Prerequisites

It is necessary that the student has achieved some basic competences in Cell Biology, Biochemistry and Molecular Biology, and especially a sufficient knowledge about the structure and functions of DNA and proteins.

Objectives and Contextualisation

The course aims to introduce the student to the basic mechanisms of recombinant DNA technology, with the aim of having a general view of the possibilities offered by these techniques in medicine. The Recombinant DNA Techniques have brought the possibility of applying different methods and strategies for the treatment of multiple pathologies. For example, it has allowed mass production of molecules of therapeutic interest such as insulin, growth hormone, etc. It has also allowed the development of techniques for the molecular diagnosis of pathologies. And finally, it allows the possibility of offering a cure to many diseases through the use of cell and / or gene therapy, which will surely lead to an enormous development of regenerative medicine in the coming decades. The content of the subject will allow to have knowledge of the bases that are behind the enormous possibilities that the application of these techniques has in their future medical practice.

Content

The contents of the subject are structured in 6 blocks:

1.- General concepts about the structure and function of proteins and nucleic acids.

In this block, the general concepts about the structure and function of nucleic acids and proteins will be explained. This is a block that aims to review concepts that students must have already seen in various core subjects of the first year: levels of structure of proteins and nucleic acids, how the flow of genetic information occurs in cells and what are the main mechanisms of regulation of gene activity. With this, we make sure that these basic concepts are well established in all students.

2.- Recombinant DNA techniques.

In this block, students will know the theoretical and practical elements (through laboratory practices) to generate recombinant DNA. Among them, the obtaining of DNA fragments by the use of restriction enzymes; the binding of DNA fragments using the enzyme DNA ligase; the vectors that are used to introduce the DNA into the cells or organisms and what are the possible mechanisms to introduce the foreign DNA into the host cells; how can we detect the clients that carry the gene we have introduced, and how can we clone a gene or DNA fragment?

3.- Production of molecules of medical interest by recombinant DNA.

In this block, students will know the methods used to obtain molecules of medical interest through molecular biology. We will see the examples of obtaining recombinant insulin, recombinant growth hormone, vaccines, interferons, etc.

4.- Molecular diagnosis.

The fourth block is dedicated to the application of molecular biology techniques to the diagnosis of pathologies. The students will know how, from the property that the nucleic acids have to hybridize when they have complementary sequences, several strategies have been designed that allow the diagnosis of diseases. Special emphasis will be placed on those that are commonly used in hospital analysis laboratories and students will also be illustrated with the importance that these techniques have in forensic medicine.

5.- Gene and cell therapy.

In this block, the underlying methodology in cellular and gene therapy will be discussed. Not only the techniques for the production of stem cells will be treated, but also the methods that allow us to genetically modify these cells. We will also see the aspects that still limit the clinical use of these techniques, as well as legal and bioethical aspects. Students will also know the fundamental concepts and goals of gene therapy. The difference between ex vivo and in vivo gene therapy, as well as the current status of gene therapy, will be explained. Your promises and realities For this, we will analyze concrete cases of successes and failures in the use of this technology.

6.- Use of genetically modified animals in biomedical experimentation.

Finally, the last block is intended for genetically modified animals and their medical interest. The students will know the basic methods that allow generating a transgenic animal or a null mutant and will explain the interest that these animals have as experimental models for the study of human pathologies and for the production of substances of medical interest.

Methodology

The subject is based on a theoretical-practical methodology.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

In addition to the theoretical exam (40% of the final grade), the student will have to perform laboratory practices, where he will perform the complete process of cloning a gene in bacteria and its expression in eukaryotic cultures. For the evaluation, the dossiers of practices and the attitude in the laboratory will be taken into account. This part will represent 20% of the final grade. A recovery exam of the theoretical part will be scheduled for students who want to upload the note of this part.

40% will come from the assessment of problem and case solving classes. It will be assessed if the student has correctly performed the exercises that have been proposed throughout the course. The students will have to deliver the resolution of them on the agreed days.

The absence to more than one day of practices will prevent the qualification of that part of the subject. Failure to complete the exercises will prevent the qualification of this part of the subject.

Students who do not take the theoretical and practical assessment tests will be considered as not evaluated and will exhaust the rights to the registration of the subject.
