English

Subject field(s)
  • Biochemistry
CONT

Activin, a member of the transforming growth factor-beta family of peptides, is implicated in the regulation of cell growth and differentiation in a variety of biological systems. We have sought to identify immediate early genes whose altered expression may provide a common nuclear event involved in activin-regulated phenotypic changes in many cell types. In both human K562 myelogenous leukemia and rat PC12 pheochromocytoma cells, activin treatment caused transient transcription-dependent and protein synthesis-independent increases of junB messenger RNA(mRNA) within 1 hour...

Activin A not only stimulates the synthesis and release of pituitary follicle-stimulating hormones but exerts various effects on haematopoietic cells, embryos, and fibroblasts [Source: PASCAL database].

Surgical biopsies from 10 head and neck squamous cell carcinomas were labeled in vitro with bromodeoxyuridine. In histological sections, bromodeoxyuridine-positive nuclei and beta-fibroblast growth factor(beta-FGF) were stained using immunohistochemistry. In clearly discernible clusters of tumor cells, the cytoplasm shows strong positive beta-FGF staining, whereas other tumor regions are completely beta-FGF negative... Three classes of mesoderm-inducing factor(MIF) that might be responsible for... interaction in vivo... These are members of the transforming growth factor type beta(TGF-beta), fibroblast growth factor(FGF) and Wnt families... Six well-characterized human growth factors were chosen for detailed investigation by topical application to standardized skin wounds in swine : epidermal growth factor(EGF), transforming growth factors alpha and beta(TGF-alpha and TGF-beta), fibroblast growth factor(FGF), insulin-like growth factor-1(IGF-l), and platelet-derived growth factor(PDGf).

Recently, several mesoderm-inducing factors(MIFs) have been discovered. These cause isolated Xenopus animal caps to form mesodermal cell types such as muscle, instead of their normal fate of epidermis. The MIFs fall into two classes. One comprises members of the fibroblast growth factor(FGF) family, and the other members of the transforming growth factor type beta(TGF-beta) family. Of the latter group, the most potent is XTC-MIF, a protein produced by Xenopus XTC cells. Here we show that XTC-MIF is the homologue of mammalian activin A.
