(Submitter supplied) The developmental origins of health and adult disease (DOHaD) hypothesis states that exposure to various environmental stressors early in life can elicit changes to the genome and epigenome thereby resulting in an increased susceptibility of a disease state during adulthood. Atrazine, a common herbicide used throughout the Midwestern United States for control of weeds on various crops frequently contaminates potable water supplies and is a suspected endocrine disrupting chemical. more...

(Submitter supplied) Atrazine is an agricultural herbicide used throughout the Midwestern United States that frequently contaminates potable water supplies resulting in human exposure. Using the zebrafish model system, an embryonic atrazine exposure was previously reported to decrease spawning rates with an increase in progesterone and ovarian follicular atresia in adult females. In addition, alterations in genes associated with distinct molecular pathways of the endocrine system were observed in brain and gonad tissue of the adult females and males. more...

(Submitter supplied) The herbicide atrazine, a suspected endocrine disrupting chemical (EDC), frequently contaminates potable water supplies. Studies suggest alterations in the neuroendocrine system along the hypothalamus-pituitary-gonadal axis; however, most studies address either developmental, pubertal, or adulthood exposures, with few investigations regarding a developmental origins hypothesis. In this study, zebrafish were exposed to 0, 0.3, 3, or 30 parts per billion (ppb) atrazine through embryogenesis and then allowed to mature with no additional chemical exposure. more...

(Submitter supplied) Atrazine is an herbicide applied to agricultural crops and is indicated to be an endocrine disruptor. Atrazine is frequently found to contaminate potable water supplies above the maximum contaminant level of 3 mg/L as defined by the U.S. Environmental Protection Agency. The developmental origin of adult disease hypothesis suggests that toxicant exposure during development can increase the risk of certain diseases during adulthood. more...

(Submitter supplied) According to the developmental origins of health and disease (DOHaD) hypothesis, exposure to environmental stressors during early development can cause genetic, epigenetic, or functional changes in tissues that increase disease risk later in life. Atrazine (ATZ) is a commonly used pesticide that frequently contaminates rural and urban water sources at levels above the 3 ppb maximum contaminant level set by the US Environmental Protection Agency. more...

(Submitter supplied) The study of epigenetic mechanisms of gene regulation and the role of these mechanisms in developmental reprogramming of the genome and disease susceptibility has increased in recent years. Molecular epigenetic mechanisms regulating gene expression include DNA methylation, histone modifications, and small non-coding RNAs (e.g., microRNAs). MicroRNAs (miRNAs) are short, single-stranded RNA that regulate post-transcriptional control of the translation of mRNA. more...

(Submitter supplied) Atrazine, a herbicide commonly applied to agricultural areas and a common contaminant of potable water supplies, is implicated as an endocrine-disrupting chemical (EDC) and potential carcinogen. Studies show that EDCs can cause irreversible changes in tissue formation, decreased reproductive potential, obesity, and cancer. The U.S. Environmental Protection Agency considers an atrazine concentration of ≤ 3 ppb in drinking water safe for consumption. more...

(Submitter supplied) Developmental lead (Pb) exposure has been linked to neurological health issues appearing in children. Results from non-human primate studies also suggest detrimental effects of an early life Pb exposure on neurological health, showing a pathological evidence of Alzheimer’s disease in the aged animal brain. To elucidate the impacts of a developmental Pb exposure on neurological health-related molecular changes occurring in the aged brain, aged zebrafish with a control treatment or an embryonic exposure to 100 µg/L Pb were subjected to a zebrafish-specific microarray analysis by sex. more...

(Submitter supplied) Endocrine disrupting chemicals (EDCs) exert significant effects on health and physiology, many of which are traceable to effects on stem cell programming underlying organismal development. Understanding risk of low-level, chronic EDC exposure will be enhanced by knowledge of effects on stem cells. We exposed rhesus monkey embryonic stem cells to low levels of five different EDCs for 28 days, and evaluated effects on gene expression by RNAseq transcriptome profiling. more...

(Submitter supplied) Purpose: Identify gene expression changes in whole intestines of Xenopus laevis embryos exposed to atrazine (35 mg/L) compared to DMSO controls Methods: NF 39 embryos were exposed to 35 mg/L ATR or DMSO control for 24 hours. After 24 hours of exposure, intestines from embryos of each treatment group were dissected from anesthetized embryos with sharpened forceps. The anterior portion of the embryo (including the head, heart, and foregut) were removed and discarded, leaving only the mid-and hindgut portion of the intestine. more...
