Background & Aims: Breast cancer is the most common cancer in women. Nearly 50% of breast cancers are dependent to sex hormones, and the effects of these hormones are mediated by their binding to specific receptors. Also p53 protein is mutated in about half of cancers including breast cancer and high level of p53 protein is a common feature of many human malignant cancers. Given that T47D cell...
In this study, our previously reported novel synthetic gene encoding 166 residues of interferon-? was used for an efficient expression of IFN-?. The synthetic gene was cloned into pET21a expression vector and transferred into E. coli. Recombinant protein was over-expressed in the E. coli. Identity of the recombinant protein was confirmed by western blot analysis. The recombinant protein was bio...
Background: The molecular studies indicate some of the genes in the promoter region itself, will undergo methylation. Methylation of CpG islands in the promoter region of that cause silence or reduced expression of genes involved in cell growth pathways, which are colorectal cancer causing agents. Detection of methylation status can be used as a marker for cancer diagnosis and prediction of dis...
RNA interference is an evolutionarily conserved double-stranded RNA-triggered mechanism for suppressing gene expression. Rotaviruses, the leading cause of severe diarrhea in young children, are formed by three concentric layers of protein, from which the spike protein VP4 projects. Here, we show that a small interfering RNA corresponding to the VP4 gene efficiently inhibits the synthesis of thi...
Infectious bronchitis (IB) is an acute and contagious disease of poultry. The spike glycoprotein (S) of IB virus is a dimmer and is cleaved into two glycopolypeptides, S1 and S2 post-translationally. S1 gene defines the serotype and plays a major role in induction of protective immunity. Eukaryotic expression systems are frequently employed for the production of recombinant S1 proteins as it is...
A 13-year-old girl with generalized tonic and grand mal seizures had brain MRI that revealed subcortical band heterotopia (SBH) (figure 1). Twenty-fourhour EEG showed pervasive generalized slow spike and wave pattern (figure 2). Blood DNA confirmed a mutation in the doublecortin (DCX) gene. Interictal 18-fluoro-deoxy (FDG) PET showed reduced FDG uptake ( 10%) in the cerebral cortex and intensel...
background: the hbv-x (hbx) protein is believed to contribute to the development of hcc. however, the molecular mechanisms involved in hbx-mediated hepatocarcinogenesis remain obscure. in this study, the effect of hepatitis b virus x gene and its protein product hbxag on expression of p53 gene in hep g2 cell line was investigated. methods: viral dna extracted from hbv-positive serum and hbx gen...
Abstract Backgraound: Entamoeba histolytica antigenic markers such as Serine-Rich E. histolytica protein (SREHP) have recently been used for vaccine preparation, genetic diversity studies of Entamoeba histolytica isolates and for differentiation between E. histolytica and E. dispar species. This study was carried out with the aim of expression of a recombinant Serine Rich E. histolytica prot...
N-terminal Domain of SARS-CoV-2 Spike Protein In article number 2100152, Yao Li, Tong Wang, Haipeng Gong, and co-workers propose the “wedge” model to demonstrate regulatory function domain (NTD) protein. The NTD typically wedges in prohibit receptor binding domain's (RBD's) movements it occasionally moves out allow RBD tilt downward.
infectious bursal disease virus (ibdv) is the causative agent of gumboro disease, an infectious disease of global economic importance in poultry. structural protein vp2 of ibdv is the most frequently studied protein due to its significant roles in virus attachment, protective immunity, and serotype specificity. the objective of the present study was to improve the expression of hypervariable re...
