The Polycomb Group Protein SUZ12 regulates histone H3 lysine 9 methylation and HP1α distribution
(2007)Regulation of histone methylation is critical for proper gene expression and chromosome function. Suppressor of Zeste 12 (SUZ12) is a requisite member of the EED/EZH2 histone methyltransferase complexes, and is required ...

A polymorphism in the regulatory region of the CC-chemokine receptor 5 gene influences perinatal transmission of human immunodeficiency virus type 1 to African-American infants
(1999)There are natural mutations in the coding and noncoding regions of the human immunodeficiency virus type (HIV-1) CC-chemokine coreceptor 5 (CCR5) and in the related CCR2 protein (the CCR2-64I mutation). Individuals homozygous ...

Population density and food analysis of Bombina variegata and Rana graeca in mountainous riverine ecosystems of northern Pindos (Greece)
(ResearchGate, 2007-06-20)Abundance and diet of Bombina variegata and Rana graeca were investigated from August 2004to August 2005 in two permanent mountain water bodies (Zesto River and Prioni Nazeti Stream)situated in the National Park of Northern ...

Predicting bird song from space
(2013)Environmentally imposed selection pressures are well known to shape animal signals. Changes in these signals can result in recognition mismatches between individuals living in different habitats, leading to reproductive ...

A preliminary RAPD-PCR analysis of Cimicifuga species and other botanicals used for women's health
(2002)Traditional taxonomic methods of botanical identification that rely primarily on morphological observations cannot be used efficiently when only powdered plant materials are available. Thus, our objectives were to determine ...

Presymptomatic molecular diagnosis of autosomal dominant polycystic kidney disease using PKD1- and PKD2-linked markers in Cypriot families
(1996)Autosomal dominant polycystic kidney disease (ADPKD), is a heterogeneous disorder, primarily characterized by the formation of cysts in the kidneys, and the late development in life of progressive chronic kidney failure. ...

Prevalence of genetic mutations that predispose to thrombophilia in a Greek Cypriot population
(2000)Several hereditary disorders, particularly those affecting the physiological anticoagulation systems, have been well established as risk factors for venous thromboembolism. In the present study, we investigated the prevalence ...

Prevention of preneoplastic mammary lesion development by a novel vitamin D analogue, 1α-hydroxyvitamin D5
(1997)Background: The form of vitamin D (vitamin D3) in fortified milk and the provitamin D produced by the body undergo metabolic activation to a biologically active form, 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3]. This compound ...

Primary resistance to integrase strand-transfer inhibitors in Europe
(2015)Objectives: The objective of this study was to define the natural genotypic variation of the HIV-1 integrase gene across Europe for epidemiological surveillance of integrase strand-transfer inhibitor (InSTI) resistance. ...

Processing of the FMRFamide Precursor Protein in the Snail Lymnaea stagnalis: Characterization and Neuronal Localization of a Novel Peptide, ‘SEEPLY’
(1993)In the pulmonate snail Lymnaea stagnalis, FMRFamide‐like neuropeptides are encoded by a multi‐exon genomic locus which is subject to regulation at the level of mRNA splicing. We aim to understand the post‐translational ...

Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...

Pseudomonas aeruginosa core metabolism exerts a widespread growth-independent control on virulence
(2020)To assess the role of core metabolism genes in bacterial virulence - independently of their effect on growth - we correlated the genome, the transcriptome and the pathogenicity in flies and mice of 30 fully sequenced ...

Quantitation of human immunodeficiency virus type 1 DNA forms with the second template switch in peripheral blood cells predicts disease progression independently of plasma RNA load
(2002)There are several forms of human immunodeficiency virus type 1 (HIV-1) DNA in peripheral blood T cells and lymph nodes in untreated HIV-1-infected individuals and in patients whose plasma HIV-1 RNA levels are suppressed ...

Quantitative analysis of serum neutralization of human immunodeficiency virus type 1 from subtypes A, B, C, D, E, F, and I: Lack of direct correlation between neutralization serotypes and genetic subtypes and evidence for prevalent serum-dependent infectivity enhancement
(1996)Human immunodeficiency virus type 1 (HIV-1) M group strains have been assigned to date to nine distinct genetic subtypes, designated A through I, according to phylogenetic analyses of nucleotide sequences of their env or ...

A quorum sensing regulated small volatile molecule reduces acute virulence and promotes chronic infection phenotypes
(2011)A significant number of environmental microorganisms can cause serious, even fatal, acute and chronic infections in humans. The severity and outcome of each type of infection depends on the expression of specific bacterial ...
