The YEASTRACT database: a tool for the analysis of transcription regulatory associations in Saccharomyces cerevisiae
Miguel C. Teixeira,Pedro T. Monteiro,Pooja Jain,Sandra Tenreiro,Alexandra R. Fernandes,Nuno P. Mira,Marta Alenquer,Ana T. Freitas,Arlindo L. Oliveira,Isabel Sá-Correia +9 more
TL;DR: The YEAst Search for Transcriptional Regulators And Consensus Tracking (YEASTRACT; ) database is a repository of 12 346 regulatory associations between transcription factors and target genes, based on experimental evidence which was spread throughout 861 bibliographic references.
Journal ArticleDOI
The YEASTRACT database: an upgraded information system for the analysis of gene and genomic transcription regulation in Saccharomyces cerevisiae
Miguel C. Teixeira,Pedro T. Monteiro,Joana F. Guerreiro,Joana P. Gonçalves,Nuno P. Mira,Sandra C. dos Santos,Tânia R. Cabrito,Margarida Palma,Catarina Costa,Alexandre P. Francisco,Sara C. Madeira,Arlindo L. Oliveira,Ana T. Freitas,Isabel Sá-Correia +13 more
TL;DR: The YEASTRACT information system was revisited and new information was added on the experimental conditions in which those associations take place and on whether the TF is acting on its target genes as activator or repressor, allowing the selection of specific environmental conditions, experimental evidence or positive/negative regulatory effect.
Journal ArticleDOI
Current tools for the identification of miRNA genes and their targets
TL;DR: This article reviews the methods for miRNA gene finding and target identification that have been proposed in the last few years and identifies some problems that current approaches have not yet been able to overcome.
Journal ArticleDOI
YEASTRACT: providing a programmatic access to curated transcriptional regulatory associations in Saccharomyces cerevisiae through a web services interface
Dário Abdulrehman,Pedro T. Monteiro,Miguel C. Teixeira,Nuno P. Mira,Artur B. Lourenço,Sandra C. dos Santos,Tânia R. Cabrito,Alexandre P. Francisco,Sara C. Madeira,Ricardo Santos Aires,Arlindo L. Oliveira,Isabel Sá-Correia,Ana T. Freitas +12 more
TL;DR: The YEAst Search for Transcriptional Regulators And Consensus Tracking (YEASTRACT) information system, developed to support the analysis of transcription regulatory associations in Saccharomyces cerevisiae, was revisited and detailed information on the experimental evidences that sustain those associations was added.
Journal ArticleDOI
Degradability of linear polyolefins under natural weathering
Telmo Francisco Manfron Ojeda,Ana T. Freitas,Kátia Birck,Emilene Dalmolin,Rodrigo Josemar Seminoti Jacques,Fatima Menezes Bento,Flávio Anastácio de Oliveira Camargo +6 more
TL;DR: In this article, the real durability of olefin polymers may be much shorter than centuries, as in less than one year the mechanical properties of all samples decreased virtually to zero, as a consequence of severe oxidative degradation, that resulted in substantial reduction in molar mass accompanied by a significant increase in content of carbonyl groups.
