Real time fluorescence imaging of PLC gamma translocation and its interaction with the epidermal growth factor receptor
(2001-04-30)The translocation of fluorescently tagged PLC gamma and requirements for this process in cells stimulated with EGF were analyzed using real time fluorescence microscopy applied for the first time to monitor growth factor ... -
Functional coupling of transcription and splicing
(Elsevier BV, 2012-06-01)The tightly regulated process of precursor messenger RNA (pre-mRNA) alternative splicing is a key mechanism to increase the number and complexity of proteins encoded by the genome. Evidence gathered in recent years has ... -
Tumor-Secreted LOXL2 Activates Fibroblasts through FAK Signaling
(AMER ASSOC CANCER RESEARCH, 2013-11-01)Cancer-associated fibroblasts enhance cancer progression when activated by tumor cells through mechanisms not yet fully understood. Blocking mammary tumor cell-derived lysyl oxidase-like 2 (LOXL2) significantly inhibited ... -
BAF180 promotes cohesion and prevents genome instability and aneuploidy.
(CELL PRESS, 2014-03-27)BAF180, a subunit of the PBAF chromatin remodeling complex, is frequently mutated in cancer. Although PBAF regulates transcription, it remains unclear whether this is what drives tumorigenesis in cells lacking BAF180. Based ... -
Origin licensing requires ATP binding and hydrolysis by the MCM replicative helicase.
(CELL PRESS, 2014-09-04)Loading of the six related Minichromosome Maintenance (MCM) proteins as head-to-head double hexamers during DNA replication origin licensing is crucial for ensuring once-per-cell-cycle DNA replication in eukaryotic cells. ... -
Requirement for PBAF in transcriptional repression and repair at DNA breaks in actively transcribed regions of chromatin.
(CELL PRESS, 2014-09-04)Actively transcribed regions of the genome are vulnerable to genomic instability. Recently, it was discovered that transcription is repressed in response to neighboring DNA double-strand breaks (DSBs). It is not known ... -
Sex specific retinoic acid signaling is required for the initiation of urogenital sinus bud development.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2014-11-15)The mammalian urogenital sinus (UGS) develops in a sex specific manner, giving rise to the prostate in the male and the sinus vagina in the embryonic female. Androgens, produced by the embryonic testis, have been shown to ... -
Visualizing cellular imaging data using PhenoPlot.
(NATURE PUBLISHING GROUP, 2015-01-08)Visualization is essential for data interpretation, hypothesis formulation and communication of results. However, there is a paucity of visualization methods for image-derived data sets generated by high-content analysis ... -
Cell shape and the microenvironment regulate nuclear translocation of NF-κB in breast epithelial and tumor cells.
(WILEY, 2015-03-03)Although a great deal is known about the signaling events that promote nuclear translocation of NF-κB, how cellular biophysics and the microenvironment might regulate the dynamics of this pathway is poorly understood. In ... -
TOPBP1 recruits TOP2A to ultra-fine anaphase bridges to aid in their resolution.
(NATURE PUBLISHING GROUP, 2015-03-12)During mitosis, sister chromatids must be faithfully segregated to ensure that daughter cells receive one copy of each chromosome. However, following replication they often remain entangled. Topoisomerase IIα (TOP2A) has ... -
TopBP1 interacts with BLM to maintain genome stability but is dispensable for preventing BLM degradation.
(CELL PRESS, 2015-03-19)The Bloom syndrome helicase BLM and topoisomerase-IIβ-binding protein 1 (TopBP1) are key regulators of genome stability. It was recently proposed that BLM phosphorylation on Ser338 mediates its interaction with TopBP1, to ... -
Direct involvement of retinoblastoma family proteins in DNA repair by non-homologous end-joining.
(CELL PRESS, 2015-03-31)Deficiencies in DNA double-strand break (DSB) repair lead to genetic instability, a recognized cause of cancer initiation and evolution. We report that the retinoblastoma tumor suppressor protein (RB1) is required for DNA ... -
Loss of INPP4B causes a DNA repair defect through loss of BRCA1, ATM and ATR and can be targeted with PARP inhibitor treatment.
(IMPACT JOURNALS LLC, 2015-04-30)Treatment options for ovarian cancer patients remain limited and overall survival is less than 50% despite recent clinical advances. The lipid phosphatase inositol polyphosphate 4-phosphatase type II (INPP4B) has been ... -
Prospective, longitudinal, multi-modal functional imaging for radical chemo-IMRT treatment of locally advanced head and neck cancer: the INSIGHT study.
(BIOMED CENTRAL LTD, 2015-05-15)BACKGROUND: Radical chemo-radiotherapy (CRT) is an effective organ-sparing treatment option for patients with locally advanced head and neck cancer (LAHNC). Despite advances in treatment for LAHNC, a significant minority ... -
Pten Regulates Epithelial Cytodifferentiation during Prostate Development.
(PUBLIC LIBRARY SCIENCE, 2015-06-15)Gene expression and functional studies have indicated that the molecular programmes involved in prostate development are also active in prostate cancer. PTEN has been implicated in human prostate cancer and is frequently ... -
Removal of H2A.Z by INO80 promotes homologous recombination.
(WILEY, 2015-08-01)The mammalian INO80 remodelling complex facilitates homologous recombination (HR), but the mechanism by which it does this is unclear. Budding yeast INO80 can remove H2A.Z/H2B dimers from chromatin and replace them with ... -
Do traditional risk stratification models for cerebrovascular events apply in irradiated head and neck cancer patients?
(ELSEVIER SCI LTD, 2015-09-01)BACKGROUND: Primary radical radiotherapy (RT) for head and neck cancer (HNC) often results in significant radiation dose to the carotid arteries. AIM: We assessed whether HNC patients are at increased risk of a cerebrovascular ... -
Efficient Genotyping of KRAS Mutant Non-Small Cell Lung Cancer Using a Multiplexed Droplet Digital PCR Approach.
(PUBLIC LIBRARY SCIENCE, 2015-09-28)Droplet digital PCR (ddPCR) can be used to detect low frequency mutations in oncogene-driven lung cancer. The range of KRAS point mutations observed in NSCLC necessitates a multiplex approach to efficient mutation detection ... -
