Prerequisites for admission
The student will use the information learned in the courses of Biology, Chemistry and Biochemistry, Genetics to explain the molecular mechanisms related to some human biological systems and the origins of some pathological states.
Assessment methods and Criteria

Teaching methods
Due to the university's anti-Covid recommendations, teaching in the AA 2021-2022 will be probably delivered in mixed mode: while some students will be present in the classroom in compliance with the maximum number allowed following rotation criteria, the others will follow the same lessons synchronously using the Microsoft Teams digital platform. According to the provisions of the CdS, the teaching will be provided in the 8+4 hours for CFU mode: 8 hours of head time, consisting of attendance at the scheduled lessons and 4 alternative hours consisting of individual supplementary activities as described below.

Course syllabus
PRINCIPLES OF CELLULAR SIGNALING
The fundamental principles of cell signaling interactions mediated by G-protein-coupled receptors and/or through receptors coupled with enzymatic activity are introduced. Signal modulation mechanisms are highlighted through the role of 'scaffold' proteins.
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 deepened.
CONTROL OF GENE EXPRESSION
The fundamental aspects related to the regulation of gene and genome expression are highlighted, with particular in-depth study of the role played by DNA-binding proteins and transcription regulators.
Mechanisms for regulating the stability of mRNAs and the role of non-coding RNAs will also be taken into account.

Acute myeloid leukemias are neoplasms with low genetic instability, we will evaluate what emerges from the next generation genomic and molecular profiles

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.
