Abstract
The effects of nonylphenol (NP) were examined on brain gene expression profiles of F1 generation rats by means of microarray techniques. The mRNA were extracted from the brain of two-day-old F1 generation rats whose F0 male generation were treated with NP, then reversely transcribed to cDNA and labeled with Cy5 and Cy3 fluorescence. Subsequently, the cDNA probes were hybridized to the mouse 40S cDNA microarray and the fluorescent signals of Cy5 and Cy3 were scanned and analyzed. Sixteen identified genes were expressed significantly differently from control, including 13 down-regulated, of which five were related to brain energy metabolism. Data suggest that it is possible that NP affects function of energy metabolism in male rats when administered perinatally.
