Quantitative proteomics on wt-MCF7 versus their LTED derivatives using dimethyl labelling

ABSTRACT: Wild type (wt) MCF7 cells, modelling breast cancer at primary diagnosis, were cultured in phenol red-free RPMI supplemented with 10% FBS and 1nM estradiol (E2). Long-term oestrogen deprived (LTED) cell lines, which model resistance to endocrine therapy, were cultured in phenol red-free RPMI in the absence of exogenous E2 and supplemented with 10% dextran charcoal-stripped bovine serum (DCC). Samples were harvested at baseline and at the point of resistance (LTED). To reveal differential protein abundances between wt-MCF7 and MCF7 LTED, the peptides were labelled with chemical labelling and underwent fractionation using OFFGEL electrophoresis.

ER-RIME in wt-MCF7 and MCF7-LTED

Project description:Wild type (wt) MCF7 cells, modelling breast cancer at primary diagnosis, were cultured in phenol red-free RPMI supplemented with 10% FBS and 1nM estradiol (E2). Long-term oestrogen deprived (LTED) cell lines, which model resistance to endocrine therapy, were cultured in phenol red-free RPMI in the absence of exogenous E2 and supplemented with 10% dextran charcoal-stripped bovine serum (DCC). Samples were harvested at baseline and at the point of resistance (LTED). In order to do comparative analysis in the ER-interactome of wt-MCF7 and MCF7-LTED cells, ER-RIME (rapid immunoprecipitation mass spectrometry of endogenous proteins) was conducted in these cells.

Preclinical and clinical studies of estrogen deprivation support the PDGF/Abl pathway as a novel therapeutic target for overcoming endocrine resistance in breast cancer

Project description:The human oestrogen-positive breast cancer cell line MCF7 was cultured in phenol red-free RPMI medium supplemented with 10% fetal bovine serum, 10mg/ml insulin and 1nM estradiol (E2) and was referred to as wild-type MCF7. The wt-MCF7 cells were passaged weekly and medium was replenished every two to three days. To model acquisition of resistance to long term estrogen deprivation (LTED) on an aromatase inhibitor (AI), wt-MCF7 cells were cultured in phenol red-free RPMI medium supplemented with 10% dextran charcoal-stripped bovine serum (DCC) and 10mg/ml insulin. RNA was extracted from the LTED monolayers using RNeasy columns (Qiagen) according to manufacturerﾒs protocol. RNA amplification, labeling and hybridization on HumanWG-6 v3 Expression BeadChips were performed according to the manufacturer's instructions (http://www.illumina.com) to assess changes in gene expression during adaptation to LTED.

Elacestrant demonstrates strong anti-estrogenic activity in PDX models of estrogen receptor positive endocrine-resistant and fulvestrant-resistant breast cancer

Project description:Human breast cancer cell lines were cultured in phenol red-free RPMI1640 medium supplemented with 10% fetal bovine serum and 1nM E2. All cell lines were banked in multiple aliquots to reduce the risk of phenotypic drift and identity confirmed using STR. Cells were routinely screened for mycoplasma contamination. Long-term E deprived (LTED) cells modelling resistance to an AI were derived from all parental cell lines as previously described. Two models of MCF7-LTED cells were available: one harbouring a Y537C mutation in ESR1 and the other with wt-ESR1. SUM44-LTED was shown to harbour a natural heterozygous ESR1Y537S mutation. Elacestrant resistant cell lines were generated by growing parental cells (MCF7-LTEDY537C) long-term in the presence of RPMI1640 containing 10% DCC + 0.1nM E2 + 1μM elacestrant. All cell lines were stripped of steroids for 48-72 hours prior to the start of experiments.

Resistance to Palbociclib requires multiple targetable mechanisms highlighting the potential of drug holidays and drug switching to improve therapeutic outcome

Project description:Estrogen receptor positive (ER+) breast cancer is the most common type of breast cancer. Despite the great efficacy of endocrine therapies, resistance remains a problem. Therefore, there is an immediate need for new, effective therapies in ER+ BC. In this study, we have explored the role of a potent CDK4/6 inhibitor called palbociclib. In order to identify alterations in protein abundance between the responsive and resistant setting, we generated a panel of palbociclib-sensitive and resistant cell lines and did quantitative, shotgun proteomics using dimethyl labelling. Palbociclib sensitive cell lines (wt-MCF7 or MCF7-LTED) were cultured in phenol red-free RPMI supplemented with 10% FBS and 1nM estradiol or 10% dextran-coated charcoal (DCC) respectively. Thereafter, palbociclib resistant cell lines were generated using 1μΜ palbociclib concentration. Samples were harvested at baseline and at the point of resistance.

TUMOUR KINOME RE-WIRING GOVERNS RESISTANCE TO PALBOCICLIB IN OESTROGEN RECEPTOR POSITIVE BREAST CANCERS, HIGHLIGHTING NEW THERAPEUTIC MODALITIES

Project description:Estrogen receptor positive (ER+) breast cancers are the most common type of breast cancer. Despite the great efficacy of endocrine therapies, resistance remains a problem. Therefore, there is an immediate need for new, effective therapies in ER+ BC. In this study, we have explored the role of a potent CDK4/6 inhibitor called palbociclib. In order to identify differential phosphoproteomic events that underpin the mode of action and recurrence for this treatment, we generated a panel of palbociclib-sensitive and resistant cell lines and did quantitative, shotgun phosphoproteomics using titanium IMAC. Palbociclib sensitive cell lines (wt-MCF7 or MCF7-LTED) were cultured in phenol red-free RPMI supplemented with 10% FBS and 1nM estradiol or 10% dextran-coated charcoal (DCC) respectively. Thereafter, palbociclib resistant cell lines were generated using 1μΜ palbociclib concentration. Samples were harvested at baseline and at the point of resistance.

Expression data from MCF7 and LTED cells treated with YC-1

Project description:To identify novel therapeutic opportunities for patients with acquired resistance to endocrine treatments in breast cancer, we applied high-throughput screening to explore currently marketed drugs. The Ec50 values were determined for MCF7 and LTED cell lines to identify the compounds showing higher inhibition of LTED cells. The best compound was YC-1 and gene microarray studies were done in vitro for mechanistic exploration. MCF7 and LTED cells were treated with YC-1 for RNA extraction and hybridization on Affymetrix microarrays.

Genome-wide reprogramming of the chromatin landscape underlies endocrine therapy resistance in breast cancer

Project description: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 breast cancer cells undergo genome-wide reprogramming of their chromatin landscape, defined by epigenomic maps and chromatin openness, as they acquire resistance to endocrine therapy. This reveals a role for the Notch pathway while excluding classical ERa signaling. In agreement, blocking Notch signaling, using gamma-secretase inhibitors, or targeting its downstream gene PBX1 abrogates growth of endocrine therapy-resistant breast cancer cells. Moreover Notch signaling through PBX1 directs a transcriptional program predictive of tumor outcome and endocrine therapy response. Comparing histone modifications (H3K4me2 and H3K36me3), chromatin openness (FAIRE) and PBX1 binding between endocrine therapy sensitive MCF7 and resistant MCF7-LTED cells.

Breast cancer cells resistant to hormone deprivation maintain an estrogen receptor alpha-dependent, E2F-directed transcriptional program

Project description:A significant fraction of breast cancers exhibit de novo or acquired resistance to estrogen deprivation. To model resistance to aromatase inhibitor (AI) therapy, long-term estrogen-deprived (LTED) derivatives of MCF-7 and HCC-1428 cells were generated through culture for 3 and 7 months under hormone-depleted conditions, respectively. These LTED cells showed sensitivity to the ER downregulator fulvestrant under hormone-depleted conditions, suggesting continued dependence upon ER signaling for hormone-independent growth. To evaluate the role of ER in hormone-independent growth, LTED cells were treated +/- 1 uM fulvestrant x 48 h before RNA was harvested for gene expression analysis. MCF-7/LTED and HCC-1428/LTED cells were treated with 10% DCC-FBS with or without the estrogen receptor antagonist drug fulvestrant for 48 hrs prior to RNA harvest for array analysis. Three replicates per condition.
