Potential role of sirtuins in livestock production

Abstract: Sirtuins are NAD+-dependent histone and protein deacetylases, which have been studied during the last decade with a focus on their role in lifespan extension and age-related diseases under normal and calorie-restricted or pathological conditions. However, sirtuins also have the ability to regulate energy homeostasis as they can sense the metabolic state of the cell through the NAD+/NADH ratio; hence, changes in the diet can modify the expression of these enzymes. Dietary manipulations are a common practice cur… Show more

“…Sirt1 expression of fatty pigs was greater than lean pigs in brain. Except Sirt1, the most extensively studied Sirtuins, the expression and function of other Sirtuins in pigs are little known (Ghinis-Hozumi et al, 2013). We also studied the expression pattern of Sirt2-7 in brain and found that the mRNA levels of Sirt2 and Sirt4 of fatty Jinhua pigs were greater, while the mRNA levels of Sirt3-7 of lean Landrace pigs were greater at the age of 180 days.…”

“…Since Sirt2 and Sirt4 also highly expressed in brain of Jinhua pigs, Sirt1, Sirt2, and Sirt4 may play critical roles in brain antioxidant capacity in pigs. Sirtuins have been proved to play an important role in the regulation of energy balance in livestock (Ghinis-Hozumi et al, 2013), however there is little research about the role of Sirtuins and antioxidant capacity in porcine brain. Our results will add new knowledge to Sirtuins' function in livestock.…”

“…Other studies in fish have related SIRTs to ammonia levels (Connon et al, 2011 ), cold exposure (Teigen et al, 2015 ), spatial learning (Rajan et al, 2015 ), changes in blood glucose (Otero-Rodiño et al, 2016 ) and adipocyte maturation during hypoxia (Ekambaram and Parasuraman, 2017 ). Nevertheless, SIRT function and regulation remain poorly studied in fish and in livestock animals in general (Ghinis-Hozumi et al, 2013 ).…”

“…Few SIRT2 variants have been reported to date for cattle, as most research has focused on rodents and human models [ 11 ]. The Qinchuan breed of cattle ( Bos taurus ) used in our research is one of the outstanding indigenous breeds in China, known for its excellent adaptability and physical features.…”
