NFKB1 and glioblastoma: Due to recent reports on the anticancer potential of the endocannabinoid system, compounds 1–7 were tested against a battery of luciferase reporter gene vectors that assess the activity of many cancer-related signaling pathways, including Stat3, Smad2/3, AP-1, NF-κB, E2F, Myc, Ets, Notch, FoxO, Wnt, Hedgehog and pTK in HeLa and T98G glioblastoma cells.
