Perturbations of RNA helicases in cancer

Area of Science:

• Molecular Biology
• Biochemistry
• Oncology

Background:

• Helicases are enzymes essential for gene expression, including DNA replication, RNA transcription, translation, and decay.
• These enzymes use nucleotide triphosphate hydrolysis to modify nucleic acids and protein complexes, impacting RNA function.
• Dysregulation of RNA helicases, through mutations or altered expression, is linked to cancer initiation and progression.

Purpose of the Study:

• To review RNA helicases implicated in cancer biology.
• To highlight enzymes with significant evidence linking them to oncogenic processes.
• To provide an overview of RNA helicase roles in tumor initiation, progression, maintenance, and chemosensitivity.

Main Methods:

• Literature review of scientific publications.
• Identification of RNA helicases with documented roles in cancer.
• Synthesis of evidence linking RNA helicase function to cancer biology.

Main Results:

• Several RNA helicases show altered expression or mutations in various cancers.
• These RNA helicases are involved in critical pathways for tumor growth and survival.
• Evidence links specific RNA helicases to tumor maintenance and response to chemotherapy.

Conclusions:

• RNA helicases are significant players in cancer development and progression.
• Targeting RNA helicases presents a potential therapeutic strategy for cancer treatment.
• Further research into RNA helicase functions in oncology is warranted.
