Possible significance of degeneration and decreased expression of progesterone receptor in postmenopausal uterine leiomyoma

BMC Women's Health, 2022
Background The growth of uterine leiomyomas is dependent on the levels of sex steroid hormones, and they usually shrink after menopause. However, there are cases in which leiomyomas continue to grow and/or surgery is required after menopause. In addition

Stimuli‐Responsive CuFeTe2 Nanosheets for Amplified Cuproptosis/Ferroptosis in Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Dual‐stimuli‐responsive CuFeTe2 nanosheets (CFT) induce cuproptosis/ferroptosis via TME‐responsive Fe2⁺/Cu2⁺ release and NIR‐II photothermal effects, amplifying ROS and depleting HSP70/ATP to trigger ICD and immune activation, while ensuring biocompatible renal clearance for TNBC therapy.

Estrogen Receptor Positive/Progesterone Receptor Negative Breast Carcinomas: A Subgroup Deserves Particular Interest

Bezmiâlem Science, 2015
Objective:Breast carcinomas positive for the estrogen receptor (ER+) but negative for the progesterone receptor (PR−) have unfavorable prognostic features and are resistant to tamoxifen therapy. The goal of this study was to highlight the significance of

Investigating Estrogen and Progesterone Receptors in the Lacrimal Sacs of Individuals With and Without Chronic Dacryocystitis

Beyoglu Eye Journal, 2019
INTRODUCTION[|]Chronic dacryocystitis is usually seen in middle-aged or older women, suggesting that decreased estrogen and progesterone serum levels may be a causative factor in the disease pathology.

Intrahepatic Cholestasis of Pregnancy Levels of Sulfated Progesterone Metabolites Inhibit Farnesoid X Receptor Resulting in a Cholestatic Phenotype

Hepatology, 2013
Intrahepatic cholestasis of pregnancy (ICP) is the most prevalent pregnancy‐specific liver disease and is associated with an increased risk of adverse fetal outcomes, including preterm labor and intrauterine death.

Interferon‐Driven Biomarkers and Synergistic Therapy for PRMT5 Inhibition in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Triple‐negative breast cancer exhibits variable sensitivity to PRMT5 inhibition. Basal interferon signaling is identified as a key biomarker of response. PARP inhibition with olaparib induces IFN signaling, sensitizing resistant TNBC cells to PRMT5 inhibitors.

Progestins Inhibit Interleukin-1β-Induced Matrix Metalloproteinase 1 and Interleukin 8 Expression via the Glucocorticoid Receptor in Primary Human Amnion Mesenchymal Cells

Frontiers in Physiology, 2020
Preterm premature rupture of membranes is a leading cause of preterm births. Cytokine induced matrix metalloproteinase1 and interleukin 8 production from amnion mesenchymal cells may contribute to fetal membrane weakening and rupture.

Hepatic KLF9 Deficiency Inhibits Dehydroepiandrosterone (DHEA)‐Induced Polycystic Ovary Syndrome via Liver‐Ovary Axis

Advanced Science, EarlyView.
The study shows that liver is a previously unrecognized extraovarian organ that plays a key role about androgen homeostasis in the development of DHEA‐induced PCOS. DHEA is the most common precursor of active androgen, such as DHT, and KLF9 is required for the conversion of DHEA to DHT and hepatic KLF9 might be a potential therapeutic target for PCOS ...

Clinical association of progesterone receptor isoform A with breast cancer metastasis consistent with its unique mechanistic role in preclinical models

BMC Cancer, 2020
Background Luminal breast cancer (L-BCa) comprises the majority of incurable, distally metastatic breast cancer cases. Estrogen supports growth of L-BCa cells but suppresses invasiveness. Estrogen also induces the progesterone receptor (PR). Invasiveness

Dienogest increases the progesterone receptor isoform B/A ratio in patients with ovarian endometriosis

Journal of Ovarian Research, 2012
BackgroundThe resistance of endometriotic tissue to progesterone can be explained by alterations in the distribution of progesterone receptor (PR) and estrogen receptor (ER) isoforms.
