RET proto-oncogene mutations are restricted to codon 618 in Cypriot families with multiple endocrine neoplasia 2
(2011)Background: RET germline mutations predispose to the development of inherited cancer syndrome multiple endocrine neoplasia type 2 (MEN2). Several variants of the RET proto-oncogene including G691S and S904S have been ...

Retinoid X receptor-γ gene expression is developmentally regulated in the embryonic rodent peripheral nervous system
(1998)The retinoid X receptor-γ (RXRγ) is a transcription factor that belongs to the thyroid hormone/retinoid family of nuclear receptors. Previous studies have shown that RXRγ is expressed in the developing peripheral nervous ...

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 ...

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 ...

Revisiting the saproxylic beetle ‘Propomacrus cypriacus Alexis & Makris, 2002’ (Coleoptera: Euchiridae) using molecular, morphological and ecological data
(2017)Propomacrus cypriacus a saproxylic beetle endemic to Cyprus, was described as a species distinct from P. bimucronatus on the basis of a few morphological characters and has been evaluated as Critically Endangered by IUCN, ...

RNA intereference: A powerful laboratory tool and its therapeutic implications
(2006)Ever since RNA intereference (RNAi) was discovered in the early 1990s, a number of scientists from the academic and biotechnology world have continued to view it as the revolutionary discovery of the century. Unequivocally, ...

Role of conserved intracellular motifs in Serrate signalling, cis-inhibition and endocytosis
(2006)Notch is the receptor in a signalling pathway that operates in a diverse spectrum of developmental processes. Its ligands (e.g. Serrate) are transmembrane proteins whose signalling competence is regulated by the ...

The role of ecological specialization in shaping patterns of insular communities
(Wiley, 2020-09-30)Aim: Research on the response of species richness to area and environmental heterogeneity so far has not addressed possible effects of species’ differences in ecological specialization. Herein we provide a new metric, ...

The role of molecular genetics in diagnosing familial hematuria(s)
(2012)Familial microscopic hematuria (MH) of glomer-ular origin represents a heterogeneous group of monogenic conditions involving several genes, some of which remain unknown. Recent advances have increased our understanding and ...

Article
Role of Rb-dependent and Rb-independent functions of papillomavirus E7 oncogene in head and neck cancer
(2007)Infection with high-risk human papillomaviruses (HPV) and in particular the expression of the viral proteins E6 and E7 have been associated with the etiology of a subset of head and neck squamous cell cancer (HNSCC). ...

Roles for genomic imprinting and the zygotic genome in placental development
(2001)The placenta contains several types of fetomaternal interfaces where zygote-derived cells interact with maternal cells or maternal blood for the promotion of fetal growth and viability. The genetic factors regulating the ...

Rotenoids mediate potent cancer chemopreventive activity through transcriptional regulation of ornithine decarboxylase
(1995)For the discovery of new cancer chemopreventive agents, we have studied the potential of plant extracts to inhibit phorbol ester-induced ornithine decarboxylase (ODC) activity in cell culture. Four active rotenoids were ...

Samba, a Xenopus hnRNP expressed in neural and neural crest tissues
(2009)RNA binding proteins regulate gene expression at the posttranscriptional level and play important roles in embryonic development. Here, we report the cloning and expression of Samba, a Xenopus hnRNP that is maternally ...

Screening for Familial Mediterranean Fever M694V and V726A mutations in the Greek population.
(2009)Familial Mediterranean Fever (FMF) is an autosomal recessive genetic disease that primarily affects populations surrounding the Mediterranean basin. FMF patients suffer from recurrent episodes of fever accompanied by ...

Screening for mutations in kidney-related genes using SURVEYOR nuclease for cleavage at heteroduplex mismatches
(2009)SURVEYOR is a new mismatch-specific plant DNA endonuclease that is very efficient for mutation scanning in heteroduplex DNA. It is much faster, cheaper, more sensitive, and easier to perform than other "traditional" mutation ...

Screening of the PKD1 duplicated region reveals multiple single nucleotide polymorphisms and a de novo mutation in Hellenic polycystic kidney disease families.
(2000)Mutations in the PKD1 gene account for approximately 85% of cases with autosomal dominant polycystic kidney disease (ADPKD1

Selection of cancer chemopreventive agents based on inhibition of topoisomerase II activity
(2000)The present study was undertaken to determine if in vitro inhibition of one or both of the two most dominant mammalian DNA topoisomerases (topos) is common among chemopreventive agents. To determine if an agent was a topo ...

Selective activation of TNFR1 and NF-ΚB inhibition by a novel biyouyanagin analogue promotes apoptosis in acute leukemia cells
(2016)Background: Acquired resistance towards apoptosis is a hallmark of cancer. Elimination of cells bearing activated oncogenes or stimulation of tumor suppressor mediators may provide a selection pressure to overcome resistance. ...
