The orphan ligand, activin C, signals through activin receptor-like kinase 7

eLife, 2022
Activin ligands are formed from two disulfide-linked inhibin β (Inhβ) subunit chains. They exist as homodimeric proteins, as in the case of activin A (ActA; InhβA/InhβA) or activin C (ActC; InhβC/InhβC), or as heterodimers, as with activin AC (ActAC ...

Myostatin/Activin-A Signaling in the Vessel Wall and Vascular Calcification

Cells, 2021
A current hypothesis is that transforming growth factor-β signaling ligands, such as activin-A and myostatin, play a role in vascular damage in atherosclerosis and chronic kidney disease (CKD).

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

Hepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Activin A and activin receptors in gestational tissue from preeclamptic pregnancies [PDF]

Journal of Endocrinology, 2001
Maternal serum activin A levels are elevated in women with preeclampsia. To explore whether this could be due, at least in part, to increased production by the gestational tissues, we have measured activin A in the serum of women with (n=23) or without preeclampsia (n=62) at 29-40 weeks of gestation and in placenta and fetal membranes from preterm ...

ALK1 controls hepatic vessel formation, angiodiversity, and angiocrine functions in hereditary hemorrhagic telangiectasia of the liver

Hepatology, EarlyView., 2022
Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Activins and Activin Receptors in Cell Growth

Experimental Biology and Medicine, 1997
Activin and inhibin, members of transforming growth factor-beta (TGFbeta) superfamily, have diverse and widespread effects within living organisms at many stages during growth and development. From the initial isolation of these growth factors based on their effects of FSH secretion, the study of these factors, as well as of the activin-binding protein

Activin receptor-like kinase-2 inhibits activin signaling by blocking the binding of activin to its type II receptor [PDF]

Journal of Endocrinology, 2007
Activin receptor-like kinase-2 (Alk2) has been shown to be a promiscuous type I receptor for the transforming growth factor β (TGFβ) family of growth and differentiation factors, such as activin, bone morphogenetic proteins, and Müllerian inhibiting substance (MIS).

Acute Modulation of Synaptic Plasticity of Pyramidal Neurons by Activin in Adult Hippocampus

Frontiers in Neural Circuits, 2014
Activin A is known as a neuroprotective factor produced upon acute excitotoxic injury of the hippocampus (in pathological states). We attempt to reveal the role of activin as a neuromodulator in the adult male hippocampus under physiological conditions ...

Lefty blocks a subset of TGFbeta signals by antagonizing EGF-CFC coreceptors. [PDF]

PLoS Biology, 2004
Members of the EGF-CFC family play essential roles in embryonic development and have been implicated in tumorigenesis. The TGFbeta signals Nodal and Vg1/GDF1, but not Activin, require EGF-CFC coreceptors to activate Activin receptors.

Activin B can signal through both ALK4 and ALK7 in gonadotrope cells

Reproductive Biology and Endocrinology, 2006
Background Activins stimulate pituitary FSH synthesis via transcriptional regulation of the FSHbeta subunit gene (Fshb). Like other members of the TGFbeta superfamily, these ligands signal through complexes of type I and type II receptor serine/threonine
