ERβ	0.19 ± 0.07	1.13 ± 0.35	0.16 ± 0.10	1.63 ± 0.12c

Abbreviations: COMT, catechol-O-methyltransferase; CYP1A1, cytochrome P450, family 1, subfamily A; CYP1B1, cytochrome P450, family 1, subfamily B; ERα, estrogen receptor α; ND, not detectable; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; SEM, standard error of the mean.

^a Data normalized to GAPDH are expressed as mean ± SEM (P ≤ .05, n = 3).

^b Differs from each other within each individual cell line.

^c Differs from other cell lines.
