Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Activin in the brain modulates anxiety-related behavior and adult neurogenesis. [PDF]

PLoS ONE, 2008
Activin, a member of the transforming growth factor-beta superfamily, is an endocrine hormone that regulates differentiation and proliferation of a wide variety of cells. In the brain, activin protects neurons from ischemic damage.

15-deoxy-Δ12,14-prostaglandin J2 Down-Regulates Activin-Induced Activin Receptor, Smad, and Cytokines Expression via Suppression of NF-κB and MAPK Signaling in HepG2 Cells

PPAR Research, 2013
15-Deoxy-Δ12,14-prostaglandin J2 (15d-PGJ2) and activin are implicated in the control of apoptosis, cell proliferation, and inflammation in cells. We examined both the mechanism by which 15d-PGJ2 regulates the transcription of activin-induced activin ...

Activin, inhibin and the human breast

, 2004
Activins and inhibins are growth factors involved in cell differentiation and proliferation. Human breast tissues such as normal mammary tissue, fibroadenoma, and breast cancer express inhibin and activin mRNA and proteins.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Activin-A signaling promotes epithelial–mesenchymal transition, invasion, and metastatic growth of breast cancer

npj Breast Cancer, 2015
Background:Activins belong to the transforming growth factor-β (TGF-β) superfamily of cytokines. Although the role of TGF-β in cancer progression has been highly advocated, the role of activin signaling in cancer is not well known.

TGF‐β Inhibition Attenuates Tau Accumulation and Neurodegeneration in Progressive Supranuclear Palsy Patient‐Derived Organoids

Movement Disorders, EarlyView.
Abstract Background Progressive supranuclear palsy (PSP) is a devastating 4‐repeat tauopathy with no approved disease‐modifying treatments. Recent evidence showed increased transforming growth factor‐β (TGF‐β) levels in PSP patient‐derived ventral midbrain organoids (vMOs) and serum neuronally derived exosomes. Objective This study investigated whether

The activin-follistatin anti-inflammatory cycle is deregulated in synovial fibroblasts

Arthritis Research & Therapy, 2019
Background Activin A and follistatin exhibit immunomodulatory functions, thus affecting autoinflammatory processes as found in rheumatoid arthritis (RA).

Human Umbilical Cord Mesenchymal Stem Cell–Derived Exosomes Attenuate Renal Fibrosis by Suppressing Fibroblast Activation via the INHBA/PI3K/AKT Pathway

Pediatric Discovery, EarlyView.
MSC‐Exo derived from human umbilical cord (HucMSC‐Exo) downregulates INHBA expression, consequently modulating the PI3K/AKT signaling cascade. This regulation attenuates renal fibroblast activation and extracellular matrix deposition, thereby exerting a renoprotective effect against fibrosis.
