LYPLAL1 and obesity due to melanocortin 4 receptor deficiency: Currently, there is no study on LYPLAL1-AS1 and cancer, but it has been reported that LYPLAL1-AS1 is closely related to abnormal adipogenesis.[62] The positive correlation between pancreatic ductal adenocarcinoma and the risk of obesity also has been confirmed.[63] Therefore, it can be inferred that LYPLAL1-AS1 can affect the adipogenesis of pancreatic tissue and become a potential molecular target for PAAD.
