However, recent advances in matrix-assisted laser desorption\/ionization-imaging mass spectrometry (MALDI-IMS) have minimized or eliminated many technical challenges that previously limited progress in CNS disease-based lipidomic research. MALDI-IMS can be used for lipid identification, semi-quantification, and the refined interpretation of histopathology. The present work illustrates the use of tissue micro-arrays (TMAs) for MALDI-IMS analysis of frontal lobe white matter biochemical lipidomic pathology in an experimental rat model of chronic ethanol feeding. The use of TMAs combines workload efficiency with the robustness and uniformity of data acquisition. The methods described for generating TMAs enable simultaneous comparisons of lipid profiles across multiple samples under identical conditions. With the methods described, we demonstrate significant reductions in phosphatidylinositol and increases in phosphatidylcholine in the frontal white matter of chronic ethanol-fed rats. Together with the use of a novel rapid peak alignment protocol, this approach facilitates reliable inter- and intra-group comparisons of MALDI-IMS data from experimental models and could be extended to human disease states, including using archival specimens.<\/jats:p>","DOI":"10.3390\/applbiosci2020013","type":"journal-article","created":{"date-parts":[[2023,4,5]],"date-time":"2023-04-05T02:59:43Z","timestamp":1680663583000},"page":"173-193","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Tissue Microarray Lipidomic Imaging Mass Spectrometry Method: Application to the Study of Alcohol-Related White Matter Neurodegeneration"],"prefix":"10.3390","volume":"2","author":[{"given":"Isabel","family":"Gameiro-Ros","sequence":"first","affiliation":[{"name":"Department of Pharmacology and Therapeutics, Faculty of Medicine, Autonomous University of Madrid, 28029 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lelia","family":"Noble","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Tong","sequence":"additional","affiliation":[{"name":"Department of Medicine, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emine B.","family":"Yalcin","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzanne M.","family":"de la Monte","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"},{"name":"Department of Medicine, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"},{"name":"Departments of Neurology & Neurosurgery, Rhode Island Hospital, Alpert Medical School of Brown University, Providence, RI 02903, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"603","DOI":"10.1016\/B978-0-444-62619-6.00035-5","article-title":"Neuropathology of alcoholism","volume":"125","author":"Sutherland","year":"2014","journal-title":"Handb.
