To use human erythroleukemia drug resistant cell line K562/A02 as an experimental model, to research the effect of TSPG on the drug resistance of K562/A02 cell line and its mechanism.
Methods: The sensitivity of untreated and TSPG-treated K562/A02 cells to anticancer drugs was determined by MTT assay. Immunohistochemistry method was used to measure mdr-1 gene product P-gp and bcl-2 protein expression. RT-PCR technique was used to examine mdr-1 mRNA expression.
Results: (1) TSPG inhibi...
