Figure 3. Agonists of ERα, ERβ, and GPR30 promoted ERK activation in TM-BBB cells.

Figure 3

(A) RT-PCR analysis demonstrating the presence of transcripts of M3 muscarinic receptor (226 bp), M5 muscarinic receptor (230 bp), ERα estrogen receptor (453 bp), ERβ estrogen receptor (204 bp) and GPR30 estrogen receptor (386 bp) in TM-BBB cells. (B) TM-BBB cells were stimulated with the estrogen receptor agonists, PPT (ERα), DPN (ERβ), or G1 (GPR30) for 60 min, and cell lysates were analyzed by western blotting with anti-pERK or anti-total ERK antibodies.
