Heterogeneity in global gene expression profiles between biopsy specimens taken peri-surgically from primary ER-positive breast carcinomas.
López-Knowles, E; Gao, Q; Cheang, MCU; Morden, J; Parker, J; et al. (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 ... -
Impact of aromatase inhibitor treatment on global gene expression and its association with antiproliferative response in ER+ breast cancer in postmenopausal patients.
Gao, Q; López-Knowles, E; Cheang, MCU; Morden, J; Ribas, R; et al. (BMC, 2019-12-31)BACKGROUND: Endocrine therapy reduces breast cancer mortality by 40%, but resistance remains a major clinical problem. In this study, we sought to investigate the impact of aromatase inhibitor (AI) therapy on gene expression ... -
Impact of mutational profiles on response of primary oestrogen receptor-positive breast cancers to oestrogen deprivation.
Gellert, P; Segal, CV; Gao, Q; López-Knowles, E; Martin, L-A; et al. (NATURE PORTFOLIO, 2016-11-09)Pre-surgical studies allow study of the relationship between mutations and response of oestrogen receptor-positive (ER+) breast cancer to aromatase inhibitors (AIs) but have been limited to small biopsies. Here in phase I ... -
Impairment of a distinct cancer-associated fibroblast population limits tumour growth and metastasis.
Jungwirth, U; van Weverwijk, A; Evans, RJ; Jenkins, L; Vicente, D; et al. (NATURE PORTFOLIO, 2021-06-10)Profiling studies have revealed considerable phenotypic heterogeneity in cancer-associated fibroblasts (CAFs) present within the tumour microenvironment, however, functional characterisation of different CAF subsets is ... -
Major Impact of Sampling Methodology on Gene Expression in Estrogen Receptor-Positive Breast Cancer.
Gao, Q; López-Knowles, E; U Cheang, MC; Morden, J; Ribas, R; et al. (OXFORD UNIV PRESS, 2018-05-22)To investigate the impact of sampling methodology on gene expression data from primary estrogen receptor-positive (ER+) breast cancer biopsies, global gene expression was measured in core-cut biopsies at baseline and surgery ... -
Molecular changes in premenopausal oestrogen receptor-positive primary breast cancer in Vietnamese women after oophorectomy.
Haynes, BP; Ginsburg, O; Gao, Q; Folkerd, E; Afentakis, M; et al. (NATURE PUBLISHING GROUP, 2017-11-27)For premenopausal women with primary ER + breast cancer, oophorectomy (OvX) is an evidence-based cost-effective option and is standard treatment in many countries. However, there is virtually no data describing the effects ... -
Novel 18-gene signature for predicting relapse in ER-positive, HER2-negative breast cancer.
Buus, R; Yeo, B; Brentnall, AR; Klintman, M; Cheang, MCU; et al. (2018-09-04)Background Several prognostic signatures for early oestrogen receptor-positive (ER+) breast cancer have been established with a 10-year follow-up. We tested the hypothesis that signatures optimised for 0-5-year and 5-10-year ... -
