Airway smooth muscle cells

Himes BE, Jiang X, Wagner P, Hu R, Wang Q, Klanderman B, Whitaker RM, Duan Q, Lasky-Su J, Nikolos C, Jester W, Johnson M, Panettieri R Jr, Tantisira KG, Weiss ST, Lu Q. “RNA-Seq Transcriptome Profiling Identifies CRISPLD2 as a Glucocorticoid Responsive Gene that Modulates Cytokine Function in Airway Smooth Muscle Cells.” PLoS One. 2014 Jun 13;9(6):e99625. PMID: 24926665. GEO: GSE52778.

From the abstract, a brief description of the RNA-Seq experiment on airway smooth muscle (ASM) cell lines: “Using RNA-Seq, a high-throughput sequencing method, we characterized transcriptomic changes in four primary human ASM cell lines that were treated with dexamethasone - a potent synthetic glucocorticoid (1 micromolar for 18 hours).”

Downloading data

Prior to downloading the data, first, we need to install the NCBI’s sra-tools using conda:

conda install -c bioconda sra-tools

The prepare a list of SRR accession numbers of interest to fetch FASTQ data:

Check SraAccList.txt (i.e., cat SraAccList.txt):

Once the list of wanted SRA accession IDs is ready, use a PBS Pro submission script to fetch all the sequences. Note, data will be downloaded to the folder where the job is submitted. Example script (fetch_SraAccList.pbs):

Pre-processing of public data

Downloaded public data for the airway smooth muscle project show size differences between ‘Read 1’ and ‘Read 2’ FASTQ files. Prior to running the nextflow nf-core/RNAseq pipeline, downloaded raw data will be quality checked using default trim galore options:
