Popis: | To the Editor, I read with great interest an article that was written by Lange et al. This article was published in June 2013 and is about the effect of Denosumab on aneurysmal bone cyst [1].The authors showed well that Denosumab can be a new treatment option for aneurysmal bone cyst. I would like to complete the discussion of Lange and colleagues by introducing a major complementary route by which Denosumab could heal bone cyst. Reduced numbers of osteoblasts could decrease bone turnover and imbalanced remodeling leading to increased bone resorption. It is generally accepted that stem cell differentiation, which is essentially regulated by WNT/β-catenin signaling, plays an important determinant of osteoblastogenesis [2]. Recruitment of pre-osteoclasts by expression of the ligand for receptor activator of the nuclear factor-kappa b (RANKL) is essential for osteoclastogenesis [3]. Denosumab, a monoclonal RANKL antibody, not only effectively inhibits RANKL, which can lead to significant reduction of osteoclasts, but also increases osteoblastogenesis via inhibition of DKK1, which is antagonist of WNT/β-catenin pathway [4]. Therefore, these important mechanisms should be borne in mind as the major mechanisms for Denosumab for treatment of bone cyst. |
