Here the gEAR portal (gene Expression for Auditory Research portal) will be adapted to perform key gene comparison tasks for the HRP. The gEAR allows for graphic visualization of gene expression data in an intuitive way: multiple datasets can be displayed in a single page, all represented by cartoons and dynamically colored based on levels of gene expression. Additional features will be added through dedicated developer time to specifically serve the needs of the consortium, including additional dataset-specific graphics, tools for cross-dataset and cross-species comparisons, and intuitive integration of DNA structure and gene expression. Once the gEAR has been adapted for the HRP, all HRP members will be able to browse and interrogate the consortium data on a regular basis, allowing for computational identification of targets that lead to hair cell regeneration.
