Fig. 2. AF treatment increases doxorubicin uptake in GBM xenografts.
(A) Mice xenografted with GBM43 cells were given a combination of doxorubicin (Dox) and SPC diet or nasal AF. (B–D) Doxorubicin (red) and DAPI (blue) in tumors 20 min after tail-vein injection of doxorubicin. Scale bar: 40 μm. (E) Quantification of fluorescence (red) shows increased uptake of doxorubicin in tumor tissues of mice treated with SPC diet or nasal AF (n=3, **P < 0.01, one-way ANOVA). Kaplan-Meier (n=6 for control, n=5 for AF, and n=9 for SPC, **P < 0.01, ***P < 0.001; one-way ANOVA for control v/s AF and SPC, respectively) curve showing survival benefit following combination treatments with doxorubicin and SPC diet or nasal AF.
