the diagnosis and assessment of CHD-PAH.The aim of the present study was to investigate the role of microRNA (miR)-29b in the proliferation and migration of bone marrow mesenchymal stem cells (BMSCs) in rats with castration-induced osteoporosis and the relevant mechanisms. The gene expression profiling microarray technique was utilized to sequence the BMSCs with overexpressed miR-29b. BAY876 The intersection of the potential targets and the genes downregulated in the sequencing were utilized for GO enrichment analysis. Gene set enrichment analysis (GSEA) was employed to analyze the effect of miR-29b on signaling pathways. Additionally, the effects of miR-29b overexpression on the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) and transforming growth factor-β (TGF-β)/Drosophila mothers against decapentaplegic protein (Smad) signaling pathways were detected via RT-qPCR assay and western blotting. The expression level of miR-29b was found to be significantly reduced in bone marrow tissues of postmenopausal osteoporosis patients and BMSCs of rats the proliferation and migration ability of BMSCs in rats with castration-induced osteoporosis, and such an enhancement may be correlated with the activation of the PI3K/AKT and TGF-β/Smad signaling pathways.Orthodontic-induced root resorption is a severe side effect that can lead to tooth root shortening and loss. Compressive force induces tissue stress in the cementum that covers the tooth root, which is associated with activation of bone metabolism and cementum resorption. To investigate the role of cementocytes in mechanotransduction and osteoclast differentiation, the present study established an in vitro three-dimensional (3D) model replicating cellular cementum and observed the effects of static compression on the cellular behavior of the cementocytes. Cell Counting Kit-8 assay, alkaline phosphatase staining and dentin matrix protein 1 quantification were used to evaluate the cementocyte differentiation in the 3D scaffolds. Cellular viability under static compression was evaluated using live/dead staining, and expression of mineral metabolism-related genes were analyzed via reverse transcription-quantitative PCR. The results suggested that the cementocytes maintained their phenotype and increased the expression of osteoprotegerin (OPG), receptor activator of NF-κB ligand (RANKL) and sclerostin (SOST) in the 3D model compared with cells cultured in two dimensions. Compression force increased cell death and induced osteoclastic differentiation via the upregulation of SOST and RANKL/OPG ratio, and the downregulation of osteocalcin. The effect of compression showed a force magnitude-dependent pattern. The present study established an in vitro model of cellular cementum to study the biology of cementocytes. The results indicated that cementocytes are sensitive to mechanical loading and may serve potential roles in the metabolic regulation of minerals during orthodontic root resorption. These findings provide a novel tool to study biological processes in the field of orthodontics and expand knowledge of the biological function of cementocytes.The aim of present study was to evaluate the potential effects of Rhodiola crenulata oral liquid (RCOL) on exhaustive exercise (EE)-induced fatigue in mice. Male Institute of Cancer Research mice from five treatment groups (n=10 per group) were orally administered with sterilized water for the Control and EE groups and/or RCOL at doses of 1.02, 3.03 and 6.06 ml/kg/day, once daily for 2 weeks. Anti-fatigue activity was subsequently evaluated by measuring the levels of creatine kinase (CK), lactic acid (LA), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and total anti-oxidative capability (T-AOC). Histopathology was assessed using hematoxylin and eosin staining. Ultrastructures of mitochondria were observed by transmission electron microscopy. Energy supply capacity was assessed using citrate synthase (CS), succinate dehydrogenase (SDH), Na+-K+-ATPase, and liver and quadriceps glycogen content assays. Expression levels of mRNA and protein associated with mitophagociated with increased antioxidant activity, enhanced energy production and the inhibition of mitophagy by suppressing the PINK1/Parkin signaling pathway.The majority of deaths among patients with prostate cancer (PCa) occur following metastasis; therefore, there is a critical need for effective treatment of metastatic PCa. Epithelial-mesenchymal transition (EMT) is vital in the early stage of cancer cell metastasis and CD147 has been reported to be associated with various types of cancer. The goal of this study was to investigate the role of CD147 in the EMT of PCa cells via short hairpin (sh)RNA-mediated knockdown of CD147 in lymph node carcinoma of the prostate (LNCaP) cells. Reverse transcription-quantitative PCR and western blotting were performed to examine gene and protein expression. Cell migration and invasion were detected using a Transwell assay. Cell Counting Kit-8 assay was performed to investigate cell viability. The knockdown of CD147 in LNCaP cells (LNCaP/shCD147 cells) resulted in an increase in the expression of E-cadherin (an epithelial marker), and a decrease in the expression of N-cadherin and vimentin (mesenchymal markers). Importantly, the downregulation of CD147 in LNCaP cells inhibited the expression levels of nuclear β-catenin and Snail, and phosphorylation of glycogen synthase kinase (GSK)-3β on Ser 9, and increased the expression of phosphorylated (p)-β-catenin (Ser33/37/Thr41). Treatment with lithium chloride (LiCl), a Wnt/β-catenin pathway agonist or a GSK-3β inhibitor, attenuated CD147 downregulation-induced p-β-catenin (Ser33/37/Thr41) expression, which resulted in the upregulation of β-catenin in the nucleus. LiCl treatment prompted β-catenin-mediated expression of target proteins such as Snail and vimentin in LNCaP/shCD147 cells, and prevented E-cadherin expression, a molecule downstream to Snail. In conclusion, these findings revealed an important role of CD147 in the regulation of the invasive and metastatic potential of PCa cells. CD147, via modulation of the Wnt/β-catenin pathway, may be implicated in the regulation of EMT of PCa cells and could be a potential therapeutic target for PCa.
