TGF-β receptor inhibitor LY2109761 enhances the radiosensitivity of gastric cancer by inactivating the TGF-β/SMAD4 signaling pathway

Figure 6. Effect of LY with or without irradiation on the expression of p-Smad2 and CSC markers in GC cell lines. (A) Immunofluorescence assay: representative results of the p-Smad2 expressions in GC cells after LY with or without irradiation treatment. (B) Flow cytometry analysis: the representative results of the expressions of the putative stem cell markers CD24 and CD133 in GC cells with or without LY and irradiation treatment.
