Progesterone receptors in nuclei and cytosols from the hypothalamus and anterior
hypophysis of oestrogen-primed immature and mature female rats were investigated. In the …

Progesterone-binding components were detected in hypothalamic and anterior hypophysial
cytosols from estrogen-primed immature and mature female rats. These components were …

Specific progesterone receptor of 7S which can be isolated from rat female hypothalamic
and hypophysial cytosols was further investigated in terms of its induction effects by …

Rat uterine nuclei containing unlabelled progesterone–receptor complexes were incubated
at 0° C with the synthetic progestogen [3 H] R5020 (17, 21-dimethyl-19-norpregna-4, 9 …

The aim of this study was to examine the role of sex steroid hormones in the regulation of
intracellular progesterone receptors (PR) in the rabbit central nervous system. We …

Cytosol prepared from rat brains perfused with saline possesses saturable macromolecular
components which form unstable complexes with [3 H] progesterone in vitro. The …

The transfer of guinea pig uterine progesterone receptors from cytosol to nuclei, in cell-free
incubations, was studied using an exchange method to measure receptors. In order to …

A synthetic progestin, 16α-ethyl-21-hydroxy-19-nor-4-pregnene-3, 20-dione (ORG 2058),
was utilized to measure progesterone receptors from the rabbit uterus. This steroid has a …

A synthetic progestin, R5020, was used to identify cytoplasmic progestin receptors in the
hypothalamuspreoptic area (HPOA) of ovariectomized mice. These high-affinity receptors …

The distribution of progesterone receptors between cytosol and nuclear fractions of guinea-
pig uterus was determined after the injection of 1 mg/kg and 10 mg/kg progesterone. After …
