| Sample type |
SRA |

|
| Source name |
beast cancer cell line
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: MCF7
treatment: cells were transfected with siCTL, after 1hr treatment with 100nM E2
|
| Treatment protocol |
Before experiment, the cells were changed to deficient MEM plus 5% charcoal treated phenol red free medium to culture for 3 days, followed by treatemnt of either 100nM 17-?-estrodial or ethanol for 1hr.
|
| Growth protocol |
MCF7 obtained from ATCC were cultured in ?-MEM media supplemented with 10% FBS in a 5% CO2 humidified incubator.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
MCF7 cells were subjected to nuclear run-on for 5minutes at 30 degree with BrU labeling. The run-on RNAs were pull down by BrU beads and subjected to library preparation for deep sequencing.
We followed a previous published protocol (Ingolia et al., 2009 Science; Wang et al., 2011 Nature; Li et al., 2013 Nature). Briefly, the run-on RNA were first added with a polyA tracts by RNA polyA polymerase. This polyA tail enables the run-on RNA to be reverse transcribed into single strand cDNA by Reverse Transcriptase. The cDNA was circularized by CircLigase (Epicentre) and re-linearized by Ape1, subsequently subjected to PCR amplification and deep sequencing.

| Description |
nascent RNA
cells were transfected with siCTL, after 1hr treatment with 100nM E2, subjected to GRO-seq, serves as a control for cells with siNCAPG and 100nM E2 treatment (v.s. E2-siNCAPG_GROseq)
library strategy: GRO-seq
|
| Data processing |
Basecalls performed using CASAVA version 1.4
Gro-seq reads were aligned to the hg18 genome assembly using Bowtie version 2.0.1.
The bigwig files were generated by using Homer v3.9, which the total tags are normalized to 1.00e+07.
Genome_build: hg18
