ABSTRACT
Malignant tumors, whose occurrence and development are related to a variety of RNA transporter proteins, seriously affect human health and quality of life. Under normal circumstances, RNA transport proteins help RNA shuttle between nucleus and cytoplasm and their precise localization, effectively coupling the life activities in the nucleus and cytoplasm. During the process of tumorigenesis and progression, the expression and localization of some RNA transporters are abnormal or dysfunctional, which can change the subcellular localization, expression level, transport efficiency of downstream key RNA molecules, and the decay rate of cytoplasmic mRNA, and affect the proliferation, invasion and metastasis of tumors. This paper mainly reviews RNA transport proteins and their expression changes and regulation in tumors.
