Subclonal reconstruction of tumors by using machine learning and population genetics.
(NATURE PUBLISHING GROUP, 2020-09-01)Most cancer genomic data are generated from bulk samples composed of mixtures of cancer subpopulations, as well as normal cells. Subclonal reconstruction methods based on machine learning aim to separate those subpopulations ... -
The Hippo transducer YAP1 transforms activated satellite cells and is a potent effector of embryonal rhabdomyosarcoma formation.
(CELL PRESS, 2014-08-11)The role of the Hippo pathway effector YAP1 in soft tissue sarcomas is poorly defined. Here we report that YAP1 activity is elevated in human embryonal rhabdomyosarcoma (ERMS). In mice, sustained YAP1 hyperactivity in ... -
Inter-observer agreement of baseline whole body MRI in multiple myeloma.
(BMC, 2020-07-14)BACKGROUND: Whole body magnetic resonance imaging (MRI) is now incorporated into international guidance for imaging patients with multiple myeloma. The aim of this study was to investigate inter-observer agreement of triple ... -
Systematic evaluation of the prognostic impact and intratumour heterogeneity of clear cell renal cell carcinoma biomarkers.
(ELSEVIER, 2014-07-19)BACKGROUND: Candidate biomarkers have been identified for clear cell renal cell carcinoma (ccRCC) patients, but most have not been validated. OBJECTIVE: To validate published ccRCC prognostic biomarkers in an independent ... -
Sex specific retinoic acid signaling is required for the initiation of urogenital sinus bud development.
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2014-11-15)The mammalian urogenital sinus (UGS) develops in a sex specific manner, giving rise to the prostate in the male and the sinus vagina in the embryonic female. Androgens, produced by the embryonic testis, have been shown to ... -
Tumour responses following a steroid switch from prednisone to dexamethasone in castration-resistant prostate cancer patients progressing on abiraterone.
(NATURE PUBLISHING GROUP, 2014-12-09)BACKGROUND: Abiraterone is a CYP17A1 inhibitor that improves survival in castration-resistant prostate cancer (CRPC). Abiraterone is licensed in combination with prednisone 5 mg twice daily to prevent a syndrome of secondary ... -
Whole-exome sequencing reveals the mutational spectrum of testicular germ cell tumours.
(NATURE PUBLISHING GROUP, 2015-01-22)Testicular germ cell tumours (TGCTs) are the most common cancer in young men. Here we perform whole-exome sequencing (WES) of 42 TGCTs to comprehensively study the cancer's mutational profile. The mutation rate is uniformly ... -
Genetic and functional diversity of propagating cells in glioblastoma.
(CELL PRESS, 2015-01-13)Glioblastoma (GBM) is a lethal malignancy whose clinical intransigence has been linked to extensive intraclonal genetic and phenotypic diversity and the common emergence of therapeutic resistance. This interpretation ... -
Expression of the fetal hematopoiesis regulator FEV indicates leukemias of prenatal origin.
(Springer Science and Business Media LLC, 2017-05-01)The origin of cancers is associated with etiology as well as therapeutics. Several studies reveal that malignancies in children can originate in utero. However, a diagnostic approach to distinguish between cancers initiated ... -
Origins of STIL-TAL1 fusion genes in children who later developed paediatric T-cell acute lymphoblastic leukaemia: An investigation of neonatal blood spots.
(Wiley, 2018-11-01)SCL/TAL1 interrupting locus (STIL)-T-cell acute leukaemia (TAL1) fusion genes are present in approximately 11-27% of children with paediatric T-cell acute lymphoblastic leukaemia (T-ALL), but the developmental timing of ... -
Pro-inflammatory cytokines favor the emergence of ETV6-RUNX1-positive pre-leukemic cells in a model of mesenchymal niche.
(Wiley, 2020-01-01)ETV6-RUNX1 (E/R) fusion gene, arising in utero from translocation t(12;21)(p13:q22), is the most frequent alteration in childhood acute lymphoblastic leukemia (ALL). However, E/R is insufficient to cause overt leukemia ... -
Shieldin complex promotes DNA end-joining and counters homologous recombination in BRCA1-null cells.
(NATURE PUBLISHING GROUP, 2018-08-01)BRCA1 deficiencies cause breast, ovarian, prostate and other cancers, and render tumours hypersensitive to poly(ADP-ribose) polymerase (PARP) inhibitors. To understand the resistance mechanisms, we conducted whole-genome ... -
Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
(CELL PRESS, 2015-01-12)We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ... -
BRCA1 and BRCA2 tumor suppressors protect against endogenous acetaldehyde toxicity.
(WILEY, 2017-10-01)Maintenance of genome integrity requires the functional interplay between Fanconi anemia (FA) and homologous recombination (HR) repair pathways. Endogenous acetaldehyde, a product of cellular metabolism, is a potent source ... -
A Biobank of Breast Cancer Explants with Preserved Intra-tumor Heterogeneity to Screen Anticancer Compounds.
(CELL PRESS, 2016-09-22)The inter- and intra-tumor heterogeneity of breast cancer needs to be adequately captured in pre-clinical models. We have created a large collection of breast cancer patient-derived tumor xenografts (PDTXs), in which the ... -
Patient-derived tumour xenografts for breast cancer drug discovery.
(BIOSCIENTIFICA LTD, 2016-12-01)Despite remarkable advances in our understanding of the drivers of human malignancies, new targeted therapies often fail to show sufficient efficacy in clinical trials. Indeed, the cost of bringing a new agent to market ... -
Capture Hi-C identifies the chromatin interactome of colorectal cancer risk loci.
(NATURE PORTFOLIO, 2015-02-19)Multiple regulatory elements distant from their targets on the linear genome can influence the expression of a single gene through chromatin looping. Chromosome conformation capture implemented in Hi-C allows for genome-wide ... -
Intra-tumor genetic heterogeneity and alternative driver genetic alterations in breast cancers with heterogeneous HER2 gene amplification.
(BMC, 2015-05-22)BACKGROUND: HER2 is overexpressed and amplified in approximately 15% of invasive breast cancers, and is the molecular target and predictive marker of response to anti-HER2 agents. In a subset of these cases, heterogeneous ... -
Androgen receptor expression in circulating tumour cells from castration-resistant prostate cancer patients treated with novel endocrine agents.
(NATURE PUBLISHING GROUP, 2015-03-31)BACKGROUND: Abiraterone and enzalutamide are novel endocrine treatments that abrogate androgen receptor (AR) signalling in castration-resistant prostate cancer (CRPC). Here, we developed a circulating tumour cells (CTCs)-based ...
