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 ... -
Conformational properties of HIV-1 gp120/V3 immunogenic domains
(2005)Infection of target host cells by the human immunodeficiency virus-1 (HIV-1) is a multi-step process involving a series of conformational changes in the viral gp120 and gp41 proteins. Gp120 binding to the main cell receptor, ... -
DIANA-LncBase v3: Indexing experimentally supported miRNA targets on non-coding transcripts
(2020)DIANA-LncBase v3.0 (www.microrna.gr/LncBase) is a reference repository with experimentally supported miRNA targets on non-coding transcripts. Its third version provides approximately half a million entries, corresponding ... -
Dynamic changes of CTCs in patients with metastatic HR(+)/HER2(−) breast cancer receiving salvage treatment with everolimus/exemestane
(2021)Purpose: Detection of CTCs represents a poor prognostic factor in patients with early and metastatic breast cancer (mBC) and treatment with everolimus–exemestane (E/E) is an established effective treatment in hormone ... -
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 ... -
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 ... -
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 ... -
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 ... -
Mechanisms of action of differentiation inducers: Detection of inducer binding protein(s) in murine erythroleukemia cells
(2005)We have shown previously that murine erythroleukemia (MEL) and human neuroectodermal RD/TE-671 cells are induced to differentiate by ureido derivatives of pyridine (UDPs) and may contain inducer binding protein(s). In the ... -
Molecular proteomic characterization of a pediatric medulloblastoma xenograft
(2017)Background/Aim: Medulloblastoma (MBL), an archetypal primitive neuroectodermal tumor of the cerebellum, is the most common pediatric central nervous system malignancy representing approximately 20% of all childhood brain ... -
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; ... -
Neurotoxic effects of aluminum are associated with its interference with estrogen receptors signaling
(2020)Aluminum compounds have been observed in various brain regions, and their accumulation has been associated with many neurodegenerative disorders. Neurotoxic effects of aluminum are attributed to reactive oxygen species ... -
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 ... -
Quercetin accumulates in nuclear structures and triggers specific gene expression in epithelial cells
(2012)Quercetin is a flavonol modifying a number of cell processes in different cell lines. Here, we present evidence that nonconjugated quercetin enters cells possibly via organic anion transporter polypeptides and quickly ... -
Smad4 and epithelial–mesenchymal transition proteins in colorectal carcinoma: an immunohistochemical study
(2018)Epithelial–mesenchymal transition (EMT) plays an important role in cancer metastasis. During EMT, tumor cells acquire the capacity to migrate and invade the stroma. Activation of the transforming growth factor-b (TGF-b) ...
