Gene Expression Quantification Methods

Gene Expression Quantification Methods

Quantifying gene expression accurately is essential for understanding cellular processes, regulatory mechanisms, and disease states. This course provides comprehensive training in methods for measuring gene expression, covering both experimental and computational approaches across RNA-Seq, microarrays, and single-cell technologies. Participants begin with an introduction to gene expression biology, transcriptional regulation, and the experimental design principles required for robust expression studies. The course emphasizes quality control, normalization, and statistical considerations for accurate quantification. Core modules cover RNA-Seq workflows, including library preparation, sequencing, read mapping, transcript assembly, and quantification using tools such as STAR, HISAT2, Salmon, and Kallisto. Participants also learn differential expression analysis using DESeq2, edgeR, and Limma, as well as functional enrichment analysis for pathways and gene ontology. Advanced topics include single-cell RNA-Seq quantification, batch effect correction, spike-in controls, normalization strategies, integration with proteomics and epigenomics datasets, and visualization techniques for gene expression data. Participants gain hands-on experience analyzing large-scale datasets and interpreting biologically meaningful patterns. Case studies highlight applications in cancer biology, developmental biology, immunology, and neuroscience, demonstrating how accurate quantification informs experimental hypotheses and clinical research. Ethical considerations, reproducibility, and proper documentation practices are emphasized to ensure high-quality, reliable results. By the end of this course, participants will be able to design gene expression experiments, preprocess and normalize expression data, quantify expression levels, perform differential analysis, integrate multi-omics datasets, visualize results effectively, and communicate findings. This training equips bioinformaticians, molecular biologists, and genomics researchers with essential skills to measure and interpret gene expression accurately across diverse biological contexts.
