1 High glucose-induced proliferation in mesangial cells is reversed by autocrine TGF-beta. Glucose transforming growth factor, beta 1 Mus musculus
2 Several lines of evidence indicated that the late phase of glucose-induced growth inhibition was mediated by the bioactivation of endogenous transforming growth factor beta (TGF-beta). Glucose transforming growth factor, beta 1 Mus musculus
3 Neutralizing antibody against TGF-beta prevented the late inhibitory effects of glucose on proliferation. Glucose transforming growth factor, beta 1 Mus musculus
4 Furthermore, Northern blot analysis revealed that TGF-beta 1 mRNA was induced by 450 mg/dl glucose in the medium after 48 to 72 hours, but not after 24 hours. Glucose transforming growth factor, beta 1 Mus musculus
5 However, the addition of neutralizing anti-TGF-beta antibody stimulated the progression of cells towards S-G2 in high glucose medium after 48 hours. Glucose transforming growth factor, beta 1 Mus musculus
6 This inhibition may be mediated by the glucose-induced synthesis and/or bioactivation of TGF-beta which can inhibit proliferation of mesangial cells in an autocrine fashion. Glucose transforming growth factor, beta 1 Mus musculus
