Cell viability of (A) 9L gliosarcoma cells and (B) primary rat astrocytes, treated with different concentrations of DNA nanoparticles for a period of 24 h. Flow cytometric analysis of DNA nanoparticle cellular uptake in (C) 9L gliosarcoma cells and (D) primary rat astrocytes. Luciferase gene expression reported as RLU/mg of protein of (E) 9L cells and (F) primary rat astrocytes. Data represents mean ± SEM. *Denotes statistical significance p < 0.05.
