Abstract

This study investigates the effects of paricalcitol, a vitamin D analog, on vascular smooth muscle cells (VSMCs) in the context of phosphate-induced activation of the Wnt/β-catenin signaling pathway, which is a critical factor in vascular calcification. The researchers found that paricalcitol can inhibit phosphate-induced activation of this pathway, thus potentially preventing vascular calcification.

摘要

本研究旨在探讨维生素D类似物帕立骨化醇（paricalcitol）对血管平滑肌细胞（VSMCs）中磷酸盐诱导的Wnt/β-连环蛋白信号通路激活的抑制作用。研究发现，磷酸盐会诱导Wnt/β-连环蛋白信号通路的激活，导致VSMCs的钙化。帕立骨化醇能够有效地阻止这种激活，从而可能预防血管钙化。

Key Findings

1. **Phosphate-Induced Activation**: Phosphate was shown to induce the Wnt/β-catenin pathway in VSMCs, leading to vascular calcification.

2. **Role of Paricalcitol**: Paricalcitol effectively prevented the activation of the Wnt/β-catenin pathway in these cells.

3. **Mechanism of Action**: The study suggests that paricalcitol's inhibition of this pathway is a potential mechanism for its protective effects against vascular calcification.

主要发现

1. **磷酸盐诱导的激活**: 磷酸盐在血管平滑肌细胞中诱导了Wnt/β-连环蛋白信号通路的激活，这与血管钙化相关。

2. **帕立骨化醇的作用**: 帕立骨化醇有效地抑制了磷酸盐诱导的Wnt/β-连环蛋白信号通路的激活。

3. **作用机制**: 帕立骨化醇通过抑制Wnt/β-连环蛋白信号通路，展示了其预防血管钙化的潜力。
