Mitochondrial reactive oxygen species accelerate gastric cancer cell invasion.

ABSTRACT: Tumor invasion is the most important factor to decide patient's prognosis. The relation between reactive oxygen species and tumor invasion is mainly reported that nicotinamide adenine dinucleotide phosphate oxidase in the cell membrane is a reactive oxygen species producer for formulating an invadopodia. On the other hand, mitochondrion was known as one of the most important reactive oxygen species-producer in the cell via an energy transfer system. However, the relation between mitochondrial reactive oxygen species and the tumor invasion was not well clarified. In this study, we evaluated the relation between mitochondrial reactive oxygen species and tumor invasion using a normal gastric mucosal cell-line (RGM-1) and a cancerous mutant RGM-1 cell-line (RGK-1).
