Regulation of CDKN2B expression by interaction of Arnt with Miz-1 - a basis for functional integration between the HIF and Myc gene regulatory pathways
(Peer reviewed; Journal article, 2014-03-11)Background: Hypoxia- and Myc-dependent transcriptional regulatory pathways are frequently deregulated in cancer cells. These pathways converge in many cellular responses, but the underlying molecular mechanisms are unclear. ... -
Regulation of tyrosine hydroxylase is preserved across different homo- and heterodimeric 14-3-3 proteins
(Peer reviewed; Journal article, 2016-05)Tyrosine hydroxylase (TH) is regulated by members of the 14-3-3 protein family. However, knowledge about the variation between 14-3-3 proteins in their regulation of TH is still limited. We examined the binding, effects ... -
Regulatory Peptides from Chromogranin A and Secretogranin II
(Peer reviewed; Journal article, 2010)This commentary is focusing on novel aspects on the secreted CgA- and SgII-derived peptides, vasostatin-I (bovine and human CgA1–76, VS-I), WE-14 (CgA316–329), catestatin (bovine CgA344–366, human CgA352–372, Cts) and the ... -
Regulatory post-translational modifications and protein-protein interactions involved in function and proteostasis of aromatic amino acid hydroxylases
(Doctoral thesis, 2021-09-16)The non-heme iron and (6R)-L-erythro-5,6,7,8-tetrahydrobiopterin (BH4) dependent aromatic amino acid hydroxylases (AAAHs) family of enzymes include phenylalanine hydroxylase (PAH), tyrosine hydroxylase (TH), and tryptophan ... -
The Regulatory Subunit of PKA-I Remains Partially Structured and Undergoes b-Aggregation upon Thermal Denaturation
(Peer reviewed; Journal article, 2011-03-04)Background: The regulatory subunit (R) of cAMP-dependent protein kinase (PKA) is a modular flexible protein that responds with large conformational changes to the binding of the effector cAMP. Considering its highly dynamic ... -
Release of tensile strain on engineered human tendon tissue disturbs cell adhesions, changes matrix architecture, and induces an inflammatory phenotype
(Peer reviewed; Journal article, 2014-01-21)Mechanical loading of tendon cells results in an upregulation of mechanotransduction signaling pathways, cell-matrix adhesion and collagen synthesis, but whether unloading removes these responses is unclear. We investigated ... -
Relevance of Electrostatics for the Interaction of Tyrosine Hydroxylase with Porous Silicon Nanoparticles
(Journal article; Peer reviewed, 2021)Tyrosine hydroxylase (TH) is the enzyme catalyzing the rate-limiting step in the synthesis of dopamine in the brain. Developing enzyme replacement therapies using TH could therefore be beneficial to patient groups with ... -
Reliable FASP-based procedures for optimal quantitative proteomic and phosphoproteomic analysis on samples from acute myeloid leukemia patients
(Peer reviewed; Journal article, 2016-06-21)Background Satisfactory sample preparation for mass spectrometry-based analysis is a critical step in the proteomics workflow. The quality and reproducibility of sample preparation can determine the coverage and confidence ... -
Remote postconditioning by humoral factors in effluent from ischemic preconditioned rat hearts is mediated via PI3K/Akt-dependent cell-survival signaling at reperfusion
(Peer reviewed; Journal article, 2010-12-29)Short non-lethal ischemic episodes administered to hearts prior to (ischemic preconditioning, IPC) or directly after (ischemic postconditioning, IPost) ischemic events facilitate myocardial protection. Transferring coronary ... -
Replication protein A prevents accumulation of single-stranded telomeric DNA in cells that use alternative lengthening of telomeres
(Peer reviewed; Journal article, 2007-10-24)The activation of a telomere maintenance mechanism is required for cancer development in humans. While most tumors achieve this by expressing the enzyme telomerase, a fraction (5–15%) employs a recombination-based mechanism ... -
A reproducible brain tumour model established from human glioblastoma biopsies
(Peer reviewed; Journal article, 2009-12-29)Background: Establishing clinically relevant animal models of glioblastoma multiforme (GBM) remains a challenge, and many commonly used cell line-based models do not recapitulate the invasive growth patterns of patient ... -
Resibufogenin Targets the ATP1A1 Signaling Cascade to Induce G2/M Phase Arrest and Inhibit Invasion in Glioma
(Journal article; Peer reviewed, 2022)Resibufogenin (RB) is a major active ingredient in the traditional Chinese medicine Chansu and has garnered considerable attention for its efficacy in the treatment of cancer. However, the anticancer effects and underlying ... -
Revealing and Harnessing Tumour-Associated Microglia/Macrophage Heterogeneity in Glioblastoma
(Journal article; Peer reviewed, 2020)Cancer heterogeneity and progression are subject to complex interactions between neoplastic cells and their microenvironment, including the immune system. Although glioblastomas (GBMs) are classified as ‘cold tumours’ with ... -
Riboswitches as Drug Targets for Antibiotics
(Journal article; Peer reviewed, 2021)Riboswitches reside in the untranslated region of RNA and regulate genes involved in the biosynthesis of essential metabolites through binding of small molecules. Since their discovery at the beginning of this century, ... -
Right ventricular postsystolic shortening: Resolution after opening a totally occluded right coronary artery
(Journal article; Peer reviewed, 2022)Acute myocardial ischemia induces reduced systolic shortening and causes postsystolic shortening (PSS). Right ventricular (RV) PSS in coronary artery disease has been less studied. We present here the case of a 51-year-old ... -
