一般說明
The TGFB1 gene is mapped to human chromosome 19q13.2 and codes for a 25 kDa peptide.[1][2] TGF-ß1 polypeptide is produced as a precursor with hydrophobic signal sequence, pro-region and mature peptide. Cleavage of the precursor at tetrabasic cleavage site results in monomers of carboxy-terminal 112 amino acids. The biologically active form of Tgfb1 exists as a disulphide-linked homodimer.[3]
應用
Transforming Growth Factor-β1 (TGF-β) human has been used :
- to study the expression of PDGFRB (Platelet derived growth factor receptor β) in association with transforming growth factor-β signaling.[4]
- to stimulate lung fibrosis in human fetal lung fibroblast cell line in order to further measure the in-plane elasticity of live cell layers using a pressure sensor embedded microfluidic device.[5]
- to study the effect of TGF-β on HTRA1 (high-temperature requirement A1)-affected Wnt target genes.[6]
生化／生理作用
转化生长因子-β1 (TGF-β1)由多种细胞合成，但据报道，其含量在哺乳动物血小板中最丰富，约为TGF-β2浓度的四倍。
TGF-β1 is a multifunctional peptide capable of influencing cell proliferation, differentiation, and other functions in a wide range of cell types.[2] Transformed as well as non-neoplastic tissues release transforming growth factors and essentially all cells possess a specific TGF-β1 receptor. In general, cells of mesenchymal origin appear to be stimulated by TGF-β1; whereas, hepatocytes, T and B lymphocytes, keratinocytes, and many epithelial cells are inhibited by the peptide. TGF-β1 interacts with Epidermal Growth Factor (EGF), Platelet Derived Growth Factor (PDGF), Fibroblast Growth Factor (FGF), and T Cell Growth Factor (T-CGF) either by enhancing or antagonizing their characteristic actions. TGF-β1 plays a fundamental role in tissue growth and differentiation by involvement in adipogenesis, myogenesis, chondrogenesis, osteogenesis, epithelial cell differentiation, and immune cell function.[7] TGF-β1 is associated with the developmental and metastasis of colorectal cancer.[8]

Kidney failure (KF) is associated with cardiac fibrosis and significantly increased mortality in heart failure. Thrombospondin-1 (TSP1), a key regulator of latent transforming growth factor-β1 (L-TGF-β1) activation, is a predicted target of miR-221. We hypothesized miR-221 attenuates severe KF-associated cardiac
