Punica granatum (PG) contained anthocyanin, the chemical compound that played significant role in increasing bone cell proliferabbitsion and osteoblasts differentiation in bone remodelling. This research was aimed at measuring the effect of Punicagranatum on maxilla bone remodelling relating to the profile of both osteoblast and osteoclast. Punicagranatum was extracted by using butanol while the analysis of bone remodelling was conducted by observing the profile of osteoblast and osteoclast cells using histopathologic method. Butanol hydrogel of Punicagranatum was abled to enhance bone reabsorption which was proven by the increase of osteoclast and new bone formation since the osteoblast was presented. Moreover, bone remodelling activity was characterised by increased collagen fibres and osteocyte cell, in addition, bone shape compactness was getting better. Statistical analysis revealed that the histoscore profile of osteoblast was influenced by butanol fraction dosage with significance level (p<0.05) which was at medium criteria according to Pearson correlation (r=0,6). While the effect of dosage on osteoclast was at significance level (p<0.05) but was poorly correlated with (r=0.01) and osteoblast frequency was dominant at the concentrabbitsion of 125 mg/ml and 250 mg/ml. On the other hand, at the concentrabbitsion of 175 mg/ml osteoclast presentation was found to be more dominant. The fraction of butanol PG was abled to induce osteoblast increment and osteoclast at the concentrabbitsion of (mg/ml) 125, 175, and 250 and accelerabbitse the remodelling of alveolar maxilla.

Transforming growth factor β1 (TGFβ1) is a major mediator in the modulation of osteoblast differentiation. However, the underlying molecular mechanism is still not fully understood. Here, we show that TGFβ1 has a dual stage-dependent role in osteoblast differentiation; TGFβ1 induced matrix maturation but inhibited matrix mineralization. We discovered the underlying mechanism of the TGFβ1 inhibitory role in mineralization using human osteoprogenitors. In particular, the matrix mineralization-related genes of osteoblasts such as osteocalcin (OCN), Dickkopf 1 (DKK1), and CCAAT/enhancer-binding protein beta (C/EBPβ) were dramatically suppressed by TGFβ1 treatment. The suppressive effects of TGFβ1 were reversed with anti-TGFβ1 treatment. Mechanically, TGFβ1 decreased protein levels of C/EBPβ without changing mRNA levels and reduced both mRNA and protein levels of DKK1. The degradation of the C/EBPβ protein by TGFβ1 was dependent on the ubiquitin–proteasome pathway. TGFβ1 degraded the C/EBPβ protein by inducing the expression of the E3 ubiquitin ligase Smad ubiquitin regulatory factor 1 (SMURF1) at the transcript level, thereby reducing the C/EBPβ-DKK1 regulatory mechanism. Collectively, our findings suggest that TGFβ1 suppressed the matrix mineralization of osteoblast differentiation by regulating the SMURF1-C/EBPβ-DKK1 axis.
