Applied Systems Biology Core

Matthias Kretzler, MD
ASBC Director

The emerging field of systems biology aims to integrate the constantly growing amount of complex biological information to provide a comprehensive description of regulatory events. This approach has been greatly facilitated by the rapid development of molecular medicine allowing the generation of large-scale data sets from small-scale patient samples.

Systems genetics approaches can also be employed to define regulatory dependencies between genotypic risk, molecular profiles, and phenotypic parameters.

The Applied Systems Biology Core (ASBC) helps Research Investigators to link the large-scale data sets generated by ongoing research projects in their specific research interest. They are then able to link the clinical, genetic, and molecular information with the specific mechanism of renal function and failure that are of interest to the investigator.

Main Objectives of the ASBC: Empowering the renal community to employ genome-scale information to:

The ASBC is comprised of 3 different services.

 

Service 1: Interactive shared data mining services:

  • Introduction to and training in system biology tools
  • Genome scale data mapping and analyses (transcripts, proteins, metabolites, pathways)
  • Integration of multi-omic data sets to identify cross cutting mechanisms 

 

Service 2: Development and support of web based search engine: 

 

  • User-friendly tool to link gene expression with renal function and failure
  • No deep bioinformatics skills necessary
  • Fast results with direct human relevance
  • More data at your fingertips
    • Supplementary clinical information from study authors
    • Standardized clinical metadata

Service 3: Support for study specific data analysis platforms

  • Cohort specific data mining tools using tranSMART for dynamic data mining across a wide range of data sets
  • CPROBE-specific tranSMART instance for the Kidney Center

 

When using any core services, users agree to cite the George M. O’Brien Michigan Kidney Translational Core Center, funded by NIH/NIDDK grant 2P30-DK-081943 in any publications and/or presentations resulting from the use of these core services.
