|||
|---|---|---|---|---|
| Vehicle | EST | Vehicle | EST | |
| NaPi-IIc | 100 ± 3.0 | 92 ± 4.0 | 100 ± 13 | 97 ± 10 |
| Pit2 | 100 ± 4.5 | 106 ± 4.0 | 100 ± 6.0 | 100 ± 10 |
| Pit1 | 100 ± 5.0 | 98 ± 5.0 | ND | ND |
Data are expressed as means ± SE; n = 4 rats in each group. Ovariectomized (OVX) rats were treated with estrogen (EST; 15 μg/100 g body weight) or vehicle for 3 days. The mRNA and protein expression of Pi transporters were examined with Northern hybridization and immunoblotting, respectively.
