(Submitter supplied) Ethanol exposure during prenatal development causes fetal alcohol spectrum disorder (FASD), the most frequent preventable birth defect and neurodevelopmental disability syndrome. The molecular targets of ethanol toxicity during development are poorly understood. Developmental stages surrounding gastrulation are very sensitive to ethanol exposure. To understand the effects of ethanol on early transcripts during embryogenesis, we treated zebrafish embryos with ethanol during pre-gastrulation period and examined the transcripts by Affymetrix GeneChip microarray before gastrulation. more...

(Submitter supplied) Gene expression was measured using microarrays in 8 hour postfertilization embryos, comparing control versus ethanol-treated (2 to 8 hours postfertilization) embryos. This experiment was performed to determine the gene expression changes that occur in response to ethanol treatment as a model of fetal alcohol spectrum disorder. Fetal alcohol spectrum disorder (FASD) occurs when pregnant mothers consume alcohol, causing embryonic ethanol exposure and characteristic birth defects that include craniofacial, neural and cardiac defects. more...

Analysis of embryos treated with ethanol in embryo medium from 2 hours post fertilization (hpf) to 8hpf. FASD occurs when pregnant mothers consume alcohol, causing embryonic ethanol exposure and characteristic developmental defects. Results provide insight into molecular basis of FASD pathogenesis.

(Submitter supplied) The glucose-sensing Mondo pathway regulates expression of metabolic genes in mammals. Here, we have revealed an unexpected role of this pathway in vertebrate embryonic development. We characterized Mondo pathway function in the zebrafish and showed that knock-down of mondoa impaired the early morphogenetic movement of epiboly in zebrafish embryos. Expression of nsdhl , an enzyme of cholesterol and pregnenolone synthesis, was strongly reduced in these embryos. more...

(Submitter supplied) In the early zebrafish embryo, the developing genome profile can be interfered with by exposure to pentachlorophenol, and some specific sets of genes are up-regulated or down-regulated. We used microarrays to detail the global program of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process.

(Submitter supplied) Ethanol is a well-known teratogen. While this teratogenic potential is well-characterized clinically, the mechanisms through which ethanol exposure results in developmental defects remain unclear. Here we use the zebrafish model to elucidate eye-specific mechanisms that may underlie ethanol-mediated microphthalmia (reduced eye size), using time-series microarray analysis of gene expression of eye tissues of embryos exposed to 1.5% ethanol vs. more...

(Submitter supplied) Prenatal exposure to ethanol leads to a myriad of developmental disorders known as fetal alcohol spectrum disorder, often characterized by growth and mental retardation, central nervous system damage and specific craniofacial dysmorphic features. Although the exact mechanisms of ethanol toxicity are not well understood it is known that ethanol exposure during development affects the expression of several genes involved in cell cycle control, apoptosis and transcription. more...

(Submitter supplied) Sox31 is a member of the zebrafish SoxB1 subfamily, and its expression can be detected both pre- and post-MBT. To distinguish the function of its maternal and zygotic transcripts, a splice blocking morpholino (Sb MO) was designed to interfere with the processing of new, zygotically synthesised mRNAs without interfering with mRNAs of maternal origin. Developmental arrest was observed in Sb MO which could not bypass MBT. more...

(Submitter supplied) The B1 SOX transcription factors SOX1/2/3/19 have been implicated in various processes of early embryogenesis. However, their regulatory functions in stages from the blastula to early neurula remain largely unknown, primarily because loss-of-function studies have not been informative to date. In our present study, we systematically knocked down the B1 sox genes in zebrafish. Only the quadruple knockdown of the four B1 sox genes sox2/3/19a/19b, which are active in the early embryo, resulted in very severe developmental abnormalities, confirming that the B1 sox genes are functionally redundant. more...

(Submitter supplied) Estrogen signaling is important for vertebrate embryonic development.

Zebrafish embryos were exposed to 1 µM 17β-estradiol from 3 hours post fertilization to 4 days post fertilization, harvested daily and subjected to RNA extraction for transcriptome analysis using microarrays. more...
