LINT‐Web: A Web‐Based Lipidomic Data Mining Tool Using Intra‐Omic Integrative Correlation Strategy. Issue 9 (31st July 2021) - Li, Fengsheng
Abstract: Lipidomics is a younger member of the "omics" family. It aims to profile lipidome alterations occurring in biological systems. Similar to the other "omics", lipidomic data is highly dimensional and contains a massive amount of information awaiting deciphering and data mining. Currently, the available bioinformatic tools targeting lipidomic data processing and lipid pathway analysis are limited. A few tools designed for lipidomic analysis perform only basic statistical analyses, and lipid pathway analyses rely heavily on public databases (KEGG, Reactome, and HMDB). Due to the inadequate understanding of lipid signaling and metabolism, the use of public databases for lipid pathway analysis can be biased and misleading. Instead of using public databases to interpret lipidomic ontology, the authors introduce an intra‐omic integrative correlation strategy for lipidomic data mining. Such an intra‐omic strategy allows researchers to unscramble and predict lipid biological functions from correlated genomic ontological results using statistical approaches. To simplify and improve the lipidomic data processing experience, they designed an interactive web‐based tool: LINT‐web (http://www.lintwebomics.info/ ) to perform the intra‐omic analysis strategy, and validated the functions of LINT‐web using two biological systems. Users without sophisticated statistical experience can easily process lipidomic datasets and predict the potential lipid biological functions using LINT‐web. Abstract : LINT‐web is an interactive website designed for lipidomic data processing, which applies integrative intra‐omic strategy to data mining the lipid ontology. The website takes lipidomic results produced by mass spectrometry and performs basic statistical analyses, integrative intra‐omic correlation, and ontology network construction. The advantages of integrative intra‐omic analysis on novel lipid function discovery are evaluated by different biological systems.
