Essential Role involving Non-Coding RNAs within Enterovirus Infection: Through Basic Elements to Clinical Prospective customers.
Raman SERS was employed to understand the difference in the protein upon surface modification. The anti-HIV property of the particles was confirmed in-vitro. The modified device demonstrated acceptable nanoparticle properties with controlled release and higher effective concentration in the area of infection. The increasing prevalence of fungal infections coupled with emerging drug resistance has stimulated an urgent need to explore new and effective antifungal agents. Sanguinarine and chelerythrine constitute alkaloids that have exhibited antifungal activities. However, the effects of a 11 mixture of these agents against Candida albicans and Cryptococcus neoformans have remained largely unexplored. The purpose of this study was to assess the anti-fungal and anti-biofilm efficacy of combined chelerythrine-sanguinarine against C. albicans and C. neoformans in vitro. Combined chelerythrine-sanguinarine inhibited C. albicans and C. JW74 neoformans growth with minimum inhibitory concentrations (MICs) of 2 and 16 μg/mL, respectively, and effectively inhibited adhesion and biofilm formation of these pathogens at minimum biofilm inhibitory concentrations of 1 and 8 μg/mL. Notably, the mixture significantly eradicated mature C. albicans and C. neoformans biofilms at 8 and 128 μg/mL, respectively. In particular, the mixture was found to disrupt cell membrane integrity and enhance penetration of antibiotics into fungal cells, suggesting its antifungal mode of action. Hence, combined chelerythrine-sanguinarine shows promise as a potential anti-fungal and anti-biofilm agent for the management of serious infections caused by C. albicans and C. neoformans. We have reported that of the 10 most commonly used adeno-associated virus (AAV) serotype vectors, AAV6 is the most efficient in transducing primary human hematopoietic stem cells (HSCs) in vitro, as well as in vivo. More recently, polyvinyl alcohol (PVA), was reported to be a superior replacement for human serum albumin (HSA) for ex vivo expansion of HSCs. Since HSA has been shown to increase the transduction efficiency of AAV serotype vectors, we evaluated whether PVA could also enhance the transduction efficiency of AAV6 vectors in primary human HSCs. We report here that up to 12-fold enhancement in the transduction efficiency of AAV6 vectors can be achieved in primary human HSCs with PVA. We also demonstrate that the improvement in the transduction efficiency is due to PVA-mediated improved entry and intracellular trafficking of AAV6 vectors in human hematopoietic cells in vitro, as well as in murine hepatocytes in vivo. Taken together, our studies suggest that the use of PVA is an attractive strategy to further improve the efficacy of AAV6 vectors. This has important implications in the optimal use of these vectors in the potential gene therapy and genome editing for human hemoglobinopathies such as β-thalassemia and sickle cell disease. Recently, the long noncoding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) was reported to be involved in the pathogenesis of several cancers, including human colorectal cancer (CRC). However, the molecular basis for cancer initiation, development, and progression remains unclear. In this study, we observe that upregulated PVT1 is associated with poor prognosis and bad clinicopathological features of CRC patients. In vitro means of PVT1 loss in a CRC cell line inhibit cell proliferation, migration, and invasion. Furthermore, dual-luciferase reporter and RNA pull-down assays indicated that PVT1 binds to miR-16-5p, which has been shown to play strong tumor suppressive roles in CRC. Targeted loss of miR-16-5p partially rescues the suppressive effect induced by PVT1 knockdown. Vascular endothelial growth factor A (VEGFA), a direct downstream target of miR-16-5p, was suppressed by PVT1 knockdown in CRC cells. Overexpression of VEGFA is known to modulate the AKT signaling cascade by activating vascular endothelial growth factor receptor 1 (VEGFR1). We, therefore, show that PVT1 loss combined with miR-16-5p overexpression reduces tumor volume maximally when propagated within a mouse xenograft model. We conclude that the PVT1-miR-16-5p/VEGFA/VEGFR1/AKT axis directly coordinates the response in CRC pathogenesis and suggest PVT1 as a novel target for potential CRC therapy. BACKGROUND Caffeine, alcohol, nicotine and cannabis are commonly used psychoactive substances. While the use of these substances has been previously shown to be genetically correlated, causality between these substance use traits remains unclear. We aimed to revisit the genetic relationships among different measures of SU using genome-wide association study (GWAS) summary statistics from the UK Biobank, International Cannabis Consortium, and GWAS & Sequencing Consortium of Alcohol and Nicotine use. METHODS We obtained GWAS summary statistics from the aforementioned consortia for ten substance use traits including various measures of alcohol consumption, caffeine consumption, cannabis initiation and smoking behaviours. We then conducted SNP-heritability (h2) estimation for individual SU traits, followed by genetic correlation analyses and two-sample Mendelian randomisation (MR) studies between substance use trait pairs. RESULTS SNP h2 of the ten traits ranged from 0.03 to 0.11. After multiple testing correction, 29 of the 45 trait pairs showed evidence of being genetically correlated. MR analyses revealed that most SU traits were not causally associated with each other. However, we found evidence for an MR association between regular smoking initiation and caffeine consumption 40.17 mg; 95 % CI [24.01, 56.33] increase in caffeine intake per doubling of odds in smoking initiation). Our findings were robust against horizontal pleiotropy, SNP-outliers, and the direction of causality was consistent in all MR analyses. CONCLUSIONS Most of the substance traits were genetically correlated but there is little evidence to establish causality apart from the relationship between smoking initiation and caffeine consumption. Intravascular thrombosis is a main cause of multiple cardiovascular diseases. A high thrombolytic activity of the microbial fibrinolytic enzyme Subtilisin QK-2, which is highly homologous to Nattokinase, shows great exploitable potential in thrombolytic therapy. However, the lack of a sensitive detection method limits the further analysis of Subtilisin QK-2 in vivo. We prepared a polyclonal antibody and four monoclonal antibodies (IgG1, titers of 1500,000) to establish a sensitive sandwich ELISA for Subtilisin QK-2 detection. The limit of detection (LOD) of this ELISA was 1.160 ng/mL. The linear range of the standard curve was 1.96-250 ng/mL (R2 = 0.9912). The cut-off value was 0.236. Subsequently, a pharmacokinetic dose (IV bolus) was administered and analyzed with the established ELISA. The concentration-time profiles were best fitted to a two-compartment model. T1/2α values for doses of 2 mg/kg, 4 mg/kg, and 8 mg/kg were 29.90 ± 10.02 min, 27.17 ± 1.96 min, and 21.83 ± 9.95 min, and T1/2β values were 144.43 ± 49.
