In the ASCs, the portions of tumors consisting of AD cells also exhibited the same marker expression of SCC cells (p63 and CK5) in Lkb1d/d (Supplementary Fig. 1g), in Lkb1d/dPtend/d (Supplementary Fig. 3e) and in Lkb1d/dJnk1d/dJnk2−/− (Fig. 4d) mice. This evidence concerns the gene KRT5 and Alzheimer disease.
