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 ...

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 ...

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 ...

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 Biosynthesis and Signal Transduction in Ovarian Disease

open access: yesFrontiers in Endocrinology, 2022
Estrogen mainly binds to estrogen receptors (ERs) to regulate menstrual cycles and reproduction. The expression of ERalpha (ERα), ERbeta (ERβ), and G-protein-coupled estrogen receptor (GPER) mRNA could be detected in ovary, suggesting that they play an ...

Enhanced Resistance to Tamoxifen by the c-ABL Proto-oncogene in Breast Cancer

open access: yesNeoplasia: An International Journal for Oncology Research, 2010
Targeting the estrogen receptor is an important strategy in breast cancer therapy. However, although inhibiting estrogen receptor function with specific estrogen receptor modulators can achieve a primary response in cancer patients, intrinsic or ...
