BACKGROUND: Forkhead box P3 (Foxp3) is the most reliable marker for regulatory T cells, which play an important role in maintaining renal allograft tolerance. Recently, Foxp3 polymorphisms have been reported to be associated with graft outcome in kidney transplantation. We analyzed the association of Foxp3 polymorphisms with renal allograft outcome. METHODS: Foxp3 polymorphisms (rs3761548 A/C, rs2280883 C/T, rs5902434 del/ATT, and rs2232365 A/G) were tested by PCR with sequence-specific primers (PCR-SSP) in 231 adult kidney transplantation recipients from 1996-2004 at Seoul National University Hospital...

REVIEW
Paolo Baldi, Nicola La Porta
In the never ending struggle against plant pathogenic bacteria, a major goal is the early identification and classification of infecting microorganisms. Xylella fastidiosa, a Gram-negative bacterium belonging to the family Xanthmonadaceae, is no exception as this pathogen showed a broad range of vectors and host plants, many of which may carry the pathogen for a long time without showing any symptom. Till the last years, most of the diseases caused by X. fastidiosa have been reported from North and South America, but recently a widespread infection of olive quick decline syndrome caused by this fastidious pathogen appeared in Apulia (south-eastern Italy), and several cases of X...

Genome integrity relies on the ability of the replisome to navigate ubiquitous DNA damage during DNA replication. The Escherichia coli replisome transiently stalls at leading-strand template lesions and can either reinitiate replication downstream of the lesion or recruit specialized DNA polymerases that can bypass the lesion via translesion synthesis. Previous results had suggested that the E. coli replicase might play a role in lesion bypass, but this possibility has not been tested in reconstituted DNA replication systems...

Accurate diagnosis of malaria infections continues to be challenging and elusive, especially in the detection of submicroscopic infections. Developing new malaria diagnostic tools that are sensitive enough to detect low-level infections, user friendly, cost effective and capable of performing large scale diagnosis, remains critical. We have designed novel self-quenching photo-induced electron transfer (PET) fluorogenic primers for the detection of P. ovale by real-time PCR. In our study, a total of 173 clinical samples, consisting of different malaria species, were utilized to test this novel PET-PCR primer...

Brucellosis is one of the leading causes of abortion in domestic animals that imposes costs on both economy and society. The disease is highly zoonotic and poses risk to animal handlers due to its zoonotic nature. It causes stillbirth, loss of kids and abortion in last term of pregnancy. Reproductive damage includes infertility in does and orchitis and epididymitis in breeding bucks, which result in high financial losses to farmers and the agriculture industry as a whole. It requires highly sensitive and specific assays to diagnose the disease at field level...

The melanoma-associated antigen (MAGE) genes are known to be expressed in various kinds of tumors including lung cancer. Although they are studied as targets for immunotherapy and tools for early detection of lung cancer, the correlation between MAGE expression and the prognosis in lung cancer has not been clarified. In this study, we evaluated the relationship between MAGE A1-6 gene expression and the clinical prognosis in lung cancer. Bone marrow aspirations were performed in 60 patients who were diagnosed as lung cancer and underwent lung cancer surgery between 2007 and 2008...

BACKGROUND: Within the Brassicaceae, six species from the genus Brassica are widely cultivated throughout the world as oilseed, condiment, fodder or vegetable crops. The genetic relationships among the six Brassica species are described by U's triangle model. Extensive shared traits and diverse morphotypes among Brassica species make identification and classification based on phenotypic data alone challenging and unreliable, especially when dealing with large germplasm collections. Consequently, a major issue for genebank collections is ensuring the correct identification of species...

The species Erysipelothrix rhusiopathiae displays genetic heterogeneity; however, E. rhusiopathiae serovar 1a strains currently circulating in Japan exhibit remarkably low levels of genetic diversity and group into clonal sublineages of Lineage IVb (IVb-1 and IVb-2). In the present study, based on whole genome sequencing data, we designed primers for a multiplex PCR assay to simultaneously detect and differentiate the sublineages of E. rhusiopathiae strains. Among the one hundred and twenty-seven isolates of various serovar strains, including isolates from a wide range of hosts and geographic origins, the PCR assay could successfully detect and differentiate the serovar 1a strains belonging to the sublineages...

The nuclear ribosomal DNA (rDNA) is considered as a paradigm of concerted evolution. Components of the rDNA tandem repeats (45S) are widely used in phylogenetic studies of different organisms and the internal transcribed spacer (ITS) region is recently selected as a fungal DNA barcode. However, rRNA pseudogenes, as one kind of escape of concerted evolution, were reported in a wide range of organisms, especially in plants and animals. Moreover, large numbers of 5S rRNA pseudogenes were identified in several filamentous ascomycetes...

The hepatitis B virus (HBV) covalently closed circular (CCC) DNA functions as the only viral template capable of coding for all the viral RNA species and is thus essential to initiate and sustain viral replication. CCC DNA is converted, in a multi-step and ill-understood process, from a relaxed circular (RC) DNA, in which neither of the two DNA strands is covalently closed. To detect putative intermediates during RC to CCC DNA conversion, two 3' exonucleases Exo I and Exo III, in combination were used to degrade all DNA strands with a free 3' end, which would nevertheless preserve closed circular DNA, either single-stranded (SS) or double-stranded (DS)...

Ortleppascaris sinensis (Nematoda: Ascaridida) is a dominant intestinal nematode of the captive Chinese alligator. However, the epidemiology, molecular ecology and population genetics of this parasite remain largely unexplored. In this study, the complete mitochondrial (mt) genome sequence of O. sinensis was first determined using a polymerase chain reaction (PCR)-based primer-walking strategy, and this is also the first sequencing of the complete mitochondrial genome of a member of the genus Ortleppascaris...

Oncoimmunology (or immunooncology) is a burgeoning specialty of precision ("personalized") medicine designed to heighten the antitumor response of the immune system against molecules expressed excessively or only by tumor cells. This focus is necessary, as cancers are polyclonal tissues comprised of antigenically heterogeneous cells, the exact composition of which is shaped by the balance between antitumor immunity and tumor-promoting inflammation. Key targets include enhancing immune system (especially T cell) reactivity, inhibiting immune checkpoints, and promoting tumor cytolysis...

β-Thalassemia (β-thal) is the most prevalent hereditary blood disorder in Pakistan with a carrier rate of 5.0-8.0%. The homozygous affected children require frequent blood transfusions for their survival. This autosomal recessive disease can only be prevented through awareness programs, carrier screening, mutation detection, genetic counseling and prenatal diagnosis (PND). The present study aimed to determine the prevalence of various mutations causing β-thal and also to detect carriers of these mutations in families living in the Mardan Division, Khyber Pakhtunkhwa (KP) Province, Pakistan...

Dong-Xiu Xue, Yu-Long Li, Jin-Xian Liu
As one of the most informative and versatile DNA-based markers, microsatellites have been widely used in population and conservation genetic studies. However, the development of microsatellites has traditionally been laborious, time-consuming, and expensive. In the present study, a rapid and cost-effective "RAD-seq-Assembly-Microsatellite" approach was developed to identify abundant microsatellite markers in non-model species using the roughskin sculpin Trachidermus fasciatus as a representative. Overlapping paired-end Illumina reads generated by restriction-site-associated DNA sequencing (RAD-seq) were clustered based on the similarity of reads containing the restriction enzyme recognition site and then assembled into contigs, which were used for microsatellite discovery and primer design...

Two species of Burkholderia pseudomallei complex (Bpc), B. pseudomallei and B. mallei, can cause severe life-threatening infections. Rapidly discerning individual species within the group and separating them from other opportunistic pathogens of the Burkholderia cepacia complex (Bcc) is essential to establish a correct diagnosis and for epidemiological surveillance. In this study, a multiplex PCR assay based on the detection of an individual set of chromosomal beta-lactamase genes for single-step identification and differentiation of B...
