In vivo high-resolution magic angle spinning magnetic resonance spectroscopy of Drosophila melanogaster at 14.1 T shows trauma in aging and in innate immune-deficiency is linked to reduced insulin signaling
(2010)In vivo magnetic resonance spectroscopy (MRS), a non-destructive biochemical tool for investigating live organisms, has yet to be used in the fruit fly Drosophila melanogaster, a useful model organism for investigating ...

Familial Mediterranean fever associated pyrin mutations in Greece
(2003)Objective: To search for pyrin mutations associated with familial Mediterranean fever (FMF) in Greece. Patients and methods: 62 patients fulfilling the Tel Hashomer diagnostic criteria for definite (33) or probable (29) ...

Article
Compositional dissimilarity patterns of reptiles and amphibians in insular systems around the world
(2013)Several studies have shown that taxa with poor dispersal ability have a higher level of compositional dissimilarity than good dispersers. However, compositional dissimilarity patterns between islands with respect to dispersal ...

Article
Molecular phylogeny and phylogeography of the Greek populations of the genus orthometopon (isopoda, oniscidea) based on mitochondrial DNA sequences
(2008)We infer phylogenetic relationships among isopod species of the genus Orthometopon distributed in the Greek area, comparing partial mitochondrial DNA sequences for cytochrome oxidase I (COI). All phylogenetic analyses ...

Community variation of spiders, beetles and isopods in three small island groups of the Aegean Sea: the interplay between history and ecology
(2017)Aim: To study the variation in the species turnover and nestedness components of compositional dissimilarity in a multi-taxa and multi-island-group system. In addition, to examine the influence of several biogeographical ...

Article
Ets2-dependent trophoblast signalling is required for gastrulation progression after primitive streak initiation
(2013)Although extraembryonic ectoderm trophoblast signals the embryo for primitive streak initiation, a prerequisite for gastrulation, it is unknown whether it also signals for the progression of gastrulation after primitive ...

Between-island compositional dissimilarity of avian communities
(2014)Compositional dissimilarity patterns of biotic communities can vary among different types of insular systems and among taxa with different dispersal abilities. In this work we examined compositional dissimilarity patterns ...

A review of phylogeographic analyses of animal taxa from the aegean and surrounding regions
(2015)We provide a review and synthesis of key findings in phylogeographic research on terrestrial animals in the Aegean archipelago (Greece) and surrounding regions (Greek mainland, southern Balkans and Asia Minor). A critical ...

Article
Developmental biology: Our fly cousins' gut
(2008)What do we humans have in common with flies? Quite a lot, at least at the cellular and molecular levels. Our intestine, for instance, is similar to that of the fly, not only in function but also in its development and ...

Article
The interplay between DSL proteins and ubiquitin ligases in Notch signaling
(2005)Lateral inhibition is a pattern refining process that generates single neural precursors from a field of equipotent cells and is mediated via Notch signaling. Of the two Notch ligands Delta and Serrate, only the former was ...

Article
Embryonic multipotent progenitors remodel the Drosophila airways during metamorphosis
(2010)Adult structures in holometabolous insects such as Drosophila are generated by groups of imaginal cells dedicated to the formation of different organs. Imaginal cells are specified in the embryo and remain quiescent until ...

Article
The homeobox transcription factor cut coordinates patterning and growth during drosophila airway remodeling
(2013)A fundamental question in developmental biology is how tissue growth and patterning are coordinately regulated to generate complex organs with characteristic shapes and sizes. We showed that in the developing primordium ...

Article
Reversal of ER-β silencing by chromatin modifying agents overrides acquired tamoxifen resistance
(2013)The purpose of this work is to determine the molecular mechanisms underlying tamoxifen resistance. We show here that ER-β is epigenetically silenced in a cell line with acquired tamoxifen resistance (MCF-7/TAM-R) and this ...

Article
Significant pairwise co-occurrence patterns are not the rule in the majority of biotic communities
(2012)Our aim was to investigate species co-occurrence patterns in a large number of published biotic communities, in order to document to what extent species associations can be found in presence-absence matrices. We also aim ...

Breast Cancer Epigenetics
(Elsevier Inc., 2015)The molecular mechanisms underlying the development and progression of breast cancer are far from being understood. It is obvious that the initiation of breast cancer as well as its transition toward distinct breast cancer ...

Article
Clinico-pathological correlations in 127 patients in 11 large pedigrees, segregating one of three heterozygous mutations in the COL4A3 COL4A4 genes associated with familial haematuria and significant late progression to proteinuria and chronic kidney disease from focal segmental glomerulosclerosis
(2009)Background. Heterozygous mutations in the COL4A3 COL4A4 genes are currently thought to be responsible for familial benign microscopic haematuria and maintenance of normal long-term kidney function.Methods. We report on 11 ...

Evidence that a metabolilte of equine estrogens, 4-hydroxyequilenin, induces cellular transformation in vitro
(2001)Estrogen replacement therapy has been correlated with an increased risk of developing hormone-dependent cancers. 4-Hydroxyequilenin (4-OHEN) is a catechol metabolite of equilenin and equilin which are components of the ...

Homeostasis in Infected Epithelia: Stem Cells Take the Lead
(2009)To maintain tissue homeostasis and avoid disease, epithelial cells damaged by pathogens need to be readily replenished, and this is mainly achieved by the activation of stem cells. In this Short Review, we discuss recent ...
