Dr. Novotny leads a group that has been involved for 10 years in the development of glycomic and glycoproteomic molecular profiling techniques and their applications to disease biomarkers. The laboratory is expertly equipped with the latest mass-spectrometric instrumentation and separation technologies.

Collaborating with clinical investigators at the Simon Cancer Center (Indiana University Medical School, Indianapolis) and Georgetown University, the group has applied glycomic and glycoproteomic screening procedures based on mass spectrometry and capillary electrophoresis to find glycans and glycoproteins that distinguish sera from patients with breast, ovarian, prostate, hepatocellular, esophageal, and pancreatic cancers. While these translational science studies are relatively recent, several cancer-related investigations have been published that indicate considerable potential of analytical glycobiology in the early diagnosis and prognosis of cancer and its related conditions. Evaluations of quantitative glycomic patterns involve principal component analysis and statistical methods routinely accepted in the clinical laboratories. The chemical structures of putative glycan biomarkers are being primarily determined through tandem mass spectrometry.

The glycomic analyses used in this research laboratory environment are relatively fast, so that the investigators have been able to analyze hundreds of serum samples from diverse patient populations. In collaboration with Dr. Stephen Jacobson (microchip technologies) and Dr. Haixu Tang (bioinformatics) at Indiana University, the laboratory is working to transfer the knowledge obtained through biomarker mass-spectrometric identification to capillary electrophoresis microchip profiling with two objectives: faster acquisition of glycomic profiles for diagnostic and prognostic measurements; and resolution of certain glycan isomers that may be pertinent to cancer.

It is also essential that bioanalytical procedures utilize very small samples of human physiological fluids (e.g., microliter volumes of blood serum or pancreatic cyst fluids). The analytical results are correlated with the clinical information obtained through collaborations at the Simon Cancer Center and Hoosier Oncology Group in the Indiana University School of Medicine.

During the last 2 years, their studies have been supported by a Tumor Glycomics Laboratory grant from NCI and a center grant from the National Center for Research Resources. As a part of the Tumor Glycomics Laboratory grant, they have developed collaborations with Professor William Hancock (Northeastern University, Boston, MA) on the structural characterization of breast cancer glycoprotein biomarkers, as well as the application of glycomic profiling to lung cancer sera obtained from the patients before and after a surgical removal of tumors (Drs. Harvey Pass and Margaret Huflejt, New York University Medical School).
