Magnitude of observer error using cone beam CT for prostate interfraction motion estimation: effect of reducing scan length or increasing exposure.
(BRITISH INST RADIOLOGY, 2015-10-01)OBJECTIVE: Cone beam CT (CBCT) enables soft-tissue registration to planning CT for position verification in radiotherapy. The aim of this study was to determine the interobserver error (IOE) in prostate position verification ... -
Nine-year Follow-up for a Study of Diffusion-weighted Magnetic Resonance Imaging in a Prospective Prostate Cancer Active Surveillance Cohort.
(ELSEVIER SCIENCE BV, 2016-06-01)BACKGROUND: In active surveillance (AS) for prostate cancer there are few data on long-term outcomes associated with novel imaging markers. OBJECTIVE: To determine long-term outcomes with respect to the apparent diffusion ... -
Prospective Study Delivering Simultaneous Integrated High-dose Tumor Boost (≤70 Gy) With Image Guided Adaptive Radiation Therapy for Radical Treatment of Localized Muscle-Invasive Bladder Cancer.
(ELSEVIER SCIENCE INC, 2016-04-01)PURPOSE: Image guided adaptive radiation therapy offers individualized solutions to improve target coverage and reduce normal tissue irradiation, allowing the opportunity to increase the radiation tumor dose and spare ... -
Volumetry of the dominant intraprostatic tumour lesion: intersequence and interobserver differences on multiparametric MRI.
(BRITISH INST RADIOLOGY, 2017-03-01)OBJECTIVE: To establish the interobserver reproducibility of tumour volumetry on individual multiparametric (mp) prostate MRI sequences, validate measurements with histology and determine whether functional to morphological ... -
The Heterocellular Emergence of Colorectal Cancer.
(2017-02)Tissues contain multiple different cell types and can be considered to be heterocellular systems. Signaling between different cells allows tissues to achieve phenotypes that no cell type can achieve in isolation. Such ... -
Whole-body diffusion-weighted MR imaging for assessment of treatment response in myeloma.
(RADIOLOGICAL SOC NORTH AMERICA, 2014-06-01)PURPOSE: To determine the feasibility of whole-body diffusion-weighted (DW) magnetic resonance (MR) imaging for assessment of treatment response in myeloma. MATERIALS AND METHODS: This prospective single-institution study ... -
TGFβ-mediated suppression of CD248 in non-cancer cells via canonical Smad-dependent signaling pathways is uncoupled in cancer cells.
(2014-02-20)Background CD248 is a cell surface glycoprotein, highly expressed by stromal cells and fibroblasts of tumors and inflammatory lesions, but virtually undetectable in healthy adult tissues. CD248 promotes tumorigenesis, while ... -
Tumour cell-derived Wnt7a recruits and activates fibroblasts to promote tumour aggressiveness.
(NATURE PUBLISHING GROUP, 2016-01-18)Stromal fibroblast recruitment to tumours and activation to a cancer-associated fibroblast (CAF) phenotype has been implicated in promoting primary tumour growth and progression to metastatic disease. However, the mechanisms ... -
Cdc42EP3/BORG2 and Septin Network Enables Mechano-transduction and the Emergence of Cancer-Associated Fibroblasts.
(CELL PRESS, 2015-12-29)Cancer-associated fibroblasts (CAFs) are non-cancerous cells found in solid tumors that remodel the tumor matrix and promote cancer invasion and angiogenesis. Here, we demonstrate that Cdc42EP3/BORG2 is required for the ... -
Mesenchymal Cancer Cell-Stroma Crosstalk Promotes Niche Activation, Epithelial Reversion, and Metastatic Colonization.
(2015-12-06)During metastatic colonization, tumor cells must establish a favorable microenvironment or niche that will sustain their growth. However, both the temporal and molecular details of this process remain poorly understood. ... -
Plasma Metabolomic Changes following PI3K Inhibition as Pharmacodynamic Biomarkers: Preclinical Discovery to Phase I Trial Evaluation.
(AMER ASSOC CANCER RESEARCH, 2016-06-01)PI3K plays a key role in cellular metabolism and cancer. Using a mass spectrometry-based metabolomics platform, we discovered that plasma concentrations of 26 metabolites, including amino acids, acylcarnitines, and ... -
Proteomics profiling of interactome dynamics by colocalisation analysis (COLA).
(ROYAL SOC CHEMISTRY, 2016-12-20)Localisation and protein function are intimately linked in eukaryotes, as proteins are localised to specific compartments where they come into proximity of other functionally relevant proteins. Significant co-localisation ... -
The Borg family of Cdc42 effector proteins Cdc42EP1-5.
(PORTLAND PRESS LTD, 2016-12-15)Despite being discovered more than 15 years ago, the Borg (binder of Rho GTPases) family of Cdc42 effector proteins (Cdc42EP1-5) remains largely uncharacterised and relatively little is known about their structure, regulation ... -
Complications of hyperglycaemia with PI3K-AKT-mTOR inhibitors in patients with advanced solid tumours on Phase I clinical trials.
(NATURE PUBLISHING GROUP, 2015-12-01)BACKGROUND: PI3K-AKT-mTOR inhibitors (PAMi) are promising anticancer treatments. Hyperglycaemia is a mechanism-based toxicity of these agents and is becoming increasingly important with their use in larger numbers of ... -
Reproducible automated phosphopeptide enrichment using magnetic TiO2 and Ti-IMAC.
(AMER CHEMICAL SOC, 2014-09-18)Reproducible, comprehensive phosphopeptide enrichment is essential for studying phosphorylation-regulated processes. Here, we describe the application of hyper-porous magnetic TiO2 and Ti-IMAC microspheres for uniform ... -
Vessel co-option mediates resistance to anti-angiogenic therapy in liver metastases.
(NATURE PUBLISHING GROUP, 2016-11-01)The efficacy of angiogenesis inhibitors in cancer is limited by resistance mechanisms that are poorly understood. Notably, instead of through the induction of angiogenesis, tumor vascularization can occur through the ... -
The PROFILE Feasibility Study: Targeted Screening of Men With a Family History of Prostate Cancer.
(WILEY, 2016-06-01)BACKGROUND: A better assessment of individualized prostate cancer (PrCa) risk is needed to improve screening. The use of the prostate-specific antigen (PSA) level for screening in the general population has limitations and ... -
Imaging biomarker roadmap for cancer studies.
