Bulk RNA-seq CLCGx Workflow
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

Start analyzing the data and create visualization plots in Partek Flow
Browse imported count matrix data
Run PCA 1 2 3
Create sample correlation plots
Run DESeq 2 to get differentially expressed genes between Dex vs. Unt samples
Filter DE genes
Display DE genes in a dot / violin plot
Create a heatmap using hierarchical clustering
Hands on exercise • Import “Alb vs. Unt” CLCGx created expression browser dataset into Partek Flow • Create a PCA Plot • Run DESeq 2 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 “Dex vs. Unt” and “Alb vs. Unt” datasets
