Expression Optimizing of Recombinant Oxalyl-CoA Decarboxylase in .

Background: One of the most common diseases of the urinary tract is stones of this system, including kidney stones. About 70%-80% of kidney stones are calcium oxalate. Oxalyl-CoA decarboxylase is a single polypeptide included of 568 amino acids which play a key role in oxalate degradation.

Recent Advances on Immune Targeted Therapy of Colorectal Cancer Using bi-Specific Antibodies and Therapeutic Vaccines.

Colorectal cancer (CRC) is a universal heterogeneous disease that is characterized by genetic and epigenetic alterations. Immunotherapy using monoclonal antibodies (mAb) and cancer vaccines are substitute strategies for CRC treatment. When cancer immunotherapy is combined with chemotherapy, surgery, and radiotherapy, the CRC treatment would become excessively efficient.

Designing a diagnostic kit for Oxalyl CoA Decarboxylase enzyme by ELISA method.

Urinary stones are the third most commonly reported urinary tract disease. Kidney stones are one of the most common types of urinary stones that most of them (70-80%) are calcium oxalate. Oxalic acid is highly oxidized organic compounds, which found in dietary and produced by the intestinal microflora.

Expression and production of recombinant scorpine as a potassium channel blocker protein in Escherichia coli.

Scorpine is a cationic protein from the venom of Pandinus imperator, belonging to potassium channel blocker family, which has been shown to have antibacterial, antiviral, and antiplasmodia activities. In the present study, a pET-44a vector containing scorpine synthetic gene with T7 Promoter (pET 44a-His6-Nus-His6-tev-scorpine) was transferred into Escherichia coli Rosetta-gami B (DE3) for soluble expression of the protein in the cytoplasm and its overproduction. After confirming recombinant scorpine peptide expression using SDS-PAGE and Western blot, augmentation of production was performed during two stages.

Targeted cancer therapy through antibody fragments-decorated nanomedicines.

Active targeting in cancer nanomedicine, for improved delivery of agents and diagnose, has been reviewed as a successful way for facilitating active uptake of theranostic agents by the tumor cells. The application of a targeting moiety in the targeted carrier complexes can play an important role in differentiating between tumor and healthy tissues. The pharmaceutical carriers, as main part of complexes, can be polymeric nanoparticles, micelles, liposomes, nanogels and carbon nanotubes.

High overexpression and purification of optimized bacterio-opsin from Halobacterium Salinarum R1 in E. coli.

The purple membrane of Halobacterium Salinarum carries out a protein, bacteriorhodopsin (bR), which is a model for structure-function studies of membrane proteins. The heterologous expression of integral membrane proteins (IMPS) is difficult. In this study, we reported the heterologous overexpression of bacterio-opsin (bO) in Escherichia coli BL21 (DE3).
