  2. Gene regulatory network - Wikipedia

    en.wikipedia.org/wiki/Gene_regulatory_network

    Structure of a gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell.

  3. Biological network inference - Wikipedia

    en.wikipedia.org/wiki/Biological_network_inference

    Biological network inference is the process of making inferences and predictions about biological ... Gene regulatory networks can be modeled in numerous ways ...

  4. GeneNetwork - Wikipedia

    en.wikipedia.org/wiki/GeneNetwork

    GeneNetwork is a combined database and open-source bioinformatics data analysis software resource for systems genetics. [1] This resource is used to study gene regulatory networks that link DNA sequence differences to corresponding differences in gene and protein expression and to variation in traits such as health and disease risk.

  5. Single-cell transcriptomics - Wikipedia

    en.wikipedia.org/wiki/Single-cell_transcriptomics

    Gene regulatory network inference is a technique that aims to construct a network, shown as a graph, in which the nodes represent the genes and edges indicate co-regulatory interactions. The method relies on the assumption that a strong statistical relationship between the expression of genes is an indication of a potential functional ...

  6. Gene co-expression network - Wikipedia

    en.wikipedia.org/wiki/Gene_co-expression_network

    The concept of gene co-expression networks was first introduced by Butte and Kohane in 1999 as relevance networks. [6] They gathered the measurement data of medical laboratory tests (e.g. hemoglobin level ) for a number of patients and they calculated the Pearson correlation between the results for each pair of tests and the pairs of tests which showed a correlation higher than a certain level ...

  7. Biological network - Wikipedia

    en.wikipedia.org/wiki/Biological_network

    The complete set of gene products and the interactions among them constitutes gene regulatory networks (GRN). GRNs regulate the levels of gene products within the cell and in-turn the cellular processes. GRNs are represented with genes and transcriptional factors as nodes and the relationship between them as edges.

  8. Global coordination level - Wikipedia

    en.wikipedia.org/wiki/Global_coordination_level

    However, inferring the precise pairwise interactions of the gene regulatory network remains challenging due to the large number of functional genes and the inherent stochasticity of these systems. [ 1 ] [ 2 ] Despite these challenges, certain features of the gene regulatory network can still be extracted without fully inferring all the ...

  9. Regulator gene - Wikipedia

    en.wikipedia.org/wiki/Regulator_gene

    Gene regulatory pathway. In genetics, a regulator gene, regulator, or regulatory gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences, which encode regulatory genes, are often at the five prime end (5') to the start site of transcription of the gene they regulate. In addition, these sequences ...
