The competing endogenous RNA (ceRNA) hypothesis is a new pattern of gene posttranscriptional regulation. Encoding mRNA, long noncoding RNA (lncRNA), pseudogene transcript, circular RNA (circRNA), etc. can regulate gene expression by binding microRNA (miRNA). According to the research, ceRNA regulatory network participates in the maintenance of normal physiological state, occurrence and development of diseases. This paper reviewed ceRNA with the following respects: the proposal of ceRNA hypothesis, members of ceRNA regulatory network, research status, limitations and future development directions of this hypothesis. It will contribute to clarify the pathogenesis of much diseases including tumor and provide a new strategy for the diagnosis and treatment of disease.
