Mesoderm induction requires interaction between cells of the animal and vegetal hemispheres of the embryo. Several molecules have been proposed as candidates for mesoderm-inducing signals, with activin a particularly strong ...

Follistatin is an activin-binding protein produced by several tissues, including endometrium and endometriotic implants. We aimed to quantify follistatin in patients with ovarian endometriosis and investigate its value as ...

P>Skeletal muscle abnormalities can contribute to decreased exercise capacity in heart failure. Although muscle atrophy is a common alteration in heart failure, the mechanisms responsible for muscle mass reduction are not ...

Cystic ovarian disease (COD) is an important cause of infertility in dairy cattle. Although many researchers have focused their works on the endocrine changes related with this disease, there is evidence that intra-ovarian ...

Activin A is a growth factor, produced by the endometrium, whose actions are modulated by the binding protein follistatin. Both proteins are detectable in the peripheral serum and their concentrations may be increased in ...

Background Myostatin has been shown to regulate skeletal and cardiac muscle growth. However, its status on long-term hypertrophied myocardium has not been addressed. The purpose of this study was to evaluate the expression ...
