Epigenetic downregulation of human disabled homolog 2 switches TGF-beta from a tumor suppressor to a tumor promoter
(AMER SOC CLINICAL INVESTIGATION INC, 2010-08)The cytokine TGF-beta acts as a tumor suppressor in normal epithelial cells and during the early stages of tumorigenesis. During malignant progression, cancer cells can switch their response to TGF-beta and use this cytokine ... -
DNA Damage Activates a Spatially Distinct Late Cytoplasmic Cell-Cycle Checkpoint Network Controlled by MK2-Mediated RNA Stabilization
(CELL PRESS, 2010-10-08)Following genotoxic stress, cells activate a complex kinase-based signaling network to arrest the cell cycle and initiate DNA repair. p53-defective tumor cells rewire their checkpoint response and become dependent on the ... -
Modeling evolutionary dynamics of epigenetic mutations in hierarchically organized tumors.
(PUBLIC LIBRARY SCIENCE, 2011-05-05)The cancer stem cell (CSC) concept is a highly debated topic in cancer research. While experimental evidence in favor of the cancer stem cell theory is apparently abundant, the results are often criticized as being difficult ... -
Activation of Aurora-A Kinase by Protein Partner Binding and Phosphorylation Are Independent and Synergistic
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2012-01-06)Protein kinases are activated by phosphorylation and by the binding of activator proteins. The interplay of these two factors is incompletely understood. We applied energetic analysis to this question and characterized the ... -
Impact of the cystic fibrosis mutation F508del-CFTR on renal cyst formation and growth.
(AMER PHYSIOLOGICAL SOC, 2012-10-15)In autosomal dominant polycystic kidney disease (ADPKD), cystic fibrosis transmembrane conductance regulator (CFTR), the protein product of the gene defective in cystic fibrosis (CF), plays a crucial role in fluid accumulation, ... -
The Anaphase Promoting Complex Contributes to the Degradation of the S. cerevisiae Telomerase Recruitment Subunit Est1p
(PUBLIC LIBRARY SCIENCE, 2013-01-25)Telomerase is a multi-subunit enzyme that reverse transcribes telomere repeats onto the ends of linear eukaryotic chromosomes and is therefore critical for genome stability. S. cerevisiae telomerase activity is cell-cycle ... -
Breast reconstruction and post-mastectomy radiation practice
(BIOMED CENTRAL LTD, 2013-03-02)Purpose: The goal of this study was to explore the perspectives and practice of radiation oncologists who treat breast cancer patients who have had breast reconstruction. Methods: In 2010, an original electronic survey was ... -
Optical photon transport in powdered-phosphor scintillators. Part II. Calculation of single-scattering transport parameters
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2013-04)Purpose: Monte Carlo methods based on the Boltzmann transport equation (BTE) have previously been used to model light transport in powdered-phosphor scintillator screens. Physically motivated guesses or, alternatively, the ... -
Optical photon transport in powdered-phosphor scintillators. Part 1. Multiple-scattering and validity of the Boltzmann transport equation
(AMER ASSOC PHYSICISTS MEDICINE AMER INST PHYSICS, 2013-04)Purpose: In Part 1 of this two-part work, predictions for light transport in powdered-phosphor screens are made, based on three distinct approaches. Predictions of geometrical optics-based ray tracing through an explicit ... -
14-3-3 Proteins Interact with a Hybrid Prenyl-Phosphorylation Motif to Inhibit G Proteins
(Elsevier BV, 2013-04-01)Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol. Rnd proteins are atypical ... -
Genetic Tracing via DNGR-1 Expression History Defines Dendritic Cells as a Hematopoietic Lineage
(CELL PRESS, 2013-08-15)Mononuclear phagocytes are classified as macrophages or dendritic cells (DCs) based on cell morphology, phenotype, or select functional properties. However, these attributes are not absolute and often overlap, leading to ... -
Re-challenge chemotherapy with gemcitabine plus carboplatin in patients with non-small cell lung cancer.
(2013-10)Despite recent improvements to current therapies and the emergence of novel agents to manage advanced non-small cell lung cancer (NSCLC), the patients' overall survival remains poor. Re-challenging with first-line chemotherapy ... -
Deciphering intratumor heterogeneity and temporal acquisition of driver events to refine precision medicine
(BIOMED CENTRAL LTD, 2014)The presence of multiple subclones within tumors mandates understanding of longitudinal and spatial subclonal dynamics. Resolving the spatial and temporal heterogeneity of subclones with cancer driver events may offer ... -
Immunomodulatory agents lenalidomide and pomalidomide co-stimulate T cells by inducing degradation of T cell repressors Ikaros and Aiolos via modulation of the E3 ubiquitin ligase complex CRL4(CRBN.).
(WILEY, 2014-03-01)Cereblon (CRBN), the molecular target of lenalidomide and pomalidomide, is a substrate receptor of the cullin ring E3 ubiquitin ligase complex, CRL4(CRBN) . T cell co-stimulation by lenalidomide or pomalidomide is cereblon ... -
ATM mutation rather than BIRC3 deletion and/or mutation predicts reduced survival in 11q-deleted chronic lymphocytic leukemia: data from the UK LRF CLL4 trial
(2014-04)ATM mutation and BIRC3 deletion and/or mutation have independently been shown to have prognostic significance in chronic lymphocytic leukemia. However, the relative clinical importance of these abnormalities in patients ... -
