Genetics of aging

Course objectives

There is much evidence on the involvement of genes in the control of life span and senescence. These two aspects of the life cycle of an organism can therefore be considered two dissectionable phenotypes through a mutational analysis. The course aims to illustrate the most relevant results obtained in different model systems using formal genetic and molecular approaches. Acquired knowledge: Students who have passed the exam will be able to know and understand: - the genetic theories of senescence - the main mechanisms of senescence - the relationship between aging and cancer Acquired skills: Students who have passed the exam will be able to: - to evaluate which genetic techniques are most appropriate to solve scientific problems concerning senescence and length of life - evaluate the importance of model organisms for the study of aging and related diseases Autonomy of giudiuzio: Students who have passed the exam will be able to: - critically analyze some aspects related to aging

Prerequisites
It is essential to have passed the exams of Genetics, Molecular Biology and Biochemistry In particular, it is necessary to know the basic concepts of Genetics, that is, the laws of heredity, the concept of gene, gene and chromosomal mutations, the structure of DNA and proteins

Teaching mode
The 48 hours of lectures will be held in the classroom with the use of Powerpoint files on the program topics divided into two modules of 24 hours each (2X3 CFU)
Frequency
Class attendance is not mandatory.
Exam mode
The oral exam consists in exposing a topic at will to evaluate the communication skills of synthesis and analysis; in answering one or more questions chosen by the teacher to assess the level of depth of the study on the topics of the program and to evaluate the student's ability to make connections and organize a speech in a logical way. The questions refer to the topics presented during the lessons and also to the laboratory exercises. The evaluation is expressed in thirtieths (minimum mark 18/30, maximum mark 30/30 with honors). To pass the exam with an assessment of 30/30 it is necessary to answer all the questions in an exact, logical, in-depth way and with language properties, demonstrating reasoning skills and being able to contextualize concepts and examples.
