The Pennington Biomedical Research Center has developed a state-of-the-art high throughput proteomics facility. The proteomics facility allows researchers to measure the relative abundance of proteins within a cell or tissue, determine the subcellular localization of proteins, examine the extent of protein modification, and identify proteins which are secreted from cells. The technology is built around high resolution analytical 2-dimensional gel electrophoresis using multiple gel size formats (7 - 18 cm IEF gels and corresponding SDS-gels) and multiple staining protocols (silver, sypro ruby, western blot with detection). Sensitive imaging techniques coupled with sophisticated imaging and analysis software provides capabilities for spot matching between multiple gels, spot quantitation, the preparation of an annotated “Master Gel, and routine statistical analysis.
The facility also provides state-of-the-art high throughput identification of peptides and proteins. Automated spot picking from preparative 2d-gel electrophoresis and automated in-gel protein digestion, peptide extraction, and MALDI slide spotting facilitates sample preparation for protein identification. A MALDI-TOF mass spectrometer is used to identify proteins through peptide mass fingerprinting. A Q-TOF mass spectrometer is used to verify protein identification through multiple partial peptide sequencing. An integrated data management system provides tracking of all samples through the process, annotation of samples with experimental conditions, and integration with external public proteomic and metabolic databases. |

Faculty: Lilian Levitan, Ph.D.
The main goal of the metabolic chambers core is to perform and provide reliable and reproducible assessments of energy expenditure and substrate oxidation in humans. The technique used for these measurements is indirect calorimetry.
Two types of equipment for these measurements are available at the Pennington Center. Metabolic carts (Deltatrac II metabolic monitors) are used for measurements under resting conditions. The Center has eight of those devices, which are used for the assessment of energy metabolism under resting conditions such as resting metabolic rate (RMR) and the acute effects of possible thermogenic stimuli such as a meal or pharmaceutical and herbal compounds. In addition, the metabolic carts are used during insulin clamp studies to calculate glucose oxidation. The carts use the ventilated hood technique which makes measurements over several hours possible. During 2004 and 2005, we performed approximately 1700 measurements for a variety of studies.
For the measurements of energy expenditure and substrate oxidation on a 24-hour basis whole room indirect calorimeters are used. The Center has two metabolic chambers, (10 feet x 12 feet x 8 feet). Because studies include periods of 24 hours up to 7 consecutive days in the chambers, they are designed to provide a pleasant environment to our study participants. During the last few years, the programming of our chambers was updated to allow for minute to minute data output, making the chambers not only useful for the measurements of 24-hour energy metabolism but also for the assessments of acute changes. During 2004 and 2005 we performed close to 450 measurements of 24H energy expenditure for several studies. |

As the name implies, the Biostatistics and Data Management Core has two primary functions. Through collaboration with Center scientists, our biostatisticians provide statistical support for clinical and non-clinical studies conducted at the Center. And, our data management team, consisting of systems analysts and applications programmers, is responsible for implementation and maintenance of the Central Clinical Database, the institution’s primary archive of clinical research data.
Biostatistical functions of the Core include general statistical consultation, experimental design consultation, sample size determination and power analyses, data analysis and interpretation, and reporting of results of clinical studies. In addition, our biostatisticians pursue independent research in statistical theory and methods related to the planning and conduct of clinical trials.
The database management team’s responsibilities center on the prime mission of creating and maintaining the unified central database for clinical data at PBRC. In addition, our programmers are charged with development of the specialized applications that are used to collect clinical data from diverse sources throughout the institution. Also, this group has responsibility for the continuing development of CDA, an application that provides authorized users a web-based portal to the clinical database. |
