Comparative Solution Equilibrium Studies on Anticancer Estradiol-Based Conjugates and Their Copper Complexes

open access: yesInorganics
Steroids are often considered valuable molecular tools for the development of anticancer agents with improved pharmacological properties. Conjugation of metal chelating moieties with a lipophilic sterane backbone is a viable option to obtain novel ...

Synthesis and properties of some new 3-substituted hexestrol derivatives

open access: yes, 1987
A series of new monosubstituted hexestrol derivatives were synthesized and the estrogenic and cytotoxic properties of some of them were studied. 3-Acetoxymethyl-hexestrol 8 has a binding affinity for the cytoplasmic estrogen receptor as high as estradiol.

WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

open access: yesAdvanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

open access: yesAdvanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.

Exploring biomarkers of neurodegenerative risk: associations of oxysterols, sex hormones, and reproductive characteristics in older women

open access: yesJournal of Lipid Research
Women face a higher lifetime risk of developing neurodegenerative diseases such as Alzheimer’s disease and related dementias. The menopausal transition, characterized by a decline in estrogen levels, may affect cholesterol metabolism and ...

LncRNA FLJ20021 Restrains Fibroblast Senescence and Matrix Remodeling in Pelvic Organ Prolapse by Promoting XRCC6‐Dependent ADI1 Transcription

open access: yesAdvanced Science, EarlyView.
FLJ20021 interacts with XRCC6 to regulate ADI1 transcription and downstream cellular phenotypes in hUSLFs. Reduced FLJ20021 in POP is associated with lower ADI1, increased apoptosis, senescence, and an ECM‐degrading marker profile. Conversely, FLJ20021 overexpression enhances XRCC6‐dependent ADI1 expression, reduces apoptosis and senescence, and shifts

Plasma Membrane Lipid Asymmetry Dynamically Regulates Passive Diffusion

open access: yesAdvanced Science, EarlyView.
Passive diffusion enables hydrophobic molecules to cross the plasma membrane and exert their biological functions. This study demonstrates that plasma membrane lipid asymmetry, dynamically regulated by lipid scrambling, determines membrane permeability to lipophilic molecules and thereby modulates their cellular activities.

LncRNA HAND2OT encoding micropeptide regulates the estradiol secretion, proliferation and apoptosis of ovarian follicular theca cells in chickens

open access: yesPoultry Science
Long non-coding RNAs (lncRNAs) are critical regulators of ovarian follicular development. In chicken ovarian follicles, theca cells are primarily responsible for androgen and estradiol biosynthesis and play an important role in chicken follicular ...

Synthesis of substituted 15β-alkoxy estrone derivatives and their cofactor-dependent inhibitory effect on 17β-HSD1

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) is a key enzyme in the biosynthesis of 17β-estradiol. Novel estrone-based compounds bearing various 15β-oxa-linked substituents and hydroxy, methoxy, benzyloxy, and sulfamate groups in position C3 as ...
