In obesity, the size and number of adipocytes and adipokine secretion increases. In T1DM, a loss of adipose tissue suggests changes in the metabolic activity of this tissue. A significant challenge is to find alternative noninvasive methods to evaluate molecular changes in adipose tissue related to obesity and T1DM. Recently, Raman spectroscopy and chemometrics techniques have emerged as a tool for biological tissue analysis. In this work, we propose the use of Raman spectroscopy to characterize spectral differences in adipose tissue from different rat groups (control, obese, and T1DM). The Raman spectra were analyzed using direct band analysis, ratiometric analysis, and chemometric methods (principal component analysis (PCA) and support vector machines (SVMs)). We found that the Raman spectra of obese rats showed significant spectral differences compared to control and diabetic groups related to fatty acids Raman bands. Also, the obese group has a significant decrease in the degree of unsaturation of lipids. The PCA\u2013SVM models showed classification performance ranging from 71.43% to 71.79% accuracy for brown and white adipose tissue samples, respectively. In conclusion, the results demonstrate that Raman spectroscopy can be used as a nondestructive method to assess adipose tissue according to a metabolic condition.<\/jats:p>","DOI":"10.1177\/0003702821990357","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T10:46:25Z","timestamp":1611053185000},"page":"1189-1197","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Raman Spectroscopy for Adipose Tissue Assessment in Rat Models of Obesity and Type 1 Diabetes"],"prefix":"10.1177","volume":"75","author":[{"given":"Guadalupe","family":"Donju\u00e1n-Loredo","sequence":"first","affiliation":[{"name":"Facultad de Medicina, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Espinosa-Tanguma","sequence":"additional","affiliation":[{"name":"Facultad de Medicina, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0981-3262","authenticated-orcid":false,"given":"Fabiola","family":"Le\u00f3n-Bejarano","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordi A.","family":"Ram\u00edrez-El\u00edas","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Salgado-Delgado","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1346-9073","authenticated-orcid":false,"given":"Francisco J.","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n para la Innovaci\u00f3n y Aplicaci\u00f3n de la Ciencia y la Tecnolog\u00eda (CIACyT), Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edgar","family":"Guevara","sequence":"additional","affiliation":[{"name":"Coordinaci\u00f3n para la Innovaci\u00f3n y Aplicaci\u00f3n de la Ciencia y la Tecnolog\u00eda (CIACyT), Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"},{"name":"CONACYT\u2013Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5233-9581","authenticated-orcid":false,"given":"Miguel G.","family":"Ram\u00edrez-El\u00edas","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias, Universidad Aut\u00f3noma de San Luis Potos\u00ed, San Luis Potos\u00ed, M\u00e9xico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,2,1]]},"reference":[{"key":"bibr1-0003702821990357","doi-asserted-by":"publisher","DOI":"10.2337\/db12-1430"},{"key":"bibr2-0003702821990357","doi-asserted-by":"crossref","unstructured":"A.L.
