Background Environmental and cellular inappropriate conditions can cause damages to cells nucleotide poll. Deamination and oxidation damages interfere with cell�s vital reactions. Inosine triphosphate pyrophosphatase (ITPA), an evolutionary conserved enzyme, plays a critical role in elimination of non-canonical bases. In human genome, the ITPA gene is located on chromosome 20 short arm and tran...
background: over the past several years, mammals have been successfully cloned by either the splitting of an early stage embryo or nuclear transfer of adult somatic cells (nt) into oocytes. although it has been 15 years since the generation of the first cloned mammals from somatic cells by nt, the success rate for producing live offspring by this technique is low regardless of the cell type and...
Genetic typing methods of T. gondii strains have been extensively perfected in recent years. From a technical point of view, many tools usable for genetic studied on single-copy loci have been used: RFLP, PCR-RFLP, sequencing, RAPD-PCR and isoenzyme analysis. We described the cloning and sequence analysis of the gene which encodes the major surface antigen (SAG1 or P30) of T. gondii. SAG1 is ...
Leishmanolysin is a worldwide disease that is caused by different species of the genus Leishmania. Leishmanolysin, One of the genes expressed by Leishmania, appears to be an ideal candidate for genetic vaccination. In this study, a full length sequence, which encodes Leishmanolysin functionally critical regions (amino acids 100-579), was cloned from a Leishmania strain endemic to Iran. Analysis...
Whereas it has been assumed that genetically modified tissues or cells derived from somatic cell nuclear transfer (SCNT) should be accepted by a host of the same species, their immune compatibility has not been extensively explored. To identify acceptance of SCNT-derived cells or tissues, skin grafts were performed between cloned dogs that were identical except for their mitochondrial DNA (mtDN...
