RNA polymerase I, bending the rules?
(WILEY, 2017-09-15)Transcription initiation is one of the key regulatory steps in expressing the genetic information encoded in the DNA. Mechanisms of RNA Pol II transcription have been extensively studied, whereas the structural basis of ... -
RNA sequencing-based single sample predictors of molecular subtype and risk of recurrence for clinical assessment of early-stage breast cancer.
(NATURE PORTFOLIO, 2022-08-16)Multigene assays for molecular subtypes and biomarkers can aid management of early invasive breast cancer. Using RNA-sequencing we aimed to develop single-sample predictor (SSP) models for clinical markers, subtypes, and ... -
RNAi screen reveals synthetic lethality between cyclin G-associated kinase and FBXW7 by inducing aberrant mitoses.
(NATURE PUBLISHING GROUP, 2017-09-26)BACKGROUND: F-box and WD40 repeat domain-containing 7 (FBXW7) is an E3 ubiquitin ligase involved in the ubiquitination and degradation of multiple oncogenic substrates. The tumour suppressor function is frequently lost in ... -
RNAi screens for Rho GTPase regulators of cell shape and YAP/TAZ localisation in triple negative breast cancer.
(NATURE PUBLISHING GROUP, 2017-03-01)In order to metastasise, triple negative breast cancer (TNBC) must make dynamic changes in cell shape. The shape of all eukaryotic cells is regulated by Rho Guanine Nucleotide Exchange Factors (RhoGEFs), which activate ... -
Road Map to Safe and Well-Designed De-escalation Trials of Systemic Adjuvant Therapy for Solid Tumors.
(AMER SOC CLINICAL ONCOLOGY, 2020-12-01)An important challenge in the field of cancer is finding the balance between delivering effective treatments and avoiding adverse effects and financial toxicity caused by innovative, yet expensive, drugs. To address this, ... -
Robotic Distal Pancreatectomy Yields Superior Outcomes Compared to Laparoscopic Technique: A Single Surgeon Experience of 123 Consecutive Cases.
(MDPI, 2023-11-20)Technical limitations of laparoscopic distal pancreatectomy (LDP), in comparison to robotic distal pancreatectomy (RDP), may translate to high conversion rates and morbidity. LDP and RDP procedures performed between December ... -
Robotic versus freehand CT-guided radiofrequency ablation of pulmonary metastases: a comparative cohort study.
(SPRINGER HEIDELBERG, 2023-04-18)PURPOSE: Radiofrequency ablation (RFA) is a curative treatment option for small lung metastases, which conventionally involves multiple freehand manipulations until the treating electrode is satisfactorily positioned. ... -
Robust deep learning optical autofocus system applied to automated multiwell plate single molecule localization microscopy.
(WILEY, 2021-06-04)We presenta robust, long-range optical autofocus system for microscopy utilizing machine learning. This can be useful for experiments with long image data acquisition times that may be impacted by defocusing resulting from ... -
Robust RNA-based in situ mutation detection delineates colorectal cancer subclonal evolution.
(NATURE PUBLISHING GROUP, 2017-12-08)Intra-tumor heterogeneity (ITH) is a major underlying cause of therapy resistance and disease recurrence, and is a read-out of tumor growth. Current genetic ITH analysis methods do not preserve spatial context and may not ... -
Robustness of differential gene expression analysis of RNA-seq.
(ELSEVIER, 2021-01-01)RNA-sequencing (RNA-seq) is a relatively new technology that lacks standardisation. RNA-seq can be used for Differential Gene Expression (DGE) analysis, however, no consensus exists as to which methodology ensures robust ... -
A Role for COX20 in Tolerance to Oxidative Stress and Programmed Cell Death in Saccharomyces cerevisiae.
(MDPI, 2019-11-18)Industrial production of bioethanol from lignocellulosic materials (LCM's) is reliant on a microorganism being tolerant to the stresses inherent to fermentation. Previous work has highlighted the importance of a cytochrome ... -
Role for the Histone Demethylase KDM4B in Rhabdomyosarcoma via CDK6 and CCNA2: Compensation by KDM4A and Apoptotic Response of Targeting Both KDM4B and KDM4A.
(MDPI, 2021-04-06)Histone demethylases are epigenetic modulators that play key roles in regulating gene expression related to many critical cellular functions and are emerging as promising therapeutic targets in a number of tumor types. We ... -
The role of APOBEC3B in lung tumor evolution and targeted cancer therapy resistance.
(NATURE PORTFOLIO, 2024-01-01)In this study, the impact of the apolipoprotein B mRNA-editing catalytic subunit-like (APOBEC) enzyme APOBEC3B (A3B) on epidermal growth factor receptor (EGFR)-driven lung cancer was assessed. A3B expression in EGFR mutant ... -
The role of cancer-associated fibroblasts in altering signal transduction and drug resistance in KRAS mutated cancers
(Institute of Cancer Research (University Of London), 2023-01-04)KRAS is commonly mutated in solid tumours but effective treatment is limited due to resistance. Cancer-associated fibroblasts (CAFs) are a key tumour microenvironment component but how it interacts with KRAS mutant-cancer ... -
The role of the radiation therapy breast boost in the 2020s.
(CHURCHILL LIVINGSTONE, 2023-03-17)Given that most local relapses of breast cancer occur proximal to the original location of the primary, the delivery of additional radiation dose to breast tissue that contained the original primary cancer (known as a ... -
Role of the Tripartite Motif Protein 27 in Cancer Development
(OXFORD UNIV PRESS INC, 2012-06-01)Background The tripartite motif family protein 27 (TRIM27) is a transcriptional repressor that interacts with, and attenuates senescence induction by, the retinoblastoma-associated protein (RB1). High expression of TRIM27 ... -
Roles of cancer associated fibroblasts in squamous cell carcinoma
(Institute of Cancer Research (University Of London), 2021-03-31)Cancer associated fibroblasts (CAFs) play a key role in the tumour microenvironment (TME) of squamous cell carcinoma. Influenced by cues from cancer cells, CAFS remodel the extracellular matrix and secrete cytokines and ... -
Roles of Elongator Dependent tRNA Modification Pathways in Neurodegeneration and Cancer.
(MDPI, 2018-12-28)Transfer RNA (tRNA) is subject to a multitude of posttranscriptional modifications which can profoundly impact its functionality as the essential adaptor molecule in messenger RNA (mRNA) translation. Therefore, dynamic ... -
RORγt+ Innate Lymphoid Cells Promote Lymph Node Metastasis of Breast Cancers.
