Sirtuins are NAD(+)-dependent deac(et)ylases with different subcellular localization. The sirtuins' family is composed of seven members, named SIRT-1 to SIRT-7. Their substrates include histones and also an increasing number of different proteins. Sirtuins regulate a wide range of different processes, ranging from transcription to metabolism to...

: Sirtuin 6 (SIRT6) has a critical role in cutaneous Squamous Cell Carcinoma (cSCC): SIRT6 silencing in skin SCC cells has pro-differentiating effects and SIRT6 deletion abrogated DMBA-TPA-induced skin tumorigenesis in mice. On the other hand, SIRT6 acts as tumor suppressor in SCC by enhancing glycolysis in tumor propagating cells. Herein,...

Chronic stress induces skeletal muscle atrophy via upregulation of glucocorticoid levels. Here, the authors show that SIRT6 transcriptionally regulates glucocorticoid-induced muscle atrophy by modulating IGF/PI3K/AKT signalling.Chronic activation of stress hormones such as glucocorticoids leads to skeletal muscle wasting in mammals. However,...
