Estrogen and progesterone receptors in the gallbladders from patients with gallstones
Franco O. Ranelletti, Mauro Piantelli, Everardo Zanella, Arnaldo Capelli, Attilio M. Farinon – 1 October 1991 – Cytosolic receptors for estrogen and progesterone were assayed in 50 gallbladders from 29 women and 21 men who had cholecystectomies because of choleithiasis. High‐affinity (equilibrium dissociation constant, KD = 0.46 ± 0.23 nmol/L of 24 cases) estrogen receptors were detected in 20 of 29 gallbladders from women (range = 1.6 to 32 fmol/mg protein; mean ± S.D. = 10.9 ± 8.1), whereas in men only 4 of 21 specimens contained detectable estrogen receptors.
