Did you mean Estrogen Receptors?

Glossary Estrogen Receptors

proteins that bind estrogen, influencing cell behavior and function

Estrogen receptors (ER) are proteins found inside and on the surface of certain cells that bind to the hormone estrogen. When estrogen binds to these receptors, it can influence the behavior of the cell, including growth, differentiation, and function. These receptors play a crucial role in various physiological processes, including reproductive health, bone density, and even hair growth. In medical research, ERs are significant in understanding conditions like breast cancer, where the presence of these receptors can influence treatment options.

research The oestrogen receptor 2 (ESR2) gene in female-pattern hair loss: replication of association with rs10137185 in German patients

4 citations , December 2013 in “British Journal of Dermatology”

This study reports an association between the ESR2 gene variant rs10137185 and female-pattern hair loss in German patients.

research Combined oral contraceptives promote androgen receptor and oestrogen receptor alpha upregulation in the female prostate (Skene’s paraurethral glands) of adult gerbils (Meriones unguiculatus)

3 citations , January 2018 in “Reproduction, Fertility and Development”

This study concluded that cyproterone acetate alone produced antiandrogenic effects on the female gerbil prostate, while ethinyloestradiol alone stimulated estrogenic activity, and their combination led to prostatic lesions.

research 17β-Estradiol Inhibits Wound Healing in Male Mice via Estrogen Receptor-α

38 citations , May 2010 in “American Journal Of Pathology”

In this study, prolonged systemic administration of 17β-estradiol in castrated male mice delayed wound healing by inhibiting re-epithelialization and reducing collagen accumulation, with estrogen receptor-α likely mediating this effect.

research Polyamine Oxidase Expression Is Downregulated by 17β-Estradiol via Estrogen Receptor 2 in Human MCF-7 Breast Cancer Cells

8 citations , July 2022 in “International Journal of Molecular Sciences”

This study found that in estrogen receptor-positive breast cancer cells, 17β-estradiol repressed polyamine oxidase transcription by interacting with AP-1 sites on its promoter.

research Patient-Reported Outcomes From Phase III Neoadjuvant Systemic Trial Comparing Neoadjuvant Chemotherapy With Neoadjuvant Endocrine Therapy in Pre-Menopausal Patients With Estrogen Receptor-Positive and HER2-Negative, Lymph Node-Positive Breast Cancer

1 citations , July 2021 in “Frontiers in Oncology”

This study found that patient-reported outcomes were similar between neoadjuvant endocrine therapy and chemotherapy in premenopausal breast cancer patients, but future perspective was significantly better with endocrine therapy.

community Theaflavin (Black Tea Extract) reduce DHT, androgen receptor activity and estrogen

6 upvotes 3 years ago

Theaflavin, a black tea extract, may inhibit DHT and androgen receptor activity, but its effectiveness for hair loss is debated. Users report no significant improvement with theaflavin, while some find beta sitosterol helpful.

community Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?

in Treatment 44 upvotes 2 years ago

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

community Having androgen receptor density and sensitivity at wrong f*ing place

in Satire 7 upvotes 1 year ago

The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.

community Has anyone powered through the creatine shedding (via increased androgen receptor sensitivity) and stabilized?

9 upvotes 1 year ago

Creatine may cause increased hair shedding due to androgen receptor sensitivity, despite limited evidence. The user is using dutasteride and minoxidil and seeks advice on whether shedding will stabilize, with suggestions including GHK-Cu and RU58841.

community Alternatives/unorthodox hairloss protocols to the big three

in Chat 1 upvotes 8 months ago

The conversation discusses alternative and unorthodox hair loss treatments, including RU58841, nandrolone, and dianabol, as well as theoretical approaches involving high doses of estrogen and selective estrogen receptor modulators. These methods are considered extreme and potentially harmful but are explored for those unable to tolerate traditional 5-alpha reductase inhibitors.
