RNA-Seq Workflow and Interpretation

RNA-Seq Workflow and Interpretation

RNA sequencing (RNA-Seq) has become the gold standard for comprehensive transcriptome profiling across biological systems, providing unprecedented insights into gene expression, isoform diversity, and regulatory networks. This intensive course provides a rigorous and structured exploration of RNA-Seq workflows, from experimental design, library preparation, sequencing, quality control, alignment, and quantification, to statistical analysis and biological interpretation. The course begins with an overview of transcriptomics and its role in understanding cellular function, development, and disease mechanisms. Participants learn how RNA-Seq surpasses microarray technologies in sensitivity, dynamic range, and the ability to detect novel transcripts. Fundamental concepts such as transcriptional regulation, alternative splicing, isoform diversity, and expression variability are thoroughly explained. Experimental design strategies are introduced, covering biological replication, sequencing depth, library preparation protocols, and batch effect mitigation. Best practices for RNA extraction, sample quality assessment, and data reproducibility are emphasized. Common pitfalls in RNA-Seq experiments are highlighted, with strategies to avoid them. Data preprocessing and quality control modules cover FASTQ data handling, trimming, adapter removal, and contamination detection. Participants explore alignment-based and alignment-free quantification methods, read mapping strategies, splice-aware aligners, and transcript assembly approaches. Normalization methods and statistical considerations for comparing samples across conditions are explained in depth. Differential expression analysis forms a central component of the course, including count-based modeling, dispersion estimation, multiple hypothesis correction, and interpretation of fold changes. Participants learn to analyze complex experimental designs, such as time-series studies and multifactor experiments. Isoform-level analysis, splicing event detection, and transcript switching are also covered to capture regulatory complexity beyond gene-level expression. Functional interpretation focuses on pathway enrichment analysis, gene ontology, and integration with multi-omics datasets including proteomics and epigenomics. Data visualization techniques, including heatmaps, PCA plots, volcano plots, MA plots, and genome browser tracks, are included to enhance understanding and communication of results. Advanced topics introduce single-cell RNA-Seq concepts, batch correction, and emerging transcriptomic technologies. Ethical considerations, reproducibility standards, and best practices for reporting RNA-Seq studies are integrated throughout. Upon completion, participants will be able to design RNA-Seq experiments, execute computational workflows, perform rigorous statistical analysis, interpret complex expression patterns, and translate findings into biologically meaningful insights relevant for precision medicine, genomics research, and systems biology.
