Characterization of Activin A-, Activin-AB and Activin-B-Responding Cells by Their Responses to Hypothalamic Releasing Hormones

Biochemical and Biophysical Research Communications, 1994
Activin A-, AB- and B-responding cells were characterized by their responsiveness in cytosolic free calcium ([Ca2+])i) to four hypothalamic releasing hormones, CRH, GHRH, TRH and GnRH. First, rat pituitary cells responding to activin A, AB and B in [Ca2+]i were determined in a mixed population of pituitary cells. The populations of the activin A-, AB-,

The yin and yang of Activin A

Blood, 2011
In this issue of Blood , Sierra-Filardi and colleagues shed new light on the still poorly understood proinflammatory role of Activin A in macrophage polarization ...

Quantitative two-site enzyme-linked immunosorbent assays for inhibin A, activin A and activin B

Human Reproduction, 1993
We have developed three specific enzyme-linked immunosorbent assay (ELISA) formats which quantitate inhibin A in conditioned media and serum. The assays are sensitive in a range 0.078-5.0 ng/ml and have been characterized in terms of cross-reactivity to inhibin related proteins. The CK:CK assay format recognizes inhibin A, inhibin B and inhibin-related

ACTIVIN AND ACTIVIN RECEPTORS IN A RAT OSTEOGENIC-SARCOMA CELL-LINE, UMR-106

International Journal of Oncology, 1995
We have localized immunocytochemically activin-A-like reactivity in UMR-106 osteogenic cells with a characterized, specific antiserum against synthetic fragment of subunits of activin-A, a member of transforming growth factor B (TGFB) superfamily.

Activin A and hepatocyte growth regulation

Hepatology, 1994
The present study was conducted to examine the effect of activin A on growth of rat hepatocytes. EGF induced a 10-fold increase in DNA synthesis as assessed by [3H]thymidine incorporation in cultured hepatocytes. When activin A was added together with EGF, DNA synthesis induced by EGF was markedly inhibited.

Activin is a nerve cell survival molecule

Nature, 1990
The structures of five neurotrophic molecules have so far been published. Nerve growth factor, fibroblast growth factor and purpurin, have been identified as nerve-cell survival molecules. More recently, brain-derived neurotrophic factor (BDNF) and ciliary neurotrophic factor have been cloned and sequenced.

Concentration-dependent inducing activity of activin A

Roux's Archives of Developmental Biology, 1991
Human recombinant activin A, which is identical with erythroid differentiation factor (EDF), was tested for its mesoderm-inducing activity in concentrations from 0.3-50 ng/ml, using ectoderm of Xenopus late blastula (Stage 9) as the responding tissue.

Activin A and follistatin in systemic inflammation

Molecular and Cellular Endocrinology, 2004
Inflammation is a complex process regulated by a cascade of cytokines and growth factors. This review summarizes the emerging evidence implicating activin A and follistatin in the inflammatory process. Our recent studies have highlighted that activin A is released early in the process as part of the circulatory cytokine cascade during acute systemic ...

Demonstration of Activin-A in Arteriosclerotic Lesions

Biochemical and Biophysical Research Communications, 1994
We previously reported that follistatin, an activin-binding protein, is produced in arteriosclerotic lesions. Here, the expression of activin-A which promotes the growth of vascular smooth muscle cells was examined in arteriosclerotic lesions of WHHL (Watanabe heritable hyperlipidemic) rabbits.

Immunohistochemical Detection of Activin A in Osteoclasts

Gerontology, 1996
Production of a member of transforming growth factor-beta (TGF-beta) superfamily, activin A, was examined in the bone tissue by using reverse transcriptase polymerase reaction. As a result, specific bands were detected showing the presence of activin A mRNA in the bone tissues.
