An autocrine ActivinB mechanism drives TGFβ/Activin signaling in Group 3 medulloblastoma

EMBO Molecular Medicine, 2019
Medulloblastoma (MB) is a pediatric tumor of the cerebellum divided into four groups. Group 3 is of bad prognosis and remains poorly characterized. While the current treatment involving surgery, radiotherapy, and chemotherapy often fails, no alternative ...

ACTIVIN RECEPTOR LIGAND FOR THR TREATMENT OF BETA-THALASSEMIA: a SERENDIPITOUS DISCOVERY

Mediterranean Journal of Hematology and Infectious Diseases, 2020
b-thalassemia is a hereditary disorder caused by defective production of b-globin chains of hemoglobin (Hb) that leads to an increased a/b globins ratio with subsequent free a-globins.

Epigenetic Regulation of Liver Fibrosis: Mechanisms and Therapeutic Implications

Portal Hypertension &Cirrhosis, EarlyView.
This review synthesizes the epigenetic mechanisms—DNA methylation, histone modifications, and non‐coding RNAs—that drive hepatic stellate cell activation and the progression of liver fibrosis. It further evaluates emerging therapeutic strategies targeting these epigenetic regulators, including DNA methyltransferase and histone deacetylase inhibitors ...

A Label‐Free Ultraviolet Photoacoustic Microscopy Enables Nuclear Imaging and Toxicity Assessment in an Intact Brain Organoid

Small, EarlyView.
Ultraviolet photoacoustic microscopy enables label‐free visualization of nuclear morphology in intact human brain organoids. By exploiting endogenous nucleic acid absorption at 266 nm, this approach resolves individual nuclei without staining or sectioning.

Phthalate Metabolite, Mono(2‐Ethyl‐5‐Hydroxyhexyl) Phthalate (MEHHP), Promotes Uterine‐Fibroid–Associated Phenotypes in Myometrial Stem Cell‐Derived 3D Organoids

Environmental Toxicology, EarlyView.
ABSTRACT This study investigates how phthalate exposure contributes to uterine fibroid (UF) development by studying the effects of the Mono‐(2‐ethyl‐5‐hydroxyhexyl) phthalate (MEHHP), a metabolite of Di(2‐ethylhexyl) phthalate, on myometrial stem cells (MMSCs).

Vactosertib, a Novel, Orally Bioavailable Activin Receptor-Like Kinase 5 Inhibitor, Promotes Regression of Fibrotic Plaques in a Rat Model of Peyronie’s Disease

The World Journal of Men's Health, 2020
Purpose: To examine the therapeutic effect of Vactosertib, a small molecule inhibitor of transforming growth factor-β (TGF-β) type I receptor (activin receptor-like kinase-5, ALK5), in an experimental model of Peyronie’s disease (PD) and determining ...

Avoiding pitfalls when modelling ligands in macromolecular crystallography

Acta Crystallographica Section D, EarlyView.
Flawed protein–ligand X‐ray structures can misdirect drug discovery based on PDB‐deposited models. This review uses publicly available PDB examples to highlight potential pitfalls, from absent ligands to incorrect chemistry, and presents a practical validation approach to improve model reliability.The determination of protein–ligand complex structures ...

Expression and distribution of activin-follistatin-inhibin axis in the urinary bladder

Frontiers in Molecular Biosciences
The activin-follistatin-inhibin (AFI) axis plays a crucial role in sexual development and reproduction. Recently it was demonstrated that these proteins are also synthesized by many local tissues and regulate different biological activities, including ...

Supraphysiologic Administration of GDF11 Induces Cachexia in Part by Upregulating GDF15

Cell Reports, 2018
Summary: The age-related effects of GDF11 have been a subject of controversy. Here, we find that elevated GDF11 causes signs of cachexia in mice: reduced food intake, body weight, and muscle mass.
