Streptomyces lividans is a Gram-positive bacterium known for its remarkable secretion efficiency and low extracellular protease activity. In the present work, we adapted the highly productive T7 expression system to S. lividans. A codon-optimized T7 RNA polymerase gene was chromosomally integrated, and a bifunctional T7 expression vector was constructed.

Post-translational modification (PTM) has a significant impact on cellular signaling and function regulation. In pancreatic β cells, PTMs are involved in insulin secretion, cell development, viability. The dysregulation of PTM cells is clinically associated with the development diabetes mellitus. Here, we summarized current findings major occurring their roles secretion. Our work provides compr...

expression of eukaryotic proteins in e. coli often results in their aggregation. proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. this is not achieved in cytoplasmic expression in e. coli because of the absence of disulfide bonds formation. a novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...

OBJECTIVE The (CTG)(n) polymorphism in the serum carnosinase (CN-1) gene affects CN-1 secretion. Since CN-1 is heavily glycosylated and glycosylation might influence protein secretion as well, we tested the role of N-glycosylation for CN-1 secretion and enzyme activity. We also tested whether CN-1 secretion is changed under hyperglycemic conditions. RESULTS N-glycosylation of CN-1 was either ...

Background: Pancreatic islet transplantation is one of the most promising strategies for treating patients with type I diabetes mellitus.Objective: We aimed to assess the immunoisolation properties of the multilayer encapsulated islets using alginate-chitosan-PEG for immunoprotection and insulin secretion from the encapsulated islets induced under differe...

it is well established that the esophageal distention (ed) leads to gastric relaxation, partly by vago-vagal reflex, but till now, the effect of ed on gastric acid secretion has not been investigated. the aim of this study was to investigate the effect of ed on basal and stimulated gastric acid secretion. methods: adult male wistar rats (200-240 g) were deprived of food but not the water 24 h b...

During the last few years, the use of type III secretion system-based bacterial vectors for immunotherapy purposes has been assessed in various applications. We showed that a type III secretion-based Pseudomonas aeruginosa vector delivering the ovalbumin (OVA) antigen induced an efficient specific CD8+ T-lymphocyte immune response against OVA-expressing cells. Because of the intrinsic toxicity ...
