The role of effectors of the activin signalling pathway, activin receptors IIA and IIB, and Smad2, in patterning of tooth development

open access: yes, 2001
The gene for activin betaA is expressed in the early odontogenic mesenchyme of all murine teeth but mutant mice show a patterning defect where incisors and mandibular molars fail to develop but maxillary molars develop normally.

Activin A in Mammalian Physiology [PDF]

open access: yesPhysiological Reviews, 2019
Activins are dimeric glycoproteins belonging to the transforming growth factor beta superfamily and resulting from the assembly of two beta subunits, which may also be combined with alpha subunits to form inhibins. Activins were discovered in 1986 following the isolation of inhibins from porcine follicular fluid, and were characterized as ovarian ...

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

open access: yesBMEMat, 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.

235. Activin C antagonises activin A in vitro and over-expression leads to prostate pathologies in vivo

open access: yes, 2008
Activin A is a well characterised inhibitor of proliferation in most epithelial cells. The actions of activin A on cell growth are mediated through Smad-dependent pathways. Activin A is potent at low levels, therefore its synthesis and bioactivity must

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC 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, inhibin and the human breast

open access: yes, 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.

Activin promotes skin carcinogenesis by attraction and reprogramming of macrophages

open access: yesEMBO Molecular Medicine, 2016
Activin has emerged as an important player in different types of cancer, but the underlying mechanisms are largely unknown. We show here that activin overexpression is an early event in murine and human skin tumorigenesis. This is functionally important,

Activin and follistatin in female reproduction.

open access: yes, 2004
Activin and follistatin were initially identified in the follicular fluid based on their effects on pituitary FSH secretion in the mid-1980s. It is now evident that activin, follistatin and activin receptors are widely expressed in many tissues where ...

Activin A plays an essential role in migration and proliferation of hepatic stellate cells via Smad3 and calcium signaling

open access: yesScientific Reports
Activin A and hepatic stellate cells (HSCs) are involved in tissue repair and fibrosis in liver injury. This study investigated the impact of activin A on HSC activation and migration.

Activin and Hepatocyte Growth Factor Promotes Colorectal Cancer Stemness and Metastasis through FOXM1/SOX2/CXCR4 Signaling

open access: yesGut and Liver
Background/Aims: Cancer stem cells (CSCs) are believed to drive tumor development and metastasis. Activin and hepatocyte growth factor (HGF) are important cytokines with the ability to induce cancer stemness.
