Attenuation of the degenerative effects of endothelin-1 on cartilaginous end plate cells by the endothelin receptor antagonist BQ-123 via the Wnt/β-catenin signaling pathway

Endothelin-1 can reduce levels of collagen II, aggrecan, and SOX9 in CECs through activation of the Wnt/β-catenin signaling pathway, whereas BQ-123 attenuates these negative effects, highlighting a new molecular mechanism with potential for exploitation for treatment of CEP degeneration.
