DNA damage response in cisplatin-induced nephrotoxicity

Area of Science:

• Oncology
• Nephrology
• Molecular Biology

Background:

• Cisplatin is a vital chemotherapy agent but causes severe side effects, including acute kidney injury (AKI).
• Cisplatin-induced AKI is linked to damage in renal tubular cells.
• The DNA damage response (DDR) is increasingly recognized as a key factor in cisplatin nephrotoxicity.

Purpose of the Study:

• To explore the role of DNA damage and DDR in cisplatin-induced AKI.
• To identify potential therapeutic targets for preventing cisplatin nephrotoxicity.

Main Methods:

• Review of recent studies on cisplatin nephrotoxicity and DDR.
• Analysis of the mechanisms linking DNA damage to renal cell injury and death.

Main Results:

• Cisplatin accumulation in renal tubular cells triggers DNA damage.
• Activation of DDR pathways can lead to cell cycle arrest, DNA repair, or cell death.
• DDR plays a critical role in the pathogenesis of cisplatin-induced AKI.

Conclusions:

• DNA damage and DDR are central to cisplatin nephrotoxicity.
• Targeting DDR pathways presents a promising strategy for renoprotection in cancer patients.
