Paternally-induced transgenerational environmental reprogramming of metabolic gene expression in mammals (Affymetrix)

ABSTRACT: Epigenetic information can be inherited through the mammalian germline, and represents a plausible transgenerational carrier of environmental information. To test whether transgenerational inheritance of environmental information occurs in mammals, we carried out an expression profiling screen for genes in mice that responded to paternal diet. Characterising the change in RNA expression in sperm in response to different paternal diets. Examination of the effect of different diets, control diet, low-protein diet and caloric-restriction diet, on the RNA expression in the sperm. 8 samples: 3 are control diets and 2 are low protein diets 1 caloric restriction diet, and 2 samples from Epidydimal tissue.

Epigenetic information can be inherited through the mammalian germline and represents a plausible transgenerational carrier of environmental information. To test whether transgenerational inheritance of environmental information occurs in mammals, we carried out an expression profiling screen for genes in mice that responded to paternal diet. Offspring of males fed a low-protein diet exhibited elevated hepatic expression of many genes involved in lipid and cholesterol biosynthesis and decreased ...[more]

Paternally-induced transgenerational environmental reprogramming of metabolic gene expression in mammals (meDIP)

Project description:Epigenetic information can be inherited through the mammalian germline, and represents a plausible transgenerational carrier of environmental information. To test whether transgenerational inheritance of environmental information occurs in mammals, we carried out an expression profiling screen for genes in mice that responded to paternal diet. As part of this analysis, we chracterise the changes in sperm cytosine methylation in response to different diets. Characterizing the RNA exression changes in livers of offspring mice in response to the paternal diet, comparing between low-protein diet and control-diet. Examination the effect of 3 different paternal diets, control diet, Caloric Restriction and low-protein diet, on sperm cytosine methylation.

Paternally-induced transgenerational environmental reprogramming of metabolic gene expression in mammals (dye swap)

Project description:Epigenetic information can be inherited through the mammalian germline, and represents a plausible transgenerational carrier of environmental information. To test whether transgenerational inheritance of environmental information occurs in mammals, we carried out an expression profiling screen for genes in mice that responded to paternal diet. Characterizing the RNA exression changes in livers of offspring mice in response to the paternal diet, comparing between low-protein diet and control-diet. Examination of the effect of 2 different paternal diets, control diet and low-protein diet, on the mRNA expression in the liver of the offsprinngs. 26 samples: including Control diet vs. Low-protein (with dye swap), and Control diet vs. Low-protein after fasting the mice.

Low paternal dietary folate alters the sperm epigenome and is associated with negative pregnancy outcomes

Project description:Epidemiological studies suggest that a fatherâ€™s diet can influence offspring health. A proposed mechanism for paternal transmission of environmental information is via the sperm epigenome. The epigenome includes heritable information such as DNA methylation. We hypothesized that the dietary supply of methyl donors would alter epigenetic reprogramming in sperm. This hypothesis was examined by feeding male mice a folate deficient (FD) and folate sufficient (FS) diets and then generating and analyzing DNA methylation profiles of their sperm. C57BL/6 males were fed either the FS or FD diet throughout life (FS, n=32; FD, n=35; 2-3 month old). Pooled gene promoter DNA methylation profiles were generated from the sperm of three FS males and four FD males using the method of MeDIP (Methylated DNA Immunoprecipitation) followed by microarray hybridization.

MeDIP-seq of ICR mouse sperm with different combinations of in utero undernutrition and postnatal undernutrition

Project description:Maternal caloric restriction during the last week of gestation resulted in low birth weight (LBW) and increased risk of LBW-associated metabolic diseases in adult life. The metabolic phenotypes transmitted to F2 generation by paternal manner without additional altered nutrition. To investigate the mechanism of this intergenerational inheritance, two Cohorts were exposed to different magnitudes of undernutrition both in utero during the last week of gestation and/or postnatal until weaning. We performed MeDIP-seq on the genomic DNA from sperm collected from these mice.

small RNA-seq of ICR mouse sperm with different combinations of in utero undernutrition and post natal undernutrition

Project description:Maternal caloric restriction during the last week of gestation resulted in a low birth weight (LBW) and increased risk of LBW-associated metabolic diseases in adult life. The metabolic phenotypes transmitted to F2 generation by paternal manner without additional altered nutrition. To investigate the mechanism of this intergenerational inheritance, two Cohorts were exposed to different magnitudes of unternourition both in utero during the last week of gestation and/or post nataly until weaning. We performed small RNA-seq on non-coding RNA from sperm collected from these mice. Small RNA libraries were size-selected to be between 132 to 200 bp (including adapter) after library amplification.
