Sample GSM1115996 Query DataSets for GSM1115996
Status Public on Jun 04, 2013
Title GROSeq_E2_repeat2
Sample type SRA
 
Source name MCF7
Organism Homo sapiens
Characteristics cell line: MCF7
treatment: 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-β-estrodial or ethanol for 1hr.
Growth protocol MCF7 obtained from ATCC were cultured in α-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). 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.
