SASK21001U Bioinformatics analysis of gene expression data
MSc Programme in Animal Science
Driven by the technological progress, biology continuously undergoes a revolution that started in the late 1990s with the sequencing of the human genome. This revolution is on a scale that constantly redefines our basic understanding of biology and reaches deep into human and animal science, for example with respect to diseases and nutrition. Understanding the opportunities that come with the technological development is crucial for strategy planning human and animal science in general.
The course will introduce tools to analyze the high-throughput next generation sequencing (NGS) data generated from a selected range of technologies with high relevance for human and animal science. To this end, basic concepts of sequence alignment and genome analysis will be introduced with special focus on transcriptomics (e.g. gene expression and gene transcript variation). Furthermore, the functional context of genes will be addressed through the studies of biochemical pathways and networks, in which information from the NGS data will be employed to interpret the functional aspects of the genes.
Major software tools introduced and applied during the course are the web-based platform Galaxy for running data intensive bioinformatic analysis pipelines, the statistical software R for statistical computing, and Cytoscape for visualization and interpretation of biological networks.
The aim of the course is to make the participants able to analyze animal related NGS data, to assess the quality of the analysis, and conceptually to account for methodological principles underlying the bioinformatics methods presented in the course.
- key data types and sequence based data sets for transcriptomics
- bioinformatics tools applicable for analysis of a broad range of data from animal transcriptomes
- bioinformatics tools for obtaining in silico driven predictions on animal transcriptomes
- Analyze RNA sequencing data by applying relevant bioinformatic tools
- Assses the quality of sequence data
- Assess the quality of bioinformatic tools
- Apply the statistical software R for data manipulation and analysis
- Acquire relevant data for a given problem
- Assess the relevance of a given bioinformatics method for the data in question
- Interpret the implications of a data analysis in broader context than the specific data analyzed
The course material will mainly be research articles and also involve chapters from textbooks
* Genetics, gene and genome structure
Previous experience with the software R are recommended but not required.
