• Description: CanProVar is designed to store and display single amino acid alterations including both germline and somatic variations in the human proteome, especially those related to the genesis or development of human cancer based on the published literatures. Cancer-related variations and conrresponding annotations can be queried through the web-interface using Protein IDs in the Ensembl, IPI, RefSeq, and Uniport/Swiss-Prot databases or gene names and Entrez gene IDs. Fasta files with variation information are also available for download.

  • Description: CEA (Complex-Enrichment Analysis) uses a protein interaction network-assisted approach to improve protein identification in shotgun proteomics. A large proportion of possible proteins are eliminated as a result of insufficient experimental evidence in shotgun proteomics data analysis. CEA can be used to rescue the eliminated proteins based on a simple assumption: possible proteins are more likely to be present in the original sample if they exist in a complex enriched with confidently identified proteins. In various data sets tested, CEA increased protein identificaion by 10-30% with an estimated accuracy of 85%.

  • Description: The goal of Gene List Automatically Derived For You (GLAD4U) is to implement an algorithm searching the scientific literature (Pubmed) to retrieve the list of publications corresponding to a user’s query. The algorithm will then translate the list of publications into a list of genes referenced in these publications. The last step is to present the user with the list of prioritized genes, from the most to the least referenced genes within the search space.

  • Description: Network analysis plays an important role in systems biology. However, network analysis algorithms are usually computationally intensive. Mordern General Purpose computation on Graphics Processing Units (GPGPUs) provides a cost-effective platform for this type of applications. We have initiated a project to enable fast network analysis on GPUs. The first verison of the software package gpu-fan (GPU-based Fast Analysis of Networks) includes methods for computing four shortest path-based centrality metrics on NVIDIA’s CUDA platform. Speedup of 10x ~ 50x was observed for simulated scale-free networks and real world protein interaction and gene co-expression networks.

  • Description: NetSAM (Network Seriation and Modularization) is an R package that takes an edge-list representation of a network as an input and generates files that can be used as an input for the one-dimensional network visualization tool NetGestalt ( or other network analysis. NetSAM uses random walk distance-based hierarchical clustering to identify the hierarchical modules of the network (network modularization) and then uses the optimal leaf ordering (OLO) method to optimize the one-dimensional ordering of the genes in each module by minimizing the sum of the pair-wise random walk distance of adjacent genes in the ordering (network seriation).

  • Description: NetWalker takes a network and a list of nodes from the network as input and calculates steady-state probabilities (final scores) for all nodes in the network based on the random walk technology. Statistical analysis is implemented to evaluate the significance of the final scores. Specifically, for each node, a global p value is calculated to evaluate the overall significance of the node with regard to the input nodes, while a local p value is calculated to ensure that the significance is not simply due to network topology.
