Others have proposed links between neurodegeneration/cancer and cell cycle regulation, DNA repair, response to oxidative stress [72,106], aberrant wingless and proto-oncogene Int-1 (Wnt) signaling [107], glycogen synthase kinase 3-beta (GSK3β) regulation [108], modulation of tumor protein 53 (TP53 or P53) expression [109], and perturbations of tau in AD and prostate cancer [110]. This evidence concerns the gene TP53 and Familial prostate cancer.
