Investigating acute cellular responses to elevated APOBEC3B expression
(Institute of Cancer Research (University Of London), 2021-09-30)The cytosine deaminase APOBEC3B (A3B) functions as part of innate immunity by mutating viral DNA and preventing replication. Large-scale genome sequencing studies and examination of expression levels have identified mutations ... -
Investigating Apoptozole as a Chemical Probe for HSP70 Inhibition.
(2015-01)The use of chemical tools to validate clinical targets has gained in popularity over recent years and the importance of understanding the activity, selectivity and mechanism of action of these compounds is well recognized. ... -
Investigating intracranial tumour growth patterns with multiparametric MRI incorporating Gd-DTPA and USPIO-enhanced imaging.
(2016-11)High grade and metastatic brain tumours exhibit considerable spatial variations in proliferation, angiogenesis, invasion, necrosis and oedema. Vascular heterogeneity arising from vascular co-option in regions of invasive ... -
Investigating Low-Velocity Fluid Flow in Tumors with Convection-MRI.
(2018-04)Several distinct fluid flow phenomena occur in solid tumors, including intravascular blood flow and interstitial convection. Interstitial fluid pressure is often raised in solid tumors, which can limit drug delivery. To ... -
Investigating roles of the SWI/SNF complex subunits in genome stability, chromatin organisation, innate immune signalling and replication stress
(Institute of Cancer Research (University Of London), 2021-12-31)The alterations of the SWI/SNF chromatin remodelling complex subunits happen in 30% of malignancies. The exact mechanisms by which SWI/SNF alterations contribute to tumourigenesis are still not entirely clear. Here, I ... -
Investigating the Contribution of Collagen to the Tumor Biomechanical Phenotype with Noninvasive Magnetic Resonance Elastography.
(2019-11)Increased stiffness in the extracellular matrix (ECM) contributes to tumor progression and metastasis. Therefore, stromal modulating therapies and accompanying biomarkers are being developed to target ECM stiffness. Magnetic ... -
Investigating the effect of a magnetic field on dose distributions at phantom-air interfaces using PRESAGE® 3D dosimeter and Monte Carlo simulations.
(2018-02-26)Dosimetric quality assurance (QA) of the new Elekta Unity (MR-linac) will differ from the QA performed of a conventional linac due to the constant magnetic field, which creates an electron return effect (ERE). In this work ... -
Investigating the efficacy of osimertinib and crizotinib in phase 3 clinical trials on anti-cancer treatment-induced cardiotoxicity: are real-world studies the way forward?
(SAGE PUBLICATIONS LTD, 2022-02-15)BACKGROUND.: Oncology clinical trials demonstrate the risk of cardiotoxicity but are not sufficient to reveal the true risk. In this article, we compared the incidence of cardiotoxicity of crizotinib and osimertinib from ... -
Investigating the heterogeneity of alkylating agents' efficacy and toxicity between sexes: A systematic review and meta-analysis of randomized trials comparing cyclophosphamide and ifosfamide (MAIAGE study).
(2017-08)Background A marginal interaction between sex and the type of alkylating agent was observed for event-free survival in the Euro-EWING99-R1 randomized controlled trial (RCT) comparing cyclophosphamide and ifosfamide in Ewing ... -
Investigating the mehcanisms of drug resistance in gastro-intestinal cancers
(Institute of Cancer Research (University Of London), 2020-03-31)Despite many effective therapies for gastro-intestinal (GI) cancers, both primary and acquired mechanisms of resistance commonly occur. The subclonal complexity of intra-tumoural heterogeneity in these cancers further ... -
Investigating the molecular mechanisms of fraction size sensitivity in irradiated cells
(Institute of Cancer Research (University Of London), 2020-09-30)Fractionated radiotherapy is used clinically when it spares healthy tissue relative to the cancer; the healthy tissue is described as more fraction size sensitive. However, a molecular understanding of the mechanisms that ... -
Investigating the phosphinic acid tripeptide mimetic DG013A as a tool compound inhibitor of the M1-aminopeptidase ERAP1.
ERAP1 is a zinc-dependent M1-aminopeptidase that trims lipophilic amino acids from the N-terminus of peptides. Owing to its importance in the processing of antigens and regulation of the adaptive immune response, dysregulation ... -
Investigating the possible causal role of coffee consumption with prostate cancer risk and progression using Mendelian randomization analysis.
(2017-01)Coffee consumption has been shown in some studies to be associated with lower risk of prostate cancer. However, it is unclear if this association is causal or due to confounding or reverse causality. We conducted a Mendelian ... -
Investigating the role of DTX3L in the replication stress response
(Institute of Cancer Research (University Of London), 2023-01-20)DNA replication must be carried out with high fidelity to ensure accurate transfer of genetic information upon cell division. The mechanisms by which damage upon DNA is repaired are extensive and are increasingly well ... -
Investigating the Vascular Phenotype of Subcutaneously and Orthotopically Propagated PC3 Prostate Cancer Xenografts Using Combined Carbogen Ultrasmall Superparamagnetic Iron Oxide MRI.
(2016-10)The aim of this study was to use the combined carbogen-ultrasmall superparamagnetic iron oxide (CUSPIO) magnetic resonance imaging (MRI) method, which uses spatial correlations in independent susceptibility imaging biomarkers, ... -
Investigation of combination treatments using radiotherapy and stimulators of nucleic-acid sensing immune pathways in an organoid model of basal-like breast cancer
(Institute of Cancer Research (University Of London), 2022-10-12)The majority of triple-negative breast cancers (TNBC) are of the basal-like subtype, which has a poorer prognosis than non-basal TNBC. Few targeted therapies are approved for TNBC, and although immune checkpoint inhibitors ... -
Investigation of In Vivo skin stiffness anisotropy in breast cancer related lymphoedema.
(2016-01)There is a limited range of suitable measurement techniques for detecting and assessing breast cancer related lymphoedema (BCRL). This study investigated the suitability of using skin stiffness measurements, with a particular ... -
Investigation of scintillator coated CCDs for medical imaging
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2006-02)We describe the development of a scintillator-coated charge coupled device (CCD) based camera for imaging small volumes of radionuclide uptake in tissues. The high-resolution gamma imager (HRGI) is a collimated, ...
