OXT and Huntington disease: In the KEGG pathway analysis, the 211 DEGs were mainly enriched in ECM-receptor interaction and neuroactive ligand-receptor interaction, and the 1519 DEGs were mainly enriched in dopaminergic synapse, oxytocin signaling pathway, epithelial cell signaling in helicobacter pylori infection, prion diseases, NOD-like receptor signaling pathway, and Huntington's disease (Figure 5).
