Gene fusions and their encoded products (fusion RNAs and proteins) are viewed as
one of the hallmarks of cancer. Traditionally, they were thought to be generated
solely by chromosomal rearrangements. However, recent discoveries of
trans-splicing and cis-splicing events between neighboring genes, suggest that
there are other mechanisms to generate chimeric fusion RNAs without corresponding
changes in DNA. In addition, chimeric RNAs have been detected in normal
physiology, complicating the use of fusions in cancer detection and therapy. On
the other hand, "intergenically spliced" fusion RNAs represent a new repertoire
of biomarkers and therapeutic targets. Here, we review current knowledge on
chimeric RNAs and implications for cancer detection and treatment, and discuss
outstanding questions for the advancement of the field.
