ACS Chem Neurosci 2023; 14:2775-2791. [PMID: 37471579 PMCID: PMC10401638 DOI: 10.1021/acschemneuro.3c00331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 07/05/2023] [Indexed: 07/22/2023] Open
Abstract
Anti-seizure medications used during pregnancy may have transient or long-lasting impact on the nervous system of the offspring. Therefore, there is a great need to search for alternative therapies for pregnant women suffering from seizures. One of the solutions may be the use of the ketogenic diet (KD), which has been successfully applied as a treatment of drug-resistant epilepsy in children and adults. However, the risks associated with the use of this dietary therapy during pregnancy are unknown and more investigation in this area is needed. To shed some light on this problem, we attempted to determine the potential abnormalities in brain biomolecular composition that may occur in the offspring after the prenatal exposure to KD. To achieve this, the female Wistar rats were, during pregnancy, fed with either ketogenic or standard laboratory diet, and for further studies, their male offspring at 2, 6, or 14 days of age were used. Fourier transform infrared microspectroscopy was applied for topographic and quantitative analysis of main biological macromolecules (proteins, lipids, compounds containing phosphate and carbonyl groups, and cholesterol) in brain samples. Performed chemical mapping and further semi-quantitative and statistical analysis showed that the use of the KD during pregnancy, in general, does not lead to the brain biochemical anomalies in 2 and 6 days old rats. The exception from this rule was increased relative (comparing to proteins) content of compounds containing phosphate groups in white matter and cortex of 2 days old rats exposed prenatally to KD. Greater number of abnormalities was found in brains of the 14 days old offspring of KD-fed mothers. They included the increase of the relative level of compounds containing carbonyl groups (in cortex as well as multiform and molecular cells of the hippocampal formation) as well as the decrease of the relative content of lipids and their structural changes (in white matter). What is more, the surface of the internal capsule (structure of the white matter) determined for this age group was smaller in animals subjected to prenatal KD exposure. The observed changes seem to arise from the elevated exposition to ketone bodies during a fetus life and the disturbance of lipid metabolism after prenatal exposure to the KD. These changes may be also associated with the processes of compensation of mother organism, which slowly began to make up for the deficiencies in carbohydrates postpartum.

J Anim Physiol Anim Nutr (Berl) 2022; 106:1149-1161. [PMID: 35312129 DOI: 10.1111/jpn.13707] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 12/08/2021] [Accepted: 03/01/2022] [Indexed: 01/14/2023]
Abstract
The study was aimed to ascertain whether continuation or change in the offspring of the diet consumed by the parents modulates, in later life, the previously programmed bone metabolism. We used adult Wistar rats (16 males; 32 females), divided into groups that were fed either a standard (diet S) or a high-energy (diet F). After 90 days of obesity induction, the rats were submitted to obtain female offspring from parents S and F. The offspring stayed with their mothers until 21 days of age (weaning day). Our previous studies have proved the programming effects of parental obesity on the skeletal system of their offspring at the age of 21 days. Weaned female offspring were divided into groups: S/S-parents and offspring fed the S diet; S/F-parents fed the S diet and offspring fed the F diet; F/S-parents fed the diet F and offspring with the diet S; F/F-parents and offspring fed the F diet (F/F). After sacrifice, isolated femurs were assessed by peripheral quantitative computed tomography and by a three-point bending test. The bones were examined at 49 and 90 days of life. We found that nutritional programming has a significant influence on the development and metabolism of the skeletal system in females during growth and maturity. Moreover, the modification of nutrition alters the metabolism of bone tissue, and the osteotropic effects vary depending on the nature of the change, as well as the stage of development. Reducing the caloric content of the diet inhibits the mineralization and decreases the mechanical strength of the bones while increasing the caloric content of the diet has a beneficial osteotropic effect.

Abstract
Maternal diet is key to the progeny's health since it may impact on the offspring's adult life. In this study, mice dams received standard (CONT), restrictive (RD), or hypercaloric (HD) diets during mating, pregnancy, and lactation. Male offspring of each group of dams also received these diets: CONT, RD, HD. Aiming to evaluate the oxidative stress in the adipose tissue, reactive oxygen species (ROS) production, catalase (CAT), and superoxide dismutase (SOD) activities were analyzed in dams and offspring. In the adipose tissue and hypothalamus, gene expression of prolactin (Prlr) and estrogen alpha (Esr1) receptors was performed in dams and offspring. Protein expression of Stat5 was evaluated in the adipose tissue of the offspring from RD-fed dams. HD-fed dams increased triglycerides and leptin serum concentrations, and decreased SOD activity in the adipose tissue. In the offspring's adipose tissue, we observed a maternal diet effect caused by HD, with increased ROS production and SOD and CAT activities. Gene expression of Prlr and Esr1 in the offspring's adipose tissue was decreased due to maternal RD. Mice from HD-fed dams showed higher Stat5 expression compared to the offspring from CONT and RD dams in the adipose tissue. In the hypothalamus, we found decreased expression of Prlr in RD and HD dams, compared to CONT; and a maternal diet effect on Prlr and Esr1 gene expression in the offspring. In conclusion, we can affirm that maternal nutrition impacts the redox state and influences the gene expression of Prlr and Esr1, which are involved in energy metabolism, both peripherally and centrally in the adult life of the female offspring.

Abstract
Maternal high-fat diet (HFD) often results in intrauterine and feto-placental inflammation, and increases the risks of fetal programming of metabolic diseases. Intake of prebiotic is reported beneficial. However, its effects on HFD during pregnancy and lactation is not known. We evaluated the maternal intake of fructooligosaccharide (FOS) and its impact on placental inflammation, offspring's adiposity, glucose, and lipid metabolism in their later life. Female Golden Syrian hamsters were fed with a control diet (CD, 26.4 % energy from fat) or HFD (60.7% energy from fat) in the presence or absence of FOS from preconception until lactation. All pups were switched over to CD after lactation and continued until the end. Placental inflammation was upregulated in HFD-fed dam, as measured by a high concentration of hsCRP in the serum and amniotic fluid. Neutrophil infiltration was significantly increased in the decidua through the chorionic layer of the placenta. The expression of pro-inflammatory cytokines such as COX2, NFκβ, IL-8, TGFβ mRNA was increased in the chorioamniotic membrane (P <.05). The HFD/CD hamsters had more adiposity, higher triglyceride, and low HDL at 12 months of age compared to CD/CD (P <.05). However, HFD+FOS/CD-fed hamsters prevented adverse effects such as placental inflammation, neutrophil infiltration, glucose, and lipid profiles in the offspring (P <.05). Anti-inflammatory and lipid-lowering effects of FOS may reduce placental inflammation by lowering neutrophil infiltration and decreasing the production of pro-inflammatory cytokines. Intake of FOS during pregnancy may be beneficial in maintaining lipid metabolism and preventing excess adiposity for mother and their offspring.

Abstract
The ‘Developmental Origins of Health and Diseases’ hypothesis posits that prenatal maternal diet influences offspring growth and later life health outcomes. Dietary assessment has focused on selected nutrients. However, this approach does not consider the complex interactions between foods and nutrients. To provide a more comprehensive approach to public health, dietary indices have been developed to assess dietary quality, dietary inflammation and risk factors for non-communicable diseases. Thus far, their use in the context of placental development is limited and associations with offspring outcomes have been inconsistent. Although epidemiological studies have focused on the role of maternal diet on foetal programming, the underlying mechanisms are still poorly understood. Some evidence suggests these associations may be driven by placental and epigenetic changes. In this narrative review, we examine the current literature regarding relationships between key validated diet quality scores (Dietary Inflammatory Index [DII], Mediterranean diet [MD], Healthy Eating Index [HEI], Alternative Healthy Eating Index [AHEI], Dietary Approaches to Stop Hypertension [DASH], Glycaemic Index [GI] and Glycaemic Load [GL]) in pregnancy and birth and long-term offspring outcomes. We summarise findings, discuss potential underlying placental and epigenetic mechanisms, in particular DNA methylation, and highlight the need for further research and public health strategies that incorporate diet quality and epigenetics.

Abstract
CONTEXT Excessive consumption of high-fat diets has increased in the population over time and is harmful to female fertility. OBJECTIVE To investigate and discuss the effects of a high-fat diet on ovarian follicles in rodents. DATA SOURCE A systematic literature search of PubMed, EMBASE, Web of Science, and SCOPUS was carried out. DATA EXTRACTION Study characteristics, including study design, population, intervention, outcome, and risk of bias were analyzed. DATA ANALYSIS Twenty-two articles were included in a systematic review. Given the availability of studies, a quantitative meta-analysis included 12 studies that were performed for outcomes. There was a decrease in primordial follicles in female rodents that received a high-fat diet compared with the standard diet group. The offspring of mothers exposed to a high-fat diet showed an increased number of cystic follicles and a decreased number of secondary follicles and antral follicles, compared with the control diet group. Therefore, these high-fat diet-induced follicular alterations might impair the fertility of dams and their female newborns. CONCLUSION The consumption of a high-fat diet causes damage to ovarian follicular development, and this commitment will persist in the next generation.

Abstract
BACKGROUND Changes in the nutritional environment in utero induced by maternal obesity (MO) lead to foetal metabolic dysfunction predisposing offspring to later-life metabolic diseases. Since mitochondria play a crucial role in hepatic metabolism and function, we hypothesized that MO prior to conception and throughout pregnancy programmes foetal sheep liver mitochondrial phenotype. MATERIAL AND METHODS Ewes ate an obesogenic diet (150% requirements; MO), or 100% requirements (CTR), from 60 days prior to conception. Foetal livers were removed at 0.9 gestation. We measured foetal liver mitochondrial DNA copy number, activity of superoxide dismutase, cathepsins B and D and selected protein content, total phospholipids and cardiolipin and activity of mitochondrial respiratory chain complexes. RESULTS A significant decrease in activities of mitochondrial complexes I, II-III and IV, but not aconitase, was observed in MO. In the antioxidant machinery, there was a significant increase in activity of total superoxide dismutase (SOD) and SOD2 in MO. However, no differences were found regarding autophagy-related protein content (p62, beclin-I, LC3-I, LC3-II and Lamp2A) and cathepsin B and D activities. A 21.5% decrease in total mitochondrial phospholipid was observed in MO. CONCLUSIONS The data indicate that MO impairs foetal hepatic mitochondrial oxidative capacity and affects total mitochondrial phospholipid content. In addition, MO affects the regulation of foetal liver redox pathways, indicating metabolic adaptations to the higher foetal lipid environment. Consequences of in utero programming of foetal hepatic metabolism may persist and compromise mitochondrial bioenergetics in later life, and increase susceptibility to metabolic diseases.

Abstract
Obesity is a major health risk, with junk food consumption playing a central role in weight gain, because of its high palatability and high-energy nutrients. The Cafeteria (CAF) diet model for animal experiments consists of the same tasty but unhealthy food products that people eat (e.g. hot dogs and muffins), and considers variety, novelty and secondary food features, such as smell and texture. This model, therefore, mimics human eating patterns better than other models. In this paper, we systematically review studies that have used a CAF diet in behavioral experiments and propose a standardized CAF diet protocol. The proposed diet is ad libitum and voluntary; combines different textures, nutrients and tastes, including salty and sweet products; and it is rotated and varied. Our summary of the behavioral effects of CAF diet show that it alters meal patterns, reduces the hedonic value of other rewards, and tends to reduce stress and spatial memory. So far, no clear effects of CAF diet were found on locomotor activity, impulsivity, coping and social behavior.
