There was a non-significant trend towards delayed tumor growth in FAP KO mice receiving anti-βgal T cells compared to tolerized T cells from vaccinated FAP KO animals (Fig 6Fi-ii, closed circle vs closed triangle, p = 0.09), which also failed to demonstrate a survival difference (Fig 6G, closed circle vs closed triangle, median survival 42.5 days vs 48.5 days). This evidence concerns the gene FAP and neoplasm.
