MetabolomicsOxidative phosphorylation is a metabolic vulnerability of endocrine therapy and palbociclib resistant metastatic breast cancers
Resistance to endocrine treatments and CDK4/6 inhibitors is considered a near-inevitability in most patients with estrogen receptor positive breast cancers (ER + BC). By genomic and metabolomics analyses of patients' tumours, metastasis-derived patient-derived xenografts (PDX) and isogenic cell line...

ProteomicsCoordinate Enhancer Reprogramming by GATA3 and AP1 Promotes Phenotypic Plasticity to Achieve Breast Cancer Endocrine Resistance
Phenotypic plasticity has emerged as an important mechanism of therapy resistance in cancers, yet the underlying molecular mechanisms remain unclear. Using an established breast cancer cellular model for endocrine resistance, we show that hormone resistance is associated with enhanced phenotypic pla...

GenomicsGenome-wide reprogramming of the chromatin landscape underlies endocrine therapy resistance in breast cancer
The estrogen receptor alpha (ERa) drives the growth of two-thirds of all breast cancers. Endocrine therapy impinges on estrogen-induced ERa activation to block tumor growth. However, half of ERa-positive breast cancers are tolerant or acquire endocrine therapy resistance. Here we demonstrate that br...

TranscriptomicsGene expression profiles of PDX models with acquired resistance to endocrine treatments
Acquired resistance to endocrine therapy occurs with high frequency in patients with luminal breast cancer (LBC). We report here the establishment of four patient-derived xenograft models of LBC with acquired resistance in vivo to tamoxifen and estrogen deprivation. CEL files represent expresison da...

MetabolomicsPlant elicitor peptide signalling confers rice resistance to piercing-sucking insect herbivores and pathogens
Rice is a staple food crop worldwide, and its production is severely threatened by phloem-feeding insect herbivores, particularly the brown planthopper (BPH, Nilaparvata lugens), and destructive pathogens. Despite the identification of many BPH resistance genes, the molecular basis of rice resistanc...

MetabolomicsSerum Metabolomic Profiling Reveals Load-Specific Adaptations to Resistance Training
This study deposits the untargeted ¹H-NMR serum metabolomics dataset of a parallel-group, longitudinal resistance training intervention designed to identify load-specific and training-status-specific metabolomic signatures in healthy young men. Seventeen healthy young men (age 24 ± 3 yr; height 173 ...

TranscriptomicsRNA sequencing of endocrine resistant breast cancer
*** This submission includes RNA data, with DNA files available under a different accession number*** Purpose: Endocrine therapy resistance remains the greatest challenge for treating hormone receptor positive breast cancer patients. We aim to identify molecular mechanisms underlying endocrine ther...

TranscriptomicsEstrogen deprivation alters epigenetic modifications in breast cancer cells - HOXC10 loss in endocrine resistance
Postmenopausal breast cancer patients benefit from aromatase inhibitors (AIs) that reduce the levels of estrogens critical for the growth of estrogen receptor (ER)-positive tumors. Unfortunately, many tumors are resistant to AI, and we are only beginning to understand the complex mechanisms underly...

TranscriptomicsSRC1 gene regulation in endocrine resistant breast cancer cells
The development of breast cancer resistance to endocrine therapy results from an increase in cellular plasticity leading to the development of a steroid independent tumour. The p160 steroid coactivator protein SRC-1, through interactions with developmental proteins and other non-steroidal transcrip...

TranscriptomicsExpression profile of the endocrine therapy resistant breast cancer cells LTED depleted of PBX1 or treated with the gamma-secretase inhibitor MRK003
Analysis of the response to PBX1 deprivation either using an siRNA approach or using a chemicalcompound indirectly targeting it. Deprivation of PBX1 is hypothesized to be essential for the growth of endocrine therapy resistant breast cancer cells (LTED) Total RNA was obtained from cells treated with...
