研究问题

Osteoporosis (OP) constitutes a major global public health burden whose progression is closely linked to mitochondrial dysfunction and disrupted mitophagy homeostasis.

方法

This study was designed to characterize the critical function of voltage-dependent anion-selective channel protein 1 (VDAC1), an outer mitochondrial membrane channel protein, in OP and clarify the underlying mechanisms of VDAC1 modulating…

核心结论

Bioinformatic analysis of postmenopausal osteoporosis dataset GSE230665 identified VDAC1 as a core node linking mitophagy and osteoporosis.;In vivo, AAV9-VDAC1 overexpression vector (AAV9-OE-VDAC1) alleviated osteoporotic phenotypes in ovariectomized (OVX) mice.;In vitro, VDAC1 overexpression restored mitophagy and facilitated osteogenic differentiation of hydrogen peroxide (H2O2) -damaged bone marrow mesenchymal stem cells (BMSCs).

对本项目的价值

临床前机制证据,需评估物种外推与剂量可行性:线粒体是衰老干预的共同下游效应器,可用于跨器官效应的统一读数。 | 价值分 1.4/5(★☆☆☆☆)

B 级证据分级:B 级(同行评议临床前研究,主要为动物模型)

本文核心结论来自动物模型或体外细胞学,属临床前证据,不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义,与人类临床结局之间仍有距离。
