Substance use disorder is a major global health and economic burden. Therefore, the search for predisposing factors for the development of this disease can contribute to reducing the health and social damage associated with addiction. In this study, we focused on the impact of the maternal diet on changes in melanocortin-4 (MC-4) receptors as well as on behavioral changes related to cocaine addiction. Rat dams consumed a high-fat diet (HFD), high-sugar diet (HSD, rich in sucrose), or mixed diet (MD) during pregnancy and lactation. Using an intravenous cocaine self-administration model, the susceptibility of female offspring to cocaine reward and cocaine-seeking propensities was evaluated. In addition, the level of MC-4 receptors in the rat brain structures related to cocaine reward and relapse was assessed. Modified maternal diets did not affect cocaine self-administration in offspring. However, the maternal HSD enhanced cocaine-seeking behavior in female offspring. In addition, we observed that the maternal HSD and MD led to increased expression of MC-4 receptors in the nucleus accumbens, while increased MC-4 receptor levels in the dorsal striatum were observed after exposure to the maternal HSD and HFD. Taken together, it can be concluded that a maternal HSD is an important factor that triggers cocaine-seeking behavior in female offspring and the expression of MC-4 receptors.<\/jats:p>","DOI":"10.3390\/nu12051462","type":"journal-article","created":{"date-parts":[[2020,5,20]],"date-time":"2020-05-20T02:48:24Z","timestamp":1589942904000},"page":"1462","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Maternal Diet Influences the Reinstatement of Cocaine-Seeking Behavior and the Expression of Melanocortin-4 Receptors in Female Offspring of Rats"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9376-0564","authenticated-orcid":false,"given":"Dawid","family":"Gawli\u0144ski","sequence":"first","affiliation":[{"name":"Maj Institute of Pharmacology Polish Academy of Sciences, Department of Drug Addiction Pharmacology, Sm\u0119tna Street 12, 31-343 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7015-154X","authenticated-orcid":false,"given":"Kinga","family":"Gawli\u0144ska","sequence":"additional","affiliation":[{"name":"Maj Institute of Pharmacology Polish Academy of Sciences, Department of Drug Addiction Pharmacology, Sm\u0119tna Street 12, 31-343 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6646-6140","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Frankowska","sequence":"additional","affiliation":[{"name":"Maj Institute of Pharmacology Polish Academy of Sciences, Department of Drug Addiction Pharmacology, Sm\u0119tna Street 12, 31-343 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u0142gorzata","family":"Filip","sequence":"additional","affiliation":[{"name":"Maj Institute of Pharmacology Polish Academy of Sciences, Department of Drug Addiction Pharmacology, Sm\u0119tna Street 12, 31-343 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"987","DOI":"10.1016\/S2215-0366(18)30337-7","article-title":"The global burden of disease attributable to alcohol and drug use in 195 countries and territories, 1990\u20132016: A systematic analysis for the Global Burden of Disease Study 2016","volume":"5","author":"Degenhardt","year":"2018","journal-title":"Lancet Psychiatry"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"159","DOI":"10.2147\/RMHP.S131834","article-title":"Violence within mental health services: How to enhance risk management","volume":"11","author":"Wrigley","year":"2018","journal-title":"Risk Manag.
