Abstract: Minichromosome maintenance(MCM)proteins are important substances in the DNA replication process of eukaryotic cells,and are involved in the initiation and elongation of DNA replication.When certain factors cause the abnormal expression of MCM protein,cells in the quiescent phase start a new cell cycle,abnormal DNA replication occurs,and cells begin to proliferate indefinitely,resulting in tumorigenesis.Therefore,MCM protein is considered as a new tumor marker.Digestive system tumors are closely related to MCM protein.Exploring the MCM protein can bring new methods for the diagnosis and treatment of digestive system tumors.

Key words: Minichromosome maintenance protein, Digestive system tumor, Tumor marker
