Early Enrichment of ESR1 Mutations and the Impact on Gene Expression in Presurgical Primary Breast Cancer Treated with Aromatase Inhibitors.
(2019-12)
PURPOSE:To investigate the presence of ESR1 mutations in primary estrogen-receptor-positive (ER+) breast cancer treated with extended (>4 weeks) neoadjuvant (presurgical) aromatase inhibitor (NAI) therapy and to identify ...
GDNF-RET signaling in ER-positive breast cancers is a key determinant of response and resistance to aromatase inhibitors.
(AMER ASSOC CANCER RESEARCH, 2013-06-15)
Most breast cancers at diagnosis are estrogen receptor-positive (ER(+)) and depend on estrogen for growth and survival. Blocking estrogen biosynthesis by aromatase inhibitors has therefore become a first-line endocrine ...
Cholesterol biosynthesis pathway as a novel mechanism of resistance to estrogen deprivation in estrogen receptor-positive breast cancer.
(BMC, 2016-06-01)
BACKGROUND: Therapies targeting estrogenic stimulation in estrogen receptor-positive (ER+) breast cancer (BC) reduce mortality, but resistance remains a major clinical problem. Molecular studies have shown few high-frequency ...
Analysis of ESR1 mutation in circulating tumor DNA demonstrates evolution during therapy for metastatic breast cancer.
(AMER ASSOC ADVANCEMENT SCIENCE, 2015-11-11)
Acquired ESR1 mutations are a major mechanism of resistance to aromatase inhibitors (AIs). We developed ultra high-sensitivity multiplex digital polymerase chain reaction assays for ESR1 mutations in circulating tumor DNA ...
E-Cadherin/ROS1 Inhibitor Synthetic Lethality in Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2018-04-01)
The cell adhesion glycoprotein E-cadherin (CDH1) is commonly inactivated in breast tumors. Precision medicine approaches that exploit this characteristic are not available. Using perturbation screens in breast tumor cells ...
Capture Hi-C identifies putative target genes at 33 breast cancer risk loci.
(NATURE PUBLISHING GROUP, 2018-03-12)
Genome-wide association studies (GWAS) have identified approximately 100 breast cancer risk loci. Translating these findings into a greater understanding of the mechanisms that influence disease risk requires identification ...
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 ...
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 ...
Discovery of Selective Estrogen Receptor Covalent Antagonists for the Treatment of ERαWT and ERαMUT Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2018-09-01)
Mutations in estrogen receptor alpha (ERα) that confer resistance to existing classes of endocrine therapies are detected in up to 30% of patients who have relapsed during endocrine treatments. Because a significant ...
