Several lines of evidence link Alzheimer's disease (AD) to atherosclerosis (CVD), including that elevated low density lipoprotein (LDL)-cholesterol is a common risk factor. Development of genomic instability could also link the two diseases. Previous fluorescence in situ hybridization (FISH) analyses revealed a clonal expansion of aneuploid smooth muscle cells underlying atherosclerotic plaques. Likewise, cellular and mouse models of AD revealed tau-dependent mitotic defects and subsequent aneuploidy partly resulting from amyloid-beta (A&beta) interference with microtubule (MT) stability, and specific MT motors function. Moreover, AD patients develop aneuploid/hyperploid cells in brain and peripheral tissues, implicating similar mechanism that may lead to apoptosis …
