Genes responsive to bisphenol A in testicular Sertoli cells. Mus musculus

We performed global scale microarray analysis to identify detailed mechanisms by which bisphenol A (BPA) induce cell death by using an Affymetrix GeneChip system. Testicular Sertoli TTE3 cells used in the present study were derived from transgenic mice harboring a temperature-sensitive simian virus 40 large T-antigen. Cell death accompanying endoplasmic reticulum stress was observed in the cells treated with 0.2 mM BPA. Of the 22,690 probe sets analyzed, approximately 1,300 genes were down- and up-regulated by a factor of 2.0 or greater in the cells treated with BPA. Keywords: bisphenol A, gene expression, testicular Sertoli cell Overall design: TTE3 cells were treated with BPA for 0, 3, 6, and 12 h. Total RNA samples were prepared from the cells. Gene expression was analyzed by an Affymetrix GeneChip® system with the Mouse Expression Array 430A which was spotted with 22,690 probe sets. Sample preparation for array hybridization was carried out as described in the manufacture’s instructions.
