Establishment of a mouse model bearing orthotopic temozolomide-resistant glioma / 南方医科大学学报

ABSTRACT

OBJECTIVE@#To establish a mouse model bearing orthotopic temozolomide (TMZ)-resistant glioma that mimics the development of drug resistance in gliomas @*METHODS@#Seventy-eight adult C57BL/6 mice were randomly divided into 6 groups (@*RESULTS@#The mouse models bearing TMZresistant glioma was successfully established. The cells from the high-dose induced group showed a significantly higher colony-forming rate than those from the high-dose control group (@*CONCLUSIONS@#Progressive increase of TMZ doses in mice bearing orthotopic gliomas can effectively induce TMZ resistance of the gliomas.
