Relative mRNA expression of estrogen receptor (ER). Panel A: mRNA expression of ESR1 (ERα), ERβ (ESR2), and the balance of ESR1:ESR2 in abdominal subcutaneous adipose tissue (SAT); Panel B: mRNA expression of ESR1, ESR2, and the balance of ESR1:ESR2 in femoral SAT from premenopausal (n=23) and postmenopausal (n=22) women. * p<0.05, † p=0.05 for pre-vs post-menopausal women.
