In order to explore the modification of genes involved in the regulation of m6 modification, the research group first analyzed two sets of data in the Gene Expression Omnibus (GEO, http://www.ncbi.nlm.nih.gov/geo/) [12] database and found that heterogeneous nuclear ribonucleoprotein C (HNRNPC), as a key gene recognized by m6A modification, was significantly downregulated in PD. This evidence concerns the gene HNRNPC and Parkinson disease.
