Record 3 2011-11-01

English

Subject field(s)
  • Biochemistry
  • Biotechnology
  • Cancers and Oncology
DEF

A protein secreted by transformed cells that can stimulate growth of normal cells.

CONT

A number of transforming growth factors have been isolated from media conditioned by tumor cells. Two of these were purified on the basis of their synergistic actions in stimulating the growth of fibroblasts in soft agar, an assay often used as an index of cell "transformation." Since cancer cells grow in soft agar, the growth factors were first thought to be mitogens involved in tumorigenesis and were called tumor growth factors. However their main role appear to be in embryonic development and in tissue repair.

CONT

Or Todaro et coll. avaient observé que les fibroblastes en culture, transformés par certains rétrovirus porteurs d'oncogènes, secrétaient dans le milieu de culture des substances capables d'imprimer à des cellules normales un comportement phénotypique proche de cellules transformées. Ces facteurs que l'on a appelés facteur de croissance transformant (TGF) ont été isolés et caractérisés chimiquement.

Record 4 1991-07-01

English

Subject field(s)
  • Cytology
CONT

Transforming growth factor alpha in arterioles: cell surface processing of its precursor by elastases.

OBS

Tiré de: Molecular and cellular biology, 1990, 10 (9), 4596-4602.

French

Domaine(s)
  • Cytologie
CONT

Le TGF a qui présente une forte homologie avec l'epidermal growth factor stimule l'angiogénèse in vivo et est mitogène pour les cellules endothéliales. Le TGF B entraîne in vivo, après injection sous-cutanée, une accumulation de macrophages, de fibroblastes et de collagène; et induit une néovascularisation. En revanche, in vitro, il inhibe la croissance des cellules endothéliales. Son activité angiogénique in vivo met donc probablement en jeu les macrophages.
