HO1 activates autophagy to protect intervertebral disc degeneration


ABSTRACT: Intervertebral disc degeneration (IDD) is majorly resulted from disordered extracellular matrix (ECM) metabolism, including decreased anabolism and increased catabolism activities in the nucleus pulposus (NP) cells of discs. Pro-inflammatory cytokines such as interleukin-1β (IL-1β) are considered to be potent mediators of ECM loss. We reported previously that hemeoxygenase-1 (HO-1) inducer cobalt protoporphyrin IX (CoPP) could attenuate the ECM breakdown which induced by IL-1β, however, the underlying mechanism remains elusive. Here we found that autophagy family genes were involved in the HO-1 mediated anti-inflammatory processes in human NP cells by using high throughput RNA-Seq technique. These findings suggest that autophagy might play a role in inflammation related ECM metabolism disorder, thus offering a direction of our in-depth study and providing a framework for the searching of potential therapeutic targets in the treatment of IDD
