Reprogramming NOX4-associated ferro-aging with an iron-chelating senescent-cell-targeted therapy for intervertebral disc degeneration

Intervertebral disc degeneration (IVDD) has been a major contributor to chronic low back pain, yet effective disease-modifying therapies remain limited. Here, we identified a NOX4-associated ferro-aging program linking iron overload, oxidative stress, lipid peroxidation, and cell...

Metabolic-epigenetic nanoregulator attenuates a folate-deficiency-associated senescence phenotype in intervertebral disc degeneration

Intervertebral disc degeneration (IVDD) is increasingly recognized as an aging-associated disorder driven in part by nucleus pulposus cell (NPC) senescence, yet the nutrient-sensitive metabolic defects that sustain this state remain poorly understood. Here, we investigated impair...
