Abstract
MicroRNAs (miRNAs) as a class of small noncoding RNA molecules regulate the expression of targeted gene. The dysregulation of microRNAs is reported to be involved in carcinogenesis and tumor progression. Here, we identified miR-140-3p as a downregulated microRNA in most cancer tissues including lung cancer tissues, compared with their normal counterparts. MiR-140-3p was observed to perform its tumor suppressor function via its inhibition on cell growth, migration and invasion but its induction of cell apoptosis. Furthermore, the growth of non-small-cell lung cancer (NSCLC) cells in nude mouse models were suppressed by overexpression of miR-140-3p. ATP8A1 was demonstrated as a novel direct target of miR-140-3p using a luciferase assay. The increased level of intracellular ATP8A1 protein attenuated the inhibitor role of miR-140-3p in the growth and mobility of NSCLC cell. A regulation mechanism of miR-140-3p for the development and progression of NSCLC through downregulating the ATP8A1 expression was first discovered in the present study.

Abstract
The fast response to stimuli and subsequent activation of the nuclear factor of activated T cells (NFAT) signaling pathway play an essential role in human T cell functions. MicroRNAs (miRNAs) are increasingly implicated in regulation of numerous biological and pathological processes. In this study we demonstrate a novel function of miRNA-9 (miR-9) in regulation of the NFAT signaling pathway. Upon PMA-ionomycin stimulation, miR-9 was markedly increased, consistent with NFAT activation. Overexpression of miR-9 significantly enhanced NFAT activity and accelerated NFAT dephosphorylation and its nuclear translocation in response to PMA-ionomycin. Karyopherin-β1 (KPNB1, a nucleocytoplasmic transporter) and dual-specificity tyrosine phosphorylation-regulated kinase 1B (DYRK1B) were identified as direct targets of miR-9. Functionally, miR-9 promoted IL-2 production in stimulated human lymphocyte Jurkat T cells. Collectively, our data reveal a novel role for miR-9 in regulation of the NFAT pathway by targeting KPNB1 and DYRK1B.

Abstract
Osteoarthritis (OA) is a common degenerative joint disease, the pathological mechanism of which is currently unknown. Genetic alteration is one of the key contributing factors for OA pathology. Recent evidence suggests that epigenetic and microRNA regulation of critical genes may contribute to OA development. In this article, we review the epigenetic and microRNA regulations of genes related to OA development. Potential therapeutic strategies may be developed on the basis of novel findings.

Abstract
microRNAs (miRNAs) regulate gene expression mainly at the posttranscriptional level. Many different miRNAs are expressed in chondrocytes, and each individual miRNA can regulate hundreds of target genes, creating a complex gene regulatory network. Experimental evidence suggests that miRNAs play significant roles in various aspects of cartilage development, homeostasis, and pathology. The possibility that miRNAs can be novel therapeutic targets for cartilage diseases led to vigorous investigations to understand the role of individual miRNAs in skeletal tissues. Here, we summarize our current understanding of miRNAs in chondrocytes and cartilage. In the first part, we discuss roles of miRNAs in growth plate development and chondrocyte differentiation. In the second part, we put a particular focus on articular cartilage and discuss the significance of variety of findings in the context of osteoarthritis, the most common degenerative joint disease.
