https://www.selleckchem.com/products/way-309236-a.html Aseptic loosening caused by periprosthetic osteolysis (PPO) is the main reason for the primary artificial joint replacement. Inhibition of inflammatory osteolysis has become the main target of drug therapy for prosthesis loosening. MiR-106b is a newly discovered miRNA that plays an important role in tumour biology, inflammation and the regulation of bone mass. In this study, we analysed the in vivo effect of miR-106b on wear debris-induced PPO. A rat implant loosening model was established. The rats were then administrated a lentivirus-mediated miR-106b inhibitor, miR-106b mimics or an equivalent volume of PBS by tail vein injection. The expression levels of miR-106b were analysed by real-time PCR. Morphological changes in the distal femurs were assessed via micro-CT and histopathological analysis, and cytokine expression levels were examined via immunohistochemical staining and ELISA. The results showed that treatment with the miR-106b inhibitor markedly suppressed the expression of miR-106b in distal femur and alleviated titanium particle-induced osteolysis and bone loss. Moreover, the miR-106b inhibitor decreased TRAP-positive cell numbers and suppressed osteoclast formation, in addition to promoting the activity of osteoblasts and increasing bone formation. MiR-106b inhibition also significantly regulated macrophage polarization and decreased the inflammatory response as compared to the control group. Furthermore, miR-106b inhibition blocked the activation of the PTEN/PI3K/AKT and NF-κB signalling pathways. Our findings indicated that miR-106b inhibition suppresses wear particles-induced osteolysis and bone destruction and thus may serve as a potential therapy for PPO and aseptic loosening.Background Cerebral malaria (CM) is the most severe complication in malaria. Endothelial activation, cytokine release and vascular obstruction are essential hallmarks of CM. Clinical studies have suggested a link between v
