Developing evidence in the literature suggests that SIRT5 may be involved in metabolic reprogramming, an emerging hallmark of cancer by which neoplastic cells reconfigure their metabolism to support the anabolic demands of rapid cell division. Sirtuin 5 (SIRT5) is one of the seven members of the nicotinamide adenine dinucleotide (NAD+)-dependent sirtuin family of lysine deacylases. It removes succinyl, malonyl, and glutaryl groups from protein targets within the mitochondrial matrix and other subcellular compartments. SIRT5’s substrates include a number of proteins integral to metabolism. Recent Advances: New work has begun to elucidate the roles of SIRT5 in glycolysis, TCA cycle, FAO, nitrogen metabolism, pentose phosphate pathway, antioxidant defense, and apoptosis.

The sirtuins are a family of proteins that comprise class III of the histone deacetylases. These NAD+-dependent proteins have been found to be intricately involved in a variety of important and skin-relevant cellular functions and processes, including aging, UV damage response, oxidative stress, and wound repair. In addition, recent research is unraveling the role of sirtuins in a variety of skin diseases, including melanoma and nonmelanoma skin cancers. In this review, we provide a discussion on the potential roles and implications of different sirtuins in skin-specific cellular processes, which may have relevance to skin health and skin diseases. Based on the available literature, the sirtuins appear to be important targets in the management of a variety of skin diseases from cosmetic (e.g., skin aging) to fatal conditions (e.g., melanoma).
