Analysis of Oct4-dependent transcriptional networks regulating self-renewal and pluripotency in human embryonic stem cells [PDF]

, 2006
The POU domain transcription factor OCT4 is a key regulator of pluripotency in the early mammalian embryo and is highly expressed in the inner cell mass of the blastocyst. Consistent with its essential role in maintaining pluripotency, Oct4 expression is

Activin A promotes neuronal differentiation of cerebrocortical neural progenitor cells. [PDF]

PLoS ONE, 2012
BACKGROUND: Activin A is a protein that participates principally in reproductive functions. In the adult brain, Activin is neuroprotective, but its role in brain development is still elusive.

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-A Induces Fewer, but Larger Osteoclasts From Monocytes in Both Healthy Controls and Fibrodysplasia Ossificans Progressiva Patients

Frontiers in Endocrinology, 2020
Fibrodysplasia Ossificans Progressiva (FOP) is a rare genetic disease characterized by heterotopic ossification (HO) that occurs in muscle tissue, tendons, and ligaments.

Alveolar macrophages of GM-CSF knockout mice exhibit mixed M1 and M2 phenotypes [PDF]

, 2013
Background Activin A is a pleiotrophic regulatory cytokine, the ablation of which is neonatal lethal. Healthy human alveolar macrophages (AMs) constitutively express activin A, but AMs of patients with pulmonary alveolar proteinosis (PAP) are ...

Inhibin interferes with activin signaling at the level of the activin receptor complex in Chinese hamster ovary cells [PDF]

, 1997
To gain more insight in the mechanism of action of inhibin, we studied the effect of inhibin on activin signaling in Chinese hamster ovary cells.

Human activin-A is expressed in the atherosclerotic lesion and promotes the contractile phenotype of smooth muscle cells [PDF]

, 1999
Activin is a member of the transforming growth factor-beta superfamily, and it modulates the proliferation and differentiation of various target cells. In this study, we investigated the role of activin in the initiation and progression

Potential role of kisspeptin in the estradiol-induced modulation of inhibin subunit gene expression: Insights from in vivo rat models and hypothalamic cell models

Endocrine Journal
The hypothalamic-pituitary-gonadal (HPG) axis is primarily regulated by kisspeptin neurons. In addition, activin and inhibin within the central nervous system might contribute to the regulation of the HPG axis because they are expressed near kisspeptin ...

Clinical Implication of Targeting of Cancer Stem Cells [PDF]

, 2012
The existence of cancer stem cells (CSCs) is receiving increasing interest particularly due to its potential ability to enter clinical routine. Rapid advances in the CSC field have provided evidence for the development of more reliable anticancer ...
