Abstract MicroRNAs (miRNAs) are small non-coding RNAs (ncRNAs) that regulate the expression of their target mRNAs post-transcriptionally. Since their discovery, thousands of highly conserved miRNAs have been identified and investigated for their role in human health and diseases. MiR-214 has been increasingly reported to have an association with the regulation of bone metabolism. Reports suggested that miR-214 controls the critical aspects of osteoblasts (bone-forming cells), including their differentiation, proliferation, viability, and migration. Studies have also reported the functional significance of miR-214 in bone diseases and suggested its candidature as a diagnostic and therapeutic target. Further, targeting miR-214 by other ncRNAs, such… More >

Abstract Areca nut is used worldwide as a hallucinogenic addicting drug along the tropical belt. Arecoline, a toxic compound, is the most important alkaloid in areca nuts. The adverse effects of oral uptake and chewing of areca nut are well known. For example, the possibility of cancer caused by chewing areca nuts is widely discussed. Chewing areca nut has other adverse effects on other organs, including abnormal cell differentiation, oral cancer, and several other diseases. The use of areca nut is also associated with low birthweight. Skeletal musculature is the largest organ in the body and is attached to the bones.… More >

Abstract To evaluate the characteristics and synthesis activity of osteoblasts extracted from the calvaria of offspring of rats exposed to maternal hyperthyroidism. Twelve adult Wistar rats were divided into two groups, one control and one treated with daily administration of L-thyroxine by an orogastric tube (50 µg/animal/day) during pregnancy. Three days after delivery and confirmation of the mothers’ hyperthyroidism, the offspring were euthanized for the extraction of osteoblasts from the calvaria. At 7, 14, and 21 days, proliferation activity was assessed using MTT assay, while alkaline phosphatase (ALP) activity was assessed by the BCIP/NBT method. At 21 days, the total area… More >

Abstract CDK5 belongs to the cyclin-dependent kinase family. CDK5 is multifunctional and plays an important role in neural differentiation. However, the role of CDK5 in osteoblastic differentiation remains unclear. The present study investigated functions and molecular mechanism of CDK5 in osteoblastic differentiation. It was found that, CDK5 inhibition promoted the expression of Runx2, ALP, OCN and OPN of MSCs and the mineralization of MC-3T3E1 cells and MSCs. CDK5 inhibition enhanced the development of F-actin, nuclear localization of β-catenin and YAP, as well as the expression of RMRP RNA. When F-actin was suppressed by Blebbistatin, the nuclear localization of YAP and β-catenin,… More >

Abstract Orthodontic tooth movement is triggered by orthodontic force loading on the periodontal ligament and is achieved by alveolar bone remodeling, which is regulated by intimate crosstalk between osteoclastogenesis and osteoblast differentiation. Whether the communication between osteoclasts and osteoblasts is influenced by orthodontic compression stress requires further clarification. In this study, osteoclasts were differentiated for 10 days. On day 4 of differentiation, the number of pre-osteoclasts peaked, as determined by the increased expression of RANK and the number of multinucleated cells. After 24 h of compression stress loading, on day 4, the number of osteoclasts increased, and the optimal magnitude of… More >

Abstract Periodontitis is a type of chronic inflammation in the gingival tissue caused by infectious bacteria colonizing the surface of the teeth, leading to the destruction of tooth-supporting tissues and loss of alveolar bone. Suberoylanilide hydroxamic acid (SAHA), a class of histone deacetylase (HDAC) inhibitor, has the potential to stimulate osteoblast differentiation by acetylating histone proteins, and thus suppressing the expression of adipogenic and chondrogenic genes. However, the effect of SAHA on the differentiation of human periodontal ligament stem cells (hPDLSCs) is yet to be elucidated. Herein, we investigated the effects of SAHA on in vitro proliferation and differentiation of hPDLSCs… More >

Abstract Autophagy is an essential cellular homeostatic mechanism by which intracellular components are delivered into the lysosomes for degradation and recycling. Autophagy has been related with a diversity of pathological or physiological dentary processes such as bone remodeling, skeletal aging, osteoclastogenesis, osteoblastogenesis and different types of oral cancer. Platelet-rich plasma (PRP), isolated from autologous blood, is a plasma preparation containing a higher concentration of platelets which contains numerous different growth factors and cytokines that activate several cellular signaling cascades. The purpose of this study is to investigate the effect of PRP on autophagy stimulation in both osteoblast precursor 3T3-L1 and non-related… More >

Abstract Random positioning machine (RPM) and diamagnetic levitation are two essential ground-based methods used to stimulate the effect of microgravity in space life science research. However, the force fields generated by these two methods are fundamentally different, as RPM generates a dynamic force field acting on the surface in contact with supporting substrate, whereas diamagnetic levitation generates a static force field acting on the whole body volume of the object (e.g. cell). Surprisingly, it is hardly studied whether these two fundamentally different force fields would cause different responses in mammalian cells. Thus we exposed cultured MC3T3-E1 osteoblasts to either dynamically stimulated… More >
