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.

Bridging Courses

A good knowledge of basic Molecular Biology is required to understand the course contents.

Learning Achievements (Dublin Descriptors)

D1 - Knowledge and ability of comprehension. Students will have to demonstrate that they have acquired the theoretical-practical knowledge of the experimental techniques and be able to organize the experimental design for an analysis gene expression study. Finally, students will have to be able to develop an appropriate analysis of the results to understand their biological significance.

D2 - Ability to apply knowledge and comprehension. Students will have to demonstrate that they have mastered the methodologies covered during the course and to evaluate their use in an experimental context, to develop a correct experimental design related to gene expression analysis and to evaluate their biological significance.

D3 - Autonomy of judgement. Students must be able to evaluate and apply the methodological knowledge obtained during the course and be able to independently process the results obtained in the experimental phase.

D4 - Communication skills. Students will have to demonstrate that they have the ability to independently find the scientific publications related to the course, and the ability to improve their theoretical and practical knowledge in the field of gene expression analysis technologies.

D5 - Learning skills. Students will demonstrate the ability to independently increase the basic knowledge of newly emerging fields of molecular biology

Teaching Material

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

Teaching, Attendance, Course Books and Assessment

Teaching

Learning activity will mainly consist of lab experiences. Lectures will be intended to supply the theoretical knowledge of the leading techniques employed in analysis of gene expression. 

The schedule will be introduced at the beginning of the course.

Innovative teaching methods
Attendance

It is strongly suggested that students attend the lab hours.

Course books

Assessment

The final assessment consists of a written multiple choice test and oral exam. Students will elaborate an oral presentation on their laboratory experiments in appropriate scientific language.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
