Exercise during pregnancy prevents parental obesity-induced decline of metabolic function in adult offspring [Bisulfite-Seq]

Project description:It is known that both maternal and paternal health/disease can influence the early development and later metabolic homeostasis of the offspring. We investigated whether maternal exercise during gestation alone could protect the offspring from the adverse effects of either maternal or paternal obesity induced by high-fat diet (HFD). To understand the underlying mechanisms we performed transcriptomics, whole-genome DNA methylation and targeted DNA methylation analysis at the metabolic master regulator, peroxisome proliferator-activated receptor g coactivator-1a (Pgc-1a) promoter in the adult offspring skeletal muscle. Both maternal and paternal HFD resulted in impaired glucose tolerance in the offspring at 9 months of age. Maternal exercise during gestation completely mitigated this metabolic impairment induced by either maternal or paternal HFD. Adult offspring exposed to either maternal or paternal HFD without exercise during gestation had skeletal muscle transcriptional profiles enriched in genes regulating inflammation and immune responses, whereas maternal exercise resulted in a transcriptional profile that was more similar to control offspring from normal chow fed parents. Changes in promoter and CpG DNA methylation were detected between the groups but did not explain the transcriptional changes. Maternal HFD increased methylation of the Pgc-1α promoter at CpG -260, which was prevented by maternal exercise. Paternal HFD did not affect the methylation of the Pgc-1α promoter. These findings demonstrate the negative consequences of maternal and paternal obesity for the offspring’s metabolic outcomes later in life and the clear benefits of maternal exercise during gestation. The mechanisms involve transcriptional regulation of skeletal muscle likely through multiple types of epigenetic modifications.

Transcriptomic responses predict the toxic effect of parental combined exposure to DBP and DiBP on the early development of zebrafish offspring

Project description:Dibutyl phthalate (DBP) and diisobutyl phthalate (DiBP) have been reported to exhibit reproductive toxicity and may pose a threat to their offspring. However, the combined effect of DBP and DiBP on offspring remains unclear, especially for aquatic organisms. The aims of this study were to assess the effects of parental combined exposure to DBP and DiBP on early development of zebrafish offspring, and to explore the potential molecular mechanisms involved. The early developmental indicators and transcriptomic profiles of F1 larvae were examined after parental exposure to DBP, DiBP and their mixtures (Mix) for 30 days. Results showed that parental exposure to DBP and DiBP, alone or in combination, resulted in increasing hatchability at 48 hpf and heart rate at 96 hpf, and affected the malformation and mortality in F1 larvae. Generalized linear model (GLM) indicated that the interactive effects between DBP and DiBP on the mortality and malformation of F1 larvae was antagonistic. The transcriptomic analysis predicted that the molecular mechanisms of parental combined exposure were different from those of either chemical alone, disruption of the molecular function involving unfolded protein binding, E-box binding and photoreceptor activity in F1 larvae could be the mechanism of action after parental combined exposure.

No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (liver)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal "high carbohydrate/low protein" diet was assessed on progeny. To this purpose, two-year old males and females rainbow trout were fed either a control diet or a "high carbohydrate/low protein" diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, hepatic transcriptomes were compared to detect any impact of the parental diet on offspring metabolism.

Parental exposure to environmental stress results in evolutionarily conserved intergenerational changes in offspring gene expression

Project description:These data demonstrate that parental exposure to bacterial infection and osmotic stress intergenerational changes in offspring gene expression in C. elegans, C. kamaaina, C. briggsae and C. tropicalis. Many of these intergenerational changes in gene expression are observed in multiple species and this data identified >250 genes that exhibit intergenerational changes in expression in all species tested.

No adverse effect of a parental low protein/high carbohydrate diet on their offspring, in rainbow trout (muscle)

Project description:In rainbow trout (Oncorhynchus mykiss), the effect of a paternal and a maternal high carbohydrate-low protein diet was assessed on progeny at long term. To this purpose, two-year old male and female rainbow trout were fed either a control diet or a high carbohydrate/low protein diet for an entire reproductive cycle for females and for 5 months for males. Crossed-fertilizations were carried out in order to obtain 4 groups of offspring. Offspring were fed with a commercial diet until they reached a market size. At this stage, muscle transcriptomes were analysed to detect any effect of the parental diet on offspring metabolism.

Parental exposure to gamma radiation causes progressively altered transcriptomes that are linked to adverse effects in zebrafish offspring

Project description:In zebrafish, parental exposure to ionizing radiation has been associated with effects in offspring, such as increased DNA damage and reactive oxygen species. Here, we assessed short (one month) and long term effects (one year) on gene expression in embryonic offspring (5.5 hours post fertilization) from zebrafish exposed during gametogenesis to gamma radiation (8.7 or 53 mGy/h for 27 days, total dose 5.2 or 31 Gy). One month after exposure, a global change in gene expression was observed in offspring from the 53 mGy/h group, followed by embryonic death at late gastrula, whereas offspring from the 8.7 mGy/h group was unaffected. One year after exposure, embryos from the 8.7 mGy/h group exhibited 2455(61.8% downregulated) differentially expressed genes. Overlaps in differentially expressed genes and enriched biological pathways were evident between the 53 mGy/h group one month and 8.7 mGy/h one year after exposure, which could be linked to effects in adults and offspring, such as DNA damage and lipid peroxidation. Interestingly, pathways between the two groups were oppositely regulated. Our results indicate latent effects following ionizing radiation exposure in parents that can be transmitted to offspring and warrants monitoring effects over subsequent generations.
