Project description:We used a metabolic labeling (GalNAz) based O-GlcNAc sites identification and quantification proteomics method to compare the O-GlcNAc chromatin of MCF-7 and MCF-7/ADR cells. The O-GlcNAc chromatin-associated proteins can be metabolically labeled with azides, followed by reaction with a cleavable DADPS (dialkoxydiphenylsilane) alkyne-biotin linker and enrichment with streptavidin beads. After cleavage of DADPS by formic acid, O-GlcNAc modified peptides were quantitative analysis using tandem mass spectroscopy (MS).
Project description:O-GlcNAcylation performs a critical role in regulating stress response program and cellular homeostasis. However, systematic studies of O-GlcNAc regulated genotoxic stress-responsive transcriptional reprograming have been limited. The GalNAz metabolic labeled global chromatin-associated proteins were isolated from the cross-linked MCF-7 and MCF-7/ADR cells nucleus, and then modified by downstream click-chemistry. The de-crosslinked O-GlcNAz chromatin-bound proteins were enriched for label-free quantitative proteomics by LC-MS/MS.
Project description:By obtaining over four billion bases of sequence from chromatin immunoprecipitated DNA in MCF-7 cells with six2 overexpression or not, we generated genome-wide chromatin-state maps of these two cells. We identified the detailed binding sites of six2 in MCF-7 cells.

Project description:To identify the miRNAs that are differentially expressed and secreted between the MDA-MB-231 metastatic breast cancer cells and the MCF-10A non-cancerous human mammary epithelial cells, we profiled the cellular and exosomal small RNAs (between 17 and 52 nt) isolated from these two cell lines by Solexa deep sequencing. MiRNAs that are significantly different between the two cell lines are identified. RNA was extracted from cultured MDA-MB-231 and MCF-10A cells or purified exosomes secreted by these cells, and subjected to library construction and Solexa deep sequencing.
