(ELSEVIER IRELAND LTD, 2020-11-01)INTRODUCTION: Dose escalation to dominant intraprostatic lesions (DILs) is a novel method to increase the therapeutic ratio in localised prostate cancer. The Stereotactic Prostate Augmented Radiotherapy with Cyberknife ... -
Strategies and technical challenges for imaging oligometastatic disease: Recommendations from the European Organisation for Research and Treatment of Cancer imaging group.
(ELSEVIER SCI LTD, 2018-03-01)Patients with oligometastatic disease (OMD) often have controllable symptoms, and cures are possible. Technical improvements in surgery and radiotherapy have introduced the option of metastasis-directed ablative therapies ... -
Streamlining Detection of Fusion Genes in Colorectal Cancer: Having "Faith" in Precision Oncology in the (Tissue) "Agnostic" Era.
(AMER ASSOC CANCER RESEARCH, 2019-03-15)The FDA recently granted tissue-agnostic approval for the first-in-class TRK inhibitor larotrectinib for patients whose tumors harbor fusions in neurotrophic receptor tyrosine kinases. These fusion genes have a frequency ... -
Stringent and reproducible tetracycline-regulated transgene expression by site-specific insertion at chromosomal loci with pre-characterised induction characteristics
(2007-01-01)Background: The ability to regulate transgene expression has many applications, mostly concerning the analysis of gene function. Desirable induction characteristics, such as low un-induced expression, high induced expression ... -
Stromal cell ratio based on automated image analysis as a predictor for platinum-resistant recurrent ovarian cancer.
(BMC, 2019-02-18)BACKGROUND: Identifying high-risk patients for platinum resistance is critical for improving clinical management of ovarian cancer. We aimed to use automated image analysis of hematoxylin & eosin (H&E) stained sections to ... -
Structural Aberrations with Secondary Implications (SASIs): consensus recommendations for reporting of cancer susceptibility genes identified during analysis of Copy Number Variants (CNVs).
(BMJ PUBLISHING GROUP, 2019-11-01)Clinical testing with chromosomal microarray (CMA) is most commonly undertaken for clinical indications such as intellectual disability, dysmorphic features and/or congenital abnormalities. Identification of a structural ... -
Structural and functional characterisation of human RNA helicase DHX8 provides insights into the mechanism of RNA-stimulated ADP release.
(PORTLAND PRESS LTD, 2019-09-13)DHX8 is a crucial DEAH-box RNA helicase involved in splicing and required for the release of mature mRNA from the spliceosome. Here, we report the biochemical characterisation of full-length human DHX8 and the catalytically ... -
Structural and functional characterization of a DARPin which inhibits Ras nucleotide exchange.
(NATURE PUBLISHING GROUP, 2017-07-14)Ras mutations are the oncogenic drivers of many human cancers and yet there are still no approved Ras-targeted cancer therapies. Inhibition of Ras nucleotide exchange is a promising new approach but better understanding ... -
Structural and functional characterization of the human and yeast TFIIIC complex
(Institute of Cancer Research (University Of London), 2019-11-30)TFIIIC is one of the conserved transcription factors required for RNA Polymerase (Pol) III transcription, which transcribes DNA into untranslated RNAs, such as tRNAs. However, TFIIIC's mechanistic role in Pol III regulation ... -
Structural Basis for Auto-Inhibition of the NDR1 Kinase Domain by an Atypically Long Activation Segment.
(CELL PRESS, 2018-08-07)The human NDR family kinases control diverse aspects of cell growth, and are regulated through phosphorylation and association with scaffolds such as MOB1. Here, we report the crystal structure of the human NDR1 kinase ... -
Structural basis for the inactivation of cytosolic DNA sensing by the vaccinia virus.
(NATURE PORTFOLIO, 2022-11-18)Detection of cytosolic DNA is a central element of the innate immunity system against viral infection. The Ku heterodimer, a component of the NHEJ pathway of DNA repair in the nucleus, functions as DNA sensor that detects ... -
