Cadmium cation increases the production and mRNA levels of insulin-like growth factor-binding protein-1 in HepG2

Biosci Biotechnol Biochem. 2007 May;71(5):1334-7. doi: 10.1271/bbb.60679. Epub 2007 May 7.

Abstract

The production of insulin-like growth factor-binding protein-1 (IGFBP-1) in HepG2 was increased by cadmium cation (Cd2+) at 3 microM, but not by other divalent cations. The mRNA level of IGFBP-1 was also increased by the administration of 3 microM of Cd(2+). These results suggest that Cd(2+) impacts the gene expression of IGFBP-1, which leads to production of IGFBP-1.
