Sample GSM4709334 Query DataSets for GSM4709334
Status Public on Aug 31, 2020
Title WT rep2
Sample type SRA
Source name Tooth germ
Organism Mus musculus
Characteristics strain: C57BL/6
genotype: wild type
tissue: Tooth germ
age: post natal day 7
Treatment protocol n/a
Growth protocol n/a
Extracted molecule total RNA
Extraction protocol To construct each cDNA library, total RNA in P7 first molars from littermate WT and Gpr115-KO mice was extracted using TRIzol reagent (Invitrogen).
cDNA libraries were produced using a Nextera XT library kit (Illumina), and samples were run on a HiSeq1500 (Illumina) configured for 150 x 150 pair-end reads.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 1500
Description total RNA
Data processing Basecalls performed using Illumina’s RTA 2.0.12
Sequenced reads were mapped to GRCm38.vM11 mouse genome using STAR v2.5.2a in  single-pass mode. With the following parameters:  --outFilterIntronMotifs RemoveNoncanonicalUnannotated --outSAMstrandField None --outFilterType BySJout --outFilterMultimapNmax 20 --outFilterMatchNminOverLread 0.25 --outFilterScoreMinOverLread 0.25 --alignSJoverhangMin 8 --alignSJDBoverhangMin 1 --outFilterMismatchNmax 999 --outFilterMismatchNoverLmax 0.3 --alignIntronMin 20 --alignIntronMax 1000000 --alignMatesGapMax 1000000 --outSAMtype BAM SortedByCoordinate --bamRemoveDuplicatesType UniqueIdentical --quantMode GeneCounts
Gene counts were generated with STAR v2.5.2a built-in counting option --quantMode GeneCounts against a customized Gencode GRCm38 vM11 genome annotation GTF which included ERCCs.
A expression matrix was assembled using R. Genes with less than 5 reads in at least one of the samples were filtered out before differential gene expression analysis.
Differential expression was performed using the DESeq2, EdgeR and Limma-Voom R packages.
Genome_build: Custom mm10/GRCm38.vM11+ERCCs
Supplementary_files_format_and_content: Tab delimited files include a raw counts and TMM-normalized expression matrices.
