Ciliary Neurotrophic Factor (CNTF) Inhibits In Vitro Cementoblast Mineralization and Induces Autophagy, in Part by STAT3/ERK Commitment.

ABSTRACT: In animal models, the administration of ciliary neurotrophic factor (CNTF) was demonstrated to reduce bone mass and to participate in bone remodeling. Cementoblasts, a cell type embedded in the cementum, are the main cells to produce and mineralize the extracellular matrix. The effect of CNTF on cementoblasts has not yet been addressed. Thus, the goal of this in vitro study was to investigate possible influences of exogenous CNTF on cementogenesis, as well as autophagy regulation and subsequent mechanisms in cementoblasts. Cementoblasts (OCCM-30) were stimulated with exogenous CNTF. Alizarin Red staining was performed to analyze the functional differentiation (mineralization) of OCCM-30 cells. The release of OPG was quantified by ELISA. The expression of cementogenesis markers (RUNX-2</
