Somatic PIK3CA Mutations in Sporadic Cerebral Cavernous Malformations.
(MASSACHUSETTS MEDICAL SOC, 2021-09-09)
BACKGROUND: Cerebral cavernous malformations (CCMs) are common sporadic and inherited vascular malformations of the central nervous system. Although familial CCMs are linked to loss-of-function mutations in KRIT1 (CCM1), ...
PPM1D mutations are oncogenic drivers of de novo diffuse midline glioma formation.
(NATURE PORTFOLIO, 2022-02-01)
The role of PPM1D mutations in de novo gliomagenesis has not been systematically explored. Here we analyze whole genome sequences of 170 pediatric high-grade gliomas and find that truncating mutations in PPM1D that increase ...
Ultra-Sensitive Mutation Detection and Genome-Wide DNA Copy Number Reconstruction by Error-Corrected Circulating Tumor DNA Sequencing.
(OXFORD UNIV PRESS INC, 2018-08-27)
BACKGROUND: Circulating free DNA sequencing (cfDNA-Seq) can portray cancer genome landscapes, but highly sensitive and specific technologies are necessary to accurately detect mutations with often low variant frequencies. ...
Abiraterone shows alternate activity in models of endocrine resistant and sensitive disease.
(SPRINGERNATURE, 2018-08-01)
BACKGROUND: Resistance to endocrine therapy remains a major clinical problem in the treatment of oestrogen-receptor positive (ER+) breast cancer. Studies show androgen-receptor (AR) remains present in 80-90% of metastatic ...
Structural variants shape driver combinations and outcomes in pediatric high-grade glioma.
(OXFORD UNIV PRESS INC, 2022-06-01)
We analyzed the contributions of structural variants (SVs) to gliomagenesis across 179 pediatric high-grade gliomas (pHGGs). The most recurrent SVs targeted MYC isoforms and receptor tyrosine kinases (RTKs), including an ...
A HUWE1 defect causes PARP inhibitor resistance by modulating the BRCA1-∆11q splice variant.
(SPRINGERNATURE, 2023-09-01)
Although PARP inhibitors (PARPi) now form part of the standard-of-care for the treatment of homologous recombination defective cancers, de novo and acquired resistance limits their overall effectiveness. Previously, ...
The mutational signatures of formalin fixation on the human genome.
(NATURE PORTFOLIO, 2022-09-06)
Clinical archives of patient material near-exclusively consist of formalin-fixed and paraffin-embedded (FFPE) blocks. The ability to precisely characterise mutational signatures from FFPE-derived DNA has tremendous ...
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 ...
Discovery of naturally occurring ESR1 mutations in breast cancer cell lines modelling endocrine resistance.
(NATURE PORTFOLIO, 2017-11-30)
Resistance to endocrine therapy remains a major clinical problem in breast cancer. Genetic studies highlight the potential role of estrogen receptor-α (ESR1) mutations, which show increased prevalence in the metastatic, ...
Molecular characterisation of aromatase inhibitor-resistant advanced breast cancer: the phenotypic effect of ESR1 mutations.
(SPRINGERNATURE, 2019-01-22)
BACKGROUND: Several thousand breast cancer patients develop resistance to aromatase inhibitors (AIs) each year in the UK. Rational treatment requires an improved molecular characterisation of resistant disease. MATERIALS ...
