Today’s goal:
...
Copy the “salmon.merged.gene_counts.tsv” to your laptop and we will use it for statistical analysis using BioJupies (see below)
Differential gene expression analysis
Differential expression analysis using https://maayanlab.cloud/biojupies/analyze
From session 2, we will use the feature counts generated using the ‘star_salmon’ parameter setting. Either copy the relevant files (see below) to your laptop from the HPC or download the files below.

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).”
