Case Report of Transmissible Gastroenteritis Coronavirus Infection Associated with Small Intestine and Brain Lesions in Piglets
(2019)This case study report describes a transmissible gastroenteritis coronavirus (TGEV) infection presented in a commercial pig herd. The clinical signs of infection appeared in newborn piglets, including medium morbidity and ... -
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 ... -
Dysregulation of caveolin-1 phosphorylation and nuclear translocation is associated with senescence onset
(2021)We recently reported that the inability of osteoarthritic (OA) chondrocytes to repair oxidative stress (OS) induced DNA damage is linked to Cav-1 overexpression/improper localization. We speculated that the senescent status ... -
ERK1/2 phosphorylates HIF-2α and regulates its activity by controlling its CRM1-dependent nuclear shuttling
(2019)Hypoxia-inducible factor 2 (HIF-2) is a principal component of the cellular response to oxygen deprivation (hypoxia). Its inducible subunit, HIF-2α (also known as EPAS1), is controlled by oxygen-dependent as well as ... -
Evidence for disulfide bonds in SR Protein Kinase 1 (SRPK1) that are required for activity and nuclear localization
(2017)Serine/arginine protein kinases (SRPKs) phosphorylate Arg/Ser dipeptide-containing proteins that play crucial roles in a broad spectrum of basic cellular processes. The existence of a large internal spacer sequence that ... -
Exp5 exports eEF1A via tRNA from nuclei and synergizes with other transport pathways to confine translation to the cytoplasm
(2002)Importin β-type transport receptors mediate the vast majority of transport pathways between cell nucleus and cytoplasm. We identify here the translation elongation factor 1A (eEF1A) as the predominant nuclear export substrate ... -
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. ... -
Hypoxia upregulates the expression of the O-linked N-acetylglucosamine containing epitope H in human ependymal cells
(2011)Epitope H contains an O-linked N-acetylglucosamine (O-GlcNAc) residue in a specific conformation and/or environment recognized by mouse IgM monoclonal antibody H (mabH). Epitope H is present in several types of cells and ... -
Inter-species functional Interactome of nuclear Steroid receptors (R1)
(2018)Steroids exert their actions by binding to the glucocorticoid, mineralocorticoid, androgen, estrogen and progesterone classes of receptors. Despite an exponential increase in our knowledge of steroid receptors, their ... -
Lncrnas as chromatin regulators in cancer: From molecular function to clinical potential
(2019)During the last decade, high-throughput sequencing efforts in the fields of transcriptomics and epigenomics have shed light on the noncoding part of the transcriptome and its potential role in human disease. Regulatory ... -
Mortalin-mediated and ERK-controlled targeting of HIF-1α to mitochondria confers resistance to apoptosis under hypoxia
(2017)Hypoxia inducible factor-1 (HIF-1) is the main transcriptional activator of the cellular response to hypoxia and an important target of anticancer therapy. Phosphorylation by ERK1 and/or ERK2 (MAPK3 and MAPK1, respectively; ... -
Novel HIF-2α interaction with Reptin52 impairs HIF-2 transcriptional activity and EPO secretion
(2021)Hypoxia-inducible factor 2 (HIF-2), is essential for cellular response to hypoxia and holds an important role in erythropoiesis, angiogenesis, tissue invasion and metastasis, thus, constituting an important therapeutic ... -
Nuclear localization of cytokeratin 8 and the O-linked N -acetylglucosamine-containing Epitope H in epithelial cells of infiltrating ductal breast carcinomas: A combination of immunogold and EDTA regressive staining methods
(2006)In a previous study, the authors have shown cytokeratin 8 (CK8) and epitope H ultrastructural localization in breast cancer cell nuclei. Epitope H contains an O-linked N -acetylglucosamine (O-GlcNAc) residue in a specific ... -
Potential dissociative glucocorticoid receptor activity for protopanaxadiol and protopanaxatriol
(2019)�Glucocorticoids are steroid hormones that regulate inflammation, growth, metabolism, and apoptosis via their cognate receptor, the glucocorticoid receptor (GR). GR, acting mainly as a transcription factor, activates or ... -
Proteomic analysis of human angiogenin interactions reveals cytoplasmic PCNA as a putative binding partner
(2017)Human Angiogenin (hAng) is a member of the ribonuclease A superfamily and a potent inducer of neovascularization. Protein interactions of hAng in the nucleus and cytoplasm of the human umbilical vein cell line EA.hy926 ... -
The triterpene echinocystic acid and its 3-O-glucoside derivative are revealed as potent and selective glucocorticoid receptor agonists
(2016)Glucocorticoids are steroid hormones widely used to control many inflammatory conditions. These effects are primarily attributed to glucocorticoid receptor transrepressional activities but with concomitant receptor ...
