Annotation data on gene length and G+C content from NCBI

Description

Annotation data for human genes defined by Entrez identifiers and downloaded on 22/02/2012.

Usage

data(annotEntrez220212)

Format

Length: Length of the longest cDNA of this gene.

GCcontent: G+C content of the longest cDNA of this gene.

Details

All human mRNAs were downloaded from NCBI on 22/02/12 by going first to the taxonomy browser, select "Homo Sapiens", then select mRNAs, then follow the link on "manage filters" and made sure that only mRNAs is checked. Then, we selected FASTA format and sent it to a file. We also downloaded the NCBI Entrez Gene ID to NCBI Accession mapping from ftp://ftp.ncbi.nih.gov/gene/DATA/gene2accession.gz which we used to group mRNA transcripts by Entrez Gene identifier. Finally, for each Entrez Gene identifier we picked the longest mRNA and stored its length and G+C content in a data frame called annotEntrez220212 whose row names indicate the corresponding Entrez Gene identifier.

Matching microarray and RNA-seq data from human lymphoblastoid cell lines

Description

ExpressionSet objects containing microarray and RNA-seq count data for 11,508 matching Entrez genes from 36 samples of lymphoblastoid cell lines derived from unrelated Nigerian individuals. These microarray and count data are employed in the vignette of the package GSVA Hanzelmann et al. (submitted). The original experimental data was published by Huang et al. (2007) and Pickrell et al. (2010).

Usage

data(commonPickrellHuang)

Format

huangArrayRMAnoBatchCommon_eset: ExpressionSet object containing filtered, normalized and batch-removed microarray expression values for 11,508 Entrez genes from 36 unrelated Nigerian individuals.

pickrellCountsArgonneCQNcommon_eset: ExpressionSet object containing filtered and normalized RNA-seq read counts for 11,508 Entrez genes from 36 unrelated Nigerian individuals. This table of counts corresponds to RNA-seq data produced at the Argonne sequencing center (see Pickrell et al., 2010).

pickrellCountsYaleCQNcommon_eset: ExpressionSet object containing filtered and normalized RNA-seq read counts for 11,508 Entrez genes from 36 unrelated Nigerian individuals. This table of counts corresponds to RNA-seq data produced at the Yale sequencing center (see Pickrell et al., 2010).

Details

The microarray data was processed from the raw CEL files available at http://www.ncbi.nlm.nih.gov/geo under accession GSE7792. First, only Yoruba samples were considered. Second, data was processed using the Bioconductor oligo package. Quality assessment was performed by calculating NUSE and RLE diagnostics (Bolstad et al., 2005) and discarding those samples that either of the two reported diagnostics was considered below a minimum quality threshold. Third, most samples formed part of family trios and only samples belonging to father or mother were kept. Fourth, using the RMA algorithm (Irizarry et al., 2003) implemented in the rma() function from the oligo package with argument target="core", expression values were background corrected, normalized and summarized into Affymetrix transcript clusters. Fifth, using the getNetAffx function from the oligo package, Affymetrix transcript cluster identifiers were translated into Entrez Gene identifiers resolving duplicated assignments by keeping the transcript cluster with largest expression variability measured by its interquartile range (IQR).

At this point an expression data matrix of 17,324 Entrez genes by 59 samples was obtained and using the scanning date of each CEL file samples were grouped into 5 batches stored in the phenotypic variable Batch within the resulting ExpressionSet. Batch effect was removed by using the QR-decomposition method implemented in the removeBatchEffect() function from the package limma while keeping the sex-specific expression effect by setting the gender sample indicator variable within the design matrix argument. Finally, samples and genes were further filtered to match those from the RNA-seq tables of counts.

The RNA-seq data was obtained by directly downloading the tables of counts processed by Pickrell et al. (2010) from http://eqtl.uchicago.edu/RNA_Seq_data/results, which initially consisted of 41,466 Ensembl genes by 80 and 81 samples corresponding to the RNA-seq data obtained at the Argonne and Yale sequencing centers, respectively. Some of the samples (11 from Argonne and 12 from Yale) were prepared and sequenced twice within each sequencing center. In these cases we kept the sample of deeper coverage obtaining a final number of 69 samples on each table. We further filtered genes with low expression by discarding those with a mean of less than 0.5 counts per million calculated in log2 scale resulting in tables of counts with 17,607 genes (Argonne) and 17,843 genes (Yale) by 69 samples and we kept those genes common to both tables (17,324). Next, we normalized these two tables of counts adjusting for gene length and G+C content using the Bioconductor package cqn (Hansen et al., 2012). The corresponding gene length and G+C content information was extracted from data deposited at the same site from were the tables of counts were downloaded. We further filtered these two normalized tables of counts in order to match the genes and samples obtained after processing the LCL microarray data from Huang et al. (2007). This step required first to translate Ensembl gene identifiers into Entrez gene identifiers and second to match gene and sample identifiers between microarray and RNA-seq data. After these two steps we obtained the two final tables of counts of 11,508 Entrez genes by 36 samples included in this package.

RNA-seq Data by Costa et al. (2021)

Description

Gene and protein expression data published by Costa et al. (2021). The gene expression data consists of normalized log-CPM units of expression derived from bulk RNA sequencing (RNA-seq) of total RNA from archived neonatal dried blood spots (DBS) specimens from 21 extremely low gestational age newborns (ELGANs, < 28 weeks of gestation). The DBS specimens were obtained from 8 females and 13 males, among which 10 where exposed to a fetal inflammatory response (FIR) before birth, and 11 were not exposed. The protein expresion data was obtained from the same specimens, except for a missing one, using a mass-spectrometry assay, and the included data corresponds to the VSN normalized data before and after imputation.

Usage

data(geneprotExpCostaEtAl2021)

Details

The RNA-seq data is contained in a SummarizedExperiment object called geneExpCostaEtAl2021 obtained as follows:

  • Raw 2x75nt paired-end reads in FASTQ files were aligned to the GRCh38 version of the reference human genome, without alternate locus scaffolds (GCA_000001405.15) and including human decoy sequences from hs38d1 (GCA_000786075.2), using STAR version 2.6.0c (Dobin et al., 2013) with default parameters, except for --peOverlapNbasesMin 10 and --sjdbOverhang 74.

  • Aligned reads in BAM files were reduced to a table of counts of 25,221 genes by 84 samples using gene annotations from Gencode v24 and the R/Bioconductor package GenomeAlignments version 1.16.0, and its function summarizeOverlaps. We used specific arguments in the call to this function to restrict the count of genic reads to only those that fell entirely within the exonic regions and aligned to a unique site on the genome, to reflect library preparation protocols, and to avoid counting reads without a matching pair or overlapping multiple features.

  • Lowly-expressed genes were filtered out by discarding those that did not show a minimum reliable level of expression of 10 counts per million reads of the smallest library size, in at least 6 samples. This filtering step led to a final table of counts of 11,279 genes by 21 samples.

  • Normalized log-CPM units of expression were obtained by using the edgeR package (Robinson et al., 2010) as follows. First, we calculated library factors using the TMM algorithm implemented in the function calcNormFactors(), and second we used the function cpm() with default parameters, except for log=TRUE.

The protein expression data is contained in a SummarizedExperiment object called protExpCostaEtAl2021. You may consult the publication for further details on how these data were pre-processed.
