Syllabus
Obiettivi Formativi
The course aims at clarifying the integration of main cellular components and biochemical reactions and at exploring proteomics tools to investigate protein levels, localization and function. Therefore, the course aims at teaching fundamental basic topics, needed for the comprehension of many other courses in the BMS course.
The main objectives of the course are:
-to understand the molecular factors and mechanisms of biochemical regulation of cell function (cellular biochemistry)
-to acquire knowledge about post-genomic methods in cellular biochemistry (proteomics).
Expected results:
1. To be able to describe the main molecular factors and pathways discussed during lessons (e.g., protein targeting, autophagy, biosignalling)
2. To analyze complex cellular mechanisms, by selecting the most important information in scientific literature.
3. To understand how cellular biochemistry can be studied by the means of proteomics.
4. To be able to use technical terminology.
5. To be able to critically read and comprehend proteomics literature.
6. To apply theoretical knowledge during the lab experience integrated in the course.

Prerequisiti
A solid background in Cytology, Biochemistry and Molecular Biology.
Metodi didattici
Teaching activity consists of theoretical (40 hrs) and practical (24 hrs: 12 for all students + 12 for Double Degree students) lectures with hands-on activity. Seminars by experts in the field will be considered for particular topics. A lesson will be structured as a journal club, in order to read and critically interpret proteomics literature. A visit to a proteomics facility is planned, in order to see different technological platforms in the proteomics field.
Students will be asked to participate critically to the discussion during journal clubs.
Power point presentations (together with original papers where information have been retrieved from) will be used during lessons and uploaded the day before the lesson on the e-learning platform.

Verifica Apprendimento
The assessment of intended learning outcomes will be made with a final oral exam and it consists of two questions. The first aims at discussing a general cellular biochemistry content (normally the title of a lesson), in order to evaluate the autonomy to organize a scientific discussion, as well as knowledge and understanding. The second question is more specific and focused on a specific molecular pathway or a specific proteomics approach.
Precision in terminology and content correctness are needed to pass the exam.
Ability to integrate contents and to apply knowledge to practical examples will be considered to get higher marks (28-30 and honours).
