Immunostaining with Girdin antibodies confirmed the successful Girdin KO in the tumors from mice transduced with Lenti-sgTrp53-sgGirdin/Cre (Figure 1H), and all the tumors were lung adenocarcinomas, based on positive TTF1 staining (Figure 1I). The gene discussed is CCDC88A; the disease is lung adenocarcinoma.
