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

Annotate samples with metadata Start Here
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 DESeq2 to get differentially expressed genes between Dex vs Run DESeq2 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 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 “Dex vs.Unt” and “Alb vs. Unt” datasets
