In a “Single Search” application on AD (tissue, brain; p-value threshold, 0.005), we had miRDRN construct a partial RRN (Gene filter, BACE1; Show top 70 sub-pathways; Network layout, Radial) centered on BACE1, which is a regulatory target of hsa-mir-195. The gene discussed is BACE1; the disease is Alzheimer disease.
