Transcriptome Assembly from RNA-Seq

Transcriptome Assembly from RNA-Seq

RNA sequencing (RNA-Seq) has revolutionized transcriptomics, allowing researchers to profile gene expression, identify novel transcripts, and uncover alternative splicing events. Transcriptome assembly is a critical step in RNA-Seq data analysis, converting raw sequencing reads into meaningful representations of expressed genes and isoforms. This comprehensive course provides in-depth training in transcriptome assembly methodologies, quality control, analysis pipelines, and functional interpretation. The course begins with an introduction to RNA biology, transcriptomics, and the principles of RNA-Seq. Participants learn about sequencing technologies, library preparation, read quality, and experimental design considerations, including replicates, sequencing depth, and batch effects. Emphasis is placed on selecting the appropriate assembly strategy based on biological questions and data type. Core modules cover computational approaches for transcriptome assembly, including reference-guided (alignment-based) and de novo assembly methods. Participants gain hands-on experience with tools such as HISAT2, STAR, StringTie, Trinity, and Cufflinks. Preprocessing steps, including quality assessment, adapter trimming, error correction, and read filtering, are integrated throughout the workflow. Advanced topics include quantification of transcripts, normalization methods, differential expression analysis, detection of novel isoforms, alternative splicing events, and fusion transcripts. Participants learn statistical approaches for expression analysis, including tools like DESeq2, edgeR, and Ballgown, and techniques for visualization of complex transcriptomic data. Integration with functional genomics, gene ontology, pathway analysis, and multi-omics datasets is emphasized to extract biological meaning from assembled transcriptomes. Case studies demonstrate applications in disease research, developmental biology, cancer transcriptomics, and environmental transcriptomics. Best practices for reproducibility, workflow automation, data management, and documentation are highlighted. Participants learn to structure projects, manage computational resources, optimize pipelines, and generate publication-quality figures and reports. By the end of this course, participants will be able to preprocess RNA-Seq data, perform transcriptome assembly using reference-guided and de novo methods, quantify gene and isoform expression, detect alternative splicing and novel transcripts, integrate functional analyses, and communicate findings effectively. This training equips computational biologists, bioinformaticians, and molecular biologists with essential skills to leverage RNA-Seq for transcriptome-level insights and biological discovery.
