4-Arylazo-3,5-diamino-1H-pyrazole CDK inhibitors: SAR study, crystal structure in complex with CDK2, selectivity, and cellular effects
(2006)In a routine screening of our small-molecule compound collection we recently identified 4-arylazo-3,5-diamino-1H-pyrazoles as a novel group of ATP antagonists with moderate potency against CDK2-cyclin E. A preliminary SAR ... -
Activation of FADD-Dependent neuronal death pathways as a predictor of pathogenicity for LRRK2 mutations
(2016)Background Despite the plethora of sequence variants in LRRK2, only a few clearly segregate with PD. Even within this group of pathogenic mutations, the phenotypic profile can differ widely. Objective We examined multiple ... -
Allopurinol protects human glomerular endothelial cells from high glucose-induced reactive oxygen species generation, p53 overexpression and endothelial dysfunction
(2018)Purpose: Mitochondrial reactive oxygen species (ROS) overproduction in capillary endothelial cells is a prerequisite for the development of diabetic nephropathy. Inhibition of xanthine oxidase, another ROS generator, ... -
Ancestral Absence of Electron Transport Chains in Patescibacteria and DPANN
(2020)Recent discoveries suggest that the candidate superphyla Patescibacteria and DPANN constitute a large fraction of the phylogenetic diversity of Bacteria and Archaea. Their small genomes and limited coding potential have ... -
CB1R-dependent activation of Fyn tyrosine kinase and protein kinase C Delta, PKCδ, in lipid rafts
(2008)Cannabinoid 1 receptors (CB1Rs) are heptahelical transmembrane receptors which may exert their effects through the activation of the extracellular signal-regulated kinases (ERKs). We have previously shown that stably ... -
Crystalline silica activates the T-cell and the B-cell antigen receptor complexes and induces T-cell and B-cell proliferation
(2019)Silicosis is an occupational fibrotic lung disease, which is associated with an increased incidence of autoimmune diseases. The effect of crystalline silica on the immune system is thought to be mediated by the antigen ... -
Curcumin mediates attenuation of pro-inflammatory interferon γ and interleukin 17 cytokine responses in psoriatic disease, strengthening its role as a dietary immunosuppressant
(2020)Curcumin exhibits anti-inflammatory properties and has been used for centuries in traditional medicine and as dietary supplement. Data from clinical trials has strengthened the notion that curcumin may exert an anti-inflammatory ... -
Denominator changes may obscure results from single-well assays: β3-adrenoceptor ligand-induced changes of cell number as example
(2017)[No abstract available] -
Discovery of N-Phenyl-4-(thiazol-5-yl)pyrimidin-2-amine aurora kinase inhibitors
(2010)Through cell-based screening of our kinase-directed compound collection, we discovered that a subset of N-phenyl-4-(thiazol-5-yl)pyrimidin-2-amines were potent cytotoxic agents against cancer cell lines, suppressed mitotic ... -
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 ... -
Energy handling in renal tubular epithelial cells of the hamster, a native hibernator, under warm anoxia or reoxygenation
(2018)Ischemia-reperfusion (I-R) injury causes several diseases, including acute kidney injury. Hibernating mammals survive periods of torpor with a marked drop in tissue perfusion, interspersed with periods of arousal, and ... -
Enhanced Ca2+ Entry Sustains the Activation of Akt in Glucose Deprived SH-SY5Y Cells
(2022)The two crucial cellular insults that take place during cerebral ischemia are the loss of oxygen and loss of glucose, which can both activate a cascade of events leading to neuronal death. In addition, the toxic overactivation ... -
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, ... -
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 ... -
Estimating the total number of phosphoproteins and phosphorylation sites in eukaryotic proteomes
(2017)Background: Phosphorylation is the most frequent post-translational modification made to proteins and may regulate protein activity as either a molecular digital switch or a rheostat. Despite the cornucopia of high-throughput ... -

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-induced changes in plasma micro-RNAs correlate with pulmonary artery pressure at high altitude
(2018)In vitro and animal studies revealed micro-RNAs (miRs) to be involved in modulation of hypoxia-induced pulmonary hypertension (HPH). However, knowledge of circulating miRs in humans in the context of HPH is very limited. ... -
Hypoxia-inducible factors and the regulation of lipid metabolism
(2019)Oxygen deprivation or hypoxia characterizes a number of serious pathological conditions and elicits a number of adaptive changes that are mainly mediated at the transcriptional level by the family of hypoxia-inducible ...
