Recommendations for Multicentre Clinical Trials Involving Dosimetry for Molecular Radiotherapy.
(ELSEVIER SCIENCE LONDON, 2021-02-01)Multicentre clinical trials involving a dosimetry component are becoming more prevalent in molecular radiotherapy and are essential to generate the evidence to support individualised approaches to treatment planning and ... -
Recommendations for vaccination in multiple myeloma: a consensus of the European Myeloma Network.
(SPRINGERNATURE, 2020-08-19)Vaccination is one of the most successful medical interventions that has saved the life of millions of people. Vaccination is particularly important in patients with multiple myeloma, who have an increased risk of infections ... -
Reconstitution of the destruction complex defines roles of AXIN polymers and APC in β-catenin capture, phosphorylation, and ubiquitylation.
(CELL PRESS, 2021-08-19)The Wnt/β-catenin pathway is a highly conserved, frequently mutated developmental and cancer pathway. Its output is defined mainly by β-catenin's phosphorylation- and ubiquitylation-dependent proteasomal degradation, ... -
Reconstructing cancer evolution at the single-cell level in patient-derived organoids
(Institute of Cancer Research (University Of London), 2024-01-30)Genetic mutations in cancer driver genes are heritable and can confer aggressive and therapy-resistant properties to cells. However genetic driver events do not fully explain the malignant phenotype, and it is becoming ... -
Reconstructing single-cell karyotype alterations in colorectal cancer identifies punctuated and gradual diversification patterns.
(NATURE PORTFOLIO, 2021-08-01)Central to tumor evolution is the generation of genetic diversity. However, the extent and patterns by which de novo karyotype alterations emerge and propagate within human tumors are not well understood, especially at ... -
Recovery of Salivary Function: Contralateral Parotid-sparing Intensity-modulated Radiotherapy versus Bilateral Superficial Lobe Parotid-sparing Intensity-modulated Radiotherapy.
(ELSEVIER SCIENCE LONDON, 2016-09-01)AIMS: To establish whether there is a difference in recovery of salivary function with bilateral superficial lobe parotid-sparing intensity-modulated radiotherapy (BSLPS-IMRT) versus contralateral parotid-sparing IMRT ... -
Recurrent FOSL1 rearrangements in desmoplastic fibroblastoma.
(WILEY, 2023-02-01)The FOS gene family has been implicated in tumourigenesis across several tumour types, particularly mesenchymal tumours. The rare fibrous tumour desmoplastic fibroblastoma is characterised by overexpression of FOSL1. ... -
Recurrent inactivation of STAG2 in bladder cancer is not associated with aneuploidy.
(NATURE PUBLISHING GROUP, 2013-12-01)Urothelial bladder cancer (UBC) is heterogeneous at the clinical, pathological and genetic levels. Tumor invasiveness (T) and grade (G) are the main factors associated with outcome and determine patient management. A ... -
Recurrent KRAS Codon 146 mutations in human colorectal cancer
(2006-08)Recurrent KRAS Codon 146 mutations in human colorectal cancer An activating point mutation in codon 12 of the HRAS gene was the first somatic point mutation identified in a human cancer and established the role of somatic ... -
Recurrent MET fusion genes represent a drug target in pediatric glioblastoma.
(NATURE PUBLISHING GROUP, 2016-11-01)Pediatric glioblastoma is one of the most common and most deadly brain tumors in childhood. Using an integrative genetic analysis of 53 pediatric glioblastomas and five in vitro model systems, we identified previously ... -
Redox requirements for ubiquitin-like urmylation of Ahp1, a 2-Cys peroxiredoxin from yeast.
(ELSEVIER, 2020-02-01)The yeast peroxiredoxin Ahp1, like related anti-oxidant enzymes in other species, undergoes urmylation, a lysine-directed conjugation to ubiquitin-like modifier Urm1. Ahp1 assembles into a homodimer that detoxifies peroxides ... -
Redox Signaling by the RNA Polymerase III TFIIB-Related Factor Brf2.
(CELL PRESS, 2015-12-03)TFIIB-related factor 2 (Brf2) is a member of the family of TFIIB-like core transcription factors. Brf2 recruits RNA polymerase (Pol) III to type III gene-external promoters, including the U6 spliceosomal RNA and selenocysteine ... -
Reduced Dose Posterior to Prostate Correlates With Increased PSA Progression in Voxel-Based Analysis of 3 Randomized Phase 3 Trials.
(ELSEVIER SCIENCE INC, 2020-12-01)PURPOSE: Reducing margins during treatment planning to decrease dose to healthy organs surrounding the prostate can risk inadequate treatment of subclinical disease. This study aimed to investigate whether lack of dose to ... -
Reduced genomic tumor heterogeneity after neoadjuvant chemotherapy is related to favorable outcome in patients with esophageal adenocarcinoma.
(2016-07)Neoadjuvant chemo(radio)therapy followed by surgery is the standard of care for patients with locally advanced resectable esophageal adenocarcinoma (EAC). There is increasing evidence that drug resistance might be related ... -
