The Nucleus01:25

The Nucleus

6.2K
The nucleus is a membrane-bound organelle that acts as a control center in a eukaryotic cell. It contains chromosomal DNA, which controls gene expression and precisely regulates the production of proteins within the cell. In contrast, the DNA inside the mitochondria and chloroplast only carries out functions that are specific to those organelles.
Arrangement of DNA within Nucleus
The regulation of gene expression inside the nucleus is dependent on many factors, including the DNA structure. The...

Natural and Artificial Concepts

743
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Systems Biology

Background:

  • Traditional gene ontologies rely on manual expert curation, which can be time-consuming and potentially biased.
  • Large-scale molecular interaction networks offer a rich source of data for inferring biological relationships.
  • There is a need for data-driven ontologies that complement manually curated resources.

Purpose of the Study:

  • To introduce the Network-extracted Ontology (NeXO), a gene ontology computationally inferred from molecular networks.
  • To describe the development and features of the NeXO Web platform, an online resource for accessing and analyzing NeXO.
  • To provide a user-friendly interface for visualizing, browsing, and performing enrichment analysis with both NeXO and the Gene Ontology.

Main Methods:

  • NeXO was constructed by integrating evidence from hundreds of thousands of gene and protein interactions.
  • The NeXO Web platform was developed using state-of-the-art web technologies and visualization techniques.
  • The platform enables term enrichment analysis using both NeXO and the Gene Ontology.

Main Results:

  • The NeXO Web platform provides an intuitive graphical user interface for exploring a data-driven gene ontology.
  • The platform facilitates the visualization and browsing of cellular components and processes inferred from molecular networks.
  • Users can perform term enrichment analysis, comparing data-driven NeXO with manually curated ontologies.

Conclusions:

  • NeXO represents a novel, computationally derived gene ontology that complements existing manually curated resources.
  • The NeXO Web platform offers a powerful and accessible tool for biological data exploration and analysis.
  • This approach integrates large-scale interaction data to provide a global hierarchy of cellular functions and components.
