There are 4 (PTK6, CDK1, AURKA and EPHB2) and 10 kinases (PAK1, PKMYT1, AURKB, CHEK1, CDK1, JAK3, EPHB2, PRKCG, PTK6 and AURKA) of the Hannover‐AD and TCGA cohort whose gene expression and kinase activities were upregulated in the same way. This evidence concerns the gene EPHB2 and Alzheimer disease.
