Abstract:
Objective To discuss the effect of QGY/CDDP hepatoma lines multi-drug resistance (MDR) reversed by gene transfection of mdr1,mrp-ASODN+ultrasound contrast agent+ultrasound.Methods The QGY/CDDP cells were transfected by mdr1,mrp ASODN+ultrasound contrast agent+ultrasound irradiation respectively and detected of the various indicators:cell adhesion rate,cell sensitivity to cell drug-resistance,the mRNA expression of mdr1 and mrp gene,the expression of P-gp and MRP protein. Results After mdr1-ASODN transfection,the drug sensitivity and expression of P-gp,MRP protein of QGY/CDDP cells were smaller changes(P＞0.05),and the rate of cells adherent and expression of resistance gene mRNA were obvious changes(P＜0.05).After mrp-ASODN transfection,the cells adherent rate,the drug sensitivity,the expression of resistance gene mRNA and P-gp,MRP protein were obvious changes respectively(P＜0.05),the experiment group(group 2')had bigger effects(P＜0.05).Conclusions mdr1. mrp-ASODN+ultrasound contrast agent+ultrasound irradiation could safely partly reverse MDR of hepatoma cells,which is a potential new approach for gene therapy.
