SOAT1 and Parkinson disease: KEGG pathway analysis showed that pathways related to tumor progression and immune response, such as JAK-STAT signaling pathway, B-cell receptor (BCR), T-cell receptor (TCR), and TOLL-like receptor (TLR) signaling pathways, cytokine receptor signaling pathways, and natural killer (NK) cell-mediated cytotoxicity were significantly enriched in the OSMhigh group, whereas, pathways related to Huntington’s and Parkinson’s disease were significantly enriched in the OSMlow group (Figure 8A).
