Abstract
Osteoporosis, a chronic complication of diabetes mellitus, is characterized by a reduction in bone mass, destruction of bone microarchitecture, decreased bone strength, and increased bone fragility. Because of its insidious onset, osteoporosis renders patients highly susceptible to pathological fractures, leading to increased disability and mortality rates. However, the specific pathogenesis of osteoporosis induced by chronic hyperglycemia has not yet been fully elucidated. But it is currently known that the disruption of Wnt signaling triggered by chronic hyperglycemia is involved in the pathogenesis of diabetic osteoporosis. There are two main types of Wnt signaling pathways, the canonical Wnt signaling pathway (β-catenin-dependent) and the non-canonical Wnt signaling pathway (non-β-catenin-dependent), both of which play an important role in regulating the balance between bone formation and bone resorption. Therefore, this review systematically describes the effects of abnormal Wnt pathway signaling on bone homeostasis under hyperglycemia, hoping to reveal the relationship between Wnt signaling and diabetic osteoporosis to further improve understanding of this disease.

Ca 2+/Calmodulin-dependent Protein Kinase II Inhibitor KN-93 Enhances Chondrogenesis of Bone Marrow Mesenchymal Stem Cells and Delays Chondrogenic Hypertrophy. In Vivo 2023; 37:667-678. [PMID: 36881077 PMCID: PMC10026659 DOI: 10.21873/invivo.13127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2023] [Revised: 02/04/2023] [Accepted: 02/09/2023] [Indexed: 03/08/2023]
Abstract
BACKGROUND/AIM Cartilage tissue engineering has been popularly applied in the treatment of articular cartilage defect because it is more effective in generating functional engineered cartilage than traditional methods. Although the chondrogenic differentiation of human bone marrow-derived mesenchymal stem cells (BM-MSCs) is well established, it is often accompanied by undesired hypertrophy. Ca2+/calmodulin-dependent protein kinase II (CaMKII) is a crucial mediator in the ion channel pathway which is known to be involved in chondrogenic hypertrophy. Therefore, this study aimed to reduce the hypertrophy of BM-MSCs by inhibiting CaMKII activation. MATERIALS AND METHODS BM-MSCs were cultured in three-dimensional (3D) scaffold under chondrogenic induction with and without CaMKII inhibitor, KN-93. After cultivation, markers of chondrogenesis and hypertrophy were investigated. RESULTS KN-93 at a concentration of 2.0 μM had no effect on the viability of BM-MSCs, while the activation of CaMKII was suppressed. A long period of KN-93 treatment significantly up-regulated the expression of SRY-box transcription factor 9 and aggrecan on day 28 compared to untreated BM-MSCs. Furthermore, KN-93 treatment significantly down-regulated the expression of RUNX family transcription factor 2 and collagen type X alpha 1 chain on days 21 and 28. Immunohistochemistry showed increased expression of aggrecan and type II collagen while the expression of type X collagen was reduced. CONCLUSION A CaMKII inhibitor, KN-93 is able to enhance chondrogenesis of BM-MSCs and suppress chondrogenic hypertrophy, suggesting its potential applicability in cartilage tissue engineering.

Abstract
The aim of the present study was to determine the effects of the Ca2+/calmodulin‑dependent protein kinase pathway inhibitor KN93 on osteoclastogenesis. RAW264.7 cells were incubated with macrophage colony‑stimulating factor (M‑CSF) + receptor activator of nuclear factor kappa‑light‑chain‑enhancer of activated B cells ligand (RANKL) to stimulate osteoclastogenesis and then treated with 10 µM KN93. The methods included tartrate‑resistant acid phosphatase (TRAP) staining, bone resorption activity assays, filamentous (F)‑actin staining, determination of intracellular calcium ([Ca2+]i) levels, monitoring of osteoclast‑specific gene expression levels and measurement of key transcription factors protein levels. The results suggested that KN93 inhibited the formation of TRAP‑positive multinucleated cells, shaping of F‑actin rings and resorption activity of the cells. In addition, KN93 decreased the concentration of [Ca2+]i, expression levels of osteoclast specific genes and protein levels of critical transcription factors in the M‑CSF + RANKL‑induced osteoclast model. In summary, KN93 may directly affect the differentiation and activation of osteoclasts, potentially through the Ca2+/calmodulin‑dependent protein kinase signaling pathway.

Abstract
Many cellular functions are regulated by calcium (Ca2+) signals that are generated by different signaling pathways. One of these is the inositol 1,4,5-trisphosphate/calcium (InsP3/Ca2+) signaling pathway that operates through either primary or modulatory mechanisms. In its primary role, it generates the Ca2+ that acts directly to control processes such as metabolism, secretion, fertilization, proliferation, and smooth muscle contraction. Its modulatory role occurs in excitable cells where it modulates the primary Ca2+ signal generated by the entry of Ca2+ through voltage-operated channels that releases Ca2+ from ryanodine receptors (RYRs) on the internal stores. In carrying out this modulatory role, the InsP3/Ca2+ signaling pathway induces subtle changes in the generation and function of the voltage-dependent primary Ca2+ signal. Changes in the nature of both the primary and modulatory roles of InsP3/Ca2+ signaling are a contributory factor responsible for the onset of a large number human diseases.

Abstract
Porous Ti is considered to be an ideal graft material in orthopaedic and dental surgeries due to its similar spatial structures and mechanical properties to cancellous bone. In this work, to overcome the bioinertia of Ti, Ta-implanted entangled porous titanium (EPT) was constructed by plasma immersion ion implantation &deposition (PIII&D) method. Ca-implanted and unimplanted EPTs were investigated as control groups. Although no difference was found in surface topography and mechanical performances, both Ca- and Ta-implanted groups had better effects in promoting MG-63 cell viability, proliferation, differentiation, and mineralization than those of unimplanted group. The expression of osteogenic-related markers examined by qRT-PCR and western blotting was upregulated in Ca- and Ta-implanted groups. Moreover, Ta-implanted EPT group could reach a higher level of these effects than that of Ca-implanted group. Enhanced osseointegration of both Ca- and Ta-implanted EPT implants was demonstrated through in vivo experiments, including micro-CT evaluation, push-out test, sequential fluorescent labeling and histological observation. However, the Ta-implanted group possessed more stable and continuous osteogenic activity. Our results suggest that Ta-implanted EPT can be developed as one of the highly efficient graft material for bone reconstruction situations.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2015; 8:5981-5987.

Abstract
AIMS The purpose of the study is to observe the functions of calcium/calmodulin dependent protein kinase II (CaMKII) in the induced chondrogenic differentiation of bone marrow derived mesenchymal stem cells (BMSCs). METHODS BMSCs was in vitro isolated and cultured for induced chondrogenesis. Western blot was used to ascertain the expression of CaMKII and phosphorylated CaMKII (PCaMKII, activatory CaMKII) in chondrogenic induced BMSCs. MTT method was utilized to observe the impact of CaMKII on the proliferation of BMSCs. The generation of cartilage matrix in BMSCs cells was detected by toluidine blue staining. The levels of cartilage marker genes COL2A1, Aggrecan and SOX9 in BMSCs were gained by real-time fluorescence quantitative polymerase chain reaction (RT-QPCR). Finally, BMSCs proliferation, cartilage matrix generation and the changes of COL2A1, Aggrecan and SOX9 were surveyed after CaMKII being blocked by CaMKII inhibitor KN93. RESULTS Expression of CaMKII and PCaMKII could be found in chondrogenic induced BMSCs. CaMKII had no significant influence on BMSCs proliferation, but the toluidine blue staining was obviously lighter, indicating a significant decline in the expression of COL2A1, Aggrecan and SOX9. CONCLUSION As one of the factors influencing the chondrogenic capacity of BMSCs, CaMKII does not impact on BMSCs proliferation, but it can inhibit the chondrogenic ability of BMSCs by influencing its differentiation.
