Cyclopia extracts act as selective estrogen receptor subtype downregulators in estrogen receptor positive breast cancer cell lines: Comparison to standard of care breast cancer endocrine therapies and a selective estrogen receptor agonist and antagonist

open access: yesFrontiers in Pharmacology, 2023
Breast cancer is the most diagnosed type of cancer amongst women in economically developing countries and globally. Most breast cancers express estrogen receptor alpha (ERα) and are categorized as positive (ER+) breast cancer. Endocrine therapies such as,

Significance of G Protein-Coupled Estrogen Receptor in the Pathophysiology of Irritable Bowel Syndrome, Inflammatory Bowel Diseases and Colorectal Cancer

open access: yesFrontiers in Endocrinology, 2020
The regulatory role of estrogens and nuclear estrogen receptors, i. e., estrogen receptor α and β has been reported in gastrointestinal diseases. However, the contribution of G protein-coupled estrogen receptor, the membrane-bound estrogen receptor, is ...

Role of estrogen receptors in cancer: a special emphasis on the therapeutic potential of estrogen receptor β [PDF]

open access: yesPharmaceutical Sciences Asia, 2022
Estrogen receptors are nuclear receptors that play a major role in both physiology and pathology. Estrogen receptor subtypes are currently divided into three groups: estrogen receptor alpha (ERα), estrogen receptor beta (ERβ), and G protein-coupled ...

The rate of estrogen receptor‐conversion associated with tumor progression in estrogen receptor‐positive breast cancer patients following adjuvant Tamoxifen administration

open access: yesCancer Reports, 2022
Background Hormone Receptor (HR)‐discordance between primary breast cancer and metastasis is a known biological phenomenon. Discordance studies usually comprise a heterogeneous group of HR‐positive and negative patients and allow for the comparison of ...

PARP7 and Mono-ADP-Ribosylation Negatively Regulate Estrogen Receptor α Signaling in Human Breast Cancer Cells

open access: yesCells, 2021
ADP-ribosylation is a post-translational protein modification catalyzed by a family of proteins known as poly-ADP-ribose polymerases. PARP7 (TIPARP; ARTD14) is a mono-ADP-ribosyltransferase involved in several cellular processes, including responses to ...

Estrogen Signaling via Estrogen Receptor β [PDF]

open access: yesJournal of Biological Chemistry, 2010
Estrogens act by binding to and activating two estrogen receptors (ERs), ERα and ERβ. Transcriptional regulation by ERs is controlled by a complex array of factors such as ER-ligand binding, the DNA sequence bound by ERs, ER-interacting cofactors, and chromatin context.

Regenerating Rat Liver: Correlations Between Estrogen Receptor Localization and Deoxyribonucleic Acid Synthesis [PDF]

open access: yes, 1984
Estrogen receptor activity was quantitated in the cytosol and nucleus of normal rat liver and in regenerating rat liver at several time intervals after 75% hepatectomy. Cytosolic estradiol binding in regenerating liver decreases at 12, 24, and 48 h after

Estrogen, Estrogen Receptor and Lung Cancer [PDF]

open access: yesInternational Journal of Molecular Sciences, 2017
Estrogen has been postulated as a contributor for lung cancer development and progression. We reviewed the current knowledge about the expression and prognostic implications of the estrogen receptors (ER) in lung cancer, the effect and signaling pathway of estrogen on lung cancer, the hormone replacement therapy and lung cancer risk and survival, the ...
