Do human RNA helicases have a role in cancer?

Human RNA helicases (HRH) represent a large family of enzymes that play important roles in RNA processing. The biochemical characteristics and biological functions of the majority of HRH are still to be determined. However, there are examples of dysregulation of HRH expression in various types of cancer. In addition, some HRH have been shown to be involved in the regulation of, or the molecular interaction with, molecules implicated in cancer. Other helicases take part in fusion transcripts resulting from cancer-associated chromosomal translocation. These findings raise the question of whether HRH can contribute to cancer development/progression. In this review, I summarize the cancer-related features of HRH.
