Synthetic Biology02:55

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Hybridoma Technology01:31

Hybridoma Technology

Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...
Drug Discovery: Overview01:26

Drug Discovery: Overview

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...
G-protein Coupled Receptors01:21

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.
ER Retrieval Pathway01:45

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Area of Science:

  • Biomedical Informatics
  • Semantic Web Technologies
  • Information Retrieval

Background:

  • Current search engines rely on keywords, limiting their ability to answer complex questions.
  • Semantic technologies offer potential for advanced question-answering capabilities.
  • Existing semantic approaches focus on either unstructured text processing or reasoning over structured data.

Purpose of the Study:

  • To introduce GoWeb, a novel approach for semantic search in the biomedical domain.
  • To facilitate question answering by integrating classical search with advanced text-mining and ontological reasoning.
  • To improve navigation and information discovery within large biomedical datasets.

Main Methods:

  • Developed GoWeb, a system combining keyword search, text mining, and ontologies.
  • Evaluated GoWeb on three distinct biomedical question-answering benchmarks.
  • Utilized datasets related to gene functions, symptom-disease relationships, and protein-disease associations.

Main Results:

  • GoWeb achieved 58% success in identifying functional GeneOntology annotations for genes.
  • Demonstrated a 77% success rate in linking symptoms to diseases, improving existing methods by 20%.
  • Attained a 79% success rate in answering protein-disease questions within the TREC genomics challenge.

Conclusions:

  • GoWeb represents a significant advancement in biomedical question answering through its hybrid approach.
  • The integration of web search, text mining, and ontologies offers a promising direction for future semantic search engines.
  • GoWeb is accessible online at http://www.gopubmed.org/goweb for further exploration.
