Estrogens play a crucial role in the regulation of the physiology of breast tissue and endometrium. Furthermore, estrogen has been implicated in the initiation and progression of neoplasms of these tissues. Estrogens mediate their effects through various estrogen receptor isoforms and isotypes. In breast tissue and in the endometrium the classical estrogen receptor ERalpha represents the mainly expressed ER isoform, whereas in the ovary the alternative estrogen receptor ERbeta is predominantly expressed. This review briefly describes the structure, function and expression of these receptors with special regard to endometrial cancer. Recent data indicate that alterations of the physiological ERalpha/ERbeta ratio in endometrial cancer correlates with poor clinical outcome. The potential clinical relevance of differential ER-isotype expression is also discussed with respect to an antihormonal therapy.

Introduction: Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that affects various body systems, including the skin and facial features. Estrogen promotes lupus in human and mouse models of SLE. In this study, we conducted an in vivo study to investigate the relationship between two estrogen receptors (ERα and ERβ) and platelet-activating factor acetylhydrolase (PAF-AH) on the symptoms of SLE.

Oral selective estrogen receptor degraders (SERDs) are pure estrogen receptor antagonists that have the potential to overcome common resistance mechanisms to endocrine therapy in estrogen receptor-positive breast cancer. There are currently five oral SERDs in published and ongoing clinical trials-elacestrant, camizestrant, giredestrant, imlunestrant, and amcenestrant-with more in development. They offer a reasonably well-tolerated oral therapy option with low discontinuation rates in studies.

Purpose: Individuals with metastatic breast cancer (MBC) may live with their disease for many years. We initiated the Johns Hopkins Hope at Hopkins Clinic to assess the needs and optimize the care of these patients.
Patients And Methods: Patients with MBC who agreed to participate in the Clinic in addition to usual care completed patient-reported outcome (PRO) surveys.
Invasive Lobular Carcinoma (ILC), a distinct subtype of breast cancer is hallmarked by E-Cadherin loss, slow proliferation, and strong hormone receptor positivity. ILC faces significant challenges in clinical management due to advanced stage at diagnosis, late recurrence, and development of resistance to endocrine therapy - a cornerstone of ILC treatment. To elucidate the mechanisms underlying endocrine resistance in ILC, ILC cell lines (MDA-MB-134-VI, SUM44PE) were generated to be resistant to tamoxifen, a selective estrogen receptor modulator.

Estrogen receptor β (ERβ) is aberrantly expressed in castration-resistant prostate cancer (CRPC). Therefore, a diagnostic and therapeutic ERβ probe not only helps to reveal the complex role of ERβ in prostate cancer (PCa), but also promotes ERβ-targeted PCa therapy. Herein, we reported a novel ERβ-targeted near-infrared fluorescent probe D3 with both imaging and therapeutic functions, which had the advantages of high ERβ selectivity, good optical performance, and strong anti-interference ability.
