Abstract
BACKGROUND Little is known about the transgenerational effect of nutrition deficiency in early life. This study aimed to evaluate the associations of fetal and childhood exposure to famine of parents with their offspring's risk of overweight during childhood. METHODS This analysis included a total of 3734 participants of the China Health and Nutrition Survey aged 1-17 years whose fathers and/or mothers were born in 1955-1966. These children were classified into subgroups according to parental famine exposure status (unexposed and exposed) and timing (fetal-exposed and childhood-exposed). Random effects models were applied to evaluate the associations of parental famine exposure with body mass index (BMI) and overweight of offspring. Fractional polynomial functions were adopted to describe trajectories of BMI against age. RESULTS Compared with children of unexposed parents, there was a lower risk of overweight among offspring of childhood-exposed fathers [OR (95%CI): 0.80 (0.61, 1.04)] or exposed parents [0.84 (0.68, 1.04)], particularly among male offspring, but not among those with exposed mothers only [0.98 (0.65, 1.47)]. For BMI, children with exposed mothers only had a slightly higher BMI [β(95%CI): 0.17 (-0.15, 0.49)], while those with exposed fathers only had no difference [-0.02 (-0.23, 0.19)] or exposed parents had a slightly lower BMI [-0.17 (-0.33, 0.00)] (p < 0.05 for interaction between maternal and paternal exposures). Stratified analysis showed little heterogeneity between male and female offspring, but the association between paternal childhood exposure to famine and lower overweight risk in offspring was more evident in high (vs low) paternal education group (p for interaction< 0.05). CONCLUSIONS The transgenerational associations of early-life exposure to famine with lower risks of child overweight may be via the paternal line and differ by the educational levels of parents. Further studies are warranted to confirm the results and reveal the biological mechanisms underlying.

Trends in Gliosis in Obesity, and the Role of Antioxidants as a Therapeutic Alternative. Antioxidants (Basel) 2022; 11:antiox11101972. [PMID: 36290695 PMCID: PMC9598641 DOI: 10.3390/antiox11101972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 09/23/2022] [Accepted: 09/29/2022] [Indexed: 11/16/2022] Open
Abstract
Obesity remains a global health problem. Chronic low-grade inflammation in this pathology has been related to comorbidities such as cognitive alterations that, in the long term, can lead to neurodegenerative diseases. Neuroinflammation or gliosis in patients with obesity and type 2 diabetes mellitus has been related to the effect of adipokines, high lipid levels and glucose, which increase the production of free radicals. Cerebral gliosis can be a risk factor for developing neurodegenerative diseases, and antioxidants could be an alternative for the prevention and treatment of neural comorbidities in obese patients. AIM Identify the immunological and oxidative stress mechanisms that produce gliosis in patients with obesity and propose antioxidants as an alternative to reducing neuroinflammation. METHOD Advanced searches were performed in scientific databases: PubMed, ProQuest, EBSCO, and the Science Citation index for research on the physiopathology of gliosis in obese patients and for the possible role of antioxidants in its management. CONCLUSION Patients with obesity can develop neuroinflammation, conditioned by various adipokines, excess lipids and glucose, which results in an increase in free radicals that must be neutralized with antioxidants to reduce gliosis and the risk of long-term neurodegeneration.

Abstract
The prenatal period, during which a fully formed newborn capable of surviving outside its mother's body is built from a single cell, is critical for human development. It is also the time when the foetus is particularly vulnerable to environmental factors, which may modulate the course of its development. Both epidemiological and animal studies have shown that foetal programming of physiological systems may alter the growth and function of organs and lead to pathology in adulthood. Nutrition is a particularly important environmental factor for the pregnant mother as it affects the condition of offspring. Numerous studies have shown that an unbalanced maternal metabolic status (under- or overnutrition) may cause long-lasting physiological and behavioural alterations, resulting in metabolic disorders, such as obesity and type 2 diabetes (T2DM). Various diets are used in laboratory settings in order to induce maternal obesity and metabolic disorders, and to alter the offspring development. The most popular models are: high-fat, high-sugar, high-fat-high-sugar, and cafeteria diets. Maternal undernutrition models are also used, which results in metabolic problems in offspring. Similarly to animal data, human studies have shown the influence of mothers' diets on the development of children. There is a strong link between the maternal diet and the birth weight, metabolic state, changes in the cardiovascular and central nervous system of the offspring. The mechanisms linking impaired foetal development and adult diseases remain under discussion. Epigenetic mechanisms are believed to play a major role in prenatal programming. Additionally, sexually dimorphic effects on offspring are observed. Therefore, further research on both sexes is necessary.

Characterization of the intergenerational impact of in utero and postnatal oxycodone exposure. Transl Psychiatry 2020; 10:329.

Abstract
Prescription opioid abuse during and after pregnancy is a rising public health concern. While earlier studies have documented that offspring exposed to opioids in utero have impaired neurodevelopment, a significant knowledge gap remains in comparing the overall development between offspring exposed in utero and postnatally. Adding a layer of complexity is the role of heredity in the overall development of these exposed offspring. To fill in these important knowledge gaps, the current study uses a preclinical rat model mimicking oxycodone (oxy) exposure in utero (IUO) and postnatally (PNO) to investigate comparative and intergenerational effects in the two different treatment groups. While significant phenotypic attributes were observed with the two treatments and across the two generations, RNA sequencing revealed alterations in the expression of key synaptic genes in the two exposed groups in both generations. RNA sequencing and post validation of genes using RT-PCR highlighted the differential expression of several neuropeptides associated with the hypocretin system, a system recently implicated in addiction. Further, behavior studies revealed anxiety-like behaviors and social deficits that persisted even in the subsequent generations in the two treatment groups. To summarize, our study for the first time reveals a new line of investigation on the potential risks associated with oxy use during and after pregnancy, specifically the disruption of neurodevelopment and intergenerational impact on behavior.

Abstract
Introduction: Obesity promotes hypothalamic inflammation and local morphological changes in astrocytes, including the increased expression of the astrocytic biomarker glial fibrillary acidic protein (GFAP), which is seen as a sign of neuroinflammation.Objective: This study aimed to observe the astrocytic expression of GFAP in different brain areas from female rats that received a hypercaloric (HD) or a normocaloric (ND) diet during puberty (F0 generation) as well as in their male pups (F1 generation).Methods: Female rats received highly palatable HD (Ensure®) or ND from postnatal day (PND) 23-65. On PND90-95, some were euthanized for the immunohistochemical study and some were mated to obtain the F1 generation. Male pups were immunochallenged on PND50 with lipopolysaccharide (LPS, 100 μg/kg) or 0.9% saline solution (1 mL/kg) intraperitoneal injection. Body weight (BW) and retroperitoneal fat weight (RFW) were recorded on PND95 for F0 generation and on PND50 for F1 generation. GFAP expression for both generations was assessed by morphometry in the parietal/frontal cortex, corpus callosum, nucleus accumbens, arcuate/periventricular nuclei of hypothalamus, pons, molecular/granular layers of cerebellum.Results: Female rats fed with HD presented a significant increase in the GFAP expression in all evaluated areas as well as in the RFW. Male rats born from mothers that received HD showed decreased GFAP expression, BW and RFW when treated with LPS in relation to those from mothers fed with ND.Discussion: HD induced astrogliosis in several brain areas in females from F0 generation and an adaptive phenotypic change of decreased GFAP expression in males from F1 generation after LPS challenge.

Abstract
AIMS The effects of maternal food restriction during gestation in F0 generation followed by hypercaloric diet (HD) during puberty in F1 generation (F1HD) were investigated on astrocyte behavior of F2 generation. Also, the astrocyte behavior, after an immune challenge, was examined by the immunohistochemical expression of glial fibrillary acidic protein (GFAP) in several brain areas. METHODS The body weight gain (BW) during development and in postnatal day (PND) 90-95, the retroperitoneal fat weight (RPF), and the size of larger and smaller adipocytes in the F1 generation were assessed to observe the effects of HD in female rats. The BW, RPF weight and size of smaller and larger adipocytes was also measured to evaluate the transgenerational effects of F0 and F1 diets on F2 generation, treated or not with lipopolysaccharide (LPS). KEY FINDINGS The F1HD group exhibited a higher BW gain than the F1 treated with normocaloric diet (ND, group F1ND), from weaning to PND65. In the frontal/parietal cortex, nucleus accumbens, hypothalamic arcuate/periventricular nuclei, molecular/granular layers of the cerebellum areas, excepting the pons, GFAP expression was greater in F1HD group relative to F1ND group. A reduced GFAP expression was observed in both groups born from F1 generation fed with HD (groups F2HDS and F2HDLPS) in relation to F2 generation born from dams fed with ND (groups F2NDS and F2NDLPS), independently of LPS challenge. SIGNIFICANCE These data show an attenuation of LPS effect on GFAP expression, probably by a transgenerational effect of both maternal food deprivation in F0 generation and HD in F1 generation.
