PPARA and viral infectious disease: Using the UniProt Gallus gallus (chicken) database as the reference protein library, the pathways of the selected interacting proteins were analysed, and multiple innate immune response pathways, including the PI3K-Akt signalling pathway, the RNA transport pathway, the mTOR signalling pathway, the proteoglycan synthesis pathway, the axon-directed regeneration pathway, the cell cycle pathway, the DNA replication pathway, the PPAR signalling pathway, the endocytosis pathway, the viral infection pathway, and the animal mitotic phagocytosis pathway were identified (Table 3).
