The 5′ regulatory region of the human fetal globin genes is a gene conversion hotspot
(2008)The human fetal globin genes consist of the first mammalian genomic loci for which gene conversion was reported. To date, 14 gene conversions have been described in the human Gγ- and Aγ-globin genes, the vast majority of ... -
Aberrant methylation of c-myc and c-fos protooncogenes and p53 tumor suppressor gene in myelodysplastic syndromes and acute non-lymphocytic leukemia
(2003)Purpose: Aberrant methylation, as an epigenetic phenomenon, may precede and regulate the expression of genes involved in transformation mechanisms that lead to leukemogenesis of hemopoietic cells. The genes involved mostly ... -
Achilles, a new family of transcriptionally active retrotransposons from the olive fruit fly, with y chromosome preferential distribution
(2015)Sex chromosomes have many unusual features relative to autosomes. The in depth exploration of their structure will improve our understanding of their origin and divergence (degeneration) as well as the evolution of genetic ... -
Calcitriol Suppresses HIF-1 and HIF-2 Transcriptional Activity by Reducing HIF-1/2α Protein Levels via a VDR-Independent Mechanism
(2020)Hypoxia-inducible transcription factors 1 and 2 (HIFs) are major mediators of cancer development and progression and validated targets for cancer therapy. Although calcitriol, the biologically active metabolite of vitamin ... -
Cold shock Y-box protein-1 proteolysis autoregulates its transcriptional activities
(2013)Background: The Y-box protein-1 (YB-1) fulfills pleiotropic functions relating to gene transcription, mRNA processing, and translation. It remains elusive how YB-1 shuttling into the nuclear and cytoplasmic compartments ... -
Developing Reflexivity through Group Processes in Psychotherapy Training: An Interpretative Phenomenological Analysis of Systemic Family Therapy Trainees’ Experience
(2021)Constructionist approaches in the field of systemic family therapy prioritize reflexivity to promote personal development within training, often leaning on group processes. Drawing from a qualitative study we conducted to ... -
DIANA-mirExTra v2.0: Uncovering microRNAs and transcription factors with crucial roles in NGS expression data
(2016)Differential expression analysis (DEA) is one of the main instruments utilized for revealing molecular mechanisms in pathological and physiological conditions. DIANA-mirExTra v2.0 (http://www.microrna. gr/mirextrav2) ... -
DIANA-miRGen v4: Indexing promoters and regulators for more than 1500 microRNAs
(2021)Deregulation of microRNA (miRNA) expression plays a critical role in the transition from a physiological to a pathological state. The accurate miRNA promoter identification in multiple cell types is a fundamental endeavor ... -
Discovery and characterization of 2-anilino-4- (thiazol-5-yl)pyrimidine transcriptional CDK inhibitors as anticancer agents
(2010)The main difficulty in the development of ATP antagonist kinase inhibitors is target specificity, since the ATP-binding motif is present in many proteins. We introduce a strategy that has allowed us to identify compounds ... -
Enhancer of rudimentary homologue interacts with scaffold attachment factor B at the nuclear matrix to regulate SR protein phosphorylation
(2017)Scaffold attachment factor B1 (SAFB1) is an integral component of the nuclear matrix of vertebrate cells. It binds to DNA on scaffold/matrix attachment region elements, as well as to RNA and a multitude of different proteins, ... -
Epigenetic regulation of apoptosis via the PARK7 interactome in peripheral blood mononuclear cells donated by tuberculosis patients vs. healthy controls and the response to treatment: A systems biology approach
(2020)Aims: The aims of our study were to determine for the first time differentially expressed genes (DEGs) and enriched molecular pathways involving the PARK7 interactome in PBMCs donated from tuberculosis patients. Methods: ... -
ERK signaling controls productive HIF-1 binding to chromatin and cancer cell adaptation to hypoxia through HIF-1α interaction with NPM1
(2021)The hypoxia-inducible factor HIF-1 is essential for oxygen homeostasis. Despite its well-understood oxygen-dependent expression, regulation of its transcriptional activity remains unclear. We show that phosphorylation by ... -
Expression of human serum albumin (HSA) mRNA in human granulosa cells: Potential correlation of the 95 amino acid long carboxyl terminal of HSA to gonadotrophin surge-attenuating factor
(2006)Introduction: According to previous studies, gonadotrophin surge-attenuating factor (GnSAF), which is assumed to be produced in human granulosa cells, has a homology with the carboxyl terminal of the human serum albumin ... -
Functional characterization of the hGRαT556I causing Chrousos syndrome
(2016)Background: Chrousos syndrome is a rare pathologic condition characterized by generalized, partial resistance of target tissues to glucocorticoids and caused by inactivating mutations of the human glucocorticoid receptor ... -
HIF-2α phosphorylation by CK1δ promotes erythropoietin secretion in liver cancer cells under hypoxia
(2016)Hypoxia inducible factor 2 (HIF-2) is a transcriptional activator implicated in the cellular response to hypoxia. Regulation of its inducible subunit, HIF-2α (also known as EPAS1), involves posttranslational modifications. ... -
Host – virus – drug interactions as determinants of COVID-19’s phenotypes: A data-driven hypothesis
(2020)There is a growing body of evidence on the significance of interactions between comorbidities, their treatments and COVID-19 clinical phenotypes. The hypothesis explored herein is that pharmaceutical compounds currently ... -
Hypoxia-induced Changes in SUMO Conjugation Affect Transcriptional Regulation under Low Oxygen
(2019)Hypoxia occurs in pathological conditions, such as cancer, as a result of the imbalance between oxygen supply and consumption by proliferating cells. HIFs are critical molecular mediators of the physiological response to ... -
Immunoglobulin genes in multiple myeloma: Expressed and non-expressed repertoires, heavy and light chain pairings and somatic mutation patterns in a series of 101 cases
(2006)Background and Objectives. The available data on the immunoglobulin gene (IG) repertoire in multiple myeloma (MM) derive mainly from heavy chains; considerably less is known about light chains. We assessed in parallel IGH ... -
