Bulk RNA-seq workshop topics • Brief introduction to RNA-Seq experiments • Analyze RNA-seq data • Dexamethasone treatment on airway smooth muscle cells (Himes et al. PLos One 2014) • Download seq reads from EBI-ENA/NCBI SRA • Import reads to CLC Genomics Workbench • Align reads to Reference Genome • Estimate expressions in the gene level • Estimate expressions in the transcript isoform level • Statistical analysis of the differential expressed genes and transcripts • Create Heat Map, Volcano Plots, and Venn Diagram

Annotate samples with metadata Start Here
Start analyzing the data and create visualization plots in Partek Flow
Run PCA 1 2 3
Run DESeq2 to get differentially expressed genes between Dex vs. Untsamples
Hands on exercise • Import “Alb vs. Unt” CLCGx created expression browser dataset into Partek Flow • Create a PCA Plot • Run DESeq2 software and generate a differentially expressed gene list - Alb vs. Unt • Display DE genes in dot or violin plots • Create a heatmap displaying clustered samples in rows and clustered genes in columns • Create a Venn diagram showing overlap between DE genes (p-value <=.05, FC <= -1.5 and >=1.5) produced by “Dexvs.Unt” and “Alb vs. Unt” datasets
