Depletion of the autophagy adaptor OPTN leads to increased osteoclast formation, fusion and survival as well as increased NF-κB activation in vitro

Obaid Rami , Wani Sachin , Ralston Stuart , Albagha Omar

OPTN encodes a cytoplasmic protein optineurin which has been shown to play a role in autophagy. Recent GWAS studies have shown that variants within OPTN are associated with the risk of Paget’s disease of bone, a disease characterized by focal areas of increased bone turnover due to increased osteoclast activity, suggesting a possible role of OPTN in the regulation of bone metabolism.The aim of this study was to investigate the role of optineurin in ...

The D477N mutation in OPTN leads to increased bone turnover and enhanced osteoclast formation in OptnD477N/D477N mice

Wani Sachin , Obaid Rami , Jones Ruth , Cohen Philip , Ralston Stuart , Albagha Omar

Recent GWAS have identified variants in the OPTN gene that predispose to Paget’s disease of Bone (PDB), a disease characterised by focal areas of increased bone turnover and enhanced osteoclast activity, suggesting a role for this gene in bone metabolism. The aim of this study was to investigate the role of OPTN in bone metabolism using a mouse model (OptnD477N/D477N) which harbours a D477N point mutation in the polyubiquitin binding ...
