Cisplatin-Induced Ototoxicity: Updates on Molecular Targets

Area of Science:

• Oncology
• Ototoxicology
• Molecular Biology

Background:

• Cisplatin is a vital chemotherapy drug for various cancers.
• Cisplatin use leads to ototoxicity, manifesting as hearing loss.
• While oxidative stress is implicated, inflammation may initiate inner ear cell death pathways.

Purpose of the Study:

• To review the molecular targets of cisplatin.
• To elucidate intracellular pathways driving cisplatin-induced ototoxicity.
• To identify signal transduction processes for preventing hearing loss.

Main Methods:

• Literature review of molecular targets.
• Analysis of intracellular pathways (ER stress, autophagy, necroptosis, apoptosis).
• Focus on signal transduction mechanisms.

Main Results:

• Cisplatin targets include DNA and proteins, initiating cellular damage.
• Inflammation acts as a potential trigger for inner ear cell death.
• Multiple cell death pathways (ER stress, autophagy, necroptosis, apoptosis) are involved.

Conclusions:

• Understanding cisplatin's molecular interactions is crucial.
• Inflammation-mediated pathways offer targets for ototoxicity prevention.
• Developing strategies to mitigate cisplatin-induced hearing loss is essential due to its social impact.
