In this study, we found that exposure to 5 μg BPA/kg BW decreased the mRNA expression of ERα in the heart during CVB3 myocarditis (p = 0.02) and increased the expression of ERβ (p = 0.04), but had no significant effect on ERRγ (p = 0.38) or the androgen receptor (AR) (p = 0.91) (Figure 5B, Table 4). Here, ESR1 is linked to myocarditis.
