To quantify whether KP-NINJA tumors were infiltrated by T cells, we performed anti-CD3 IHC staining on tumor-bearing lungs from 8-week KP-NINJA mice, and compared them with KP mice infected with Cre-GFP33 LV or non-antigenic Cre LV (full construct with promoters: Lenti-pgk-Cre). This evidence concerns the gene PRKG1 and neoplasm.
