Watanabe H, Adachi R, Hirayama A, Kasahara T, Suzuki K: Triphenyltin enhances the neutrophilic differentiation of promyelocytic HL-60 cells. Biochem Biophys Res Commun. 2003 Jun 20;306(1):26-31.
At a low concentration, 10 (-7) M, TPT increased superoxide production by differentiated HL-60 cells stimulated with opsonized zymosan (OZ) by about 45% and increased expression of CD18, a component of the OZ-receptor, by about 90%.
Real-time PCR analysis revealed that TPT augmented the expression not only of CD18 but also of components of superoxide-generating NADPH-oxidase, p47phox, 2.7-fold, and p67phox, 2.0-fold, and of granulocyte colony-stimulating factor receptor (G-CSFR), 3.0-fold, whereas various other endocrine disruptors, including parathion, vinclozolin, and bisphenol A, had no such enhancing effects. |
