Oncometabolites as Regulators of DNA Damage Response and Repair

Area of Science:

• Oncology
• Metabolism
• Molecular Biology

Background:

• DNA damage response and repair (DDR) pathways are crucial in cancer development.
• Dysregulation of DDR is a hallmark of cancer and a target for therapy.
• Oncometabolites, overproduced metabolic intermediates, are increasingly recognized as modulators of DDR.

Purpose of the Study:

• To review the biology of oncometabolites.
• To elucidate the mechanisms by which oncometabolites impact DDR.
• To discuss therapeutic strategies targeting oncometabolite-induced DDR defects.

Main Methods:

• Literature review of oncometabolite biology and DDR.
• Analysis of mechanisms linking oncometabolites to DDR pathways.
• Survey of emerging therapeutic strategies and clinical trials.

Main Results:

• Oncometabolites can disrupt multiple DNA repair pathways.
• Oncometabolite-induced DDR defects present opportunities for synthetic lethality.
• Targeting these defects may lead to tumor-selective chemo- and radio-sensitization.

Conclusions:

• Oncometabolites represent a novel class of DDR modulators in cancer.
• Targeting oncometabolite-induced DDR defects is a promising therapeutic avenue.
• Ongoing clinical trials are evaluating these strategies in cancer patients.
