Sample GSM2772424 Query DataSets for GSM2772424
Status Public on Nov 07, 2017
Title Lrp6 Ctl rep3
Sample type SRA
 
Source name Osteoblasts
Organism Mus musculus
Characteristics genotype: Lrp6fl/fl
age: 5-6 days
tissue: Calverial osteoblasts
treatment: hydroxytamoxifen (TMX)
experimental batch: 4
Treatment protocol Osteoblasts (OBs) were isolated from calvaria of neonates (5-6 days old) by serial digestion in Collagenase 1 and EDTA solutions. These cells were cultured in DMEM/F12 supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin at 37 °C. Following 24h incubation the media was changed to remove digestion debris and non-viable cells and these cultures were treated with 100 ng/ml recombinant Wnt3a (R&D systems, Minneapolis, MN, USA). The RNA was isolated from these cultures after incubating the cells for another 24h. To generate Lrp6 and dual Lrp5/6 deficient OBs, mice carrying Lrp5 (Lrp5fl/fl) and Lrp6 (Lrp6fl/fl) conditional alleles were crossed to a tamoxifen inducible-ubiquitous Cre recombinase transgenic strain of mice (UBC-Cre-ERT2; Jackson Laboratories, Bar Harbor, ME, USA) to generate Lrp6fl/fl;UBC-Cre-ERT2 and Lrp5fl/fl;Lrp6fl/fl;UBC-Cre-ERT2 mice . Following isolation of osteoblasts from Lrp6fl/fl; UBC-Cre-ERT2 and Lrp5fl/fl;Lrp6fl/fl;UBC-Cre-ERT2, cells were cultured for 24h in DMEM+FBS+P/S media, followed by 48h treatment with DMEM+FBS+P/S with 1 uM hydroxytamoxifen (Sigma-Aldrich, St. Louis, MO, USA) prior to 24h Wnt3a treatment.
Extracted molecule total RNA
Extraction protocol Total RNA was purified using RNeasy Mini Kit (QIAGEN Inc, Germantown, MD, USA) according to manufacturer’s protocol.
Poly(A)+-enriched cDNA libraries were generated using the Illumina TruSeq Sample Preparation kit (Illumina Inc, Hayward, CA, USA) according to manufacturer’s protocol.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model NextSeq 550
 
Data processing Sequenced reads were trimmed for low-quality sequence, then mapped to mouse genome mm10 using TopHat (version 2.0.11)
After read mapping, ‘featureCounts’ from Rsubread package (version 1.22.2) was used to generate gene-wise read counts.
Genes were filtered from downstream analysis if they did not have a CPM (counts per million mapped fragments) value of at least 2 in at least five libraries
Data was normalized using edgeR and experimental batch effects were removed using 'removeBatchEffect' function in edgeR
Genome_build: mm10
Supplementary_files_format_and_content: tab-delimited text files include log2 CPM values for each Sample .
