Transforming Growth Factor Beta-1 (TGF-beta1) Transgenic Mouse Model

Posted Aug 16 2010 5:00pm

Description of Invention:
Transforming Growth Factor-beta1 (TGF-beta1) is a multifunctional cytokine that is involved in many physiological processes such as immune regulation, cell proliferation, angiogenesis, apoptosis, and extracellular matrix deposition. Overexpression of activated TGF-beta1 signaling pathway is known to play a role in many disease processes, such as inflammation, fibrosis and tumor metastasis.

NIH inventors have developed a transgenic mouse model, designated beta1glo, which permits conditional, gene-specific overexpression of TGF-beta1. The model features a TGF-beta1 transgene for which expression is blocked by a floxed enhanced green fluorescent protein (EGFP) gene downstream of the promoter. Excision of the EGFP gene by Cre recombinase allows expression of TGF-beta1. Thus, these mice may be cross-bred with a variety of Cre transgenic mouse lines in order to study the role of TGF-beta1 in targeted organ systems and tissues.
