Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...
Schemas01:42

Schemas

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
Mass Spectrometry: Overview01:19

Mass Spectrometry: Overview

Mass spectrometry is an analytical technique used to determine the molecular mass and molecular formula of a compound. The basic principle of mass spectrometry is to generate ions from the analyte molecule and measure these ion abundances against their molecular mass. One common type of ionization, known as electron ionization or EI, bombards the analyte molecules in the gas phase with high-energy electron beams. The electron beams displace an electron from the molecule and leave behind a...
Genome Annotation and Assembly03:36

Genome Annotation and Assembly

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.
Mass Spectrum01:23

Mass Spectrum

A mass spectrum is the graphical representation of the relative abundance of the charged fragments in an analyte plotted against their mass-to-charge ratio (m/z). The plot's x-axis represents the ratio of the mass of the charged fragment to the number of charges it carries. The y axis of the plot represents the relative abundance of each charged species. The relative abundance is calculated from the signal intensity of each charged species recorded at the detector. The most intense signal (the...
Tandem Mass Spectrometry01:21

Tandem Mass Spectrometry

Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...

  • Data Science

Background:

  • Global bioinformatics research databases are large and heterogeneous, presenting challenges in cross-integration, retrieval, security, and openness.
  • Existing Semantic Web-based integration frameworks like SciNetS.org manage millions of data records but face limitations in data query capacity and analysis of raw data.

Purpose of the Study:

  • To develop a novel interface for secure and efficient access to integrated and raw life sciences data.
  • To overcome the limitations of existing tools like SPARQL for querying and analyzing heterogeneous bioinformatics databases.

Main Methods:

  • Developed a lightweight Semantic-JSON interface compatible with programming languages like Perl and Ruby.
  • Integrated 192 mammalian, plant, and protein life sciences databases (8.2 million records) as Linked Open or Private Data (LOD/LPD) using SciNetS.org.
  • Enabled secure access to both linked and raw data fragments.

Main Results:

  • The Semantic-JSON interface successfully facilitated access across 28 million semantic relationships.
  • Enabled diverse biological applications, including genome design, sequence processing, phenotype database inference, and full-text search.
  • Provided specialized tools for data analysis using raw original data, enhancing research capabilities.

Conclusions:

  • The Semantic-JSON interface effectively addresses challenges in accessing and analyzing large-scale, heterogeneous bioinformatics data.
  • It enhances collaborative research by providing secure, flexible access to both linked and raw life sciences data.
  • The developed system supports a wide range of advanced bioinformatics applications and promotes data-driven biological discovery.
