Genome-wide maps of CtBP binding profile in breast cancer cell line MCF-7

Project description:CtBP is a global co-repressor by serving as transcriptional factor in multiple pathways. CtBP functioned as transcriptional factor by recruiting other cofactors such as G9a, HDAC1 and PcG proteins. CtBP is found to be over enriched in several type of tumor samples. To dipict the role of CtBP in globally regulating gene expression, we applied ChIP-seq technology to find out the binding profile of CtBP in breast cancer cell line MCF-7. Our data suggest CtBP plays a global regulatory role in DNA damage repair, tumor initiation, and EMT process. Examine CtBP binding in MCF-7 cells

Genome-wide mapping of HIST1H2ac binding sites in MCF-7 cells

Project description:Previously, we have shown that HIST1H2ac is overexpressed in MCF-7 breast cancer cell line. It acts as a master regulator of estrogen receptor alpha-dependent gene expression in ER+ breast cancer cells. In the present study, we investigate the genome-wide protein DNA-binding events of HIST1H2ac protein in MCF-7 breast cancer cell line by over-expressing hemagglutinin (HA)-tagged HIST1H2ac and compared with MCF-7 cells over-expressing HA. The protein-bound DNA was recovered by immunoprecipitation using anti-HA antibody. The ChIP DNA and input DNA were sequenced with an Illumina HiSeq 2000 sequencer.

Untargeted metabolomics of breast cell lines in the presence or the absence of CtBP inhibitors

Project description:Experiments to test the effect of CtBP2 inhibition on metabolism of breast cell lines. In particular, experiment 1 involves comparison between a normal breast cell line (MCF102A) and a triple-negative breast cancer cell line (MDA-MB231). Experiment 2 is a study between MDA-MB231 silenced for CtBP2 by stable RNA interference (shCtBP2 cells) compared to scramble (shCTRL cells). Experiment 3 is a comparison between a normal breast cell line (MCF102A) and a triple-negative breast cancer cell line (MDA-MB231)in the presence of the absence of small-molecule CtBP inhibitors: HIPP (400 μM) or P4 (300 μM)for 48 hours.

RNA Sequencing of two Breast Cancer Cell Lines in Comparison to Healthy Epithelial Breast Cells

Project description:We studied genes, that are differentially expressed between malignant and normal breast tissue, to find weak spots for anti-cancer therapy development. RNA sequencing of three cell lines was performed: MCF-7 (epithelial breast cancer cell line), BCC (primary breast tumour cell line) and MCF-10A (epithelial breast cell line).

One-pot comparative analysis and characterization of MCF-7 and MCF-10A cell lines

Project description:A comparison of different energetics based techniques for the characterization of two mammalian breast cell lines, MCF-7 a luminal A breast cancer cell line and MCF-10A a normal human breast cell line. The techniques of stability of proteins from rates of oxidation (SPROX), thermal proteome profiling (TPP), and conventional expression level analyses were compared and the relative advantages and disadvantages are discussed.

Histone methyltransferase SMYD3 knockdown effects in MCF7 breast cancer cell line

Project description:The study aims to elucidate the effect of histone methyltransferase SMYD3 on gene expression in MCF-7 breast cancer cell line. Knockdown luciferase control v.s. knockdown SMYD3 in MCF-7 breast cancer cell line were conducted. Results identify a large proportion of cell cycle-related genes regulated by SMYD3.

CTCF_ER_Arrays

Project description:CCCTC-binding factor (CTCF) is a conserved zinc finger transcription factor involved in chromatin looping. Recent evidence has shown a role for CTCF in ER biology. This experiment maps CTCF binding genome-wide in breast cancer cells and shows that CTCF binding does not change with estrogen or tamoxifen treatment. We find a small but reproducible proportion of CTCF binding events that overlap with both the nuclear receptor estrogen receptor and the forkhead protein FoxA1. These overlapping binding events are likely to be functional as they are biased towards estrogen-regulated genes. In addition, we identify cell-line specific CTCF binding events. These cell-line specific CTCF binding events are more likely to be associated with cell-line specific ER vinding events and are also more likely to be adjacent to genes that are expressed in that particular cell line. These data suggest a positive, pro-transcriptional role for CTCF in ER-mediated gene expression in breast cancer cells.
