摘　　要：The KAI1/CD82 gene inhibits the metastasis of most tumors and is remarkably correlated with tumor invasion and prognosis.Cell metabolism dysregulation is an important cause of tumor occurrence,development,and metastasis.As one of the important characteristics of tumors,cell metabolism dysregulation is attracting increasing research attention.Phospholipids are an indispensable substance in the metabolism in various tumor cells.Phospholipid metabolites have become important cell signaling molecules.The pathological role of lysophosphatidic acid(LPA)in tumors was identified in the early 1990s.Currently,LPA inhibitors have entered clinical trials but are not yet used in clinical treatment.Autotaxin(ATX)has lysophospholipase D(lysoPLD)activity and can regulate LPA levels in vivo.The LPA receptor family and ATX/lysoPLD are abnormally expressed in various gastrointestinal tumors.According to our recent pre-experimental results,KAI1/CD82 might inhibit the migration and metastasis of cancer cells by regulating the ATX-LPA axis.However,no relevant research has been reported.Clarifying the mechanism of ATX-LPA in the inhibition of cancer metastasis by KAI1/CD82 will provide an important theoretical basis for targeted cancer therapy.In this paper,the molecular compositions of the KAI1/CD82 gene and the ATX-LPA axis,their physiological functions in tumors,and their roles in gastrointestinal cancers and target therapy are reviewed.
