Abstract MicroRNAs are a class of small noncoding RNAs that function as critical gene regulators through targeting mRNAs for translational repression or degradation. In this study, we showed that the miR-133b expression level was decreased while the Sirt1 mRNA expression level was increased in osteosarcoma tissue and cell lines. A low expression of miR-133b was significantly associated with tumor size, distant metastasis, and advanced clinical stage. In addition, osteosarcoma patients with a low miR-133b expression showed a worse prognosis when compared to those with a high level of miR-133b expression. Thus, we identified Sirt1 as a More >

Abstract Although increasing evidence indicates that the deregulation of microRNAs (miRNAs) contributes to tumorigenesis and invasion, little is known about the role of miR-133b in human non-small cell lung cancer (NSCLC). In the present study, we revealed that the introduction of miR-133b dramatically suppressed NSCLC cell growth, migration, and invasion in vitro. On the contrary, miR-133b inhibitors promoted cell growth, migration, and invasion in vitro. Further studies revealed that matrix metallopeptidase 9 (MMP9) is a direct target gene of miR-133b. Silencing MMP9 inhibited cell growth, migration, and invasion of NSCLC cells, which was consistent with the More >

Abstract Excessive fat ectopically deposited in the non-adipose tissues is considered as one of the leading causes of myopathy. The aim of this study was to investigate the role of Dihydroartemisinin (DHA) in palmitate (PAL)-incubated H9c2 cells (lipotoxicity-induced cell injury model). Cell viability of PAL-treated cells was determined by MTT assay, and apoptotic regulators were examined by qRT-PCR and western blot analysis, in the absence or in the presence of DHA, respectively. Expression levels of miR-133b and Sirt1 were also evaluated by qRT-PCR and western blotting examination. PAL decreased the viability of H9c2 cells and enhanced More >
