| Source name |
human breast cancer cell MCF-7
|
| Organism |
Homo sapiens |
| Characteristics |
morphology type: epithelial type of breast cancer cell
chip antibody/selection: sWGA Agarose beads
|
| Treatment protocol |
MCF-7 and MCF-7/ADR cells were cultured in RPMI-1640 medium with 10% fetal calf serum. MCF-7/ADR cells were cultured in the presence of a low concentration of Dox (1 µg/ml) and passaged for 1 week in drug-free medium before the experiments. For labeling, media was aspirated and the cells were washed with PBS. DMSO stocks of GalNAz was added to achieve the final treatment conditions and incubated for 48 h, with vehicle-only controls always included. ~2x107 S2 cells were used as a unit of cells for each experiment.

| Extraction protocol |
MCF-7 and MCF-7/ADR cells were maintained in RPMI-1640 medium with 10% fetal calf serum. Approximately 2 x 10e7 cells were used for each COGC-seq or sWGA-seq assay. O-GlcNAz chromatin DNAs enriched by Streptavidin-magnetic beads were purified with the Qiagen PCR purification kit. For sWGA-seq, O-GlcNAc protein bound chromatin DNAs were enriched by sWGA-agarose beads. For RNA-seq, total RNA was extracted from the MCF-7 and MCF-7/ADR cells using Trizol reagent (Invitrogen). RNA quality was checked by Agilent 2100 Bioanalyzer (Agilent Technologies, USA). RNA libraries were prepared for sequencing using standard BGI protocols.
DNA-end repair, 3'-dA overhang and ligation of methylated sequencing adaptor. PCR amplification and size selection (usually 100-300bp, including adaptor sequence. Qualified library for sequencing. RNA-seq libraries were constructed using SMARTer cDNA library construction kit (Clontech, Takara Bio, CA, USA).
