12946 - Molecular Biology

Learning outcomes

The major outcomes will include the acquirement of modern view on the mechanisms underlying cell growth and differentiation, with particular reference to the modulation of gene expression, epigenetics, nuclear dynamics and signaling. Students will be introduced to the molecular dissection of the action of transcription factors, chromatin remodeling and establishment of tissue specific features. The Course will trace the interplay between cell signaling networks and the changes in genome structure and function. Emphasis will be placed on the discussion of several features of stem cell biology, including the concept of pluripotency, paracrine/autocrine/intracrine regulation, and multilineage commitment. Finally, we will dissect the issue of reprogramming of adult somatic non-stem cells to lineages in which these cells would never otherwise appear. These aspects will form the underpinning for Students' guidance through the newly developing fields of Regenerative Medicine and Precision Medicine.

Course contents

At the end of the Course, Students will acquire detailed knowledge on the modern view considering the cytoskeleton, including microtubuli and actin filaments, as a major network in the generation and deployment of information based upon the transport of mechanical, electric and electromagnetic patterning. According to the most recent studies, microtubuli will be presented as a sort of "bioelectronic circuit" essential for biomolecular recognition processes, and for the gene expression modulation. We will discuss the most recent development in the field of intra- and inter-cellular communication through the exchange of electromagnetic radiation (light). We will present the modern frontier of "Photobiomodulation", as a novel strategy to control cellular responses. Within this context, we will also discuss the "autocrine", "paracrine" and "intracrine" regulation of cellular dynamics. We will show details of the nuclear trafficking of signaling molecules and intranuclear signal-transduction mechanisms. The interaction between cytoskeleton and nucleoskelton will be placed in the frame of transcriptional regulation. We will present details on the mechanisms of action of molecular motors (kinesins, dyneins) in the regulation of gene expression and chromatin remodeling. Gene transcription will be presented as a process controlled by epigenetic mechanisms, with particular reference to the genome architecture, and the development of physical vectorial forces capable of controlling gene transcription. The last part of the Course will be dedicated to the modern outcomes of Regenerative Medicine and Precision Medicine, with particular emphasis on the molecular and physical bases of cell reprogramming.
