Bone morphogenetic proteins (BMPs)는 다양한 세포기능을 조절하는 중요한 사이토카인 중 하나이다. 최근 BMP와 일주기 유전자들이 연관되어 있다는 연구결과들이 보고되고 있지만 조골세포에서 일주기 유전자인 Per1의 역할은 아직 명확하지 않다. 본 연구에서는 조골세포 분화에서 Per1의 역할을 조사하였다. MC3T3-E1 세포에서 BMP2 처리에 의해 Per1 mRNA 발현과 luciferase 활성이 증가하는 것을 확인하였다. 또한 Per1 과발현 실험을 통해서 Per1 유전자가 Runx2, ALP, OC의 발현을 증가시켰으며 ascorbic acid와 β-glycerophosphate에 의한 ALP염색과 석회화가 Per1 과발현에 의해 더욱 증가하는 것을 확인하였다. 이상의 결과는 일주기 리듬을 조절하는 Per1 유전자가 조골세포의 분화를 촉진하는 인자로 작용함을 시사한다.

Bone morphogenetic proteins (BMPs) are multifunctional cytokines that play important roles in a variety of cellular functions. Among BMP family members, BMP2 efficiently promotes osteoblast differentiation through Smad-mediated runt-related transcription factor 2 (Runx2) expression. Several recent studies suggest that BMPs are associated with clock genes, in particular Bmal1. Bmal1 protein heterodimerizes with Clock protein and then induces period 1 (Per1) expression. However, the role of Per1 on osteoblast differentiation remains unclear. In this study, we investigated whether Per1 is involved in osteoblast differentiation. MC3T3-E1 cells were treated with BMP2 for induction of osteoblastic differentiation. Osteogenic maker gene and Per1 mRNA expression were measured using real-time PCR. Interestingly, BMP2 treatment induced Per1 mRNA expression in MC3T3-E1 cells. To further investigate the function of Per1 on osteoblast differentiation, MC3T3-E1 cells were transiently transfected with pCMV-Per1. Per1 overexpression increased Runx2 mRNA and protein levels. Also, mRNA expression and promoter activity of osteocalcin were upregulated by Per1 overexpression. To investigate the effect of interaction between Per1 and osteogenic condition, MC3T3-E1 cells were cultured in osteogenic medium containing ascorbic acid and β-glycerophosphate. Osteogenic medium-induced ALP staining level and mineralization were synergistically increased by overexpression of Per1. Taken together, these results demonstrate that Per1 is a positive regulator of osteoblast differentiation.
