Description

Guanghua Nie leads a team uncovering a three-protein complex that drives cartilage breakdown in osteoarthritis, in a 2026 study. The disease wears down the cushioning matrix in joints and has no drug that halts it. A known matrix-eating switch, Runx2, lacked a named partner crew until now.

From arthritic mouse cartilage, the team fished out two proteins bound to Runx2: EYA1 and CIITA. Together the three sit on the start lines of the main matrix-chewing genes and switch them on. Silencing any one member cut those genes sharply. EYA1 also strips a phosphate tag from CIITA at one spot, a step set by another enzyme under inflammatory attack. The authors propose blocking this crew as a route to protect joint cartilage.
