Interestingly, SRPK2 (obtained from blood) was regulated by the highest number of PD-specific miRNAs (hsa-miR-17-3p, hsa-miR-181a-5p, hsa-miR-181b-5p, hsa-miR-181c-5p, hsa-miR-181d, hsa-miR-19a-3p and hsa-miR-19b-3p) and these seven PD-specific miRNAs are regulated by 25 lncRNAs and 16 mTFs (Table 6). This evidence concerns the gene SRPK2 and Parkinson disease.
