Anti-activin A Antibody (IgY) Specifically Neutralizes Various Activin A Activities
Experimental Biology and Medicine, 1996 Activin A (beta A beta A), originally isolated from ovarian follicular fluids as a follicule-stimulating hormone (FSH) secretion stimulator, has also been identified as an erythroid differentiation factor (EDF), a neuron survival factor and a mesoderm-inducing factor. Thus, activin A is a multifunctional factor, and further studies on its physiological

Activin A and Betacellulin [PDF]
Diabetes, 2004 Activin A and betacellulin (BTC) are thought to regulate differentiation of pancreatic β-cells during development and regeneration of β-cells in adults. In the present study, we used neonatal rats treated with streptozotocin (STZ) to investigate the effects of activin A and BTC on regeneration of pancreatic β-cells. One-day-old Sprague-Dawley rats were

The Impact of Activin A on Fetal Gonocytes: Chronic Versus Acute Exposure Outcomes
Frontiers in Endocrinology, 2022 Activin A, a TGFβ superfamily member, is important for normal testis development through its actions on Sertoli cell development. Our analyses of altered activin A mouse models indicated gonocyte abnormalities, implicating activin A as a key determinant ...

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 ...

Effect of Activin A on In Vitro Development of Rat Preantral Follicles and Localization of Activin A and Activin Receptor II [PDF]
Biology of Reproduction, 2001 Preantral follicles (140-160 microm) were isolated mechanically from the ovaries of 10-day-old rats and cultured in groups of four to six for 6 days in medium containing 0, 1, 10, or 100 ng/ml of activin A. Activin stimulated (P < 0.05) the growth of preantral follicles in a dose-dependent fashion and enhanced the proliferation of preantral, oocyte ...
