-
In-vivo Cellular and Molecular Imaging Center
The In-vivo Cellular and Molecular Imaging Center conducts multidisciplinary research on cellular and molecular imaging related to cancer. We provide resources, such as consultation on biostatistics and bioinformatics and optical imaging and probe development, to understand and effectively treat cancer. Our molecular oncology experts consult on preclinical studies, use of human tissues, interpretation of data and molecular characterization of cells and tumor tissue. -
The Pathak Lab
The Pathak lab is within the Division of Cancer Imaging Research in the Department of Radiology and Radiological Science. We develop novel imaging methods, computational models and visualization tools to ‘make visible’ critical aspects of cancer, stroke and neurobiology. Our research broadly encompasses the following areas: Functional and Molecular Imaging; Clinical Biomarker Development; Image-based Systems Biology and Visualization and Computational Tools. We are dedicated to mentoring the next generation of imagers, biomedical engineers and visualizers. Additional information can be found at www.pathaklab.org or by emailing Dr. Pathak. -
Mass Spectrometry Core
The Mass Spectrometry Core identifies and quantifies proteins that change expression in well-characterized protein fractions from cancerous cells or tissues. This includes identifying and quantifying changes in binding partners and post-translational modifications. Column chromatography and gel electrophoresis-based one and two-dimensional separations of protein complexes coupled to mass spectrometry are used. Techniques such as difference gel electrophoresis (DIGE), isobaric tag for relative and absolute quantitation (iTRAQ) and 18O-labeling as well as non-labeling methods (MudPit, multi-dimensional protein identification technology) are available for quantifying relative differences in protein expression and post-translational modifications. We developed methods to detect post-translational modifications such as LCMS methods to accurately determine the intact mass of proteins, selective fluorescent labeling of S-nitrosothiols (S-FLOS) to detect nitrosated cysteines in proteins, and ion mapping methods to map post-translational modifications that produce a signature mass or mass difference when the modified peptide is fragmented. -
Marie-France Penet Lab
The Penet lab is within the Division of Cancer Imaging Research in the Department of Radiology and Radiological Science. The lab research focuses on using multimodal imaging techniques to better understand the microenvironment and improve cancer early detection, especially in ovarian cancer. By combining MRI, MRS and optical imaging, we are studying the tumor microenvironment to understand the role of hypoxia, tumor vascularization, macromolecular transport and tumor metabolism in tumor progression, metastasis and ascites formation in orthotopic models of cancer. We also are studying the role of tumor-associated macrophages in tumor progression. -
Michael Matunis Lab
Research in the Michael Matunis Lab focuses on the SUMO family of small ubiquitin-related proteins. We study the covalent conjugation of SUMOs to other cellular proteins, which regulates numerous processes needed for cell growth and differentiation, and which, when defective, can lead to conditions such as cancer, neurodegenerative disease and diabetes. -
Marcia Canto Lab
Research interests in the Marcia Canto Lab include pancreatic neoplasms, Barrett’s esophagus and endomicroscopy. We are also interested in the use of endoscopic ultrasound to identify early-stage pancreatic cancer and its precursors. -
Michael Goggins Lab
The Michael Goggins Lab performs basic, translational, and clinical research on pancreatic cancer. -
Spinal Oncology Lab
The bony skeleton is one of the most common sites of metastatic spread of cancer and a significant source of morbidity in cancer patients, causing pain and pathological fracture, impaired ambulatory ability and poorer quality of life.
In our continuous investigation of the mechanism of metastasis in spine tumors and of developing animal models and treatments, our team seeks to understand how cancer cells metastasize to the bony spine.
Our laboratory develops novel techniques to evaluate our animal models of metastatic spine disease. -
Srinivasan Yegnasubramanian Lab
Dr. Yegnasubramanian directs a Laboratory of Cancer Molecular Genetics and Epigenetics at the Sidney Kimmel Comprehensive Cancer Center (SKCCC), and is also the Director of the SKCCC Next Generation Sequencing Center. Our lab research is focused on understanding the complex interplay between genetic and epigenetic alterations in carcinogenesis and disease progression, and to exploit this understanding in developing novel biomarkers for diagnosis and risk stratification as well as in identifying targets for therapeutic intervention. -
The Sfanos Lab
The Sfanos Lab studies the cellular and molecular pathology of prostate disease at the Johns Hopkins University School of Medicine. We are specifically interested in agents that may lead to chronic inflammation in the prostate, such as bacterial infections and prostatic concretions called corpora amylacea. Our ongoing studies are aimed at understanding the influence of prostate infections and inflammation on prostate disease including prostate cancer and benign prostatic hyperplasia (BPH). The laboratory also focuses on the influence of the microbiome on prostate disease development, progression, and/or resistance to therapy.
