Abstract

Intervertebral disc degeneration (IVDD) is often accompanied by the senescence of nucleus pulposus (NP) cells and narrowed intervertebral disc space. Zinc metalloproteinase STE24 (Zmpste24), a common anti-aging gene, has been studied in several diseases but remains understudied in IVDD. This study aimed to investigate the relationship between IVDD and alterations in Zmpste24 expression. Immunohistochemical staining revealed that reduced Zmpste24 expression in patients with IVDD.

Research summary

Zmpste24 deficiency contributes to intervertebral disc degeneration by affecting the stability of the nuclear membrane in nucleus pulposus cells. This paper explores a potential mechanism linking a known anti-aging gene to a specific age-related degeneration, which aligns with the investigation of root causes of aging.
