简要总结
Obesity is now becoming a worldwide serious problem. Obesity is associated with a spectrum of severe diseases, including diabetes, cardiovascular diseases, and cancers. Lipocalin 2 (LCN2), also known as neutrophil gelatinase associated lipocalin (NGAL), is a member of the lipocalin family. Due to its upregulated expression in infection, LCN2 is originally considered to be a key regulator of immune response. Subsequent investigations revealed that LCN2 is expressed in many tissues and is related to a variety of diseases, including obesity. LCN2 was reported to be increased in obesity individuals. Thus, the investigators decide to investigate the relationship between LCN2 and obesity.
