LPL hydrolyzes triglyceride (TG) into fatty acid and glycerol (Bechmann et al. 2012) and hepatic lipase deficiency exhibited glucose intolerance and hepatic steatosis (Andres-Blasco et al. 2015), whereas increasing LPL rescued glucose and insulin tolerance in high fat diet-induced obesity (Walton et al. 2015). This evidence concerns the gene INS and hepatitis A virus infection.
