AI Article Synopsis

  • ExtraTrain is a comprehensive database focused on transcriptional regulation in prokaryotes, featuring information on 679,816 extragenic regions and regulatory proteins from bacteria and archaea.
  • The platform includes an interactive tool called Palinsight for exploring palindromic patterns in regulatory signals within user-defined extragenic regions.
  • ExtraTrain aims to be a community-driven resource, allowing researchers to contribute knowledge and maintain an extensive, curated repository of transcriptional regulation data, accessible at http://www.era7.com/ExtraTrain/.

Article Abstract

Background: Transcriptional regulation processes are the principal mechanisms of adaptation in prokaryotes. In these processes, the regulatory proteins and the regulatory DNA signals located in extragenic regions are the key elements involved. As all extragenic spaces are putative regulatory regions, ExtraTrain covers all extragenic regions of available genomes and regulatory proteins from bacteria and archaea included in the UniProt database.

Description: ExtraTrain provides integrated and easily manageable information for 679816 extragenic regions and for the genes delimiting each of them. In addition ExtraTrain supplies a tool to explore extragenic regions, named Palinsight, oriented to detect and search palindromic patterns. This interactive visual tool is totally integrated in the database, allowing the search for regulatory signals in user defined sets of extragenic regions. The 26046 regulatory proteins included in ExtraTrain belong to the families AraC/XylS, ArsR, AsnC, Cold shock domain, CRP-FNR, DeoR, GntR, IclR, LacI, LuxR, LysR, MarR, MerR, NtrC/Fis, OmpR and TetR. The database follows the InterPro criteria to define these families. The information about regulators includes manually curated sets of references specifically associated to regulator entries. In order to achieve a sustainable and maintainable knowledge database ExtraTrain is a platform open to the contribution of knowledge by the scientific community providing a system for the incorporation of textual knowledge.

Conclusion: ExtraTrain is a new database for exploring Extragenic regions and Transcriptional information in bacteria and archaea. ExtraTrain database is available at http://www.era7.com/ExtraTrain/.

Gene-based association analysis is a powerful tool for identifying genes that explain trait variability. An essential step of this analysis is a conditional analysis. It aims to eliminate the influence of SNPs outside the gene, which are in linkage disequilibrium with intragenic SNPs.

  • - Tumor mutational signatures are important in cancer research, but inconsistent methods make results unreliable; this study focused on colorectal cancer to assess how computational choices affect mutational analyses across various datasets.
  • - Analyzing 230 CRC cell lines and 152 patients, along with independent datasets from other cancer types, the researchers found that different algorithms and datasets led to significantly different mutational signature results.
  • - To help researchers standardize their analyses, the study introduced CoMSCER, a bioinformatics tool designed to streamline comparative mutational signature assessments in coding and non-coding regions of the genome.
