Zn-curc reactivates mtp53 in an orthotopic U373 glioblastoma model. (A) U373MG-LUC cells (2.5x105) were injected into the brain of athymic mice and left to growth for 6 days before treating animals with Zn-curc every day for 7 days. Mock- or Zn-curc-treated U373M-derived tumors were then harvested and analysed with a fluorescent microscope that showed as diffuse fluorescence only in Zn-curc- treated tumors. (B) Quantification of tumor cell fluorescence positivity in U373-derived tumors, untreated or Zn-curc-treated, ±SD. (C) Total mRNA was extracted from harvested U373-derived tumors, untreated or Zn-curc-treated, and p53 target gene expression as well as VEGF, MDR1 and Bcl2 expression were assayed by PCR of reverse-transcribed cDNA. Gene expression was measured by densitometry and plotted as fold of mRNA expression over control (Mock), normalized to β-actin levels, ±SD.
