(Submitter supplied) To test the hypothesis that the disruption caused by TCDD in cardiomyocytes results from changes in DNA methylation and gene expression patterns, we established a stable mouse embryonic stem cell line expressing a puromycin resistance selectable marker under the control of the cardiomyocyte-specific Nkx2.5 promoter. Differentiation of these cells in the presence of puromycin induces the expression of a large suite of cardiomyocyte specific markers. more...

(Submitter supplied) Epigenetic modifications have emerged as central players in the coordination of gene expression networks during cardiac development. While several studies have investigated the role of histone modifications during heart development, relatively little is known about the role of DNA methylation. The purpose of the current study was to determine whether DNA methylation plays an important role in guiding transcriptional changes during the neonatal period, which is an important developmental window for cardiac maturation and cardiomyocyte cell cycle arrest. more...

(Submitter supplied) The differentiation to cardiomyocytes is a prerequisite and an important part of heart development. A good understanding of the complicated cardiomyocyte differentiation process benefits cardiogenesis study. Embryonic stem cells (ESCs), cell lines with infinite ability to proliferate and to be differentiated into all cell types of the adult body, are important research tools for investigation of differentiation and meanwhile good models for developmental research. more...

(Submitter supplied) The dioxin congener 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes a wide range of toxic effects in rodent species, all of which are mediated by a ligand-dependent transcription-factor, the aryl hydrocarbon receptor (AHR). The Han/Wistar (Kuopio) (H/W) strain shows exceptional resistance to many TCDD-induced toxicities; the LD50 of >9600 µg/kg for H/W rats is higher than for any other wild-type mammal known. more...

(Submitter supplied) Dioxin and dioxin-related polychlorinated biphenyls are potent toxicants with association with developmental heart defects and congenital heart diseases. However, the underlying mechanism of their developmental toxicity is not fully understood. Further, different animals show distinct susceptibility and phenotypes after exposure, suggesting possible species-specific effects. Using a human embryonic stem cell (ESC) cardiomyocyte differentiation model, we examined the impact, susceptible window, and dosage of 2,3,7,8‑tetrachlorodibenzo‑p‑dioxin (TCDD) on human cardiac development. more...

(Submitter supplied) Purpose: This study aimed to identify differentially expressed genes including alternative splice variants in embryonic ventricles following in utero caffeine treatment. Methods: Pregnant CD-1 mice were injected with 20 mg/kg of caffeine or vehicle control daily from embryonic day (E) 6.5-9.5. On E10.5, total RNA was isolated from embryonic ventricles and used for transcriptomic RNA sequencing with Illumina HiSeq 2000 (1X75bp). more...

(Submitter supplied) Pregnant C57Bl6N mice were treated with 0 (corn oil), 1.5, 3.0, or 6.0 ug/kg TCDD on gd14.5. Fetal hearts were collected on gd17.5. Hearts from each litter were pooled onto one chip. 4 replicates of each condition were run on affymetrix MG_U74Av2 chips, using standard affymetrix protocols and controls.

(Submitter supplied) RNA-Seq was used to analyze and compare temporal TCDD-induced gene expression changes in primary human, mouse and rat B cells. Most of the differentially expressed genes exibited species-specific expression. Cross-species comparison identified 28 orthologs commonly deregulated in all 3 species. The study provides new insight into mechanisms of TCDD-induced suppression of B cell effector function.

(Submitter supplied) 2,3,7,8–tetrachlorodibenzo-p-dixion (TCDD) is the most potent of the dioxin congeners, capable of causing a wide range of toxic effects across numerous animal models. Previous studies have demonstrated that males and females of the same species can display divergent sensitivity phenotypes to TCDD toxicities. Although it is now clear that most TCDD-induced toxic outcomes are mediated by the aryl hydrocarbon receptor (AHR), the mechanism of differential responses to TCDD exposure between sexes remains largely unknown. more...

(Submitter supplied) Dioxin is one of the most common historic industrial contaminants with several major industry and government accidents having exposed large numbers of the worldwide population over the past century. Previous rat studies have demonstrated the ability of dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)) exposure to promote the epigenetic transgenerational inheritance of disease susceptibility in subsequent generations. more...
