An In Vivo Functional Screen Identifies JNK Signaling As a Modulator of Chemotherapeutic Response in Breast Cancer.
Ashenden, M; van Weverwijk, A; Murugaesu, N; Fearns, A; Campbell, J; et al. (AMER ASSOC CANCER RESEARCH, 2017-09-01)Chemotherapy remains the mainstay of treatment for advanced breast cancer; however, resistance is an inevitable event for the majority of patients with metastatic disease. Moreover, there is little information available ... -
Changes in expression of hormone-regulated and proliferation-associated genes across the menstrual cycle in oestrogen receptor-positive breast cancer
Haynes, BP; Ginsburg, O; Gao, Q; Folkerd, E; Afentakis, M; et al. (SPRINGER, 2020-04-01) -
Cholesterol biosynthesis pathway as a novel mechanism of resistance to estrogen deprivation in estrogen receptor-positive breast cancer.
Simigdala, N; Gao, Q; Pancholi, S; Roberg-Larsen, H; Zvelebil, M; et al. (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 ... -
Combination of mTORC1/2 inhibitor vistusertib plus fulvestrant in vitro and in vivo targets oestrogen receptor-positive endocrine-resistant breast cancer.
Pancholi, S; Leal, MF; Ribas, R; Simigdala, N; Schuster, E; et al. (BMC, 2019-12-04)BACKGROUND: Endocrine therapies are still the main strategy for the treatment of oestrogen receptor-positive (ER+) breast cancers (BC), but resistance remains problematic. Cross-talk between ER and PI3K/AKT/mTORC has been ... -
Discovery of naturally occurring ESR1 mutations in breast cancer cell lines modelling endocrine resistance.
Martin, L-A; Ribas, R; Simigdala, N; Schuster, E; Pancholi, S; et al. (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, ... -
GDNF-RET signaling in ER-positive breast cancers is a key determinant of response and resistance to aromatase inhibitors.
Morandi, A; Martin, L-A; Gao, Q; Pancholi, S; Mackay, A; et al. (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 ... -
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 ... -
Menstrual cycle associated changes in hormone-related gene expression in oestrogen receptor positive breast cancer.
Haynes, BP; Ginsburg, O; Gao, Q; Folkerd, E; Afentakis, M; et al. (NATURE PUBLISHING GROUP, 2019-11-15)The major changes in hormone levels that occur through the menstrual cycle have been postulated to affect the expression of hormone-regulated and proliferation-associated genes (PAGs) in premenopausal ER+ breast cancer. ... -
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 ... -
