Taken together, our results indicate that Tablysin-15 significantly suppresses osteoclastogenesis in vitro and in vivo, thus it might be a excellent candidate for treating osteolytic-related diseases.Alcoholic liver disease (ALD) is a progressively aggravated liver disease with high incidence in alcoholics. Ethanol-induced fat accumulation and the subsequent lipopolysaccharide (LPS)-driven inflammation bring liver from reversible steatosis, to irreversible hepatitis, fibrosis, cirrhosis, and even hepatocellular carcinoma. Peroxisome proliferator-activated receptor α (PPARα) is a member of the nuclear receptor superfamily of ligand-activated transcription factors and plays pivotal roles in the regulation of fatty acid homeostasis as well as the inflammation control in the liver. It has been well documented that PPARα activity and/or expression are downregulated in liver of mice exposed to ethanol, which is thought to be one of the prime contributors to ethanol-induced steatosis, hepatitis and fibrosis. This article summarizes the current evidences from in vitro and animal models for the critical roles of PPARα in the onset and progression of ALD. Importantly, it should be noted that the expression of PPARα in human liver is reported to be similar to that in mice, and PPARα expression is downregulated in the liver of patients with nonalcoholic fatty liver disease (NAFLD), a disease sharing many similarities with ALD. Therefore, clinical trials investigating the expression of PPARα in the liver of ALD patients and the efficacy of strong PPARα agonists for the prevention and treatment of ALD are warranted.The aim of the study was to synthesize a new series of benzimidazole derivatives and to investigate the underlying molecular mechanisms of the potential cell cycle inhibition and apoptotic effects against a panel of selected human cancer cell lines along with HEK-293 human embryonic kidney cells. NIK SMI1 MTT assay was used to evaluate cytotoxic effects. Muse™ Cell Analyzer was used to assess cell cycle progression. Annexin-V/PI staining assay was used for detecting apoptosis. All the synthesized compounds showed a significant cytotoxic effect against cancer cells with the IC50 values between 9.2 and 166.1 μg/mL. Among the tested derivatives, compound 5 showed significant cytotoxic activity against MCF-7, DU-145 and H69AR cancer cells with the IC50 values of 17.8 ± 0.24, 10.2 ± 1.4 and 49.9 ± 0.22 μg/mL respectively. The compounds 5 was also tested on HEK-293 human embryonic kidney cells and found to be safer with lesser cytotoxicity. The results revealed that compound 5 significantly increased cell population in the G2/M-phase which is modulated by a p53 independent mechanism. Compound 5 caused an increase in the percentage of late apoptotic cells in all tested cancer cells in a concentration-dependent manner. Among all synthesized derivatives, compound 5 the bromo-derivative, showed the highest cytotoxic potential, induced G2/M cell cycle arrest and apoptotic cell death in genotypically different human cancer cells. These results suggest that compound 5 might be a promising agent for cancer therapy and further structural modifications of benzimidazole derivatives may create promising anticancer agents.Differential expression of metabolic detoxification enzymes is an important mechanism involved in pesticide/acaricide resistance of mite pests. The competing endogenous RNA hypothesis offers a new opportunity to investigate post-transcriptional regulation of those genes. In this study, 4454 long non-coding RNAs were identified in the carmine spider mite Tetranychus cinnabarinus by transcriptome sequencing. Software-based predictions indicated that a long intergenic non-coding RNA, (lincRNA)_Tc13743.2 and a detoxification enzyme gene, TcGSTm02, both contained a microRNA (miR-133-5p) response element. Over-expression of lincRNA_Tc13743.2 and TcGSTm02 were detected in a cyflumetofen-resistant T. cinnabarinus strain (CyR), whereas down-regulation of miR-133-5p was observed in this strain. Conversely, up-regulation of miR-133-5p could inhibit TcGSTm02 expression levels, and both lincRNA_Tc13743.2 and TcGSTm02 were significantly enriched in miR-133-5p biotin-avidin pull-down assays. RNA-binding protein immunoprecipitation assay showed that lincRNA_Tc13743.2 and TcGSTm02 bound to a silencing complex containing miR-133-5p. Moreover, a luciferase reporter assay based on a human cell line revealed that over-expression of lincRNA_Tc13743.2 could significantly reduce the inhibition exerted by miR-133-5p through the TcGSTm02 3'UTR. In addition, co-localization of lincRNA_Tc13743.2 and miR-133-5p was detected using fluorescence in situ hybridization, suggesting that lincRNA_Tc13743.2 interacts directly with miR-133-5p in spider mites. More importantly, silencing the expression of lincRNA_Tc13743.2 significantly reduced the expression levels of TcGSTm02 and increased the sensitivity of spider mites to cyflumetofen. Our data show that lincRNA_Tc13743.2 up-regulates TcGSTm02 expression by competing for miR-133-5p binding, demonstrating that a lincRNA_Tc13743.2-miR-133-5p-TcGSTm02 pathway mediates cyflumetofen resistance in mites.Sequence analysis of the genomic DNA isolated from four biotypes of the soybean aphid, Aphis glycines (AG), revealed that in addition to the commonly observed retrovirus-related retrotransposons, viral sequences derived from multiple RNA and DNA viruses have integrated into the genome. Notably, sequences of more than 60 nudiviral genes were identified from de novo assembled DNA contigs, and mapped to assembled genomic scaffolds of AG, indicating that an ancient nudivirus, named Aphis glycines endogenous nudivirus (AgENV), had integrated into the AG genome. Furthermore, sequences derived from a similar endogenous nudivirus, Melanaphis sacchari endogenous nudivirus (MsENV), were identified from the genomic scaffolds of the sugarcane aphid, Melanaphis sacchari. Analysis of transcriptome and small RNA sequence data derived from AG did not provide evidence for transcription of the integrated AgENV genes. Hence, the genes of AgENV may be present as pseudogenes. Phylogenetic analysis based on nudivirus core genes indicated that these aphid ENVs belong to the genus Alphanudivirus.
