Abstract:
Objective To explore the relation between changes in apurinic/apyrimidinic endonuclease (APE1) gene expression and effects of melphalan on multiple myeloma (MM) cells. Methods Expression of APE1 protein was detected in MM cell line KM3 using immunocytochemical staining and Western blot assay after 0~15?mol/L melphalan treatment for 1~2d. Integral optical density was determined by means of image analysis system. Results There was positive relationship between levels of APE1 protein in KM3 cells and the treatment time and dose of melphalan. Conclusion Expression of APE1 protein could be induced by melphalan treatment. The result suggests that a high expression of APE1 protein may play a certain role in the resistance of multiple myeloma to melphalan.
