Both vanadium and chromium are two common toxic metals. Accumulating evidence indicates that exposure of humans to either metal induces a wide spectrum of adverse effects, including carcinogencity. neurotoxicity. and immunotoxicity. Among these adverse effects, carcinogencity is the major geological consequence. The underlying molecular mechanisms have not been fully identified yet. For the past several years, much attention has been focused on how these two metals alter cellular signal transduction to lead to carcinogenesis. This chapter will serve as a summary of recent advances in the knowledge base for cellular signal transduction, including induction of tyrosine phosphorylation. phosphatidylinositol 3-kinase (PI3 kinase) signaling, nuclear factor-kB (NF-kB) activation, cell cycle arrest, and apoptosis,in response to vanadium or chrominum.
