Genevestigator

Genevestigator is an online platform enabling researchers to globally explore public and proprietary expression data for research and clinical applications. It's a software tool developed for biologists and medical researchers to identify novel targets and biomarkers, characterise and prioritise candidate genes, and in general to understand which factors cause genes to be regulated. Specifically, gene expression is visualised in the context of tissues, stimuli, drug treatments, diseases, or genetic modifications. Results are processed from a very large database of manually curated and quality-controlled microarrays and RNAseq samples from a large variety of tissues and conditions. Currently, data is available for human, mouse, rat, monkey, pig, dog, drosophila, arabidopsis, barley, rice, wheat, maize, medicago, tomato, tobacco, moss and soybean.

Genevestigator was started in January 2004 by scientists from ETH Zurich and is currently developed and commercialized by Nebion AG.

Tool for biologists and medical researchers

More than 50,000 scientists have registered for GENEVESTIGATOR (mostly biologists) from the animal and plant research areas. Its tools have been used in molecular biology, toxicogenomics, and biomarker discovery/validation. As of 2018, its original articles have been cited more than 3,500 times by researchers using the tools.

Three tool sets, each containing several tools, are available:

• CONDITION SEARCH tools: find conditions that are relevant for your genes of interest
• GENE SEARCH tools: find genes that are specifically expressed in conditions of interest
• SIMILARITY SEARCH tools: find genes that are similar within a data space.
