Methyl-CpG-binding domain 2 mitigates osteoarthritis through Steap3 promoter methylation and chondrocyte ferroptosis regulation
This study demonstrates that Methyl-CpG-binding domain 2 (MBD2) plays a crucial role in mitigating osteoarthritis (OA) by regulating Steap3 promoter methylation and chondrocyte ferroptosis. Increased MBD2 expression was observed in OA cartilage, but its nuclear import was reduced. Cartilage-specific Mbd2 knockout exacerbated OA progression and accelerated OA progression. MBD2 binds to the Steap3 promoter, modulating its methylation and influencing ferroptosis by regulating ferric to ferrous iron reduction. Inhibiting ferroptosis or knocking down Steap3 alleviated OA induced by MBD2 deletion, while Mbd2 overexpression partially mitigated DMM-induced OA. This highlights MBD2 as a potential therapeutic target for OA.

MBD2 Upregulation in OA Cartilage
MBD2 expression is significantly increased in OA cartilage tissues from both humans and mice with destabilization of the medial meniscus (DMM)-induced OA. However, its nuclear import is reduced in OA, suggesting a complex regulatory mechanism. Specific knockout of Mbd2 in cartilage exacerbates cartilage degradation and accelerates OA progression, highlighting MBD2's protective role in chondrocyte homeostasis.

RNA sequencing revealed that MBD2 deletion induces ferroptosis in chondrocytes. Ferroptosis is a regulated cell death characterized by iron accumulation and lipid peroxidation. MBD2's role in mitigating ferroptosis suggests a novel pathway in OA pathogenesis.

Impacts ferroptosis in chondrocytes
MBD2 directly binds to the Steap3 promoter region and regulates its methylation status. STEAP3, a metalloreductase, catalyzes the reduction of ferric iron (Fe³+) to ferrous iron (Fe²+) within endosomes, which is a key step in initiating ferroptosis. Reduced methylation of the Steap3 promoter due to MBD2 deletion leads to increased STEAP3 expression and subsequent ferroptosis.
Therapeutic Potential: Steap3 Knockdown
Adeno-associated virus-mediated Steap3 knockdown alleviated OA induced by MBD2 deletion. This intervention reduced cartilage damage, synovial inflammation, and osteophyte formation, demonstrating that targeting STEAP3 can rescue the detrimental effects of MBD2 deficiency.
Impact: Reduced OA severity and inflammation.
