Sirtuins (silent information regulators, sirts) via modification of histones, as well as transcription factors and co-regulators, control expression of other genes, particularly those involved in the organism response to stress. Detection of sirtuin expression in adipocytes initiated interest in their role in adipose tissue development and metabolism. This chapter presents how sirtuins control the critical steps of preadipocytes’ differentiation and proliferation, as well as the process of adipose tissue browning. Moreover, it shows in vitro and in vivo data proving that sirtuins are involved in the regulation of lipogenesis, lipolysis, and secretory activity of adipose tissue. Due to all these reasons, sirtuins may constitute potential targets in the treatment of obesity and related complications.
