Questions and Answers

What is the aim of using bioinformatics in the disease-based approach for cancer?

Target identification

What does GWAS stand for and how is it used in cancer research?

GWAS stands for Genome Wide Association Study. It associates the presence of particular genetic variations with the onset of the disease, helping identify subpopulations with different patterns in disease progression.

What is the purpose of drug repositioning in the drug-based approach?

Identifying new indications for existing drugs and using them to treat diseases other than the drug's intended disease

How does machine learning contribute to the drug-based approach in identifying potential drug-disease associations?

Study Notes

Definition of Bioinformatics

  • Bioinformatics is the application of computational tools and analysis to capture and interpret biological data.
  • It is an interdisciplinary field that combines computer science, mathematics, physics, and biology.
  • Bioinformatics is essential for managing data in modern biology and medicine.

Bioinformatics Approaches

Disease-based Approach

  • Dependent on the type of disease under consideration (e.g., cancer, genetic disease, infectious disease).
  • Uses data science, machine learning, and statistical approaches to identify abnormal patterns correlating with disease processes.
  • Aims to identify key drivers of cancer and determine actionable genetic targets.

Large Repositories for Cancer Data

  • ICGC, GDC, and TCGA are large repositories for cancer data.
  • Function: better molecular characterization and understanding to search for novel drug targets.

Identifying Genetic Targets

  • Genome-wide association studies (GWAS) associate genetic variations with disease onset.
  • GWAS identifies subpopulations with genetic variations showing different patterns in disease progression.

Drug-based Approach

  • Drug repositioning and open-source drug discovery.
  • Enables faster, cheaper, and more efficient translation to the clinic, with reduced duration.
  • Examples: Viagra, Thalidomide.

Machine Learning in Drug-based Approach

  • A method of data analysis that automates analytical model building.
  • Predicts potential associations between marketed drugs and diseases.
  • Utilizes multiple similarities of drugs and disease properties as features.
