bisphenol A

(bĭs-fēn′ŏl) [L. bis, twice + ″],

BPA

A chemical used in many consumer products to increase their durability and toughness. Its chemical formula is 2,2–bis (4,4′-hydroxyphenyl) propane. It is used principally in manufacturing polycarbonates and epoxy resins. It has estrogen-like effects in animal tissue. Some studies have suggested that BPA has negative hormonal effects on adults and the developing fetus.

Surprisingly enough, despite increase in expression of BPA concentration (25 and 125 [micro]g), the increased expression was not dependent on increased bisphenol A condensation; so gene expression was decreased at every level compared to previous level; and, contrary to GADD45B gene expression, the difference was not further significant at the concentration of 125 [micro]g of bisphenol A compared to the control group (Figure 3).
