摘要
Glucagon-like peptide-1 receptor(GLP-1R)agonist,a subgroup of incretin-based anti-diabetic therapies,is an emerging medication with benefits in reducing blood glucose and weight and increasing cardiovascular protection.Contrarily,concerns have been raised about GLP-1R agonists increasing the risk of particular cancers.Recently,several epidemiological studies reported contradictory findings of incretin-based therapy on the risk modification for cholangiocarcinoma(CCA).The first cohort study demonstrated that incretin-based therapy was associated with an increased risk of CCA.Later studies,however,showed a null effect of incretinbased therapy on CCA risk for dipeptidyl peptidase-4 inhibitor nor GLP-1R agonist.Mechanistically,glucagon-like peptide 1 receptor is multifunctional,including promoting cell growth.High GLP-1R expressions were associated with progressive phenotypes of CCA cells in vitro.Unexpectedly,the GLP-1R agonist showed anti-tumor effects on CCA cells in vitro and in vivo with unclear mechanisms.Our recent report also showed that GLP-1R agonists suppressed the expression of GLP-1R in CCA cells in vitro and in vivo,leading to the inhibition of CCA tumor growth.This editorial reviews recent evidence,discusses the potential effects of GLP-1R agonists in CCA patients,and proposes underlying mechanisms that would benefit from further basic and clinical investigation.
