Figure 2. Effects of radio-induced IFITM3 expression on BTPCs.

A, B. and C. Fractionized IR of 1080 cells led to an increased expression of IFITM3 (A) mRNA and protein as detected by (B) Western blot or (C) immunocytochemistry. TCL - total cell lysate. Scale bar represents 20 μm. D. rs1080 cells displayed enhanced sphere-forming capacity as compared to the parental cell line 1080. E. Survival potential of rs1080 and the parental control 1080 48 h after increasing doses of γ-radiation. F. Immunostainings showing stabile upregulation of IFITM3 in rs1080 tumors. Scale bar represents 50 μm. G. Kaplan-Meier survival curves of mice with rs1080 and control tumors.
