Mark Sleeman, Professor of Physiology, Monash University, Australia John Harris, Associate Professor of Medicine, UMASS Medical School Zhen Jiang, Associate Professor of Pharmacology and Medicine, Boston University Vishu Puri, Professor of Biomedical Sciences, Ohio University Olga Gupta, Assistant Professor of Pediatrics and Medicine, University of Texas Southwestern Medical Center Tim Fitzgibbons, Assistant Professor of Medicine, UMASS Medical School Myriam Aouadi, Assistant Professor, Integrated Cardio Metabolic Centre, Karolinska Institute Adilson Guilherme, Associate Professor, University of Massachusetts Medical School Our laboratory currently offers graduate student Rotation Projects (examples below and others available) and Thesis Research Projects for students following a rotation: Developing CRISPR technology for gene editing in adipocytes: Adipocytes function as master regulators of whole body metabolism and deletions of specific adipocyte genes in knockout mice promote dramatic improvements in glucose tolerance and insulin sensitivity in diabetic models. Thus the ability to direct gene editing in adipocytes in vivo has great potential in developing therapeutic strategies for obesity, type 2 diabetes and cardiovascular complications. Alternatively, an ex vivo approach is also feasible since adipose cells can be genetically altered in vitro prior to implantation into mice with beneficial effects. Such projects are designed to be performed in collaboration with other Czech lab members with the goal of specifically deleting or editing genes in adipose depots that drive increases in fatty acid oxidation, energy expenditure and systemic metabolic activity. Exciting preliminary data at the “proof of principle” stage has been achieved and this project is designed to focus on specific genes of high interest for therapeutics. Signaling by the lipogenesis pathway through Acetyl CoA: A major function of adipocytes is to store calories as triglyceride, in part through the process of fatty acid synthesis (lipogenesis). This metabolic pathway involves a number of metabolites including Acetyl CoA, which is also a substrate for acetylation reactions that modify proteins such as histones. Thus metabolic flux through adipocyte lipogenesis may also function as a signaling pathway to the nucleus to modulate transcription via levels of Acetyl CoA that accumulate during this process. This rotation project is designed to test this idea at the molecular level by monitoring histone acetylations and resultant transcriptional events during changes in Acetyl CoA levels caused by altering physiological conditions such as exercise, obesity and diabetes. If this concept is correct, the project could lead to developing therapeutic strategies for metabolic disease based on targeting lipogenic enzymes.

Rotations: Targeting the IFN-?-chemokine axis for treatment of vitiligo: We are using our newly developed mouse model and human tissues from patients with vitiligo to identify the cytokines and chemokines that are expressed within the depigmenting skin and which skin cells produce them. We are using genetically modified mouse strains (knockouts, conditional knockouts, fluorescent reporter strains), and cytokine and chemokine neutralizing antibodies to identify the key proteins required for disease. This data will permit us to rationally develop and test new therapeutic agents. Understanding the proinflammatory signals generated by melanocytes under cellular stress. Melanocytes from vitiligo patients have intrinsic abnormalities, including cellular stress evidenced by increased production of reactive oxygen species (ROS) and activation of the unfolded protein response (UPR). The immune system has evolved to recognize this stress as damage-associated molecular patterns (DAMPs), which activate innate immunity. We are using human cells and tissues to determine how cellular stress, innate immunity, and adaptive immunity cooperate to initiate and perpetuate depigmentation in vitiligo. Developing a humanized mouse model of immune-skin interactions to serve as a pre-clinical bridge to clinical studies: We are developing a humanized mouse model of skin disease that consists of an immunodeficient mouse strain as a host for an autologous human skin graft and immune reconstitution in order to study mechanisms of inflammation in the skin, including allergic contact dermatitis, response to infection, tumor immunotherapy, and autoimmunity, all within a fully human environment. This model system will act as a pre-clinical bridge between mouse models and human clinical trials, providing an opportunity to test new treatments on human cells and tissues prior to initiating trials on patients. Tracking real-time autoreactive T cell migration and interactions within the skin: We are using fluorescently/bioluminescently tagged CD8 T cells to track their movements and interactions within the skin in live mice, using real-time confocal microscopy and bioluminescent imaging. Initial studies will focus on the role of cytokines and chemokines in T cell migration within the skin. Clinical trial to test a novel treatment for vitiligo: We are in the early stages of developing a clinical trial based on insights developed from our animal data to test a novel drug for its ability to treat vitiligo.

Postdoctoral Fellow Applications are being accepted for one position. A position is available to develop Cys2His2 zinc finger proteins (ZFPs) for the treatment of monogenic disorders. This project will focus on the creation of ZFPs with novel DNA-binding specificity to recognize sequence elements within genomic loci of therapeutic interest. In collaboration with other laboratories, we will evaluate the activity of these ZFP-based gene therapy reagents in vitro and in vivo in relevant disease models. Applicants will also have the opportunity to learn to apply Cas9 and Cas12a editing systems in vivo.
Potential Rotation Projects Improving the Precision of CRISPR/Cas9 nucleases for gene therapy applications: We are working to improve the precision of the CRISPR/Cas9 system to generate nucleases that will cleave at only a single site in the genome. These engineering efforts focus on increasing the DNA-editing precision of Cas9 and using protein engineering to introduce new properties into the nuclease. Much of this work is now transitioning to the use of Cas9 (and Cas12a) protein-RNA complexes. These modified nucleases will then be applied to patient derived cell-culture systems for the targeted repair or inactivation of disease-causing alleles. With the eventual goal of creating therapeutics for Sickle Cell Disease, beta-Thalassemia, HIV, Limb Girdle Muscular Dystrophy, Hermansky Pudlak Syndrome and other monogenic disorders. ex vivo genome editing in CD34+ HSPCs: We are developing improved Cas9 proteins for delivery ex vivo into CD34+ HSPCs for therapeutic application to sickle cell disease and beta-thalassemia. The goal is to modify the hematopoietic stem cells of a patient to complement the loss of function of the beta-globin gene and then return these cells to the patient through an autologous transplant. Development of Cys2His2 Zinc fingers proteins (ZFPs) as targeted therapeutics: We are developing artificial ZFPs for the regulation of target genes to change their gene expression profiles for therapeutic applications.

Rotation projects are designed to expose students to the biology of adult stem cells, the mechanisms of tumorigenesis and to provide them with an appreciation for translational cancer research. These projects are focused on the major themes of the lab, which are: 1. Understanding the relative effects of oncogenic mutations on stem cells compared to the non-stem cell population from adult human skin. A key component of this project is to evaluate the Beta-catenin/Lef-1 signaling pathway on cultured epithelial stem cells and non-stem cells. 2. Studying the function of differently expressed genes in mediating stem cell behavior. The goal of this project is to understand the molecular mechanisms which control the critical properties of stem cell self-renewal, proliferation, adhesion and migration. 3. Identifying, isolating and characterizing “cancer stem cells” from human and mouse model tumors. Cancers are thought to possess a sub-population of slowly-cycling cancer stem cells which are responsible for tumor growth, recurrence and metastasis. The goal of this project is to begin to characterize these cells to help better target them therapeutically. The goal for all of these projects is to use the data obtained to help understand human tumorigenesis at the molecular, cellular and tissue levels, and be able to devise better treatments.
