non-coding RNAs and histone modifications in regulating sirtuin expression.
  • There is a complex feedback between sirtuins and processes like mitochondrial balance and endothelial-to-mesenchymal transition.
  • Sirtuins are positioned as potential therapeutic targets for cardiac fibrosis due to their dual roles.
