Activin A and Activin Receptors in Thyroid Cancer

Thyroid, 2001
Proliferation is controlled by a network of mitogenic and growth inhibitory factors. Transforming growth factor-beta1 (TGF-beta1) and activin A are the most important growth inhibitors of benign follicular epithelial cells of the human thyroid. The effects of these substances on malignant primary thyrocytes are not known.

Bovine preantral follicles and activin: Immunohistochemistry for activin and activin receptor and the effect of bovine activin a in vitro

Theriogenology, 1997
Activin was originally isolated from follicular fluid as a factor stimulating FSH from the pituitary. Recent studies also suggest a local role for activin in the development of preantral and early antral follicles. In the present study, activin and activin receptor immunoreactivity are shown in oocyte and granulosa cells of bovine preantral follicles ...

Activin A In Brain Injury

2007
Activin A is a growth factor composed of two betaA subunits belonging to the transforming growth factor beta (TGF-beta) superfamily of dimeric proteins. The biological activity of activin A is mediated by two different types of receptors, the type I (ARI and ARIB) and the type II receptors (ARII and ARIIB), and by two activin-binding proteins ...
