امروزه سرطان دهانه ی رحم به عنوان دومین عامل مرگ و میر بر اثر سرطان در میان زنان، به عنوان یکی از معضلات بهداشتی به ویژه، در کشورهای در حال توسعه به حساب می آید. مشخص شده است که سرطان دهانه ی رحم ارتباط زیادی با عفونت های ویروس پاپیلومای انسانی دارد. انکوژن های ویروسی e7 و e6، دائماً به وسیله ی سلول های توموری بیان می شوند، به همین دلیل، اهداف ایمنی زایی مناسبی جهت استفاده در واکسن های درمانی ژن...
The Polarization Effect and Mechanism of China’s Green Finance Policy on Green Technology Innovation
The advancement of green technology innovation (GTI) is crucial for facilitating development. China, the largest carbon-emitting economy, should prioritize acceleration GTI to augment global economic growth and reduce carbon emissions. Green finance policy (GFP) a common instrument encouraging enterprises develop GTI. This study, therefore, takes pilot China’s Finance Reform Innovation Pilot Zo...
Proglucagon, which is encoded by the glucagon gene (Gcg), is the precursor of several peptide hormones, including glucagon and glucagon-like peptide 1 (GLP-1). Whereas glucagon stimulates hepatic glycogenolysis and gluconeogenesis, GLP-1 stimulates insulin secretion to lower blood glucose and also supports ß-cell proliferation and protection from apoptotic stimuli. Pregnancy is a strong inducer...
Green fluorescent protein (GFP) is a 27 kD protein consisting of 238 amino acid residues [1]. GFP was first identified in the aquatic jellyfish Aequorea victoria by Osamu Shimomura et al. in 1961 while studying aequorin, a Ca2+-activated photoprotein.Aequorin and GFP are local‐ ized in the light organs of A. victoria and GFP was accidentally discovered when the energy of the blue light emitted ...
Gastric inhibitory polypeptide (GIP) exhibits potent insulinotropic effects on β-cells and anabolic effects on bone formation and fat accumulation. We explored the impact of reduced GIP levels in vivo on glucose homeostasis, bone formation, and fat accumulation in a novel GIP-GFP knock-in (KI) mouse. We generated GIP-GFP KI mice with a truncated prepro-GIP gene. The phenotype was assessed in he...
Recently, misuse or overuse of antibiotics has led to the antibiotic resistance problem, a global healthcare problem. Most virulence factors and biofilm formation in Pseudomonas aeruginosa are controlled by quorum sensing (QS). The inhibition QS system inhibitor molecules been suggested as novel alternative antivirulence approach which no need kill bacteria. In present study, inhibitory potenti...
Background & Objective: In order to enhance the expression of soluble proteins and facilitate their purification and development of multi-functional polypeptide , chimerical recombinant proteins have been invented . The purpose of this study was to construct ctxB-gfp-stxB gene cassette to measure the uptake and excretion of chimerical antigen in future studies. Materials & Methods: After prep...
Background: Escherichia coli is still the common host for ing and heterologous protein expression. Various strategies have been employed to increase protein expression in E. coli, but, it seems that external factors such as selection marker concentration can drastically aff ect the yield of protein and plasmid.Objectives: Alterations of protein expression...
Defects in glucagon action can cause hyperplasia of islet α-cells, however, the underlying mechanisms remain largely to be elucidated. Mice homozygous for a glucagon-GFP knock-in allele (Gcg(gfp/gfp) ) completely lack proglucagon-derived peptides and exhibit hyperplasia of GFP-positive α-like cells. Expression of the transcription factor, aristaless-related homeobox (ARX), is also increased in ...
