In the present study, the search for polymorphisms within the ovine SIRT1 and SIRT2 loci as well as association analyses between SNPs and growth-related traits were performed in Tibetan sheep. To determine the expression pattern of SIRT1 and SIRT2 genes in Tibetan sheep, the quantitative real-time polymerase chain reaction (qPCR) analysis revealed that those two genes were widely expressed in diverse tissues. Expression of SIRT1 was less in abomasum of lamb, whereas it was greater in duodenum within adult stage. In the case of SIRT2, the greatest expression was observed in reticulum (lamb) and in muscle (adult), whereas the least expression was in liver for lamb and in kidney for adult animals. The association analysis demonstrated that g.3148 C &gt; T polymorphism of SIRT1 affected heart girth (p = 0.002). The g.8074 T &gt; A SNP of SIRT2 had a significant correlation with body weight (p = 0.011) and body length (p = 0.008). These findings suggested that the SIRT1 and SIRT2 polymorphism was involved in growth-related traits in Tibetan sheep, which may be considered to be genetic markers for improving the growth traits of Tibetan sheep.<\/jats:p>","DOI":"10.3390\/ani10081362","type":"journal-article","created":{"date-parts":[[2020,8,6]],"date-time":"2020-08-06T09:41:21Z","timestamp":1596706881000},"page":"1362","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Association between Single Nucleotide Polymorphisms in SIRT1 and SIRT2 Loci and Growth in Tibetan Sheep"],"prefix":"10.3390","volume":"10","author":[{"given":"Lin-sheng","family":"Gui","sequence":"first","affiliation":[{"name":"State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xining 810016, Qinghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0961-1911","authenticated-orcid":false,"given":"Sayed Haidar Abbas","family":"Raza","sequence":"additional","affiliation":[{"name":"National Beef Cattle Improvement Center, Northwest A&amp;F University, Yangling 712100, Shaanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zhou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xining 810016, Qinghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Garcia","sequence":"additional","affiliation":[{"name":"School of Animal Dairy and Veterinary Sciences, Utah State University, Logan, UT 84322, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8306-0011","authenticated-orcid":false,"given":"Ayman Hassan","family":"Abd El-Aziz","sequence":"additional","affiliation":[{"name":"Animal Husbandry and Animal Wealth Development Department, Faculty of Veterinary Medicine, Damanhour University, Damanhour 22511, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dawei","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Agriculture, Ningxia University, Yinchuan 750021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengzhen","family":"Hou","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xining 810016, Qinghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianlei","family":"Jia","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xining 810016, Qinghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyou","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xining 810016, Qinghai, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.1038\/nrm3293","article-title":"Sirtuins as regulators of metabolism and healthspan","volume":"13","author":"Houtkooper","year":"2012","journal-title":"Nat.
