BACKGROUND The main goal of present study was to detect polymorphism in MSP-1 gene which is a major blood stage candidate for vaccine in Plasmodium vivax by Single Strand Conformational Polymorphism-Polymerase Chain Reaction (SSCP-PCR). METHODS During 2008 to 2010 fifty samples were collected from Iranian patients with P. vivax in Hormozgan Province, southern Iran. All of the samples were det...

A glycoprotein (Cpgp40/15)-encoding gene of Cryptosporidium parvum was analyzed to reveal intraspecies polymorphism within C. parvum isolates. Forty-one isolates were collected from different geographical origins (Japan, Italy, and Nepal) and hosts (humans, calves, and a goat). These isolates were characterized by means of DNA sequencing, PCR-restriction fragment length polymorphism (PCR-RFLP),...

SSCP (single-strand conformational polymorphism) is used widely in the field of human biomedicine, but its potential as a population genetics tool for the recovery of nuclear gene genealogies remains to be realized. We describe and illustrate a use for SSCP in the physical isolation of nuclear haplotypes that circumvents several difficulties associated with more conventional cloning procedures....

The tissue-specific Wilms' tumor gene WT1 is expressed in a range of acute leukemias and hematopoietic cell lines. Using single-strand conformational polymorphism analysis, we have found mutations in the WT1 gene in 4 of 36 acute leukemias. WT1 mutations are found in 15% of cases of acute myeloid leukemia, in which they are associated with a poor response to chemotherapy. The mutations comprise...

It has been reported that selenocysteine tRNA from bovine liver is completely edited to two isoacceptor species, called tRNA([Ser]SecNCA) and tRNA([Ser]SecCmCa), which differ from the gene sequence. We used direct tRNA sequencing, mobility shift analyses, primer extension, restriction enzyme digestion and single strand conformational polymorphism (SSCP) analyses of products from reverse transcr...

Individual plant growth-promoting rhizobacterial (PGPR) strains (Bacillus thuringiensis B2, Bacillus subtilis B10 and Enterobacter cloacae B16) their combination were used, with or without Pythium oligandrum, against Sclerotinia sclerotiorum. In vitro, all biological control agents (BCAs) reduced successfully hyphal growth of the targeted pathogenic fungus. They displayed antifungal activity by...

The aim of this study was to perform molecular and bioinformatics analysis of IGFBP2 gene promoter in association with some economic traits in indigenous Makuee (MS) and Lori-Bakhtiari (LB) breeds. DNA was extracted from blood samples of 120 MS and 200 LB and a 297 bp fragment from the upstream sequences of studied gene was amplified and genotyped by single-strand conformational polymo...

Breast cancer in families with germ line mutations in the TP53 gene has been described in the medical literature. Mutation screening for susceptibility genes should allow effective prophylactic and preventive measures. Using single-strand conformational polymorphism, we screened for mutations in exons 5, 6, 7 and 8 of gene TP53 in the peripheral blood of 8 young non-affected members (17 to 36 y...

Prions are unprecedented infectious pathogens that cause a group of invariably fatal neurodegenerative disease by an entirely novel mechanism. The conformational change in prion proteins results in a change from a predominantly α-helical protein to a β-sheet form, which causes scrapie in sheep and goat. The present study was carried out to identify polymorphisms of the prion protein gene (PrP) ...

C-mos is a highly conserved intronless gene that has proved useful in the analysis of ancient phylogenetic relationships within vertebrates. We selected the Iberian endemic Schreiber's green lizard (Lacerta schreiberi) that persisted in allopatric refugia since the late Pliocene to investigate the utility of the C-mos nuclear gene for intraspecific phylogeographic studies. Our combination of DN...
