Breast cancer (BC) is one of the cancer types known to be associated with alterations in the lipid metabolism and overexpression of enzymes involved in this metabolism. It has been demonstrated that inhibition of the activity of certain enzymes, such as that of phospholipase A2 in BC cell lines sensitizes these cells and decreases the IC50 values for forthcoming therapy with traditional drugs, such as doxorubicin and tamoxifen. Moreover, other phospholipases, such as phospholipase C and D, are involved in intracellular signal transduction, which emphasizes their importance in cancer development. Finally, BC is assumed to be dependent on the diet and the composition of lipids in nutrients. Despite their importance, analytical approaches that can associate the activity of phospholipases with changes in the lipid composition and distribution in cancer tissues are not yet standardized. In this review, an overview of various analytical platforms that are applied on the study of lipids and phospholipase activity in BC tissues will be given, as well as their association with cancer diagnosis and tumor progression. The methods that are applied to tissues obtained from the BC patients will be emphasized and critically evaluated, regarding their applicability in oncology.<\/jats:p>","DOI":"10.3390\/metabo11010032","type":"journal-article","created":{"date-parts":[[2021,1,4]],"date-time":"2021-01-04T21:58:36Z","timestamp":1609797516000},"page":"32","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Analytical Platforms for the Determination of Phospholipid Turnover in Breast Cancer Tissue: Role of Phospholipase Activity in Breast Cancer Development"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7223-1022","authenticated-orcid":false,"given":"Rosa","family":"Perestrelo","sequence":"first","affiliation":[{"name":"CQM\u2014Centro de Qu\u00edmica da Madeira, Universidade da Madeira, Campus Universit\u00e1rio da Penteada, 9020-105 Funchal, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marijana","family":"Petkovic","sequence":"additional","affiliation":[{"name":"CQM\u2014Centro de Qu\u00edmica da Madeira, Universidade da Madeira, Campus Universit\u00e1rio da Penteada, 9020-105 Funchal, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3018-3165","authenticated-orcid":false,"given":"Catarina Lu\u00eds","family":"Silva","sequence":"additional","affiliation":[{"name":"CQM\u2014Centro de Qu\u00edmica da Madeira, Universidade da Madeira, Campus Universit\u00e1rio da Penteada, 9020-105 Funchal, Portugal"},{"name":"Faculdade de Ci\u00eancias da Vida, Unidade de Ci\u00eancias M\u00e9dicas, Universidade da Madeira, Campus Universit\u00e1rio da Penteada, 9020-105 Funchal, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"637","DOI":"10.1016\/j.bbalip.2011.06.009","article-title":"Lipid classification, structures and tools","volume":"1811","author":"Fahy","year":"2011","journal-title":"Biochim.
