Circulating Tumour DNA Sequencing Identifies a Genetic Resistance-Gap in Colorectal Cancers with Acquired Resistance to EGFR-Antibodies and Chemotherapy.
(MDPI, 2020-12-11)Epidermal growth factor receptor antibodies (EGFR-Abs) confer a survival benefit in patients with RAS wild-type metastatic colorectal cancer (mCRC), but resistance invariably occurs. Previous data showed that only a minority ... -
Circulating tumour DNA sequencing to determine therapeutic response and identify tumour heterogeneity in patients with paediatric solid tumours.
(ELSEVIER SCI LTD, 2021-12-18)OBJECTIVE: Clinical diagnostic sequencing of circulating tumour DNA (ctDNA) is well advanced for adult patients, but application to paediatric cancer patients lags behind. METHODS: To address this, we have developed a ... -
Circulating Tumour DNAs and Non-Coding RNAs as Liquid Biopsies for the Management of Colorectal Cancer Patients
(MDPI, 2020-09-01)<jats:p>Circulating tumour DNAs and non-coding RNAs present in body fluids have been under investigation as tools for cancer diagnosis, disease monitoring, and prognosis for many years. These so-called liquid biopsies offer ... -
Circulating vitamin D and breast cancer risk: an international pooling project of 17 cohorts.
(SPRINGER, 2023-01-01)Laboratory and animal research support a protective role for vitamin D in breast carcinogenesis, but epidemiologic studies have been inconclusive. To examine comprehensively the relationship of circulating 25-hydroxyvitamin ... -
Circulating Vitamin D and Colorectal Cancer Risk: An International Pooling Project of 17 Cohorts.
(OXFORD UNIV PRESS INC, 2019-02-01)BACKGROUND: Experimental and epidemiological studies suggest a protective role for vitamin D in colorectal carcinogenesis, but evidence is inconclusive. Circulating 25-hydroxyvitamin D (25(OH)D) concentrations that minimize ... -
Circulating vitamin D concentration and risk of seven cancers: Mendelian randomisation study.
(BMJ PUBLISHING GROUP, 2017-10-31)Objective To determine if circulating concentrations of vitamin D are causally associated with risk of cancer.Design Mendelian randomisation study.Setting Large genetic epidemiology networks (the Genetic Associations and ... -
Circulating vitamin D concentrations and risk of breast and prostate cancer: a Mendelian randomization study.
(OXFORD UNIV PRESS, 2019-10-01)BACKGROUND: Observational studies have suggested an association between circulating vitamin D concentrations [25(OH)D] and risk of breast and prostate cancer, which was not supported by a recent Mendelian randomization ... -
Cisplatin Substitution with Carboplatin During Radical Chemoradiotherapy for Oesophagogastric Carcinoma: Outcomes from a Tertiary Centre.
(2018-10)Background/aim Cisplatin-based radical chemoradiotherapy (CRT) is utilised in oesophagogastric (OG) cancer but the toxicity profile of cisplatin limits its use. This study aimed to evaluate the clinical characteristics and ... -
Citrobacter rodentium induces rapid and unique metabolic and inflammatory responses in mice suffering from severe disease.
(WILEY-HINDAWI, 2020-01-01)The mouse pathogen Citrobacter rodentium is used to model infections with enterohaemorrhagic and enteropathogenic Escherichia coli (EHEC and EPEC). Pathogenesis is commonly modelled in mice developing mild disease (e.g., ... -
Citrobacter rodentium Subverts ATP Flux and Cholesterol Homeostasis in Intestinal Epithelial Cells In Vivo.
(CELL PRESS, 2017-11-07)The intestinal epithelial cells (IECs) that line the gut form a robust line of defense against ingested pathogens. We investigated the impact of infection with the enteric pathogen Citrobacter rodentium on mouse IEC ... -
Class II phosphoinositide 3-kinase C2β regulates a novel signaling pathway involved in breast cancer progression.
(IMPACT JOURNALS LLC, 2016-04-05)It is now well established that the enzymes phosphoinositide 3-kinases (PI3Ks) have a key role in the development and progression of many cancer types and indeed PI3Ks inhibitors are currently being tested in clinical ... -
Class(y) Dissection of BRAF Heterogeneity: Beyond Non-V600.
(AMER ASSOC CANCER RESEARCH, 2019-12-01)Different classes of BRAF mutations are present in colorectal and other cancers. Non-V600 mutations are rare; however, their detection rate will increase as the use of next-generation sequencing ramps up quickly in clinical ... -
Classification of fibroglandular tissue distribution in the breast based on radiotherapy planning CT.
(BIOMED CENTRAL LTD, 2016-01-14)BACKGROUND: Accurate segmentation of breast tissues is required for a number of applications such as model based deformable registration in breast radiotherapy. The accuracy of breast tissue segmentation is affected by the ... -
Classifying the evolutionary and ecological features of neoplasms.
(NATURE PUBLISHING GROUP, 2017-10-01)Neoplasms change over time through a process of cell-level evolution, driven by genetic and epigenetic alterations. However, the ecology of the microenvironment of a neoplastic cell determines which changes provide adaptive ... -
Claudin-18 expression in oesophagogastric adenocarcinomas: a tissue microarray study of 523 molecularly profiled cases.
(NATURE PUBLISHING GROUP, 2019-07-30)BACKGROUND: Claudin-18 (CLDN18) is a highly specific tight junction protein of the gastric mucosa. An isoform of CLDN18, the Claudin 18.2, has recently emerged as an innovative drug target for metastatic gastric cancer. ... -
