Quercetin and temozolomide-loaded nanoliposomes (QUE/TMZ-NLs) exert cytotoxic effects on the temozolomide-resistant U87 glioma cells (U87/TR cells). (A) The relative colony formation rate of the U87/TR cells following treatment with TMZ at the indicated concentrations. (B) The effects of TMZ on the viability of U87 and U87/TR cells. (C) Cell death was measured by the release of LDH from the U87/TR cells. (D) Treatment with QUE/TMZ-NLs decreased the viability of the U87/TR glioma cells as measured by MTT Assay. *p<0.05, **p<0.01 and ***p<0.001 compared with the control. QUE, quercetin; TMZ, temozolomide; NLs, nanoliposomes.
