Furthermore, the significantly obtained biological process and the pathways of the miRNA-based network were reflective of the known processes and pathways in PD, such as the regulation of the G1/S transition of the mitotic cell cycle, the regulation of autophagy, cell differentiation, p53 pathway, the oxidative stress response, the interferon-gamma signaling pathway, and the JAK/STAT signaling pathway. The gene discussed is SOAT1; the disease is Parkinson disease.
