Inhibitive Effects of Lipoic Acid on the DNA-protein Crosslink Induced by Formaldehyde in Mice Liver
To explore the relation between oxidative stress and DNA-protein crosslink formation caused by formaldehyde (FA) inhalation in mice liver. Methods: 15 Kun Ming mice were divided into 3 groups: control group, 3.0 mg/m3 gaseous FA inhaled group, 3.0 mg/m3 gaseous FA and lipoic acid (LA) treated group. The content of reduced glutathione (GSH) and the content of DPC were measured after the treatment for 3d. Results: The content of GSH in liver cells declined significantly and the content of DPC increased significantly after inhaled with 3.0 mg/m3 gaseous FA. The content of GSH and DPC were both recovered to control group after treated with 3.0 mg/m3 gaseous FA inhalation and LA injection. Conclusion: LA injection could inhibit the formation of DPC in mice liver after exposure to FA. It is suggested that DPC formation in mice liver may be related with oxidative damage.
