Human cells (A549-lung carcinoma) and bat cells from Pteropus vampyrus (PVK4- kidney fibroblast) or Eidolon helvum (ZFBK13-75A- kidney fibroblast) were transfected with low-molecular weight poly(I:C), a double-stranded RNA mimic, to stimulate IFN induction. This evidence concerns the gene IFNA1 and lung carcinoma.
