Summary
Positional MEDLINE (PosMed) is a Semantic Web engine that ranks biomedical resources by association with phenotypes. It is redesigned to interpret genetic variants and enhance mouse bioresource utility for disease gene discovery.
Area of Science:
- Biomedical Informatics
- Genomics
- Bioinformatics
Background:
- Positional MEDLINE (PosMed) is a Semantic Web Association Study engine used since 2005 for in silico positional cloning.
- It ranks biomedical resources like genes, metabolites, and diseases based on associations with phenotypic keywords.
- These associations are derived from a Semantic Web of biological databases.
Purpose of the Study:
- Redesign PosMed as a workbench to discover functional interpretations for genetic variants from exome sequencing.
- Enhance the value of mouse bioresources by inferentially associating them with phenotypes.
- Improve the discovery of candidate disease genes and functional interpretations of genetic variants.
Main Methods:
- Established text-mining rules for biomedical documents through human curation.
- Created extensive, accurate links between genes and documents.
- Integrated 20 public databases and four original datasets to associate phenotypic keywords with mouse resources.
Main Results:
- PosMed is redesigned as a workbench for functional interpretation of genetic variants.
- Demonstrated enhanced utility of mouse bioresources through inferential phenotype association.
- Successfully linked phenotypic keywords to mouse resources using a comprehensive data integration.
Conclusions:
- The redesigned PosMed workbench facilitates the interpretation of genetic variants in human disease.
- PosMed enhances the utility of mouse models in biomedical research by enabling phenotype-based associations.
- The Semantic Web approach provides a powerful framework for integrating diverse biological data for discovery.

Genome Annotation and Assembly
20.5K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Genome-wide Association Studies-GWAS
15.2K
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.

Ribosome Profiling
4.0K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Genomics
39.6K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
