Chordoma research is led by a comprehensive team including Gary Gallia, M.D., director of the Neurosurgery Skull Base Tumor Center. The laboratory focuses on developing new therapies for brain and skull base tumors, and has established the first primary skull base chordoma xenograft mouse model. The team is also exploring high throughput drug screening using the chordoma model, and the molecular pathways responsible for tumor maintenance and growth.

Dr. Borahay's lab focuses on understanding pathobiology, developing novel treatments, and carrying out high quality clinical trials for common gynecologic problems with a special focus on uterine fibroids. Our lab also investigates the causes and novel treatments for menstrual disorders such as heavy and irregular periods. In addition, Dr. Borahay’s team explores innovative approaches to minimally invasive gynecologic surgery, focusing on outpatient procedures with less pain and faster recovery times.

The Pardoll Lab focuses on the regulation of antigen-specific T cell responses and studies approaches to modify these responses for immunotherapy. Pardoll has a particular interest in cancer immunology and his lab’s studies on basic immunologic mechanisms have led to the development and design of a number of cancer vaccines and discovery of key checkpoint ligands and receptors, such as PD-L2, LAG-3 and neuritin, many of which are being targeted clinically. Our primary pursuits are discovering and elucidating new molecules that regulate immune responses, investigating the biology of regulatory T cells, and better understanding the specific biochemical signatures that allow a patient’s T cells to selectively target cancer cells.

The Shenderov Lab focuses on the elucidation of the mechanisms of immune response and resistance to immunotherapy in Prostate Cancer. This has led to clinical and basic research investigating the presumptive checkpoint inhibitor B7-H3. In pursuit of understanding biomarkers or resistance and response, and regulatory molecules of immune response, we utilize artificial intelligence, immunogenomics, and spatial proteomics and transcriptomics in the laboratory and at the bedside using clinical trial correlative samples.

Research in the Mihail Zilbermint Lab focuses on diabetes, adrenal disease and thyroid disease. Recent areas of focus include pseudohypoaldosteronism type 1 related to novel variants of SCNN1B gene, genetic variance in the ARMC5 gene in primary macronodular adrenocortical hyperplasia and hyperaldosteronism due to de novo KCNJ5 mutation.

Directed by Alan R. Cohen, M.D., Carson-Spiro Professor of Neurosurgery, Oncology and Pediatrics, the laboratory is focused on developing novel instruments and approaches to enhance the safety and efficacy of neurosurgical procedures. Current investigations include work in microsurgery, endoscopy, image guidance and robotic surgery. A cadaveric skills lab offers training in neurosurgical techniques.

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.

The Amit Pahwa Lab conducts research on a variety of topics within internal medicine. Our most recent studies have explored misanalysis of urinalysis results, urinary fractional excretion indices in the evaluation of acute kidney injury and nocturnal enuresis as a risk factor for falls in older women. We also investigate cancer diagnostics and treatments. In this area, our recent research has included studying cutaneous shave biopsies for diagnosing primary colonic adenocarcinoma as well as growth inhibition and apoptosis in human brain tumor cell lines using selenium.

Dr. Meltzer is an internationally renowned leader in the molecular pathobiology of gastrointestinal malignancy and premalignancy. He invented molecular methods to detect loss of heterozygosity in tiny biopsies, triggering an avalanche of research on precancerous lesions. He was the first to comprehensively study coding region microsatellite instability, leading to the identification of several important tumor suppressor genes. He performed several groundbreaking genomic, epigenomic and bioinformatic studies of esophageal and colonic neoplasms, shifting the GI research paradigm toward genome-wide approaches. He directed an ambitious nationwide validation study of DNA methylation-based biomarkers for the prediction of neoplastic progression in Barrett’s esophagus. Dr. Meltzer founded and led the Aerodigestive Cancer and Biomarker Interdisciplinary Programs at the University of Maryland, also becoming associate director for core sciences at that school’s Cancer Center. He currently holds an endowed professorship and is the director of GI biomarker research at Johns Hopkins. The laboratory group focuses its efforts on the molecular genetics of gastrointestinal cancers and premalignant lesions, as well as on translational research to improve early detection, prognostic evaluation, and treatment of these conditions. Below, some examples of this work are described.

The goal of the Johns Hopkins Brain Cancer Biology and Therapy Laboratory is to locate the genetic and genomic changes that lead to brain cancer. These molecular changes are evaluated for their potential as therapeutic targets and are often mutated genes, or genes that are over-expressed during the development of a brain cancer. The brain cancers that the Riggins Laboratory studies are medulloblastomas and glioblastomas. Medulloblastomas are the most common malignant brain tumor for children and glioblastomas are the most common malignant brain tumor for adults. Both tumors are difficult to treat, and new therapies are urgently needed for these cancers. Our laboratory uses large-scale genomic approaches to locate and analyze the genes that are mutated during brain cancer development. The technologies we now employ are capable of searching nearly all of a cancer genome for molecular alterations that can lead to cancer. The new molecular targets for cancer therapy are first located by large scale gene expression analysis, whole-genome scans for altered gene copy number and high throughput sequence analysis of cancer genomes. The alterations we find are then studied in-depth to determine how they contribute to the development of cancer, whether it is promoting tumor growth, enhancing the ability for the cancer to invade into normal tissue, or preventing the various fail-safe mechanisms programmed into our cells.
