Sweets recognition and also protein-protein connection associated with mammalian lectins conferring different capabilities.
Moreover, the levels of proinflammatory cytokines and chemokines and cyclo-oxygenase COX-2 enzyme were also more significantly reduced by Carnosine+HA and FidHycarn compared to carnosine alone. However, interestingly, in some cases, the effects of FidHycarn were more important than Carnosine+HA association and not statistically different to methotrexate (MTX) used as positive control. Thus, the conjugation of Carnosine with HA (FidHycarn) could represent an interesting therapeutic strategy to combat arthritis disorders. Long noncoding RNAs lncRNAs play an essential role in the epigenetic regulation of colorectal cancer CRC. However, the biological function of lncRNA Long Intergenic Noncoding RNA 00511 LINC00511 in the CRC is unclear. Here, BRM/BRG1 ATP Inhibitor-1 in vivo found that LINC00511 was significantly up-regulated in the CRC tissue samples and cell lines. Consistently, LINC00011 overexpression was correlated with larger tumor size and advanced tumor stage. Functionally, LINC00511 promoted the proliferation and reduced the apoptosis of CRC cells in vitro, and LINC00511 knockdown repressed tumor growth in vivo. Mechanistically, hypoxia-inducible factor 1α (HIF-1α) bound the promoter region of LINC00511 to active tits transcription. Moreover, LINC00511 functioned as the miR-153-5p sponge in the cytoplasmic portion, and miR-153-5p also targeted the 3'-UTR of HIF-1α. In conclusion, this study identifies the roles of LINC00511 in CRC progression and uncovers the positive feedback loop of HIF-1α/LINC00511/miR-153-5p in CRC, providing a potential therapeutic target. INTRODUCTION In recent decades, fine-dust particulate matter (FM) has become a potential health hazard, causing various pathological respiratory disorders around the world. Inflammation induced by FM is regarded as a major cause of respiratory disorder in humans. #link# The purpose of this study was to evaluate the therapeutic efficacy of Shibashin Misena®, a functional food composed of various bioactive ingredients, on FM-induced respiratory disorders in mice. MATERIALS AND METHODS Briefly, 40 mice were divided equally into four groups normal controls (NC); FM-induced control group (FC); FM group treated with Shibashin Misena® 0.1 mL/head/day (FM0.1); FM group treated with Shibashin Misena® 0.2 mL/head/day (FM0.2). RESULTS FM significantly induced TNF-α, IL-17A, IL-1β, and TGF-β in bronchoalveolar lavage fluid (BALF) collected from the FM mice. Compared with FC, Shibashin Misena® decreased TNF-α, IL-17A, and IL-1β levels in BALF, and histopathologic evaluations revealed that Shibashin Misena® treatment significantly reduced inflammatory-cell infiltration and fibrosis related collagen deposition in lung tissue. CONCLUSION This study demonstrated that Shibashin Misena® decreased FM-induced inflammation and fibrosis in lung tissue. Thus, Shibashin Misena® could be an effective supplement to prevent or improve FM-induced pulmonary disorders. Epithelial mesenchymal transition (EMT) is a critical step in cancer metastasis. Some evidences have been provided to verify up-regulation of linc00511 in multiple cancers and oncogenic roles during cancer malignant process. But, the roles of linc00511 on the metastasis of lung cancer are still largely unclear. Our study aims to reveal the functional effects of linc00511 on TGF-β1-induced EMT in lung cancer. Our results showed that knockdown of linc00511 significantly inhibited TGF-β1-induced migration and invasion and down-regulated the mRNA and protein levels of MMP2, MMP9 and MMP12 in TGF-β1 treated SPCA1 and H1975 cells. Also, western blotting results showed that inhibition of linc00511 remarkably suppressed TGF-β1-induced N-cadherin, Vimentin and snail and increased E-cadherin expression in SPCA1 and H1975 cells. Noteworthy, we further found that inhibition of linc00511 could down-regulate TGF-β1-induced ZEB2 mRNA and protein levels by sponging miR-183-5p in SPCA1 and H1975 cells. Taken together, our findings suggested knockdown linc00511 suppressed TGF-β1-induced migration and invasion via inhibiting EMT and MMPs in lung cancer cells. Sirtuin1 (SIRT1), a class III histone deacetylase, exerts a protective role against kidney injury. However, its functions in renal ischemia/reperfusion (I/R) injury remains unclear as yet. In this study, we established acute kidney injury (AKI) rat model through renal ischemia and reperfusion, and the role of SIRT1 in I/R-induced AKI was investigated both in vivo and in vitro. In in vivo study, SIRT1 was expressed in tubular epithelial cells (TECs) and its expression was upregulated after I/R treatment. Meanwhile, our in vitro experiment confirmed that the expression of SIRT1 was also elevated in human renal proximal tubular epithelial (HK2) cells treated with hypoxia and reoxygenation (H/R). Notably, activation of SIRT1 by resveratrol (Res, an activator of SIRT1) could significantly ameliorate renal function and reduce the TECs apoptosis in rats. Likewise, Res intervention also reduced the apoptosis and the production of reactive oxygen species in HK2 cells. Furthermore, we found that the autophagy level was upregulated in I/R injury, which could be raised further through resveratrol intervention; and chloroquine (CQ, an autophagy inhibitor) did reverse these protective effects of SIRT1 activation. Taken together, our results suggest that SIRT1 plays a protective role by autophagy induction in I/R- induced AKI. Its role might serve as a preventive approach in I/R-associated AKI. Hundreds of dominant-negative myosin mutations have been identified that lead to hypertrophic cardiomyopathy, and the biomechanical link between mutation and disease is heterogeneous across this patient population. To increase the therapeutic feasibility of treating this diverse genetic population, we investigated the ability of locked nucleic acid (LNA)-modified antisense oligonucleotides (ASOs) to selectively knock down mutant myosin transcripts by targeting single-nucleotide polymorphisms (SNPs) that were found to be common in the myosin heavy chain 7 (MYH7) gene. We identified three SNPs in MYH7 and designed ASO libraries to selectively target either the reference or alternate MYH7 sequence. We identified ASOs that selectively knocked down either the reference or alternate allele at all three SNP regions. We also show allele-selective knockdown in a mouse model that was humanized on one allele. These results suggest that SNP-targeting ASOs are a promising therapeutic modality for treating cardiac pathology.
