  • 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.

    Research Areas: optical imaging, molecular characterization of tumor tissue, bioinformatics, molecular oncology, biostatistics, probe development, molecular characterization of cells, cancer imaging

  • Ivan Borrello Lab

    The Ivan Borrello Lab focuses on the development of a novel approach of adoptive T cell therapy utilizing marrow-infiltrating lymphocytes (MILs) as a more tumor-specific T cell approach. This has led to establishing the first adoptive T cell trials at Johns Hopkins and an exploration of this approach in other diseases, including nonhematologic malignancies. The lab also examines strategies for treating minimal residual disease (MRD) in myeloma with the combination of immune modulation and whole cell-based vaccines.

  • Jinyuan Zhou Lab

    Dr. Zhou's research focuses on developing new in vivo MRI and MRS methodologies to study brain function and disease. His most recent work includes absolute quantification of cerebral blood flow, quantification of functional MRI, high-resolution diffusion tensor imaging (DTI), magnetization transfer mechanism, development of chemical exchange saturation transfer (CEST) technology, brain pH MR imaging, and tissue protein MR imaging. Notably, Dr. Zhou and his colleagues invented the amide proton transfer (APT) approach for brain pH imaging and tumor protein imaging. His initial paper on brain pH imaging was published in Nature Medicine in 2003 and his most recent paper on tumor treatment effects was published in Nature Medicine in 2011. A major part of his current research is the pre-clinical and clinical imaging of brain tumors, strokes, and other neurologic disorders using the APT and other novel MRI techniques. The overall goal is to achieve the MRI contrast at the protein and peptide ...level without injection of exogenous agents and improve the diagnostic capability of MRI and the patient outcomes. view more

  • John T. Isaacs Laboratory

    While there has been an explosion of knowledge about human carcinogenesis over the last 2 decades, unfortunately, this has not translated into the development of effective therapies for either preventing or treating the common human cancers. The goal of the Isaacs’ lab is to change this situation by translating theory into therapy for solid malignancies, particularly Prostate cancer. Presently, a series of drugs discovered in the Isaacs’ lab are undergoing clinical trials in patients with metastatic cancer.

    The ongoing drug discovery in the lab continues to focus upon developing agents to eliminate the cancer initiating stem cells within metastatic sites of cancer. To do this, a variety of bacterial and natural product toxins are being chemically modified to produce “prodrugs” whose cytotoxicity is selectively activated by proteases produced in high levels only by cancer cells or tumor associated blood vessel cells. In this way, these prodrugs can be given systemically to metastati...c patients without un-acceptable toxicity to the host while being selectively activated to potent killing molecules within metastatic sites of cancer.

    Such a “Trojan Horse” approach is also being developed using allogeneic bone marrow derived Mesenchymal Stem cells which are genetically engineered to secrete “prodrugs” so that when they are infused into the patient, they selectively “home” to sites of cancers where the appropriate enzymatic activity is present to liberate the killing toxin sterilizing the cancer “neighborhood”.

  • Jonathan D. Powell Lab

    The program in cancer and immunometabolism seeks to both understand and target metabolic programming in both the cancer and immune cells in order to enhance immunotherapy for cancer. To this end, in collaboration in with the Johns Hopkins Drug Discovery Program, the lab is developing novel agents that target tumor glutamine metabolism. These compounds not only inhibit tumor growth but render tumors more susceptible to immunotherapies such as checkpoint blockade and adoptive cellular therapy. Additionally, the group is dissecting key metabolic pathways that regulate immune cell activation, differentiation and function. By targeting these pathways, they are discovering new ways to both enhance the efficacy of antitumor T cells as well as inhibit T regulatory cells and myeloid-derived suppressor cells.

  • Kenneth W. Kinzler Laboratory

    Dr. Kinzler’s laboratory has focused on the genetics of human cancer. They have identified a variety of genetic mutations that underlie cancer, including mutations of the APC pathway that appear to initiate the majority of colorectal cancers and IDH1/2 mutations that underlying many gliomas. In addition, they have developed a variety of powerful tools for analysis of expression and genetic alterations in cancer.
    Most recently, they have pioneered integrated whole genome analyses of human cancers through expression, copy number, and mutational analyses of all the coding genes in several human cancer types including colorectal, breast, pancreatic and brain. The identification of genetic differences between normal and tumor tissues provide new therapeutic targets, new opportunities for the early diagnosis of cancer, and important insights into the neoplastic process.

  • Lei Zheng Lab

    Zheng’s research focuses on two R01-funded projects; first, the group has developed a pancreatic cancer immunotherapy research program on a neoadjuvant therapy platform as well as a number of preclinical models of pancreatic cancer for developing innovative immunotherapy strategies. The group has applied the knowledge gained from pancreatic cancer immune-based therapies to the development of a colorectal cancer GVAX vaccine. Second, the group is aimed at understanding the mechanistic roles of the tumor microenvironment in cancer development and metastasis and identifying new targets for pancreatic cancer therapies by dissecting the tumor microenvironment of pancreatic cancer.

  • 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.

    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.

  • Mohamed Farah Lab

    The Mohamed Farah Lab studies axonal regeneration in the peripheral nervous system. We've found that genetic deletion and pharmacological inhibition of beta-amyloid cleaving enzyme (BACE1) markedly accelerate axonal regeneration in the injured peripheral nerves of mice. We postulate that accelerated nerve regeneration is due to blockade of BACE1 cleavage of two different BACE1 substrates. The two candidate substrates are the amyloid precursor protein (APP) in axons and tumor necrosis factor receptor 1 (TNFR1) on macrophages, which infiltrate injured nerves and clear the inhibitory myelin debris. In the coming years, we will systematically explore genetic manipulations of these two substrates in regard to accelerated axonal regeneration and rapid myelin debris removal seen in BACE1 KO mice. We also study axonal sprouting and regeneration in motor neuron disease models.
