Learning Objectives
The course aims to provide students theoretical knowledge and practical skills of techniques for the analysis of gene expression. The course will provide an overview of classical techniques (Hybridization Method, Northern Blotting) for the detection / measurement of mRNAs and the most modern techniques (real time qPCR) of accurate quantification of single gene expression levels. Notions on microarray and RNA-Seq techniques (based on NGS sequencing) will be provided for the evaluation of different profiles of gene expression (transcriptome). The laboratory experience will concern the organization of a strategy to evaluate the expression levels of potential target genes involved in a physiological or pathological process. To obtain results biologically significant of gene expression, housekeeping genes to normalize the data and appropriate statistical tests will be used.
