Sample GSM2650077 Query DataSets for GSM2650077
Status Public on Jun 21, 2017
Title 189_outerCC
Sample type SRA
 
Source name cumulus cells
Organism Bos taurus
Characteristics cell type: cumulus cells
Extracted molecule total RNA
Extraction protocol We extracted RNA from cumulus cells using the guanidinium thiocyanate-phenol chloroform procedure (Trizol reagent, Thermofisher), with the addition of 0.5ul GlycoBlue Coprecipitant (Thermofisher) as a RNA carrier. For the oocytes, we added 2l of the lysis buffer (20 IU/l RNase inhibitor (Amresco), 0.2% Triton X-100 (Amresco)) to the tube.
We eluted the RNA from CCs in 4ml of a solution containing dNTPs and oligo-dT30VN and proceeded with the polyA+ whole transcriptome amplification with the Smart-seq2 protocol for cDNA amplification. For the oocytes, we added 2l of the lysis buffer (20 IU/l RNase inhibitor (Amresco), 0.2% Triton X-100 (Amresco)) to the tube and proceeded with the polyA+ whole transcriptome amplification with the Smart-seq2 protocol for cDNA amplification. The samples were subjected to 16 cycles of PCR amplification. For all samples, we used one ng of amplified cDNA for library preparation using the Nextera XT DNA library preg Kit (Illumina, Inc), as and followed the procedures described in the Smart-seq2 protocol.

Description RNA
Data processing The libraries were aligned against the Bos taurus genome UMD3.1 downloaded from Ensembl using the STAR (v2.5.2) aligner. Only reads with a unique match to the genome and less than five mismatches were further filtered to eliminate duplicates with picard (v2.5, http://broadinstitute.github.io/picard/).
The bam files containing non-duplicated reads were used as input for Cufflinks (v.2.2.1) together with Ensembl gene annotation UMD3.1.87 to obtain fragments per kilogram per million reads (FPKM) data. Genes were subjected to analytical procedures if FPKM>0.5 in eight or more cells of each group (oocytes, innerCC, outerCC).
The non-duplicated reads were submited to counting according to the Ensembl gene annotation UMD3.1.87 using HTSeq (v. 0.6.1) software.
Genome_build: UMD3.1
