Genome-wide characterization reveals complex interplay between TP53 and TP63 in response to genotoxic stress.
(OXFORD UNIV PRESS, 2014-01-01)In response to genotoxic stress the TP53 tumour suppressor activates target gene expression to induce cell cycle arrest or apoptosis depending on the extent of DNA damage. These canonical activities can be repressed by ... -
Genomic and Transcriptomic Determinants of Therapy Resistance and Immune Landscape Evolution during Anti-EGFR Treatment in Colorectal Cancer.
(CELL PRESS, 2019-06-26)Despite biomarker stratification, the anti-EGFR antibody cetuximab is only effective against a subgroup of colorectal cancers (CRCs). This genomic and transcriptomic analysis of the cetuximab resistance landscape in 35 RAS ... -
Genomic and transcriptomic heterogeneity in metaplastic carcinomas of the breast.
(NATURE PUBLISHING GROUP, 2017-12-01)Metaplastic breast cancer (MBC) is a rare special histologic type of triple-negative breast cancer, characterized by the presence of neoplastic cells showing differentiation towards squamous epithelium and/or mesenchymal ... -
Genomic Classification and Clinical Outcome in Rhabdomyosarcoma: A Report From an International Consortium.
(LIPPINCOTT WILLIAMS & WILKINS, 2021-09-10)PURPOSE: Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood. Despite aggressive therapy, the 5-year survival rate for patients with metastatic or recurrent disease remains poor, and beyond PAX-FOXO1 fusion ... -
Genomic Classification and Prognosis in Acute Myeloid Leukemia.
(MASSACHUSETTS MEDICAL SOC, 2016-06-09)BACKGROUND: Recent studies have provided a detailed census of genes that are mutated in acute myeloid leukemia (AML). Our next challenge is to understand how this genetic diversity defines the pathophysiology of AML and ... -
Genomic evolution and chemoresistance in germ-cell tumours.
(NATURE PUBLISHING GROUP, 2016-11-30)Germ-cell tumours (GCTs) are derived from germ cells and occur most frequently in the testes. GCTs are histologically heterogeneous and distinctly curable with chemotherapy. Gains of chromosome arm 12p and aneuploidy are ... -
Genomic Instability and TP53 Genomic Alterations Associate With Poor Antiproliferative Response and Intrinsic Resistance to Aromatase Inhibitor Treatment.
(AMER SOC CLINICAL ONCOLOGY, 2019-01)PURPOSE: Although aromatase inhibitor (AI) treatment is effective in estrogen receptor-positive postmenopausal breast cancer, resistance is common and incompletely explained. Genomic instability, as measured by somatic ... -
Genomic landscape and clonal architecture of mouse oral squamous cell carcinomas dictate tumour ecology.
(NATURE PORTFOLIO, 2020-11-09)To establish whether 4-nitroquinoline N-oxide-induced carcinogenesis mirrors the heterogeneity of human oral squamous cell carcinoma (OSCC), we have performed genomic analysis of mouse tongue lesions. The mutational ... -
Genomic landscape of platinum resistant and sensitive testicular cancers.
(NATURE PUBLISHING GROUP, 2020-05-04)While most testicular germ cell tumours (TGCTs) exhibit exquisite sensitivity to platinum chemotherapy, ~10% are platinum resistant. To gain insight into the underlying mechanisms, we undertake whole exome sequencing and ... -
Genomic profile of advanced breast cancer in circulating tumour DNA.
(NATURE PORTFOLIO, 2021-04-23)The genomics of advanced breast cancer (ABC) has been described through tumour tissue biopsy sequencing, although these approaches are limited by geographical and temporal heterogeneity. Here we use plasma circulating ... -
Geospatial immune variability illuminates differential evolution of lung adenocarcinoma.
(NATURE PORTFOLIO, 2020-07-01)Remarkable progress in molecular analyses has improved our understanding of the evolution of cancer cells toward immune escape1-5. However, the spatial configurations of immune and stromal cells, which may shed light on ... -
Germ line mutations in shelterin complex genes are associated with familial chronic lymphocytic leukemia.
(AMER SOC HEMATOLOGY, 2016-11-10)Chronic lymphocytic leukemia (CLL) can be familial; however, thus far no rare germ line disruptive alleles for CLL have been identified. We performed whole-exome sequencing of 66 CLL families, identifying 4 families where ... -
Germline allelic expression of genes at 17q22 locus associates with risk of breast cancer.
(ELSEVIER SCI LTD, 2022-06-27)INTRODUCTION: Translation of genome-wide association study (GWAS) findings into preventive approaches is challenged by the identification of the causal risk variants and the understanding of the biological mechanisms by ... -
Germline variants at SOHLH2 influence multiple myeloma risk.
(SPRINGERNATURE, 2021-04-19)Multiple myeloma (MM) is caused by the uncontrolled, clonal expansion of plasma cells. While there is epidemiological evidence for inherited susceptibility, the molecular basis remains incompletely understood. We report a ... -
Glycogen synthase kinase 3 controls migration of the neural crest lineage in mouse and Xenopus.
(NATURE PUBLISHING GROUP, 2018-03-19)Neural crest migration is critical to its physiological function. Mechanisms controlling mammalian neural crest migration are comparatively unknown, due to difficulties accessing this cell population in vivo. Here we report ... -
Guidelines for Acquisition, Interpretation, and Reporting of Whole-Body MRI in Myeloma: Myeloma Response Assessment and Diagnosis System (MY-RADS).
(RADIOLOGICAL SOC NORTH AMERICA, 2019-04-01)Acknowledging the increasingly important role of whole-body MRI for directing patient care in myeloma, a multidisciplinary, international, and expert panel of radiologists, medical physicists, and hematologists with specific ... -
Heterocellular gene signatures reveal luminal-A breast cancer heterogeneity and differential therapeutic responses.
(NATURE PUBLISHING GROUP, 2019-08-02)Breast cancer is a highly heterogeneous disease. Although differences between intrinsic breast cancer subtypes have been well studied, heterogeneity within each subtype, especially luminal-A cancers, requires further ... -
Heterogeneity in global gene expression profiles between biopsy specimens taken peri-surgically from primary ER-positive breast carcinomas.
(BIOMED CENTRAL LTD, 2016-04-01)BACKGROUND: Gene expression is widely used for the characterisation of breast cancers. Variability due to tissue heterogeneity or measurement error or systematic change due to peri-surgical procedures can affect measurements ... -
