RNA splicing: a new player in the DNA damage response

Area of Science:

• Molecular Biology
• Cancer Research
• Genetics

Background:

• Tumorigenesis involves sequential genetic alterations, but the molecular basis of genomic instability remains incompletely understood.
• Accumulation of DNA damage, often due to mutations in DNA repair and checkpoint genes in hereditary cancers, is a significant driver of oncogenic transformation.
• Identifying cellular pathways involved in DNA damage response is critical for understanding cancer development.

Purpose of the Study:

• To review the emerging role of RNA processing, specifically pre-mRNA splicing, in maintaining genome stability.
• To elucidate the interplay between splicing factors and the DNA damage response (DDR).

Main Methods:

• Literature review focusing on molecular mechanisms linking RNA processing and genome stability.
• Analysis of the role of splicing factors in cellular responses to DNA damage.
• Examination of how DDR activation impacts splicing factor activity.

Main Results:

• Pre-mRNA splicing represents a novel pathway contributing to genome stability.
• Splicing factors are involved in the DNA damage response.
• Activation of the DNA damage response can modulate the activity of splicing factors.

Conclusions:

• The interaction between RNA processing and genome stability is a significant area of cancer research.
• Understanding these mechanisms may reveal new therapeutic targets for cancer treatment.
