# Progress on the mechanism of Polycystin-1 in bone remodeling

## TL;DR

This review explores how the protein Polycystin-1 influences bone remodeling and its potential for treating bone-related diseases.

## Contribution

The paper provides a detailed analysis of PC-1's role in bone homeostasis and its interaction with tafazzin.

## Key findings

- PC-1 deficiency disrupts bone remodeling and affects bone mass and skeletal development.
- PC-1 interacts with tafazzin to regulate bone remodeling in response to mechanical forces.
- PC-1 has potential therapeutic applications for osteoporosis and cranial suture closure.

## Abstract

Polycystin-1 (PC-1), a transmembrane protein expressed on cell membranes, plays a vital role in cell signaling and intercellular adhesion. Existing studies have shown that PC-1 plays a pivotal role in bone remodeling and that PC-1 deficiency results in disrupted bone remodeling, which markedly affects bone mass and skeletal development. This review describes the molecular structure and biological function of PC-1 and analyzes the mechanism by which it maintains bone homeostasis and regulates osteoblast and osteoclast activity. Particular emphasis is placed on the role of PC-1 in mechanical force-triggered bone remodeling and its interaction with the transcriptional co-activator tafazzin. Moreover, this review outlines the potential applications of PC-1 in treating skeletal diseases, such as osteoporosis, fractures, and premature closure of cranial sutures, thereby providing a theoretical basis for future research.
