DOT1L safeguards cartilage homeostasis and protects against osteoarthritis
Abstract
DOT1L is one of the few genes linked to osteoarthritis by human GWAS. Here the authors show that DOT1L-dependent histone methylation protects homeostasis of articular chondrocytes by SIRT1-dependent inhibition of canonical WNT signalling, and that inhibition of DOT1L can drive osteoarthritic disease in mice.
