Figure 3. Estrogen receptor alpha (ESR1) expression in guinea pig uteri during late pregnancy.

Figure 3

A, Representative immunoblot pictures showing ESR1 protein and GAPDH loading control in one representative uterine sample of the gestational stage groups 45d, 55dA, 55dB and 62d. The T47D cell extract is positive control. Duplicates containing 60 µg protein were run from each uterine extract. B, ESR1 protein relative abundance determined by densitometry. Variance is not significantly different among the gestational stage groups. C, ESR1 mRNA relative abundance in guinea pig uteri at late gestation. Variance is not significantly different among the gestational stage groups (n = 6–8 per group).
