Abstract:
Chimeric RNA is a fusion transcript composed of exons from two or more different genes and generated by chromosome rearrangement or RNA splicing. Chimeric RNAs have the potential to encode novel proteins or function as non-coding RNAs. Chimeric RNAs were ubiquitously expressed across different cancers and normal tissues. To date, mechanistic and functional studies of chimeric RNAs still remain unclear. Precise definition and terminology in the research field of chimeric RNA will be discussed in this review. The formation, classification and clinical significance of chimeric RNAs in cancer progression will be summarized. Previous studies showed that products of chimeric RNAs may play important roles in regulating cell proliferation, motility, invasion and apoptosis through encoded fusion proteins or long non-coding chimeric RNAs. In cancer, chimeric RNA and its encoded specific protein or non-coding RNA can regulate tumorigenesis by changing cell phenotypes or directly affecting gene expression or regulatory pathways, which have the potential to be important diagnostic biomarkers and therapeutic targets. In recent years, more and more cancer-specific chimeric RNAs have been discovered from multiple types of cancers and used as therapeutic targets due to their vital roles in disease prognosis. Therefore, this review will focus on the functions and applications of chimeric RNAs in different tumors, which can shed a light on cancer diagnosis and therapeutics from the new perspective.
