The degree centrality for each protein listed in the Fig 5 is equal to or greater than the mean of degree centrality, thus, APP, LRP1, UBC, YWHAE, EGFR, ELAVL1, YWHAB, YWHAZ, SUMO1, SRC, and EGR1 are essential shared proteins, in which APP and LRP1 are also causative genes related AD. This evidence concerns the gene YWHAB and Alzheimer disease.
