Molecular biology
Course syllabus
The concept of "Precision Medicine" is introduced following the growing knowledge in genetics and molecular biology associated with the availability of clinical data that project new opportunities to personalize patient care and clinical management.
PRINCIPLES OF CELLULAR SIGNALING
The fundamental principles of "cell signaling" interactions mediated by G-protein coupled receptors and/or through coupled receptors with enzymatic activity are introduced. The mechanisms of modulation of signals through the role of 'scaffold' proteins are highlighted.
The role of cellular signaling is developed through the treatment of the molecular mechanisms underlying MEN2 syndromes, they are discussed as a molecular model of alteration of 'tyrosine kinase receptors'; an example of clinical/molecular management in endocrinology.
In addition, as an example of somatic alterations, the role of tyrosine kinase receptors in the onset of acute leukemias is investigated.
GENE EXPRESSION CONTROL
The fundamental aspects related to the regulation of gene and genome expression are highlighted, with particular in-depth analysis of the role played by 'DNA-binding proteins' and transcription regulators.
The mechanisms of regulation of mRNA stability and the role of non-coding RNAs will also be considered.
GENOMIC INSTABILITY
The concepts of genetic/chromosomal instability are discussed with an overview of some models proposed for the understanding of the phenomenon that acts as a motor in neoplastic transformation.
· Li Fraumeni syndrome
Paradigm of the mechanisms by which neoplastic progression acquires functions. p53 is the "onco-suppressor" molecule par excellence, the related syndrome guides us in the dynamics of its mechanism of action.
· RecQ helicases: guardians of the genome
The RecQ helicases represent the guardians of the genome, a model of control of genomic stability, a syndromic paradigm the loss of their function.
MOLECULAR BASIS OF AGING AND RELATED DISEASES
We will explore the biological causes of aging by analyzing in detail the molecular mechanisms involved, discussing the implications of aging in the development of diseases

Acute myeloid leukemias are neoplasms with low genetic instability, we will evaluate what emerges from the genomic and molecular profiles of the new generation· Leukemias 'Core Binding Factor'; a multi-step progression model that harmonizes genetics and epigenetics into a molecular continuum that can suggest new therapeutic approaches.· A->'Editing' RNAs: the "ADAR" side of leukemias. One of the most relevant post-transcriptional changes between the plasticity functions of the genome and its bivalent role in neoplastic transformation is discussed.
GENETIC AND CELLULAR ENGINEERING
We will analyze the molecular bases that allow to manipulate the identity of cells and their genetic content by discussing technological strategies and potential therapeutic approaches

According to the provisions of the CdS, teaching will be delivered in the 8 + 4 hours per CFU mode: 8 frontal hours, consisting of attendance at the scheduled lessons and 4 innovative hours consisting of individual supplementary activities according to the methods described below.
The student will deepen the topic chosen for the composition of the minireview (which will be a determined element for the final evaluation) focusing on the correlation between the molecular mechanisms and an oncological pathology or predisposing condition to the development of a neoplasm of his interest.
The individual supplementary activity aims to provide support for drafting the minireview through a collegial discussion and it will be divided as follows:
o Identification of an oncological pathology or predisposing condition to the development of a neoplasm of interest that has correlations with one of the topics covered in class;
o Study of the link between the information provided by the teachers and the pathological context chosen for the drafting of a minireview in English that will constitute an exam test (See exam methods);
o Drafting of a title and abstract for the minireview (summary of about 250 words) in English that illustrates this association (a plagiarism check will be done);
o Presentation of the proposal in a collective session to be agreed in which everyone will be obliged to participate.
Please note that the individual supplementary activity is mandatory, otherwise you will not be able to take the exam.
Verification of learning
The evaluation of the module is attributed on the basis of an ongoing exam at the end of the course based on the knowledge acquired during the course which will have the value of admission to the evaluation of an individual work consisting in the drafting of an original Minireview on a theme chosen by the student in the field of molecular mechanisms underlying neoplastic processes (molecular mechanisms of cancer) written in English.
Only students who have attended at least 75% of the lessons, passed the test in progress and sent the minireview by e-mail to both teachers (Prof. Beghini and Pasini) within the established deadline (deadline) for each exam, will be admitted to the evaluation of the Molecular Biology module.
