Targeting myostatin/activin A protects against skeletal muscle and bone loss during spaceflight

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Among the major health challenges for astronauts during prolonged space travel are loss of muscle mass and loss of bone mass. Here, we investigated the effects of targeting the signaling pathway mediated by the secreted signaling molecules ...

Activin B promotes the initiation and progression of liver fibrosis

open access: yesHepatology Communications, 2022
The role of activin B, a transforming growth factor β (TGFβ) superfamily cytokine, in liver health and disease is largely unknown. We aimed to investigate whether activin B modulates liver fibrogenesis.

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

open access: yesJournal 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 ...

Activin A forms a non-signaling complex with ACVR1 and type II Activin/BMP receptors via its finger 2 tip loop

open access: yeseLife, 2020
Activin A functions in BMP signaling in two ways: it either engages ACVR1B to activate Smad2/3 signaling or binds ACVR1 to form a non-signaling complex (NSC).

Cripto forms a complex with activin and type II activin receptors and can block activin signaling [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
Activin, nodal, Vg1, and growth and differentiation factor 1 are members of the transforming growth factor β superfamily and signal via the activin type II (ActRII/IIB) and type I (ALK4) serine/threonine kinase receptors. Unlike activins, however, signaling by nodal, Vg1, and growth and differentiation factor 1 requires a coreceptor from the epidermal ...

Effect of activin A on migration and adhesion of breast cancer 4T1 cells

open access: yesZhongguo gonggong weisheng, 2023
ObjectiveTo explore the effect of activin A on the migration and adhesion of murine breast cancer 4T1 cells. MethodsThe viability of in vitro cultured 4T1 cells was studied using the 3- (4,5-dimethyl-2-thiazyl)-2,5-diphenyl-2h-tetrazolium bromide (MTT ...

An Activin-A/C Chimera Exhibits Activin and Myostatin Antagonistic Properties [PDF]

open access: yesJournal of Biological Chemistry, 2005
Activins are involved in many physiological and pathological processes and, like other members of the transforming growth factor-beta superfamily, signal via type II and I receptor serine kinases. Ligand residues involved in type II receptor binding are located in the two anti-parallel beta strands of the TGF-beta proteins, also known as the fingers ...

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

open access: yesHepatology, 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 ...

Role of stromal activin A in human pancreatic cancer and metastasis in mice

open access: yesScientific Reports, 2021
Pancreatic ductal adenocarcinoma (PDAC) has extensive stromal involvement and remains one of the cancers with the highest mortality rates. Activin A has been implicated in colon cancer and its stroma but its role in the stroma of PDAC has not been ...

A paracrine activin A–mDia2 axis promotes squamous carcinogenesis via fibroblast reprogramming

open access: yesEMBO Molecular Medicine, 2020
Cancer‐associated fibroblasts (CAFs) are key regulators of tumorigenesis and promising targets for next‐generation therapies. We discovered that cancer cell‐derived activin A reprograms fibroblasts into pro‐tumorigenic CAFs.
