Study on the effect of superparamagnetic γ-Fe2O3 combined with carmustine on cervical cancer

Abstract

This study aims to investigate the killing effect of γ-Fe2O3 combined with carmustine on cervical carcinoma cells, as well as the mechanism of drug resistance of this combined treatment. RT-PCR was used to detect the expression of Multidrug Resistance Gene (MDR-l) gene in all the samples. Results showed that the combination of γ-Fe2O3 and carmustine drugs was significantly better than the control group (P < 0.05), and the tumor showed different degrees of tolerance in combination with the drug. The results of an in vitro drug sensitivity test were consistent with those of mRNA expression of MDR-l gene (P < 0.04). The combination of superparamagnetic γ-Fe2O3 and carmustine derivatives has a better therapeutic effect on cervical carcinoma than either treatment alone. The drug sensitivity test and MDR-l mRNA detection in vitro can improve the accuracy and predictability of cervical carcinoma chemotherapy, providing a scientific basis for individual tumor chemotherapy.
