Objective(s): Study and development of antifouling nanosystem for conjugation of drugs were attracting great attention in recent years. The present study aimed to develop novel curcumin-loaded silica nanoparticles containing zwitterionic coating as an antifouling system to provide protein corona free nanoformulations for curcumin. Materials and Methods: Silica nanoparticles were prepared ...

Backgrounds: Most of the hepatitis C virus (HCV) infections elicit poor immune responses and 75% to 85% of cases become chronic therefore, the development of an effective vaccine against HCV is of paramount importance. In this study, we aimed to evaluate co-administration of HCV non-Structural Protein 2 and IL-12 DNA vaccines in C57BL/6 mice. Methods: A plasmid encoding full-length HCV NS2 prot...

Changes in protein-protein interactions that occur in response to environmental cues are difficult to uncover and have been poorly characterized to date. Here we describe a yeast-based assay that allows many binary protein interactions to be assessed in parallel and under various conditions. This method combines molecular bar-coding and tag array technology with the murine dihydrofolate reducta...

We describe a new method used for quantitating weak interactions between proteins in which the weak interaction is "assisted" by a known DNA-DNA interaction. Oligonucleotides, which are conjugated to proteins of interest, contain short complementary DNA sequences that provide additional binding energy for protein-protein interactions. A stretch of unpaired bases links the protein to the hybridi...

Background: Mammalian Cell lines are the main expression system for the production of recombinant therapeutic proteins. Optimization of cell culture condition is performed via alteration in different parameter. Cell culture media plays an important role in cell cycle because of compounds such as amino acids, vitamins, inorganic salts, glucose, and serum as a source of growth factors, trace elem...

A gel mobility retardation assay can be used to detect a protein-protein interaction. The assay is based on the electrophoretic mobility of a protein-protein complex being less than that of either protein alone. Electrophoretic mobility is detected by the fluorescence of a green fluorescent protein variant that is fused to one of the protein partners. The assay is demonstrated by using the inte...

Objective : The anti-tumor effect of the beta-adrenergic receptor antagonist propranolol in breast cancer is well known; however, its activity glioblastoma not well-evaluated. Notch-Hes pathway known to regulate cell differentiation, proliferation, and apoptosis. We investigated human lines, role Notch Hes signaling this process.Methods performed immunohistochemical staining on 31 surgically re...

Purpose: To determine the effect of procyanidin A1 (PCA1) on sepsis.Methods: Dulbecco’s Modified Eagle Medium (DMEM) was employed to incubate mouse hepatic cell line AML12. The AML12 cells treated with lipopolysaccharide (LPS, 50 μg/mL) used establish a sepsis model. Cell viability evaluated using CCK-8 assay, while apoptosis assessed by flow cytometry. Aspartate transaminase (AST), alanine ami...
