Epidemiology studies of human workers exposed to particulate cobalt have found increased incidence of lung cancer. A hallmark of lung cancer, chromosome instability(CIN) manifests as either numerical or structural abnormalities, which are thought to result from unrepaired or miss-repaired DNA double strand breaks, homologous recombination (HR) and non homologous end joining (NHEJ). Previous studies have shown that HR protects cells against metal induced CIN while NHEJ does not. We investigated whether this outcome occurs for cobalt.
