Polycystins in disease mechanobiology

Area of Science:

• Mechanobiology
• Molecular Biology
• Cell Signaling

Background:

• Distorted mechanotransduction is a hallmark of disease mechanobiology.
• Polycystins, including polycystin-1 (PC1) and polycystin-2 (PC2), are mechanosensitive proteins crucial for signal transduction.
• Their role is well-studied in polycystic kidney disease but extends to other pathologies.

Purpose of the Study:

• To highlight the contribution of polycystins to disease mechanobiology.
• To explore polycystin-mediated signaling in various pathophysiologies beyond kidney disease.
• To suggest further research into polycystins for force-bearing tissue diseases.

Main Methods:

• Review of emerging data on polycystin function in disease.
• Analysis of polycystin-mediated signaling pathways.
• Comparative study across different disease models.

Main Results:

• Polycystin-mediated signaling is implicated in endothelial dysfunction, atheromatosis, osteoblast differentiation deregulation, cancer, and psoriasis.
• PC1 acts as a mechano-induced membrane receptor, and PC2 functions as a calcium-permeable ion channel.
• These proteins mediate mechanical stimulation, intracellular signaling, and gene transcription.

Conclusions:

• Polycystins play a significant role in the mechanobiology of diverse diseases.
• Further investigation of polycystins is warranted for conditions involving force-bearing tissues.
• Understanding polycystin signaling offers potential therapeutic avenues for multiple diseases.
