Is alpha-Synuclein gene duplication present in sporadic Parkinson disease?
SNCA multiplication is present in sporadic Parkinson disease (PD) and needs to be screened. Low penetrance, clinical heterogeneity, and normal dopamine transporter imaging in asymptomatic carriers may suggest the presence of other genetic modifiers or environmental triggers that play a role in the pathogenesis of PD due to SNCA duplication.
The baseline secretion of IL-8 from normal prostate epithelial cells in culture is strongly correlated with cancer aggressiveness and may drive prostate cancer carcinogenesis. A better characterization of individual prostate microenvironment may provide a basis for personalized treatment and for monitoring the effects of strategies aimed at preventing aggressive prostate cancer.
