| Research Abstract |
Oxaliplatin-based chemotherapy in patients with colorecatl liver metastases has been shown to be significantly associated with sinusoidal obstruction syndrome (SOS). In the present study, our proteomics study using 2-Dimensional electrophoresis and LC/MS/MS showed that Peroxiredoxin6、Aldehyde dehydrogenase 2、 α-methylacetyl-CoA racemase、Protein disulfide-isomerase A3、60-S-acid ribosomal protein P0、and Glutathione S-transferase M1 (GST-M1) significantly differed as compared with the control sinusoidal cells. Among them, GST-M1 significantly decreased in human sinusoidal endothelial cells after the administration of oxaliplatin. In addition, an administration of sphingosine 1 phosphate (S1P), which has a protective effect on sinusoidal endothelial injury, significantly attenuate the oxaliplatin-induced sinusoidal injury and showed the maintenance of GST-M1 concentration. These results suggests thatGST-M1 and S1P have a crucial role of oxaliplatin-induced sinusoidal endothelial inj.
