Blood Cell‐Camouflaged Liquid Metal Nanoconjugates Orchestrate Treg Depletion and STING‐Amplified Photothermal Immunity for Metastatic Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Whole‐blood biomimetic engineering transforms liquid metal nanoparticles into a tripartite immunotherapeutic platform that orchestrates regulatory T‐cell depletion, photothermal‐induced immunogenic cell death, and activation of the stimulator of interferon genes pathway.

Cancer‐Associated Fibroblasts Promote Glucose Metabolic Reprogramming and Progression of Triple‐Negative Breast Cancer via Exosomal circFAD104‐Mediated Intercellular Communication

Advanced Science, EarlyView.
CAF‐derived exosomes deliver circFAD104 into TNBC cells, where it acts as a molecular scaffold that bridges the E3 ligase MARCHF8 and PGM1, promoting MARCHF8‐mediated K48‐linked ubiquitination and proteasomal degradation of PGM1. Loss of PGM1 redirects glucose‐phosphate flux from glycogen synthesis toward glycolysis, thereby driving stemness, EMT, and ...

Progesterone and Follicle Stimulating Hormone interact and promote goat preantral follicles survival and development in vitro

Pesquisa Veterinária Brasileira, 2012
We investigated the effects of progesterone and follicle stimulating hormone (FSH) on survival and growth of caprine preantral follicles. Pieces of ovarian tissue were cultured for 1 or 7 days in minimum essential medium (MEM) alone or containing ...

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

Effects of Levonorgestrel and progesterone on Oviductal physiology in mammals

Reproductive Biology and Endocrinology, 2018
Background Our previous study indicated that emergency contraception, including levonorgestrel and progesterone, could lead to ectopic pregnancy following contraception failure. However, our understanding of the effects of levonorgestrel and progesterone

Epigenetic Reactivation of TNFRSF19 Suppresses Mitophagy and Sensitizes Triple‐Negative Breast Cancer to Doxorubicin

Advanced Science, EarlyView.
TNFRSF19 is an epigenetically silenced regulator of mitophagy in triple‐negative breast cancer. TNFRSF19 deficiency activates the TGFBR1–SMAD3–PINK1 axis to promote mitophagy and confer doxorubicin resistance, whereas decitabine‐mediated restoration of TNFRSF19 suppresses mitophagy and enhances doxorubicin sensitivity, revealing a targetable epigenetic–

PRMT1, un nouveau corégulateur de la signalisation de la progestérone dans le cancer du sein

, 2019
Breast cancer progression is mainly driven by estrogen and progesterone signalling and therapies modulating oestrogen‘s action have improved the survival of ER+ cancer patients. As progesterone receptor (PR) is an ER target gene, its expression in breast

Hypothalamic effects of progesterone on regulation of the pulsatile and surge release of luteinising hormone in female rats

Scientific Reports, 2017
Progesterone can block the oestradiol-induced GnRH/LH surge and inhibit LH pulse frequency. Recent studies reported that progesterone prevented premature LH surges during ovarian hyperstimulation in women. As the most potent stimulator of GnRH/LH release,

Les ligands modulateurs du récepteur de la progestérone (PRMs) (mécanismes d'action et applications thérapeutiques)

, 2006
La progestérone est une hormone stéroïde ayant un rôle fondamental pour la fonction reproductive chez la femme. Elle agit essentiellement en se fixant sur un récepteur nucléaire.
