Learning objectives

The course aims at enabling the student to understand the key biochemical techniques and to apply the acquired knowledge to the understanding of a biochemical-clinical report. In addition, the basic biochemical knowledge will be applied to the study of the main biological targets of drugs, thus allowing the student to know and understand the molecular basis of drug action.
LEARNING OUTCOMES
At the end of the course, the student, also using the previously acquired knowledge of biology, organic chemistry and biochemistry, will need to demonstrate knowledge and understanding about:
- The determination of the main physical and structural properties of proteins, such as the molecular weight, the content of secondary structure, the three-dimensional structure, the isoelectric point, the concentration and the properties of interaction with other macromolecules.
- The application of the basic techniques of molecular biology to the production of recombinant proteins and to site-directed mutagenesis of proteins.
- The main techniques of protein purification from complex samples
- The information contained in clinical biochemistry reports
- The biochemical nature of drug targets

Prerequisites

Basic knowledge of biology, organic chemistry and biochemistry

Course unit content

The first part of the course will be focused on the evaluation of key biological macromolecules and the main metabolic pathways as drug targets.
The second part will focus on the most relevant biochemical and molecular biology techniques

Teaching methods

The course will deal with the principal biochemical and molecular biology techniques, also applied to clinical biochemistry. Due to the peculiar nature of the course, the teacher, when possible, will integrate the theoretical lessons with short demonstrations, also with the support of videos. Experts in cutting-edge techniques will be invited to give seminars.
In the second part, lectures will be integrated with one-to-one discussions with the teacher about original articles of the scientific literature.

Assessment methods and criteria

The assessment of the achievement of the objectives will include an oral examination divided into two parts. The first part will include questions relating to the main biochemical techniques and will establish whether the student has attained sufficient knowledge of these techniques, even in relation to the ability to apply that knowledge to the solution of practical problems. The second part will cover the biochemistry of drug targets, with the aim of stimulating the student to understand the molecular mechanisms that underlie drug action. Students may be required to read and discuss scientific papers provided by the teachers.
At the end of the examination two separate evaluations will be given, whose average will be the final grade.
In order to pass the exam, the student must demonstrate to be able to autonomously discuss, using appropriate technical language, all the topics covered in the course, at least at a basic level. Higher levels of detail, understanding of the examples and the careful study of additional material will lead to a higher evaluation.
