the present study was to construct a parentage verification system for iranian caspian horse. a total number of 45 caspian horse samples including 14 foals for parentage verification, 17 stallion and 14 mare for individual identification were genotyped. genomic dna was extracted from whole blood and the genotype were analysed by pcr procedure and using 7 microsatellite markers (aht04, hms03, hm...

results this study shows the prepared gene construct is inducible by glucose. gene expression of preproinsulin was observed in muscle tissue of rabbits. conclusions these finding indicated that research in diabetes mellitus gene therapy could be performed on larger animals. objectives the purpose of this study was to construct glucose inducible insulin gene plasmid and use it in the muscle tiss...

We have developed a method for transferring exogenous DNA molecules into isolated mammalian mitochondria using bacterial conjugation. In general, we accomplish this by (i) inserting an origin of DNA transfer (oriT) sequence into a DNA construct, (ii) transforming the construct into an appropriate Escherichia coli strain and then (iii) introducing the mobilizable DNA into mitochondria through co...

Gene expression is under the influence of DNA methylation and assembly of chromatin structure. This paper reports the modulation of transgene expression in zebrafish embryos by altering DNA methylation with 5-azacytidine and heterochromatin formation with sodium butyrate, an inhibitor of histone deacetylation. A CMV promoter-luciferase fusion gene construct (pCMVL) microinjected into zebrafish ...

Approximately 6000 specific DNA deletion events occur during development of the somatic macro-nucleus of the ciliate Tetrahymena. The eliminated Tlr1 element is 13 kb or more in length and has an 825 bp inverted repeat near the rearrangement junctions. A functional analysis of the cis -acting sequences required for Tlr1 rearrangement was performed. A construct consisting of the entire inverted ...

There are many techniques to knock out directed genes in bacteria, some of which have been described in Salmonella species. In this study, a combination of SOEing PCR method and the λ Red disruption system were used to disrupt phoP gene in wild type and standard strains of Salmonella typhimurium. Three standards PCR and one fusion PCR reactions were performed to construct a linear DNA including...

Several lines of evidence demonstrate that the DNA of the iridovirus frog virus 3 (FV3) is methylated in all 5'-CG-3' sequences both in virion DNA and in the intracellular viral DNA at late times after infection. The 5-methyldeoxycytidine residues in this viral DNA occur exclusively in 5'-CG-3' dinucleotide positions. We have cloned and determined the nucleotide sequence of the L1140 gene and i...

Several lines of evidence demonstrate that the DNA of the iridovirus frog virus 3 (FV3) is methylated in all 5*-CG-3* sequences both in virion DNA and in the intracellular viral DNA at late times after infection. The 5-methyldeoxycytidine residues in this viral DNA occur exclusively in 5*-CG-3* dinucleotide positions. We have cloned and determined the nucleotide sequence of the L1140 gene and i...

Background: Sugarcane is a monocotyledonous crop that is cultivated in the tropical and subtropical regions of the world. One of the most important criteria, influencing the efficiency of the sugarcane transformation is known to be related to physical and biological factors during the transformation procedure. Objectives: The objective of this research was to study the response of callus induc...

The exploitation of DNA for the production of nanoscale architectures presents a young yet paradigm breaking approach, which addresses many of the barriers to the self-assembly of small molecules into highly-ordered nanostructures via construct addressability. There are two major methods to construct DNA nanostructures, and in the current review we will discuss the principles and some examples ...
