Whether present-day European genetic variation and its distribution patterns can be attributed primarily to the initial peopling of Europe by anatomically modern humans during the Paleolithic, or to latter Near Eastern Neolithic input is still the subject of debate. Southeastern Europe has been a crossroads for several cultures since Paleolithic times and the Balkans, specifically, would have been...
To determine if ethanol consumption and alcoholism cause global DNA methylation disturbances, we examined alcoholics and controls using methylation specific microarrays to detect all annotated gene and non-coding microRNA promoters and their CpG islands. DNA was isolated and immunoprecipitated from the frontal cortex of 10 alcoholics and 10 age and gender-matched controls then labeled prior to co-hybridization...
The Guinea pig (Cavia porcellus) is one of the most relevant small animals for modeling human tuberculosis (TB) in terms of susceptibility to low dose aerosol infection, the organization of granulomas, extrapulmonary dissemination and vaccine-induced protection. It is also considered to be a gold standard for a number of other infectious and non-infectious diseases; however, this animal model has...
Large numbers of microRNAs (miRNAs) reportedly play important roles in plant development. However, none has been reported in Pinellia pedatisecta, an important aroid medicinal plant that possesses the only pedate leaf blades and the largest tubers and inflorescences among all Pinellia species. To detect the miRNAs from P. pedatisecta, an in situ synthesized custom miRNA microarray was employed, following...
Cyclin-dependent kinase 10 (Cdk10) is a Cdc2-related kinase and plays an essential role in the progression from the G2 to M phase of the cell cycle. However, relative little is known about its expression pattern, clinical relevance, and biological function in hepatocellular carcinoma (HCC). In the present study, we investigated the mRNA and protein expression levels of Cdk10 in 127 pairs of HCC samples...
Hypoxia-inducible factors (HIFs) are transcription factors that respond to changes in oxygen tension in the cellular environment. In this study, we identified full-length cDNAs of HIF-1α, HIF-2α and HIF-3α in an endangered hypoxia-sensitive fish species, Chinese sucker. The HIF-1α/2α/3α cDNAs are 3890, 3230 and 3374bp in length, encoding 780, 782 and 632 amino acid residues, respectively. The real-time...
Production of marker-free genetically modified (GM) plants is one of the major challenges of molecular fruit breeding. Employing clean vector technologies, allowing the removal of undesired DNA sequences from GM plants, this goal can be achieved. The present study describes the establishment of a clean vector system in apple Malus×domestica Borkh., which is based on the use of the neomycin phosphotransferase...
The existence of fractal sets of DNA sequences have long been suspected on the basis of statistical analyses of genome data. In this article we identify for the first time explicitly the GA-sequences as a class of fractal genomic sequences that are easy to recognize and to extract, and are scattered densely throughout the chromosomes of a large number of genomes from different species and kingdoms...
Small supernumerary marker chromosomes (sSMCs) are a heterogeneous group with regards to their clinical effects as well as their chromosomal origin and their shape. The sSMCs are associated with mental retardation and dysmorphic features. Multiple sSMCs are rarely reported. We report four sSMCs in a case of dysmorphic features and intellectual disabilities. Among the four sSMCs, one sSMC confirmed...
Xenobiotic transport proteins are involved in cellular defence against accumulation of xenobiotics participating in multixenobiotic resistance (MXR). In order to study the transcriptional regulation of MXR genes in fish exposed to common chemical pollutants we selected the thicklip grey mullet (Chelon labrosus), since mugilids are widespread in highly degraded estuarine environments where they have...
X-linked adrenoleukodystrophy (ALD; MIM #300100) is a neurodegenerative disorder caused by mutations in the ABCD1 adrenoleukodystrophy protein gene. The ABCD1 gene mutations have been reported by laboratories in China and Japan, but not in Korea. This case report describes a Korean boy diagnosed with X-ALD. Direct sequencing for the ABCD1 gene in this boy and his mother detected Tyr620His missense...
Familial hypercholesterolemia (FH) is an autosomal dominant disease caused by mutations in low-density lipoprotein receptor (LDLR), apolipoprotein B-100 (APOB), and proprotein convertase subtilisin/kexin type 9 (PCSK9) genes. This study investigated FH patients carrying common mutations in Taiwan and compared them to FH southeastern Asians. Causal FH mutations were identified by exon-by-exon sequencing...
The paraoxonase (PON1) gene polymorphisms are known to affect the PON1 activity and coronary artery disease (CAD) risk. Studies done so far have given conflicting results. In the present study, we determined the role of PON1 genetic variants and PON1 activity in the development of CAD in North–West Indian Punjabis, a distinct ethnic group, having high incidence of both CAD and type 2 diabetes. 300...
Fibroblast Growth Factors (FGFs) regulate prenatal and postnatal bone formation through activation of FGF receptors (FGFR) and downstream signaling events. During the last decade, major advances have been made in our understanding of the mechanisms by which FGF/FGFR signaling controls osteoprogenitor cell replication and osteoblast differentiation and function. The analysis of the phenotype induced...
Thyroid peroxidase (TPO) gene variations are one cause of thyroid autoimmune diseases. The aim of this study was to examine the association between the T1936C, T2229C and A2257C polymorphisms of the TPO gene and Anti-TPO level.In this case–control study, 188 individuals (86 males and 102 females), aged 20–80years, were randomly selected from among the Tehran Lipid and Glucose Study (TLGS) population...
Experimental evidence suggests that heat shock proteins (HSP) and asymmetric dimethylarginine (ADMA) are induced in the state of chronic inflammation and stress conditions. They are both inhibitors of nitric oxide synthase (NOS). The aim of this study was to evaluate the correlation between ADMA and HSP70, in patients with type 2 diabetes with respect to serum levels of C reactive protein (CRP).We...
Genome-wide methylation studies frequently lack adequate controls to estimate proportions of background reads in the resulting datasets. To generate appropriate control pools, we developed technique termed nMETR (non-methylated tag recovery) based on digestion of genomic DNA with methylation-sensitive restriction enzyme, ligation of adapter oligonucleotide and PCR amplification of non-methylated sites...
3-Hydroxy-3-methylglutaryl coenzyme A reductase (HMGR, EC: 1.1.1.34), an enzyme catalyzing the first committed step in the mevalonic acid (MVA) pathway for the biosynthesis of isoprenoids, has been reported to be involved in the fruit size determination through the regulation of early cell division. In litchi, the cell number achieved by this early cell division determines the final fruit size, but...
Lymphoedema–distichiasis syndrome (LDS, OMIM #153400) is a genetic disorder with an autosomal dominant pattern of inheritance caused by mutations in the FOXC2 gene. Affected individuals typically present with lower extremity lymphoedema and distichiasis. The most common types of mutations in FOXC2 gene include small deletions and insertions, but duplications, duplications-insertions, missense and...
