In PPARα KO stroke brains, we observed the enrichment of Gene Ontology (GO) Biological Processes and Molecular Functions for the following gene sets: the positive regulation of leukocyte proliferation (−log10 (p-value) = 4.501, Enrichment = 7.871), positive regulation of apoptotic process (−log10 (p-value) = 3.345, Enrichment = 3.349), acute-phase response (−log10 (p-value) = 3.137, Enrichment = 16.962), and cellular component disassembly (−log10 (p-value) = 2.235, Enrichment = 3.699) (Figure 2C). The gene discussed is PPARA; the disease is stroke disorder.
