Deferoxamine Alleviates Osteoarthritis by Inhibiting Chondrocyte Ferroptosis and Activating the Nrf2 Pathway

Frontiers in Pharmacology, 2022
Objective: Osteoarthritis (OA) is a common disease with a complex pathology including mechanical load, inflammation, and metabolic factors. Chondrocyte ferroptosis contributes to OA progression.

NAT10-mediated ac4C modification of KDM1B drives osteoarthritis progression through epigenetic suppression of SOX9 [PDF]

Cellular and Molecular Life Sciences
Histone methylation acts as a crucial regulator of diverse pathophysiological processes in humans. However, the involvement of histone methylation modification enzymes in osteoarthritis (OA) remains poorly characterized.

Functional Duality of Chondrocyte Hypertrophy and Biomedical Application Trends in Osteoarthritis

Pharmaceutics, 2021
Chondrocyte hypertrophy is one of the key indicators in the progression of osteoarthritis (OA). However, compared with other OA indications, such as cartilage collapse, sclerosis, inflammation, and protease activation, the mechanisms by which chondrocyte
