Western blotting for ESR1 was performed as reported previously [26 (link)] on d100 control (n = 4) and Foxg1Cre/+; ARfl/y (n = 4) pituitaries. Blots were probed with primary antibodies ESR1 (Santa Cruz sc-542) and tyrosinated TUBA (α-tubulin) isoforms (Abcam ab6160). Primary antibodies were detected using donkey anti-rabbit IRDye 680RD and goat anti-rat IRDye 800CW (LI-COR Biosciences). Detection was carried out using the LI-COR Odyssey imaging system (LI-COR biosciences) according to manufacturer’s instructions.
