Background and purpose: Clostridium botulinum bacteria produces seven types of botulinum neurotoxins among which types A, B, E and F are responsible for human botulism. One of the treatments for botulism is the inhibition of botulinum neurotoxins catalytic domain activity by inhibitors. In this study, botulinum neurotoxin type E catalytic domain has been cloned in pET28a vector and expressed in...
Introduction: Inteins (INT) are internal parts of a number of proteins in yeast and some other unicellular eukaryotes, which can be separated from the immature protein during protein splicing process. After identifying the mechanism of intein action, applications of these sequences are be considered in the single- step purification of recombinant proteins and different intein tags were develope...
We studied the effect of loss of function in the NIP subfamily II in Arabidopsis thaliana to assess their potential role(s) in arsenite (AsIII) uptake. Loss of function in AtNIP7;1 led to increased plant tolerance to AsIII and reduced total As in planta. AtNIP7;1 expression in various yeast backgrounds increased AsIII sensitivity. In the acr3Delta yeast genotype, AtNIP7;1 caused a moderate incr...
A single-stranded DNA (ssDNA)-binding protein (SSB) that binds to specific upstream sequences of alcohol oxidase (AOX1) promoter of the methylotrophic yeast Pichia pastoris has been isolated and identified as zeta crystallin (ZTA1). The cDNA encoding P.pastoris ZTA1 (PpZTA1) was cloned into an Escherichia coli expression vector, the recombinant PpZTA1 was expressed and purified from E.coli cell...
Background and purpose: MicroRNA regulation of cancer-related pathways has a major effect on cancer development. MiR-429 is a member of miR-200 family with an important role in metastasis. There are many studies on the association between miR-429 and liver, bladder, bowel, and gastric cancers. In this study, we investigated the expression changes of E2F3 genes after transfection of MCF-7 cells ...
Development of yeast artificial chromosome (Y AC) vectors, molecular cloning of large segments of chromosomal DNA, and their propagation in yeast cells has become feasible. Overlapping Y AC provides a route to the development of physical maps of entire mammalian chromosomes. A rapid method was developed to isolate and sequence termini of Y AC inserts quickly. The Y AC clone is digested wit...
we can reach by dna microarray gene expression to such wealth of information with thousands of variables (genes). analysis of this information can show genetic reasons of disease and tumor differences. in this study we try to reduce high-dimensional data by statistical method to select valuable genes with high impact as biomarkers and then classify ovarian tumor based on gene expression data of...
background and objectives: baculovirus can be used as a vector in gene delivery system. viral envelope of baculovirus would display expressed protein/peptide and it could render as a potential vaccine delivery system. in this regard, the gene coding for a subunit of shiga toxin (stxa) from escherichia coli ( e. coli ) strain was cloned in a baculovirus expression system. stxa subunit has the ab...
