  • Mission Statement

    The mission of the Biostatistics and Bioinformatics Shared Resource Facility (BCBR SRF) is to provide expertise and a variety of services to basic and clinical investigators of the Markey Cancer Center (MCC) doing basic, pre-clinical, and clinical research.

    The Biostatistics and Bioinformatics Shared Resource Facility (BB SRF) is a cancer center-managed shared resource that plays a key collaborative role in providing scientific and statistical input across the entire spectrum of cancer research being performed at the Markey Cancer Center (MCC). The mission of the BB SRF is to apply statistical principles to enhance the execution of scientific research through collaborative interactions with MCC members. To this end, our primary goal is to provide a comprehensive, centralized, and accessible biostatistics and bioinformatics support infrastructure to support all phases of cancer studies, including study development, implementation, and post-study analyses.

  • Bioinformatics Section

    bio

    The Bioinformatics Section of the Biostatistics and Bioinformatics Shared Resource Facility (BB SRF) aims to build and maintain robust and state-of-the-art analysis pipelines for analyzing, interpreting, and visualization of large-scale genomic, epigenomic, transcriptomic and metabolomic data generated by the Markey Cancer Center's (MCC) cancer research experiments. While these pipelines can be used for general purpose bioinformatics applications, they are specifically tailored to reveal mutations and complex behaviors of cancer genomes. We work closely with and provide custom bioinformatics solutions for MCC investigators. Our current services focus on the following areas. New services will be added depending on demand.

    • Next Generation Sequencing Data Analysis. The Bioinformatics Section has developed comprehensive pipelines to process and analyze data from:
      • Whole-genome or whole-exome sequencing.
      • RNA-seq.
      • ChIP-seq.
      • Whole-genome bisulfite sequencing.
    • Metabolomics Data Analysis. The Bioinformatics Section provides informatics support for raw and intermediate data analysis of metabolomics datasets, especially stable isotope-resolved metabolomics datasets. Results of these analyses can feed into other biostatistical analyses provided by the section. Custom downstream metabolic modeling and relative flux analyses can be provided on a limited basis.
    • Microarray Data Analysis. The Bioinformatics Section has developed a pipeline for microarray data processing and analysis, including data normalization, quality assessment, differential expression identification and visualization, and pathway/functional analysis.
    • Integrative Analysis of Multiple Omics Datasets. The Bioinformatics Section provides bioinformatics support to analyze the interaction or correlation across multiple genomic data. Some examples include the integrative analysis of DNA-methylation data and RNA-seq data to look at the regulation of global gene expression, the detection of aberrant transcripts using both DNA-seq and RNA-seq data, and correlation analysis between RNA-seq and existing microarray data. The section also provides support for soft multi-omics integration using CategoryCompare, which provides integration at the level of annotations across omics datasets. Please contact us for more details.
    • Genomic Data Mining. The section uses genomic data repositories such as GEO, Oncomine, and TCGA to correlate genomic data from specific gene(s) of interest with clinical outcomes.
    • Other Large-Scale Genomic Data Analysis. The section provides bioinformatics support for other genomic experimental platforms such as the NanoString nCounter system.
    • Grant-writing Support. The section will help investigators with genomic study design, sample size/power calculation, data analysis plans, and writing bioinformatics sections.
    • Training and Consultation. It is important to establish a rapport and dialogue between biomedical researchers, bioinformaticians and computational biologists. The Bioinformatics Section works with investigators to establish new data analysis pipelines. The section's personnel host training/consultation/courses/lectures on bioinformatics study designs, tools, resources and databases. New services will be advertised as they become available.

    Storage and Computational Resources

      The BB SRF is adequately equipped with state-of- the art computing resources to support all levels of research, particularly clinical and bioinformatics studies. Computing resources for the BB SRF and other MCC facilities are centrally coordinated by the MCC Cancer Research Informatics Shared Resource Facility (CRI SRF). The CRI SRF also takes the lead in coordinating resources from the university’s Center for Computational Sciences (CCS, see below) to support big data initiatives. The BB SRF leverages MCC resources and University of Kentucky campus-wide resources to ensure optimal and secure infrastructure for computational and analytical activities.

      The CCS offers a Dell HPC cluster (supercomputer) rated at just over 140 Teraflops, consisting of general purpose CPUs, highly parallel GPUs, large memory nodes, a high speed Infiniband network, and high-performance file system.

    • Data Management Section

      Contact

      Goal: The mission of the Data Management Section (DMS) is to ensure adequate and standardized data management support for research projects, in particular, those emanating from the four Research Programs at the Markey Cancer Center (MCC).

      Summary of Services:

        The DMS provides services during all phases of studies, including planning execution and analyses.

        • Planning: Services include assistance in eCRF/questionnaire development, assurance of sufficient linkage between all data, creation of automated alerts for interim analyses and safety stops and interaction with MCC's Cancer Research Informatics Shared Resource Facility (CRI SRF) for informatics technology support.
        • Execution: Data will be exported periodically on a pre-determined schedule, data validation scripts will be run on the data and queries sent for clarification. Enrollment and quality reports will be created.
        • Analyses: At the end of data collection, a final data validation will be performed.
