| 10629482 | epigenetics of gene expression [BIOS-08/A] [ITA] | 1st | 1st | 6 |
Educational objectives General aims
This course aims to present how gene expression is also controlled by reversible and inheritable phenomena such as DNA methylation, histone modification and non-coding RNA activities. These processes may operate over the regular genetic control and represent the "epigenetic space" of regulation. Students will learn how epigenetic processes occur in different organisms and control vast array of biological functions, such as tissue/organ regeneration, X-chromosome inactivation, stem cells differentiation and genomic imprinting. The epigenetic aberrations underlying many diseases, including cancer, disorders of the nervous systems, and aging will be also discussed.
Specific aims
• Preliminary knowledge
The student who addresses this course must possess the basic notions of molecular biology (indispensable), genetics (important) and biochemistry (important).
• Knowledge of the student at the end of the course:
With this course the students acquire the knowledge of a level of regulation of gene expression that acts over the genetic one, but on which it depends. With particular regard to the interaction with the environment around us.
• Acquired skills of the student with this course
The student knows how to deal with issues concerning the regulatory aspect at the base of the main cellular processes; has the fundamentals to be able to read and understand a scientific article of high detail
• Critical and judgmental skills acquired at the end of the course
Through the knowledge of the principles and details of epigenetic regulation, students acquire a good critical and scientific judgment of these problems
• Communication skills on course content
The students are evaluated not only on their specific knowledge of the contents of the study program, but also to know how to expose the issues in question with balance, properties of scientific language and in-depth study.
• Ability to continue independently
In this regard, students will have acquired knowledge and critical skills in the field of epigenetic regulation and will be able to look with a new perspective on the main cellular processes that they will encounter in their scientific career.

| 10626145 | EPIGENETICS [BIOS-14/A] [ITA] | 1st | 1st | 6 |
Educational objectives Epigenetics is the study of heritable changes in gene expression that do not involve changes in the DNA sequence.The course aims to discuss and explore the molecular mechanisms that regulate epigenetic phenomena (chromatin remodeling, histone modification and histone code, heterochromatic proteins, DNA methylation, RNA interference) and the cellular processes that exploit this kind of regualtion (genomic and chromosomal imprinting, facultative heterochromatin, chromosome elimination, position effect of variegation and paramutation).
In addition this course will allow students to learn modern approaches to study the chromatin modifications. We will examine most interesting non-canonical genetic events that involve epigenetic mechanisms. In nature, in fact, exist many variations of basic biological processes, such as meiosis and mitosis, and chromosomal structures, such as telomeres and centromeres. The aim is to demonstrate that the study of non-canonical genetic systems allows to obtain meaningful information about their evolutionary significance and the corresponding canonical processes. A further goal is to illustrate the biology of transposons and their role in gene expression and genomic organization.

| 10628728 | Genome evolution [BIOS-14/A] [ENG] | 1st | 1st | 6 |
Educational objectives The course aims to provide students with a solid theoretical foundation in genome evolution, highlighting the molecular mechanisms that drive its transformation over time. Particular attention will be given to the development of critical thinking, the ability to read, understand and analyse scientific articles, and to interpret raw data from applied genomics. We will explore what composes genomes, how they are organised and reshaped, examining the processes that shape their architecture: gene duplication, transposition, recombination, drift and selection. Mutagenesis will be treated not only as a source of variation, but as an ambivalent force — a driver of evolution and, at the same time, a threat to genomic stability. We will compare genomic, genetic and epigenetic organisation from simple eukaryotes all the way to ourselves. Particular focus will be dedicated to the human genome and pathological states: tumour genome evolution — with its structural instability, cycles of clonal selection and accumulation of driver mutations — represents a paradigmatic example of how evolutionary principles operate in real time within a single organism. The subject integrates genetics, genomics — including recent developments in the fields of pangenomics and genetic engineering — epigenomics, population genetics, molecular biology, mathematics and statistics into a unifying perspective, building also on knowledge acquired in other courses. The practical components will guide students to formulate, design and test a new scientific hypothesis in the field, critically read the literature, and develop a project grounded in the curriculum covered.
