It is well known that obesity is a multifactorial condition that is the result of complex integration between many gene expressions and dietary factors. Obesity alone or in conjunction with other chronic diseases such as diabetes and insulin resistance causes many health problems and is considered a major risk factor for developing non-alcoholic steatohepatitis (NASH) and cirrhosis. In this study, we aimed to understand the molecular mechanisms underlying early hepatic changes in the pathophysiology of high-fat diet (HFD)-induced abdominal obesity in rats. Hepatic protein profiles of normal diet and HFD-induced obesity for 24 weeks were analysed using two-dimensional differential gel electrophoresis (DIGE) and protein identification by MS. Fifty-two proteins were identified by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF), and computer-assisted DIGE image software analysis showed that eighteen major proteins were significantly differentially expressed between comparable groups, with 2\u00b70\u20134\u00b70-fold change\/more (<jats:italic>P<\/jats:italic> &lt; 0\u00b701). These proteins are regulated in response to a HFD, and differentially expressed proteins are involved in key metabolic pathways such as lipid metabolism, energy metabolism, detoxification, urea cycle and hepatic Ca homoeostasis. In addition, Western blot and immunohistochemistry of liver-specific arginase-1 (Arg-1) showed significant increased expression in the liver of high-fat-fed rats (<jats:italic>P<\/jats:italic> &lt; 0\u00b701). Further, Arg-1 expression was correlated with NASH patients with obesity-related fibrosis (F0\u2013F4). It is concluded that high-fat content may affect changes in liver pathways and may be a therapeutic target for obesity-related liver disease. Arg-1 expressions may be a potential pathological marker for assessing the progression of the disease.<\/jats:p>","DOI":"10.1017\/s0007114523002453","type":"journal-article","created":{"date-parts":[[2023,10,27]],"date-time":"2023-10-27T09:00:59Z","timestamp":1698397259000},"page":"773-785","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":2,"title":["Early hepatic proteomic signatures reveal metabolic changes in high-fat-induced obesity in rats"],"prefix":"10.1017","volume":"131","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5759-1775","authenticated-orcid":false,"given":"Abhishak C.","family":"Gupta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adil","family":"Bhat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaswinder S.","family":"Maras","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2023,10,27]]},"reference":[{"key":"S0007114523002453_ref35","doi-asserted-by":"publisher","DOI":"10.1007\/s12192-008-0073-x"},{"key":"S0007114523002453_ref15","doi-asserted-by":"publisher","DOI":"10.1038\/nprot.2006.256"},{"key":"S0007114523002453_ref16","doi-asserted-by":"publisher","DOI":"10.1038\/srep00081"},{"key":"S0007114523002453_ref23","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1522-2683(19991201)20:18<3551::AID-ELPS3551>3.0.CO;2-2"},{"key":"S0007114523002453_ref33","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2022.09.020"},{"key":"S0007114523002453_ref38","doi-asserted-by":"publisher","DOI":"10.1002\/hep.20838"},{"key":"S0007114523002453_ref44","doi-asserted-by":"publisher","DOI":"10.4196\/kjpp.2017.21.3.317"},{"key":"S0007114523002453_ref21","first-page":"1431","article-title":"Fast and sensitive colloidal coomassie G-250 staining for proteins in polyacrylamide gels","volume":"30","author":"Dyballa","year":"2009","journal-title":"J Vis Exp"},{"key":"S0007114523002453_ref49","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2019.02893"},{"key":"S0007114523002453_ref50","doi-asserted-by":"publisher","DOI":"10.1002\/cncy.21184"},{"key":"S0007114523002453_ref28","doi-asserted-by":"publisher","DOI":"10.1016\/j.molmet.2016.10.001"},{"key":"S0007114523002453_ref53","doi-asserted-by":"publisher","DOI":"10.1038\/nrneurol.2014.207"},{"key":"S0007114523002453_ref3","doi-asserted-by":"publisher","DOI":"10.1038\/nature05482"},{"key":"S0007114523002453_ref4","first-page":"575","article-title":"Peroxisome proliferators-activated receptor \u03b32 Pro12Ala variant is associated with body mass index in non-alcoholic fatty liver disease patients","volume":"1","author":"Gupta","year":"2010","journal-title":"Hepatol Int"},{"key":"S0007114523002453_ref47","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2018.06.023"},{"key":"S0007114523002453_ref8","first-page":"9","article-title":"Sex and species differences in the development of diet-induced obesity and metabolic disturbances in rodents","volume":"17","author":"Maric","year":"2022","journal-title":"Front Nutr"},{"key":"S0007114523002453_ref31","doi-asserted-by":"publisher","DOI":"10.1293\/tox.2018-0045"},{"key":"S0007114523002453_ref45","doi-asserted-by":"publisher","DOI":"10.1007\/s00535-009-0154-3"},{"key":"S0007114523002453_ref40","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbrc.2016.06.080"},{"key":"S0007114523002453_ref37","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2020.8700"},{"key":"S0007114523002453_ref52","doi-asserted-by":"publisher","DOI":"10.1002\/hep4.1438"},{"key":"S0007114523002453_ref11","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmet.2008.03.014"},{"key":"S0007114523002453_ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmet.2015.06.008"},{"key":"S0007114523002453_ref29","doi-asserted-by":"publisher","DOI":"10.3727\/105221617X15093707969658"},{"key":"S0007114523002453_ref19","doi-asserted-by":"publisher","DOI":"10.1016\/0003-2697(76)90527-3"},{"key":"S0007114523002453_ref34","first-page":"1977","article-title":"Identification of aldo-keto reductase family 1 member B10 in human hepatocellular carcinoma","volume":"44","author":"Kuno","year":"2014","journal-title":"Int J Oncol"},{"key":"S0007114523002453_ref43","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhep.2018.06.023"},{"key":"S0007114523002453_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.bbadis.2014.02.012"},{"key":"S0007114523002453_ref30","doi-asserted-by":"publisher","DOI":"10.3390\/molecules27030858"},{"key":"S0007114523002453_ref10","doi-asserted-by":"publisher","DOI":"10.1172\/JCI119171"},{"volume-title":"Electrophoretic Separation of Proteins.
