(A, B) Determination of survival fraction and IC50 of radiation and TMZ in parental T98G, radiation-resistant T98G RR, TMZ-resistant T98G TMZR, T98G RR Fli-1 shRNA and T98G TMZR Fli-1 shRNA cells. (C) Phase contrast microscopy images of parental T98G, radiation-resistant T98G RR, TMZ-resistant T98G TMZR, T98G RR Fli-1 shRNA and T98G TMZR Fli-1 shRNA cells. T98G RR Fli-1 shRNA and T98G TMZR Fli-1 shRNA cells showing absence of long cellular extensions (EMT-like traits) similar to T98G cells. (D) Wound-healing assay evaluating migratory potential of parental T98G, radiation-resistant T98G RR, TMZ-resistant T98G TMZR, T98G RR Fli-1 shRNA and T98G TMZR Fli-1 shRNA cells. (E, F) Western blotting analysis of Fli-1, HSPB1, MMP-2, MMP-9 and EMT proteins in parental T98G, radiation-resistant T98G RR, TMZ-resistant T98G TMZR, T98G RR Fli-1 shRNA and T98G TMZR Fli-1 shRNA cells. Densitometry plot of (E, F) is in Supplementary Figure 7A and 7B. During contrast adjustments of certain blots in panels e and f, background removal occurred.
