Next Generation Sequencing Facilitates Quantitative Analysis of human breast cancer cell T47D and T47D-TR Transcriptomes

Project description:To gain new insight into the resistance to hormonal therapy in breast cancer, we generated a tamoxifen-resistant human breast cancer cell line T47D-TR by exposing estrogen-sensitive cell line T47D to increasing concentrations of 4-hydroxy tamoxifen (4-OHT) and identified its resistance with different ways. What we interested is the underlying mechanisms of breast cancer tamoxifen resistance which was not reported yet.Here, we detect the RNA sequence of both the two cell lines hoping to find some evidence.

RNA-Seq of human cell lines Ishikawa, MCF7 and T47D treated with estrogen, progesterone and their antagonists

Project description:In this study the effect of estrogen (E2) and progesterone (P4) and their antagonists Tamoxifen, and Mifepristone (RU486) were assesed in endometrial epithelial cell line Ishikawa and compared to breast cancer cell lines MCF7 and T47D. Concentrations used for E2 and P4 treatments were 10 -8 M and for antagonists 10 -6 M. RNA-Sequencing (Illumina GenomeAnalyzer IIe) was applied to study global gene expression in three different cell lines. Expression values after hormonal or antagonist treatments in two different time points (3h and 12h) were compared to non-treated cells.

RNA-seq of ERINA knockdown T47D cell lines

Project description:We identified an intergenic lncRNA ERINA (estrogen inducible lncRNA) as a novel lncRNA that is associated with chemo-resistance and highly expressed in multiple cancer types, especially in estrogen receptor (ER) positive breast cancers. Functional characterizations based on RNA-seq analyses established ERINA as an oncogenic lncRNA, because knockdown of ERINA in breast cancer cells inhibits cell cycle progression and tumor cell proliferation in vitro and xenograft tumor growth in vivo.

Effect of RBP2 on MCF7 breast cancer cells (RNA-seq)

Project description:RNA-sequencing analysis of RBP2 overexpressing MCF7 cell lines. RBP2 (also known as JARID1A), a member of the JARID1 family of histone H3 lysine K4 demethylases, has been considered to have an oncogenic potential in several cancer including breast cancer. Results provide insight into the transcriptional regulation of RBP2 in estrogen receptor positve breast cancer.

ER/PR RIME Experiments in MCF7 and T47D cell lines

Project description:Immuno-precipitation followed by MS was performed using the RIME protocol in this study. Estrogen Receptor (ER) and Progestorone Receptor (PR) were targetted using antibodies. The experiments were performed in a quantitative manner using SILAC labelling. Cells grown in complete serum (estrogenic) conditions were compared against an cells in similar complete media, however supplemented with Progesterone (PG) or R5020 for 4 hours. Experiments were performed in MCF7 and T47D cell lines

RNA-Seq Analysis of Anacardic Acid Treated MCF7 and MDA-MB-231 Breast Cancer Cell Lines

Project description:Anacardic acid (AnAc) is a mixture of 6-alkylbenzoic acid congeners that are produced in a number of plants. Previously, we showed a specific congener AnAc 24:1n5 acts as a nuclear receptor alternate site modulator (NRAM) to inhibit breast cancer cells in an estrogen receptor (ER)-dependent manner by interfering with ER-DNA binding. AnAc 24:1n5 also inhibited the growth of a triple negative breast cancer (TNBC) cell line, through an undefined mechanism. Additional work from our labs indicated AnAc 24:1n5 inhibits prostaglandin synthase and that inhibition is more specific to COX-2. Reports from other investigators indicate AnAc has a number of interesting potential pharmacological targets. We previously used qRT-PCR to investigate expression changes in endogenous estrogen-regulated genes, i.e., TFF1, CCND1, and CTSD in breast cancer cell lines. However, since AnAc has the capacity of effect multiple molecular targets and since we detected an ER-independent inhibition of breast cancer cell proliferation, we suspect additional unknown molecular targets are affected in breast cancer cells. Identification of such targets using RNA-seq would be quite beneficial in targeting TNBC which primarily affects premenopausal women with a predominance in women of African and Latina ancestry. The goal of this portion of the project is to use next-generation RNA-SEQ to identify alterations in molecular target sequence levels in ER-positive and -negative breast cancer cell lines treated with AnAc.

Expression data from zinc-finger-transcription-factor-induced Fulvestrant-Resistant MCF7 Cell Lines

Project description:Multiple gene expression studies have demonstrated that breast cancer biological diversity is associated with distinct transcriptional programs. Transcription factors, because of their unique ability to coordinate the expression of multiple genes, are speculated to play a role in generating phenotypic plasticity associated with cancer progression including acquired drug resistance. Combinatorial libraries of artificial zinc-finger transcription factors (ZF-TFs) provide a robust means for inducing and understanding various functional components of the cancer phenotype. Herein, we utilized combinatorial ZF-TF library technology to better understand how breast cancer cells acquire resistance to a fulvestrant, a clinically important anti-endocrine therapeutic agent. We isolated six ZF-TF library members capable of inducing stable, long-term anti-endocrine drug-resistance in two independent estrogen receptor positive breast cancer cell lines. Comparative gene expression profile analysis of the ZF-TF-transduced breast cancer cell lines revealed a 72-gene cluster that constituted a common signature for the fulvestrant-resistance phenotype. Pathway enrichment-analysis of gene expression data revealed that the ZF-TF-induced fulvestrant resistance is associated with an estrogen receptor negative-like gene set and four unique myb-regulated gene sets. Furthermore, we identified a set of genes strongly expressed in the ZF-TF-induced fulvestrant-resistant cells that was correlated with a lower probability of distant metastasis-free or death-from-relapse-free survival of breast cancer patients.

Single-cell transcriptome analysis reveals estrogen signaling augments the mitochondrial folate pathway to coordinately fuel purine and polyamine synthesis in breast cancer cells (T47D)

Project description:Estrogen regulates diverse physiological effects and drives breast tumor progression by directly activating the estrogen receptor α (ERα). However, due to the stochastic nature of gene transcription and the resulting heterogeneous cellular responses, it is important to investigate estrogen-stimulated gene expression profiles at the single-cell level in order to fully understand how ERα regulates transcription in breast cancer cells. In this study, we performed single-cell transcriptome analysis on ERα-positive breast cancer cell lines following 17β-estradiol stimulation. We sequenced a total of 177 single-cell transcriptomes and observed robust gene expression diversity between individual cells.

Differential Gene Expression between MCF10A and MCF7 cells

Project description:These RNA-seq data were generated to correlate with genomic interaction data in a related Hi-C analysis. MCF10A is a normal-like mammary epithelial cell line and MCF7 is a transformed estrogen responsive breast cancer cell line derived from a metastatic site; both are commonly used in models of breast cancer progression. Analysis revealed a set of genes related to repression of WNT signalling that were both up-regulated in MCF7 and located in genomic regions that had transitioned from closed to open structure in MCF7. RNA-seq of MCF10A and MCF7 cells. 3 replicates each. Sequencing was strand-specific and conducted on ribo-depleted RNA.
