Parkinson's Key Gene Primary · 3 days

The blood of patients were taken for genetic testing and relative expression levels of the genes(These genes expression relative to a house keeping gene:GAPDH) for PPP2CA, PPP3CB, SYNJ1, NSF were extracted.The method we used is RT-PCR.

Sponsor's own description

The research team used meta-analytical statistical methods to integrate the results of different research groups on Parkinson's disease, using meta-analysis to find key genes related to the pathogenesis and development of Parkinson's disease, and to make small clinical results. The verification of the sample, the internal mechanism of the pathogenesis of Parkinson's disease and provide guidance and reference for subsequent experimental research.
