  • Hi,Welcome to this bioinformatics course.I’m Etienne, I have a bachelor in Mathematics and informatics, a master in Computer science, a Master Degree in computer science and mathematics for integrative biology, and a PhD in Biotechnology and bioinformatics.During this course, we can name informatician persons who have a background in information systems like a computer scientist. We can also name biology persons who have a background in the life sciences like biology, ecology, agriculture, and so on …[Next]
  • We will talk about fundamentals, career opportunities, and end with the applications of bioinformatics.Don’t try to retain the slide content. The aim of this talk is to give you the overview of bioinformatics as discipline.At the end of the talk, you will be able to indicate what role bioinformatics plays in the whole biotechnology area, some applications examples, and the career opportunities for bioinformaticians. It is an interactive talk, if you have a question, don’t hesitate to interrupt me.
  • Bioinformatics fundamentals depend on the public, here, we have to use some terms most often used byinformaticians, but I’m sure you have strong computational backgrounds.
  • - This part talk about bioinformatics in biotechnology area,- About What Bioinformatics is, Main areas developed in bioinformatics as Metabolic pathway, epigenetics, genomics, transcriptomics andproteomics- In this course we will also talk about2 Key concepts in biology and computer science: the lactose operon, and the central dogma of molecular biology
  • We cannot speak about bioinformatics fundamentalswithout biotechnology. To be referring to the united nation convention on biological diversity, biotechnology describe any technological application that uses for biological systems, living organism, or derivative thereof.....…. thereof to make or modify product or process for specific used, as biochemistry in genetics for genetically modify organism (GMO).From this conception .....
  • From this conception, we can draw a simple map of biotechnology area.This map organized around four principals axes corresponding to:The green biotech is for plants.The red biotech is for animals and healthcare. The Blue Biotech is for aquatic bioengineering. And the White biotech is for the industry area It is important to note that this card is just a representation of the area. For an idea, an reference bioscience dictionary "SpellexBioScience" has identified more than 13,000 biotechnical term in his 2011 version.So you may ask me, where in the figure does bioinformatics fall?Informatics (or information technology with computer) is used in each of these four branches.Then, the bioinformatics (informatics in bio world) tools are used in every apply domains concerning……….……… concerning Agriculture for green Biotech. Bioengineering like biodegradation and bioremediation for white BiotechMedicine for the green engineeringAnd Education area applicationsNow, let us talk about two important fields, the bio world and the informatics one.
  • The Bio world is too large and complex.Large because more than billions different elements to study.From the smallest element, invisible (the nucleotides, ACGTU) to ecosystem and environmental factors. Complex because each element interact with every one, and some interactions are unknownThe researchers in biology work on a specific domain (physiology), on a specialized theme (Cells growth and apoptosis process in cancer development), and for a given moment, researchers work on one subject based on only one hypothesis to verify (in epigenetic context, DNA methylation modify the cells growth profile).The problem here is having the right information at a given moment in their research process.
  • Fig. Historical milestones that have placed bioinformatics at the heart of 21st century biology, from the determination of the first amino acid sequence, to the development of an archive of 500 billion nucleotide sequences. Some major milestones are denoted in black; key computing innovations are indicated in purple; example databases are indicated in blue; organizations and institutions in green; numbers of sequences in red, the growing mass of which is highlighted both in the red curve and the background gradient – the impact of genomic sequencing in the mid ‘90s is clear.
  • In the other hand, we have the informatics worldSpecialize on information manipulation (remind that information is not data).
  • In this focus we have the bioinformatics world which rotates about:
  • We have spoken about biological species and interactions between them. the main issue is how mathematician can understand these interactions? Biologists propose two key tools in this direction. the lactose operon to detail the mechanism of gene expression, and the central dogma of molecular biology for interactions.The gene regions of the DNA in the nucleus of the cell is copied (transcribed) into the RNA andRNA travels to protein production sites and is translated into proteins. In short, DNA , RNA Proteins, is the Central Dogma of Molecular Biology. Imagine, there are trillions of cells in your body, the DNA of each of them is churning out thousands of RNAs which in turn cause thousands of proteins to be produced, every moment. One of them is making your hair strong, another giving the glitter in your eyes, another one carrying oxygen to different parts, and yet another one helping in the making of proteins themselves!No wonder that famous life scientist Russel Doolittle exclaimed: “We are our proteins”
  • With the study of the lactose operon, François Jacob, André Lwoff and Jacques Monod were the first scientists to describe a system for regulating gene transcription. They propose the existence of two classes of genes that differ in their function: the structural genes and regulatory genes. It is from this work was born the concept of gene regulation. (Nobel Prize for Physiology or Medicine in 1965).
  • Rearrange for poster
  • Research and academic institutes have also become big players in the employment market as more candidates look to acquire a PhD and some essential researching skills in the hope that it would lead to better opportunities in the future. 
  • This figure represents an informatician’s perception of bioinformatics. So Bioinformatics has many side view applications.Biology, pharmacology, ….Each application side is accessible through an ad hoc interface adapted to the user's environment.
  • In the other hand, we can observe bioinformatics like an integrate based tool, process and databank according to the aims of our work.In that case, we have
  • In all cases, The practice of bioinformatics depends on several parameters. One of the most important is the context and profile of the practitioner. Thus, a basic user is a specialist in life sciences, meaningwe have different practices.From a biological standpoint, the practice has taken back in bioinformatics computing tools useful to the resolution of known biological problems (BIO-INFORMATICS).From a computing point of view, bioinformatics is the construction program and processes relevant to biology (computer-or computational Biology).And here lies the relationship between bioinformatics and computational biologyWhy do I bother to take this precision?What emerges from the perception of bioinformatics is a biologist and bioinformatician will be both a computer scientist. there are computer scientists who work on bioinformatics with a rudimentary level in biology gained during their experience.For aninformatician, bioinformatics refers to threethings:- Data manupulation- Programmbuiding- Model designingFor example….next
  • This is the lab template: The context is a biological context based on a real biological problem. And a given hypothesisI don’t use computer science, strong word.When you read this template, you have a different view than an informatician.You want to understand the process to build the used tools.The architecture of the systemThe algorithm implementationThe quality of the resulting dataAnd so on
  • This model illustrates the growth of a tumor and how it resists chemical treatment. A tumor consists of two kinds of cells: stem cells (blue) and transitory cells (all other colors).HOW IT WORKSDuring mitosis, a stem cell can divide either asymmetrically or symmetrically. In asymmetric mitosis, one of the two daughter cells remains a stem cell, replacing its parent. So a stem cell effectively never dies - it is quasi reincarnated after each division. The other daughter cell turns into a transitory cell that moves outward.Young transitory cells may divide, breeding other transitory cells. The transitory cells stop dividing at a certain age and change color from red to white to black, eventually dying.A stem cell may also divide symmetrically into two stem cells (blue). In this example the original stem cell divides symmetrically only once. The first stem cell remains static, but the second stem cell moves to the right. This activity, in which the cell advances into distant sites and creates another tumor colony, is called metastasis. Notice that the metastasis is red. It is made of cells that die young, when they are still red, rather than ending as black dots as in the static tumor. As the disease progresses, cells die younger and younger.
  • Epidemiologists use bioinformatics models as well. Our last example models epidemiology inquiries.HIV or other diseases can be modeled to show how it will spread or subside under certain conditions.

This protein is found in cells throughout the body, with the highest levels in the heart, spinal cord, liver, pancreas, and muscles. The Reduced expression of frataxin is theprotein is used for voluntary movement (skeletal muscles). Within cells, frataxin is found in energy-producing structures called mitochondria. Although its function is not fully understood, frataxin appears to help assemble cause of Friedrichs ataxia (FRDA), aclusters of iron and sulfur molecules that are critical for the function of many proteins, including those needed for energy production. Mutations in the FXN gene cause Friedreich ataxia. Friedreich ataxia is a genetic lethal neurodegenerative disease, howcondition that affects the nervous system and causes movement problems. Most people with Friedreich ataxia begin to experience the signs and symptoms of the disorder around puberty. about liver cancer? 0. Specification & aims Resolution process Aim: T1.
