The role of lipid metabolism in neuronal senescence
FEBS Open Bio, EarlyView.Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

FEBS Open Bio, EarlyView.A tri‐culture of iPSC‐derived neurons, astrocytes, and microglia treated with ferroptosis inducers as an Induced ferroptosis model was characterized by scRNA‐seq, cell survival, and cytokine release assays. This analysis revealed diverse microglial transcriptomic changes, indicating that the system captures key aspects of the complex cellular ...

Community-based gene structure annotation
Trends in Plant Science, 2005Uncertainty and inconsistency of gene structure annotation remain limitations on research in the genome era, frustrating both biologists and bioinformaticians, who have to sort out annotation errors for their genes of interest or to generate trustworthy datasets for algorithmic development. It is unrealistic to hope for better software solutions in the

Complexity of automated gene annotation
Biosystems, 2011Integration of high-throughput data with functional annotation by graph-theoretic methods has been postulated as promising way to unravel the function of unannotated genes. Here, we first review the existing graph-theoretic approaches for automated gene function annotation and classify them into two categories with respect to their relation to two ...

Annotating Noncoding RNA Genes
Annual Review of Genomics and Human Genetics, 2007Noncoding RNA genes produce a functional RNA product rather than a translated protein. More than 1500 homologs of known “classical” RNA genes can be annotated in the human genome sequence, and automatic homology-based methods predict up to 5000 related sequences.

Gene Annotation: Prediction and Testing
Annual Review of Genomics and Human Genetics, 2003Fifty years after the publication of DNA structure, the whole human genome sequence will be officially finished. This achievement marks the beginning of the task to catalogue every human gene and identify each of their function expression patterns. Currently, researchers estimate that there are about 30,000 human genes and approximately 70% of these ...

Gene annotation used to refer to the prediction and annotation of a coding transcript on a region of the genome, but as the complexity of the functional features on the genome increases, users require prediction of noncoding RNAs, alternatively spliced transcripts, pseudogenes, and conserved elements. Eight years after the initial draft sequence of the

Methods for Gene Ontology Annotation
2007The Gene Ontology (GO) is an established dynamic and structured vocabulary that has been successfully used in gene and protein annotation. Designed by biologists to improve data integration, GO attempts to replace the multiple nomenclatures used by specialised and large biological knowledgebases.

Bioinformatics: Databasing and Gene Annotation
2008"Omics" experiments amass large amounts of data requiring integration of several data sources for data interpretation. For instance, microarray, metabolomic, and proteomic experiments may at most yield a list of active genes, metabolites, or proteins, respectively. More generally, the experiments yield active features that represent subsequences of the

Gene Structure Annotation at PlantGDB
2007The accurate identification of exons and introns that comprise a complete plant gene structure can be a time-consuming and challenging task. Novel Web-based tools facilitate the process by providing a convenient interface to current transcript evidence, and portals to relevant bioinformatics software.
