High intake of dietary sugar enhances bisphenol A (BPA) disruption and reveals ribosome-mediated pathways of toxicity: Acute Exposure


ABSTRACT: Fly strain y[1]; bw[1]; e[4]; ci[1] ey[R] was obtained from the Bloomington Stock Center. Flies were reared in incubators at 25°C, 65% of relative humidity, and photoperiod of 12 hours. For gene expression analyses flies were exposed to BPA, DEHP, and high sugar for 48 hours (acute exposure). After exposure, they were flash-frozen in liquid nitrogen. Four replicas of each sample were collected and stored at -80°C. Total RNA was extracted from whole flies using TRIzol (Life Technologies). The synthesis of cDNA and its labeling with fluorescent dyes (Cy3 and Cy5) as well as hybridization reactions were carried out using 3DNA protocols and reagents (Genisphere). Slides were scanned using Axon 400B scanner (Axon Instruments) and GenePix Pro 6.0 software. Foreground fluorescence of dye intensities was normalized by the Loess method in Bioconductor / Limma. Dye "swaps," loop design.

Bisphenol A (BPA) is an organic compound to which human populations are ubiquitously exposed. Epidemiological data suggest BPA exposure might be associated with higher rates of diabetes and reproductive anomalies. Health concerns also include transgenerational consequences, but these mechanisms are crudely defined. Similarly, little is known about synergistic interactions between BPA and other substances. Here we show that acute and chronic exposure to BPA causes genome-wide modulation of severa  ...[more]
