Fig. 5From: Human U87 glioblastoma cells with stemness features display enhanced sensitivity to natural killer cell cytotoxicity through altered expression of NKG2D ligandQuantification of NKG2D ligands in serum U87 and NBE U87 GBM cells. a ULBP1 and ULBP3 mRNA was increased in NBE U87 GBM cells. Increase of FAS mRNA was not statistical significant. b ULBP1 and ULBP3 protein expression was also enhanced. Bar graphs show the mean ± the standard error of the mean (SEM).
