Activin and Activin Receptor Expression Changes in Liver Regeneration in Rat
Journal of Surgical Research, 2005This study aimed to investigate regulatory mechanisms of hepatocyte proliferation by comparing liver regeneration of the remnant lobe after 70% partial hepatectomy (PH) and portal vein branch ligation (PBL) in rat.Expressions of activins betaA, betaC, and betaE and their receptors were investigated after PH and PBL.

Activin, Activin-Binding Protein (Follistatin) and Activin Receptor
1993The principal regulators of the pituitary gonadotropins LH and FSH in mammals are the gonadotropin-releasing hormone (GnRH) from the hypothalamus and the gonadal steroids.

Conventional treatment regimen of lower-risk MDS with erythropoiesis-stimulating agents often fails to induce sustained erythroid improvement in these patients that frequently harbor defects in late-stage erythroblasts downstream of erythropoietin action.

Gene expression of activin, activin receptors, and follistatin in intestinal epithelial cells
American Journal of Physiology-Gastrointestinal and Liver Physiology, 2000Gene expression of activin, activin receptors, and follistatin was investigated in vivo and in vitro using semiquantitative RT-PCR in intestinal epithelial cells. Rat jejunum and the intestinal epithelial cell line IEC-6 expressed mRNA encoding the βA-subunit of activin, α-subunit of inhibin, activin receptors IB and IIA, and follistatin. An epithelial

EXPRESSION OF ACTIVIN AND ACTIVIN RECEPTORS IN PC3 HUMAN PROSTATIC-CANCER CELLS
International Journal of Oncology, 1995PC3 human prostatic cancer cells, which are androgen-independent and hormone-nonresponsive, were used to examine the possible presence and expression of activin and its receptors in this cell line because activin is a member of transforming growth factor beta (TGF beta) superfamily which has been found to have growth-inhibitory activity.

Activin A and Activin Receptors in the Human Thyroid: A Link to the Female Predominance of Goiter?
Hormone and Metabolic Research, 2000Activin A belongs to the TGF-beta family of growth factors involved in control of tissue formation by growth inhibition and to a family of hormones involved in human reproduction. Serum levels of dimeric activin A display a sexual dimorphism with significantly higher circulating hormone concentrations in men than in women after menopause.

Experimental Cell Research, 1996
Truncated activin type II receptors have been reported to inhibit activin receptor signaling in Xenopus embryos, although the mechanism of action for this effect has not been fully understood. In the present study we demonstrate that in P19 embryonal carcinoma cells both the induction of the activin responsive 3TP-lux reporter construct and the ...

Activins and the Receptor Serine Kinase Superfamily
1995Publisher Summary Inhibins and activins were discovered by virtue of their effects on the gonadotropic cells of the anterior pituitary. Inhibin/activin subunits and their mRNAs have been detected in many tissues, including the ovary, testis, placenta, pituitary, central nervous system (CNS), adrenal, and bone marrow.

Activin is a member of the TGF-beta superfamily and has various effects on diverse biological systems. Activins initiate their cellular responses by binding to their receptors with intrinsic serine/threonine kinase activity and activation of specific downstream intracellular effectors termed Smad proteins.

[Activin and activin receptors in related gynecologic and obstetric diseases].
Zhong nan da xue xue bao. Yi xue ban = Journal of Central South University. Medical sciences, 2011Activin is a member of the transforming growth factor-beta (TGF-beta) superfamily that result from the assembly of disulphide-linked betaA and betaB subunits. Activin receptors are transmembrane proteins and activin fulfils the biological function through the signal transduction of the receptor system.
