Furthermore, we determined that T0901317 administration inhibited growth of inoculated LLC1 tumors in C57BL/6 wild type mice but not mice lacking IFN-γ expression (IFN-γ−/−, C57BL/6 background) which indicates that the inhibition of tumor growth by T0901317 is dependent, at least in part, on the activation of IFN-γ production. The gene discussed is IFNG; the disease is neoplasm.
