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 ... -
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 ... -
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: ... -
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 ... -
Identification of MAPK phosphorylation sites and their role in the localization and activity of hypoxia-inducible factor-1α
(2006)Hypoxia-inducible factor 1 (HIF-1) controls the expression of most genes induced by hypoxic conditions. Regulation of expression and activity of its inducible subunit, HIF-1α, involves several post-translational modifications. ... -
Protein phosphatase PPP3CA (calcineurin A) down-regulates hypoxia-inducible factor transcriptional activity
(2019)Hypoxia-inducible factors (HIF) are master regulators of the response to hypoxia. Although several kinases are known to modify their oxygen sensitive HIF-α subunits or affect indirectly their function, little is known about ... -
Role of Arc1p in the modulation of yeast glutamyl-tRNA synthetase activity
(2005)Yeast methionyl-tRNA synthetase (MetRS) and glutamyl-tRNA synthetase (GluRS) possess N-terminal extensions that bind the cofactor Arc1p in trans. The strength of GluRS-Arc1p interaction is high enough to allow copurification ... -
Transcription of the NKG2D ligand MICA is suppressed by the IRE1/XBP1 pathway of the unfolded protein response through the regulation of E2F1
(2019)The unfolded protein response (UPR) is an adaptive signaling pathway activated in response to endoplasmic reticulum (ER) stress. The effectors of the UPR are potent transcription activators; however, some genes are suppressed ... -
Transcriptional over-expression of chloride intracellular channels 3 and 4 in malignant pleural mesothelioma
(2015)Background Chloride Intracellular Channels (CLICs) are contributing to the regulation of multiple cellular functions. CLICs have been found over-expressed in several malignancies, and therefore they are currently considered ...
