  • Welcome to this bioinformatics lab on data manipulation using online and server tools.As the theme, we have chosen to study of the interaction between Frataxin and pancreatic cancer.
  • 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

    1. 1. Bioinformatics Data Manipulation:Molecular Online Tools & BioExtract ServerTheme: FXN Gene and Pancreatic Cancer.Lab #1Etienne Z. GnimpiebaBRIN WS 2013Mount Marty College – June 24th 2013Etienne.gnimpieba@usd.edu
    2. 2. Context0. Specification & Aims.Statement of problem / Case study: The FXN gene provides instructions for making a protein called frataxin. This protein is found in cells throughout the body, with the highest levels in the heart,spinal cord, liver, pancreas, and muscles. The protein is used for voluntary movement (skeletal muscles). Within cells, frataxin is found in energy-producing structures called mitochondria. Althoughits function is not fully understood, frataxin appears to help assemble clusters of iron and sulfur molecules that are critical for the function of many proteins, including those needed for energyproduction. Mutations in the FXN gene cause Friedreich ataxia. Friedreich ataxia is a genetic condition that affects the nervous system and causes movement problems. Most people with Friedreichataxia begin to experience the signs and symptoms of the disorder around puberty.Bioinformatics Molecular Online Tools and ServerKeywords:Bio: FXN, Frataxin, pancreatic cancer, CDKN4Math: HMM,Informatics: programing, bioinformatics tools, gettingand exporting dataReduced expression of frataxin isthe cause of Friedrichs ataxia(FRDA), a lethal neurodegenerativedisease, how about liver cancer?Aim: The purpose of this lab is to initiate onlinebiological exploration tools of the human model largescale data study (metabolic, proteic, genomic, …).
