Sample GSM2159811 Query DataSets for GSM2159811
Status Public on Aug 11, 2017
Title MCF-7 cell line Anti-miR-29a transfected replicate 2
Sample type SRA
Source name MCF-7 cell line Anti-miR-29a transfected
Organism Homo sapiens
Characteristics cell line: MCF-7
transfection: Anti-miR-29a
Treatment protocol Cells were transfected with anti-miR-29a (Anti-miRTMs, Ambion), pre-miR-29a and pre-miR-29b-1 (Pre-miRTMs, Ambion), using Lipofectamine RNAiMAX (Invitrogen) for 48 h.
Growth protocol MCF-7 and LCC9 cells were grown in triplicates in phenol red IMEM supplemented with 5% dextran-coated charcoal-stripped fetal bovine serum (FBS) and 1% penicillin/streptomycin (P/S).
Extracted molecule total RNA
Extraction protocol RNA was isolated using the Exiqon miRCURYTM RNA Isolation kit and its concentration and quality assessed using a NanoDrop spectrophotometer. Quantitative real-time PCR confirmed overexpression of miR-29b-1, miR-29a, or knockdown of miR-29b-1 and miR-29a in respective samples.
The Truseq Stranded mRNA kit was used to prepare mRNA libraries from 2ug total RNA. Libraries were confirmed on the Agilent 2100 Bioanalyzer and quantitated using the Illumina Library Quantification Kit, ABI Prism qPCR Mix from Kapa Biosystems and the ABI7900HT real-time PCR instrument. 75-76 cycle single read sequencing was performed with the 500 High-output v2 (75 cycle) sequencing kit on the Illumina NextSeq500 instrument.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
Description MCF-7_2B
Data processing Illumina FASTQ Generation version 1.0.0 used for basecalling
Quality control (QC) of the raw sequence data was performed using FastQC. The FastQC results indicated that all sequences were of high quality.
Sequences were directly aligned to the Homo sapiens reference genome assembly hs_ref_GRCh37 downloaded from NCBI. The annotation file Homo_sapiens.GRCh37.73.gtf Downloaded from Ensembl August 26, 2015 was used with all records annotated as mitochondrial or ribosomal RNA removed.
The analysis was performed using The Illumina Basesapce RNA-Seq Alignment App version 1.0.0 with Tophat2 and Bowtie2, generating alignment files in bam format.
Differentially expressed genes (DEGS) were identified using Cuffdiff (v2.2.1).
