A series of benzo[b]furan derivatives having a five-membered heterocyclic substituent at the 2-position were prepared from 2-(1-chloro-2-formylvinyl)benzo[b]furans (2) and 2-(4-alkylcarbamoylbuta-1,3-dienyl)benzo[b]furans. These 2-heterocyclic benzo[b]furans were evaluated for their cysteinyl leukotriene receptor (cysLT1, cysLT2) inhibitory activity. Several compounds showed moderate inhibition...
Methods We introduced Vpu start codon mutation and point substitution in p17 Gag matrix (L30E) in HIV-1 pNLAD8 through PCR. Progeny viruses were produced in two cell-types: 293T and HeLa by transfection. Infectivity potential of Vpu+/Vpuviruses carrying Gag (L30E) mutation was assessed in TZM-bl cell line and their replication potential in peripheral blood mononuclear cells (PBMC) and monocyte-...
Hepatitis C virus (HCV) is a human hepatotropic virus, but the relevant host factors restricting HCV infection to hepatocytes are only partially understood. We demonstrate that exogenous expression of defined host factors reconstituted the entire HCV life cycle in human nonhepatic 293T cells. This study shows robust HCV entry, RNA replication, and production of infectious virus in human nonhepa...
Pseudoviruses are useful surrogates for highly pathogenic viruses because of their safety, genetic stability, and scalability screening assays. Many different pseudovirus platforms exist, each with advantages limitations. Here we report our efforts to optimize characterize an HIV-based lentiviral assay neutralizing antibodies SARS-CoV-2 using a stable 293T cell line expressing human angiotensin...
هدف: هدف از این مطالعه بررسی تاثیر DJ-1 بر افزایش بقای سلولهای دوپامین ساز در برابر سمیت پارکینسونی میباشد. مواد و روشها: ابتدا لنتی ویروسهای نوترکیب ناقل توام ژن های DJ-1 و گزارشگر Jred تولید شده و برای آلوده سازی سلولها استفاده شدند. بدین منظور سه پلاسمید لنتی ویروسی بهنامهای ناقل، بسته بندی و غشا برای ترانسفکشن سلولهای HEK-293T بهعنوان رده سلولی...
ABCC4 encodes multidrug resistance protein 4 (MRP4), a member of the ATP-binding cassette family of membrane transporters involved in the efflux of endogenous and xenobiotic molecules. The aims of this study were to identify single nucleotide polymorphisms of ABCC4 and to functionally characterize selected nonsynonymous variants. Resequencing was performed in a large ethnically diverse populati...
The ectopic activation of NR0B1 is involved in the development of some cancers. However, the regulatory mechanisms controlling NR0B1 expression are not well understood. Therefore, the epigenetic modifications promoting NR0B1 activation were examined in this study. NR0B1 protein was detected in cancerous tissues of more than 50% of human lung adenocarcinoma (ADCA) cases and tended to be expresse...
Hydrogen peroxide is currently the most widely used apoptosis inducer due to its broad cytotoxic efficacy against nearly all cell types. However, equivalent cytotoxicity is achieved over a wide range of doses, although the reasons for this differential sensitivity are not always clear. In this study, three kinds of cells, the 293T cell line, primary fibroblasts, and terminally differentiated my...
Streptozotocin (STZ) is a diabetogenic agent extensively used to induce diabetes and to study complications including diabetic peripheral neuropathy (DPN). While studying the influence of transient receptor potential vanilloid 1 (TRPV1) on DPN in the STZ-induced diabetic mouse model, we found that a proportion of STZ-treated mice was nondiabetic but still exhibited hyperalgesia. To understand t...
