Project description:Since Japanese quail and chicken belong to the same order Galliforms, DNA sequence of both species are highly conserved and proved to be applicable for various analyses each other. Quail are commonly used to address physiological questions for reasons of economy. To test whether chicken microarrays are useful to quail samples, we compared hybridization signals of chicken and quail genomic DNA on Affymetrix chicken genome array. Keywords: comparative genomic hybridization

Project description:A variety of environmental factors have been shown to induce the epigenetic transgenerational inheritance of disease and phenotypic variation. This involves the germline transmission of epigenetic information between generations. Exposure specific sperm epimutations have been previously observed. The current study was designed to investigate the potential role genetic mutations have in the process, using copy number variations (CNV). In the first (F1) generation following exposure negligible CNV were identified, but in the transgenerational F3 generation a significant increase in CNV were identified in the sperm. The genome-wide differential DNA methylation regions (epimutations) were correlated with the genome locations of the CNV. Observations indicate the environmental induction of the epigenetic transgenerational inheritance of sperm epimutations promotes genome instability such that genetic CNV mutations are acquired in later generations. A combination of epigenetics and genetics is suggested to be involved in the transgenerational phenotypes.

Project description:The epigenetic transgenerational actions of environmental toxicants and relevant mixtures on ovarian disease was investigated with the use of a fungicide, a pesticide mixture, a plastic mixture, dioxin and a hydrocarbon mixture. After transient exposure of an F0 gestating female rat during embryonic gonadal sex determination, the F1, F2 and F3 generation progeny adult onset ovarian disease was assessed. Transgenerational disease phenotypes observed included an increase in cysts resembling human polycystic ovarian disease (PCO) and a decrease in the ovarian primordial follicle pool size resembling premature ovarian failure (POF). The F3 generation granulosa cells were isolated and found to have a transgenerational effect on the transcriptome and epigenome (differential DNA methylation). Epigenetic biomarkers for environmental exposure and associated gene networks were identified. Epigenetic transgenerational inheritance of ovarian disease states were induced by different classes of environmental compounds suggesting a role of environmental epigenetics in ovarian disease etiology. We used transcriptome microarray analysis to determine genes expressed differentially between F3 control and F3 vinclozolin lineage rat ovary granulosa cell and see which genes might be connected to or cause observed ovary diseases RNA samples from granulosa cell of 3 F3-control lineage groups are compared to granulosa cell of 3 F3-vinclozolin lineage groups

Quail are commonly used to address physiological questions for reasons of economy. To test whether chicken microarrays are useful to quail samples, we compared hybridization signals of chicken and quail genomic DNA on Affymetrix chicken genome array. Experiment Overall Design: Genomic DNA of female chicken and quail were extracted individually from liver of three birds and hybridized on Affymetrix microarrays. Samples were analyzed in triplicate set of array (three biological replicates).

After transient exposure of an F0 gestating female rat during embryonic gonadal sex determination, the F1 and F3 generation progeny adult onset ovarian disease was assessed. Transgenerational disease phenotypes observed included an increase in cysts resembling human polycystic ovarian disease (PCO) and a decrease in the ovarian primordial follicle pool size resembling primary ovarian insufficiency (POI). The F3 generation granulosa cells were isolated and found to have a transgenerational effect on the transcriptome and epigenome (differential DNA methylation). Epigenetic biomarkers for environmental exposure and associated gene networks were identified. Epigenetic transgenerational inheritance of ovarian disease states was induced by all the different classes of environmental compounds, suggesting a role of environmental epigenetics in ovarian disease etiology.

Project description:The current study was designed to use a rodent model to determine if exposure to the chemotherapy drug ifosfamide during puberty can induce altered phenotypes and disease in the grand-offspring of exposed individuals through epigenetic transgenerational inheritance. Numerous toxicant exposures during critical developmental windows can have generational impacts through this non-genetic inheritance mechanism. Pathologies such as delayed pubertal onset, kidney disease and multiple pathologies were observed to be significantly more frequent in the F1 generation offspring of ifosfamide lineage females. The F2 generation grand-offspring ifosfamide lineage males had transgenerational pathology phenotypes of early pubertal onset and reduced testis pathology. Reduced levels of anxiety were observed in both males and females from the exposure lineage in the transgenerational F2 generation grand-offspring. Differential DNA methylated regions (DMRs) were also identified in chemotherapy and control lineages sperm in the F1 and F2 generations. The transgenerational alterations in sperm epigenetics provides a molecular mechanism for the ancestral impacts of chemotherapy. Therefore, chemotherapy exposure can impact pathology and disease susceptibility in subsequent generations.

Project description:Integrated breeding strategies are used to increase both the yield potential and stability of crops. Most of these approaches have a direct genetic basis. The utility of epigenetics in breeding to improve complex traits such as yield and stress tolerance is not clear. A better understanding of the status of the epigenome and its contribution to the agronomic performance would help in developing strategies to incorporate the epigenetic component of complex traits in breeding,Starting from isogenic canola lines, epilines were generated by selecting recursively during three generations for lines with a higher energy use efficiency and drought tolerance. These epilines were more energy use efficient, drought tolerant, high nitrogen use efficient, and higher yielding under suboptimal conditions. Moreover, these characteristics were transgenerational inheritable. Transcriptome comparison with a line selected for energy use efficiency only revealed common differentially expressed genes related to the onset of signaling events regulating stress tolerance. Genes related to salt, osmotic, abscisic acid and drought were specifically differentially expressed in the drought tolerant epilines. The status of the epigenome, scored as differential trimethylation of lysine 4 of histone 3, supports the energy use efficient and drought tolerant phenotype by facilitating transcription of the genes that are found to be differentially expressed.From these results it can be concluded that the epigenome can be shaped by selection to increase yield and stress tolerance. This acquired knowledge will support further development of strategies to incorporate epigenetics in breeding. To investigate the epigenetic effect on histone mark distribution of the EUE/PEG selection we performed ChIP-seq analyses. Native ChIP using an anti-H3K4me3 and no antibody (background control) was done on PEG1 and control plants.
