Concerted action of human chorionic gonadotropin and norepinephrine on intracellular-free calcium in human granulosa-lutein cells [PDF]

open access: yes, 1993
Luteal cells are known to possess receptors for LH/hCG and receptors of the beta-adrenergic type. Interactions of specific agonists with either receptor lead to the activation of adenylate cyclase and subsequently to an increase of cAMP.

Efficacy of Fractional Laser on Steroid Receptors in GSM Patients

open access: yesBioengineering, 2023
Background: To compare the efficacy of CO2 fractional laser with that of topical estriol for treating genitourinary syndrome of menopause and to investigate the relationship between epithelial thickness and vaginal atrophy.

17,β-estradiol inhibits hepatitis C virus mainly by interference with the release phase of its life cycle [PDF]

open access: yes, 2016
Rationale & Aim: Estrogen and estrogen-mediated signalling protect from hepatitis C virus through incompletely understood mechanisms. We aimed to ascertain which phase(s) of HCV life cycle is/are affected by estrogens.

Role for growth regulation by estrogen in breast cancer 1 (GREB1) in hormone-dependent cancers [PDF]

open access: yes, 2018
Sex hormones play important roles in the onset and progression of several cancers, such as breast, ovarian, and prostate cancer. Although drugs targeting sex hormone function are useful in treating cancer, tumors often develop resistance.

Placental weight and mortality in premenopausal breast cancer by tumor characteristics [PDF]

open access: yes, 2012
Placental weight may be regarded as an indirect marker of hormone exposures during pregnancy. There is epidemiological evidence that breast cancer mortality in premenopausal women increases with placental weight in the most recent pregnancy.

Physiological Action of Progesterone in the Nonhuman Primate Oviduct

open access: yesCells, 2022
Therapies that target progesterone action hold potential as contraceptives and in managing gynecological disorders. Recent literature reviews describe the role of steroid hormones in regulating the mammalian oviduct and document that estrogen is required

Hormone Receptor Status in Breast Cancer and its Relation to Age and Other Prognostic Factors

open access: yesBreast Cancer: Basic and Clinical Research, 2011
Background Increasing evidence shows the importance of young age, estrogen receptor (ER), progesterone receptor (PR) status, and HER-2 expression in patients with breast cancers.

Short oestrous cycles in sheep during anoestrus involve defects in progesterone biosynthesis and luteal neovascularisation [PDF]

open access: yes, 2014
Anoestrous ewes can be induced to ovulate by the socio-sexual, 'ram effect'. However, in some ewes the induced ovulation is followed by an abnormally short luteal phase causing a so called, "short cycle".

Progesterone receptors, their isoforms and progesterone regulated transcription [PDF]

open access: yesMolecular and Cellular Endocrinology, 2012
This review discusses mechanisms by which progesterone receptors (PR) regulate transcription. We examine available data in different species and tissues regarding: (1) regulation of PR levels; and (2) expression profiling of progestin-regulated genes by total PRs, or their PRA and PRB isoforms.

Genomic sequence analyses of classical and non-classical lamprey progesterone receptor genes and the inference of homologous gene evolution in metazoans

open access: yesBMC Evolutionary Biology, 2019
Background Nuclear progesterone receptor (nPR) is an evolutionary innovation in vertebrates that mediates genomic responses to progesterone. Vertebrates also respond to progesterone via membrane progesterone receptors (mPRs) or membrane associated ...
