Noncoding RNAs regulate alternative splicing in Cancer

Area of Science:

• Molecular Biology
• Cancer Biology
• Genetics

Background:

• Alternative splicing (AS) generates protein diversity but its defects are implicated in cancer.
• Noncoding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, are key regulators in biological processes.
• Dysregulation of AS is a hallmark of cancer, contributing to tumorigenesis and progression.

Purpose of the Study:

• To review mechanisms of ncRNA-mediated regulation of AS in cancer.
• To explore the role of ncRNA-regulated AS in cancer hallmarks like invasion and drug resistance.
• To discuss the clinical potential of ncRNA-AS interactions as cancer biomarkers and therapeutic targets.

Main Methods:

• Literature review of studies on ncRNAs, AS, and cancer.
• Analysis of molecular mechanisms by which ncRNAs influence AS.
• Synthesis of evidence linking ncRNA-AS pathways to cancer progression and clinical outcomes.

Main Results:

• NcRNAs modulate AS by targeting regulatory factors and pre-mRNA.
• Altered AS isoforms driven by ncRNAs contribute to cancer hallmarks.
• Specific ncRNA-AS interactions are associated with cancer invasion, metastasis, and therapy resistance.

Conclusions:

• NcRNAs play a critical role in regulating AS in the context of cancer.
• Targeting ncRNA-AS pathways presents promising avenues for cancer diagnostics and therapeutics.
• Further research is needed to fully elucidate and translate these findings into clinical practice.
