IFNG and neoplasm: We examined whether IFN-γ participates in AT-101 sensitized tumor cell killing by ATC and aATC, by staining for intracellular IFN-γ in ATC and aATC, and by measuring IFN-γ in culture supernatant after 4 h co-culture with L3.6pl and MiaPaCa-2 cells either pre-sensitized with AT-101 or left untreated.
