To correlate lipids with metabolic function, we performed PatternHunter [42] using the differentially expressed lipids based on their component identification number (CID) and found that glycerolipid metabolism, metabolic pathways, thermogenesis, regulation of lipolysis in adipocytes, insulin resistance, fat digestion and absorption, vitamin digestion and absorption, cholesterol metabolism, and lipid and atherosclerosis were differentially affected following CPAP treatment. The gene discussed is INS; the disease is atherosclerosis.
