The purpose of this study was to develop a novel approach without control population to examine the relationship between the presence of specific allele combinations at different loci with the onset of gastric cancer.DNA samples were collected from patients with gastric cancer. Alleles from short tandem repeat loci were determined using the STR Profiler Plus PCR amplification kit (15 STR loci). The...
This review summarizes the contribution of matrix metalloproteinases to the pathogenesis of psoriasis. In psoriasis, matrix metalloproteinases are involved in the structural changes of the epidermis via the modification of intracellular contacts and the composition of the extracellular matrix, promoting angiogenesis in the dermal blood vessels and the infiltration of immune cells. Moreover, some matrix...
α-Tocopherol transfer protein (α-TTP) is a cytosolic protein that plays an important role in regulating concentrations of plasma α-tocopherol (the most bio-active form of vitamin E). Despite the central roles that α-TTP plays in maintaining vitamin E adequacy, we have only recently proved the existence of the α-TTP gene in sheep and, for the first time, cloned its full-length cDNA. However, the study...
Five primer sets were designed in order to identify single nucleotide polymorphisms (SNPs) in middle and terminal exons (2 to 6) and in some flanking intronic regions of the bovine insulin-like growth factor 1 (IGF-1) gene. Sequencing results of PCR products for 10% of animals showed no variant in exons but a SNP at intron 4 was occurred. Both polymerase chain reaction–restriction fragment length...
A genome triplication took place in the ancestor of Brassiceae species after the split of the Arabidopsis lineage. The postfragmentation and shuffling of the genome turned the ancestral hexaploid back to diploids and caused the radiation of Brassiceae species. The course of speciation was accompanied by the loss of duplicate genes and also influenced the evolution of retained genes. Of all the genes,...
The present study made attempts to update comprehensive eutherian Mas-related G protein-coupled receptor gene data sets, using public eutherian genomic sequence data sets and new genomics and molecular evolution tests. Among 254 potential coding sequences, the most comprehensive gene data set of eutherian Mas-related G protein-coupled receptor genes included 119 complete coding sequences that described...
Intron-targeting (IT) markers were developed from next generation sequencing (NGS) derived transcript sequencing data from the potato cultivar White Lady. The applicability of the IT markers was analyzed in other potato genotypes, and their transferability was studied in other Solanum species: section Archaesolanum (5 species), sect. Solanum (6 species) and a Solanum nigrum population (11 genotypes)...
The objective of this study was to investigate gene transcription profiles of the stage IV ovary and the ovotestis of the rice field eel (Monopterus albus) in an attempt to uncover genes involved in sex reversal and gonad development. Suppression subtractive hybridization (SSH) libraries were constructed using mRNA from the stage IV ovary and the ovotestis. In total 100 positive clones from the libraries...
The neural crest (NC) is a transient dynamic structure of ectodermal origin, found in early vertebrate embryos. The multipotential NC cells migrate along well defined routes, differentiate to various cell types including melanocytes and participate in the formation of various permanent tissues. As there is only limited information about the molecular mechanisms controlling early events in melanocyte...
The Rab family, the largest branch of Ras small GTPases, plays a crucial role in the vesicular transport in plants. The members of Rab family act as molecular switches that regulate the fusion of vesicles with target membranes through conformational changes. However, little is known about the Rab5 gene involved in fruit ripening and stress response. In this study, the MiRab5 gene was isolated from...
In crustaceans, the androgenic gland (AG), thanks to the synthesis of the androgenic gland hormone (AGH), controls the differentiation of the primary and secondary male sexual characters. In this study, we amplified 12 new AGH cDNAs in species belonging to five different families of the infra-order Ligiamorpha of terrestrial isopods. Putative essential amino acids for the production of a functional...
Rosa chinensis ‘Pallida’ (Rosa L.) is one of the most important ancient rose cultivars originating from China. It contributed the ‘tea scent’ trait to modern roses. However, little information is available on the gene regulatory networks involved in scent biosynthesis and metabolism in Rosa. In this study, the transcriptome of R. chinensis ‘Pallida’ petals at different developmental stages, from flower...
The proteins encoded by psaA and psaB form a heterodimer, an essential compound of photosystem; while the protein encoded by psbC binds with chlorophyll a in photosystem II, serving as antennae in photosystem. Here we report that a heterocyclic brominated flame retardant, tris(2,3-dibromopropyl) isocyanurate (TBC), inhibited the expression of psaA and psbC, then leads to the decrease of Nannochloropsis...
There is considerable debate about the most efficient way to interrogate rare coding variants in association studies. The options include direct genotyping of specific known coding variants in genes or, alternatively, sequencing across the entire exome to capture known as well as novel variants. Each strategy has advantages and disadvantages, but the availability of cost-efficient exome arrays has...
Mollusks have received increasing interest in ecotoxicological studies but so far the available scientific analyses of how their genes are affected by anthropogenic pollutants are scarce. The focus of this study is to identify an estrogen receptor (er) gene in the common prosobranch snail Bithynia tentaculata and to test a hypothesis that 17α-Ethinylestradiol (EE2) will modulate er gene expression...
Candida bombicola is well-studied for the production of a biosurfactant, the sophorolipids. In this paper, the cloning of a glucosyltransferase gene using polymerase-chain-reaction (PCR) technique is described. Degenerative primer-pairs were first designed based on the highly conserved amino-acid sequences of several selected yeast glucosyltransferases. Using these primers, an amplified sequence (amplicon)...
Rem2 is a member of the RGK (Rem, Rad, and Gem/Kir) subfamily of the Ras superfamily of GTP binding proteins. In mammals, Rem2 has been found to be unique in not only its structure, but also its tissue specificity, as it is the first member to be found at high levels in neuronal tissue. Because Rem2 has previously been implicated in neuronal cell proliferation, and amphibians maintain relatively high...
Species of the genus Mytilus carry two mitochondrial genomes in obligatory coexistence; one transmitted though the eggs (the F type) and one through the sperm (the M type). We have studied the 3′ and 5′ ends of rRNA and tRNA transcripts using RT-PCR and RNA circularization techniques in both the F and M genomes of Mytilus galloprovincialis. We have found polyadenylated and non-adenylated transcripts...
