ESR1 and myocarditis: We found that BPA exposure in drinking water did not significantly alter total protein levels of ERα (Figures 6A,B) or ERβ (Figures 6C,D) in the heart during myocarditis, but significantly increased phosphorylated-ERα (p-ERα) (Figures 6A,B) and phosphorylated-ERβ (p-ERβ) (Figures 6C,D) in mice exposed to 5 μg BPA/kg BW.
