We hypothesized that in nonhuman primates (NHP), fetal programming of maternal undernutrition (MUN) persists postnatally with a dietary mismatch altering metabolic molecular systems that precede standard clinical measures. We used unbiased molecular approaches to examine response to a high fat, high-carbohydrate diet plus sugar drink (HFCS) challenge in NHP juvenile offspring of MUN pregnancies compared with controls (CON). Pregnant baboons were fed <i>ad libitum</i> (CON) or 30% calorie reduction from 0.16 gestation through lactation; weaned offspring were fed chow <i>ad libitum</i>. MUN offspring were growth restricted at birth. Liver, omental fat, and skeletal muscle gene expression, and liver glycogen, muscle mitochondria, and fat cell size were quantified. Before challenge, MUN offspring had lower body mass index (BMI) and liver glycogen, and consumed more sugar drink than CON. After HFCS challenge, MUN and CON BMIs were similar. Molecular analyses showed HFCS response differences between CON and MUN for muscle and liver, including hepatic splicing and unfolded protein response. Altered liver signaling pathways and glycogen content between MUN and CON at baseline indicate <i>in utero</i> programming persists in MUN juveniles. MUN catchup growth during consumption of HFCS suggests increased risk of obesity, diabetes, and cardiovascular disease.

When we consider Brazilian science, there has been an undeniable scientific delay generated by the pandemic, especially in areas that are not related to the coronavirus. In this context, with the aim of fostering collaboration among researchers in the field of Developmental Origins of Health and Diseases (DOHaD) and enhancing the potential for implementing public health strategies to prevent noncommunicable chronic diseases, the Brazilian Association of Developmental Origins of Health and Diseases (DOHaD Brazil) was established in 2020. In this narrative, we explore the effects of the COVID-19 pandemic in Brazil, focusing on its impacts on scientific research conducted in universities. Additionally, we underscore the significance of the DOHaD Brazil Association, particularly from the perspective of young researchers engaged in DOHaD research in Brazil.</p>","PeriodicalId":49167,"journal":{"name":"Journal of Developmental Origins of Health and Disease","volume":"15 ","pages":"e17"},"PeriodicalIF":1.8,"publicationDate":"2024-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142299413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
