MAPK Pathways in Ocular Pathophysiology: Potential Therapeutic Drugs and Challenges

Area of Science:

• Cell Biology
• Molecular Biology
• Ophthalmology

Background:

• Mitogen-activated protein kinase (MAPK) pathways are fundamental cellular signal transduction cascades involved in diverse biological processes.
• Dysregulation of MAPK signaling is frequently observed in various disease states, including ocular pathologies.
• MAPKs, upon activation by phosphorylation, regulate transcription factors, influencing gene expression and cellular responses.

Purpose of the Study:

• To provide a comprehensive review of the roles of MAPK signaling pathways in ocular pathophysiology.
• To explore the therapeutic potential of targeting MAPK pathways for treating eye diseases.
• To summarize current knowledge on MAPK-targeting compounds for ocular conditions and discuss challenges.

Main Methods:

• Literature review of scientific publications on MAPK pathways and ocular diseases.
• Synthesis of information on MAPK involvement in common and rare eye conditions.
• Analysis of existing and potential therapeutic interventions targeting MAPK signaling in ophthalmology.

Main Results:

• MAPK pathways play significant roles in the pathophysiology of macular degeneration, cataract, glaucoma, and keratopathy.
• Specific MAPK-targeting compounds have been identified for potential therapeutic use in these ocular diseases.
• Challenges include the eye toxicity associated with some MAPK inhibitors, necessitating careful consideration for therapeutic development.

Conclusions:

• MAPK signaling pathways are critical targets for therapeutic intervention in a range of ocular diseases.
• Further research is needed to optimize MAPK-targeted therapies, addressing efficacy and mitigating potential toxicity.
• Understanding MAPK roles in cell differentiation, proliferation, and migration is key to treating rare ocular disorders.
