ZSZhi‐Han ShenShanghai Jiao Tong University XLX G LiQingdao University JLJian LuShanghai Eighth People Hospital

Key Points

The study investigates the role of IGF2BP2 deficiency in cartilage degeneration and cellular aging.
Assessed the role of IGF2BP2 in chondrocytes and its effect on HIF-1α regulation.
Examined the PINK1/Parkin pathway and its association with mitochondrial dysfunction.
Investigated the impact of IGF2BP2 on cellular senescence and articular cartilage integrity.
Downregulation of IGF2BP2 resulted in decreased HIF-1α levels, contributing to mitochondrial dysfunction.
The activation of the PINK1/Parkin pathway was implicated in the senescence of chondrocytes.
Cartilage degeneration was exacerbated due to cellular aging linked to IGF2BP2 deficiency.

Abstract

A reader IGF2BP2 in the pathogenesis of cartilage degeneration through downregulation of HIF-1α and extends the potential role of the PINK1/Parkin pathway, downregulation of which leads to the onset of mitochondrial dysfunction and senescence in the progression of articular cartilage loss.
