MiRNA expression profiling in Parkinson disease patients from Heavy metal exposer and non exposer group with respective control

Peripheral blood samples were collected from (Heavy metal exposer- Parkinson disease)HME-PD, (Heavy metal non-exposer- Parkinson disease) NHME-PD, and healthy controls. Total RNA was isolated and profiled using the Affymetrix GeneChip™ miRNA 3.1 Array. Arrays were hybridized, washed, stained, scanned, and raw data (.CEL files) were RMA-normalized for differential expression.
