Genetic Predisposition to Parkinson’s Disease and Cancer
Parkinson’s disease (PD) and cancer are often thought of as two sides of the same coin. At first glance, cancer
and PD appear to have little in common. PD is caused by the degeneration of dopaminergic neurons, whereas cancer
results from the uninhibited growth of tumor cells. Increasing numbers of genetic studies suggest that the pathogenesis of
PD and cancer may involve similar genes, pathways, and mechanisms. The differences in the pathological and cellular
mechanisms, and the associated genetic mutations, may result in two such divergent diseases. In this article, we highlight
some molecular mechanisms and key biomarkers which might cause those two diseases from misfolding and degradation
of proteins, mitochondrial damage, oxidative stress response, cell cycle control and DNA repair, and the PI3K/AKT/
mTOR pathway, in order to provide help to the understanding and treatment of these two diseases.
