Rotation projects are available to study chromatin structure and function. Project 1. Measure histone dynamics in yeast. Histone dynamics play major roles in chromatin metabolism and in the inheritance of chromatin states. To measure histone replacement rates in yeast, we have created yeast strains carrying inducible epitope-tagged histones H3 and H2A. Using microarrays, we will measure histone replacement rates in a variety of mutant yeast to ascertain the role of various chromatin remodeling factors in histone exchange reactions. Project 2. Characterize mechanisms for epigenetic inheritance in yeast. We have identified a variety of genes whose expression state in yeast is epigenetically heritable. We will screen the yeast genome for genes that affect the inheritance of these expression patterns. Project 3. Measure histone dynamics in embryonic stem cells. Embryonic stem cells are pluripotent cells that can give rise to every type of cell in the adult animal. The role of chromatin structure in maintaining this pluripotent state is poorly understood, but it appears that stem cell chromatin is exceptionally labile relative to that in differentiated cells. We will create stem cell lines with inducible tagged histones to measure histone replacement rates across the mouse genome.
Rotation Projects Rotation projects are available to address the following questions: How does the lack of structure in the C-terminal zinc finger of TTP affect the activity of the protein in the cell? In humans, there are three members in the TTP protein family: TTP, TIS11b and TIS11d. Structural studies performed by us and others have shown that while the TZF domain of TTP is partially unstructured in the free state and folds upon binding RNA, those of TIS11d and TIS11b are always folded. We have shown that the degree of structure of the TZF domain affects the activity of the protein in cells and indicates that the protein can modulate its activity through its dynamics. We want to determine whether structural disorder is directly linked to cellular stability or protein localization How do mutations in the RNA-binding domain of TIS11d cause cancer? Several point mutation in TTP and TIS11d have been linked to cancer. In particular, point mutations in the RNA-binding domain of TIS11d are found in leukemia patients. We are currently working on the characterization of the structure, dynamics and biological activity of these mutant proteins to understand their role in the pathogenesis of cancer. How does HuR regulate the stability of its target mRNA? HuR is another protein that, like TTP, binds to AU-rich elements (ARE) in mRNAs and regulate their stability. The detailed mechanisms that determine how HuR regulates transcripts stability are poorly understood. We are investigating how binding or HuR to the 3’UTR of an mRNA leads to its stabilization.

Rotation Projects Our rotation projects are in the area of diabetes and obesity, and we are interested in basic mechanisms of cell proliferation, differentiation and communication. Diabetes is highly correlated with obesity, but why obesity causes disease in some humans and not others is not understood. Amazingly, we still don’t understand how adipose tissue grows in human adults. A better understanding of this fascinating process can give us insight into basic mechanisms of cell growth, differentiation and communication, as well as mechanisms of disease, not only diabetes but also cancer and developmental defects. During your rotation, you will work on an important piece of a larger project, that has a well-defined outcome. Thus, your successful completion of the rotation project will allow you to be included at the time of publication of the work. Project 1: Adipose tissue is not only formed by adipocytes, but by other cells such as endothelial, mural and immune cells. Also, there are multiple kinds of adipocytes with different functions. We have recently developed conditions to develop adipose tissue from humans in-vitro (adipose tissue “organoids”). From this tissue we have been able to separated single cells, and find that they grow into different kinds of clones. We are now conducting RNAseq on >300 of those clones, to determine how many cell types exist in human adipose tissue, and what their roles are. In this rotation, you will be able to analyze RNAseq data to define what genes characterize these cells, and you will use virus transduction to create immortalized cells for further study. Project 2: Adipose tissue has many functions besides storing and releasing lipids. It also has to coordinate metabolism in the whole body. We have found that human “beige” adipose tissue, which is found in people who are metabolically healthy, expresses genes for secreted factors that communicate with the immune system and the brain. These include IL-33 and enkephalins. In this project you will knockout these genes, and investigate whether this changes the function of adipose tissue when we implant it into immune compromised mice.

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.
Determine links between SREBPs, SAMe levels and epigenetic regulation Methylation of histones or DNA affects gene expression at local as well as global levels. The major cellular methyl donor, s-adenosylmethionine (SAMe) is produced by the folate or 1-carbon (1C) cycle. 1CC function may be affected by dietary levels of folate, methionine, choline or betaine, genetic polymorphisms, or alcohol intake, linking potential for epigenetic modification in cancer progression to food intake and metabolism. Physiological limitation of 1CC function has multiple deleterious physiological effects from birth defects to the development of hepatosteatosis and has also been linked to hepatic and colon cancer. While many studies have shown that the availability of methyl donors may dramatically affect human disease, the mechanisms governing SAMe production and epigenetic modification are much less clear. We hypothesize that modulation of SBP-1 function affecting sams-1 expression will also alter methyl group levels and subsequently, histone modification, leading to changes in gene expression relevant to overall nutritional homeostasis. We will determine if modulation of SAMe levels through SBP-1 effects histone methylation at nutritionally important promoters and examine how diet quality and dietary supplementation affect SBP-1 activity by evaluating histone methylation, in addition to employing biological assays for epigenetic changes in gene expression. We will also use unbiased assays such as ChIP-Seq to identify genes whose expression levels are linked to epigenetic changes after sbp-1 RNAi, selecting those with roles in metabolism for further study. These studies will provide a basis for understanding how lipid homeostasis and other dietary influences affect SAMe production and how those are linked to increased lipid accumulation in C. elegans. Future studies will extend these models to mammalian systems to investigate how these changes predispose hepatosteatosis, a component of metabolic syndrome in humans.
Determine mechanisms for differential regulation of SREBP-1 and SREBP-2 by PC-based feedback In recent studies, we have found that inactive precursors for SREBP-1 are cleaved, accumulate in the nucleus and activate lipogenic transcription programs when membrane changes linked to low PC levels alter localization of SREBP-activating proteases (see Research Interests). We also found that SREBP-2 was resistant to this regulation (Figure 1), and note that while mouse models of PC depletion are associated with hepatic steatosis, cholesterol levels are not necessarily affected (Jacobs, et al. 2008, JBC). We will determine the mechanisms of this differential regulation which will be important for understanding how lipid or cholesterol synthesis may be inappropriately stimulated in metabolic disease. Figure 1: Depletion of PC biosynthesis enzymes in HepG2 human hepatoma cells causes nuclear localization of SREBP-1, but not SREBP-2. Yellow line shows cell boundary
Identify cellular responses to decreased SAMe production Our studies in C. elegans showed that SREBP transcriptional activators could control expression 1CC genes. These studies are important because they demonstrate that levels of these critical enzymes mRNAa are not controlled as a “housekeeping function” but are instead are coordinated with other cellular processes. We have developed two models for 1CC dysfunction in C. elegans, a genetic model based on loss of function (lof) of sams-1, a SBP-1/SREBP responsive gene encoding the enzyme for producing the methyl donor SAMe and a dietary model in which C. elegans are fed bacteria unable to synthesize folate. In both of these models, transcription of lipogenic genes are highly increased and sams-1(lof) worms accumulate large lipid droplets, mimicking aspects of fatty liver disease in mammals. These models will allow use genetic screens as a tool for identifying 1) other regulatory pathways affecting SAMe production or utilization and 2) cellular responses that limit lipogenesis when methyl donor levels are low.

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.

Rotation Projects 1) Molecular and neuronal characterization of C. elegans escape behavior Defining sensorimotor circuits requires detailed knowledge of the neural connectivity of the nervous system, and the ability to manipulate the functions of the component neurons and to define and quantify the behavioral outputs. The simplicity and completely defined synaptic connectivity of C. elegans nervous system provides unique opportunity to dissect how neural networks control behavior. 2) Identify genes involved in the processing, expression and subunit composition of voltage-gated calcium channels The release of neurotransmitter from synaptic vesicles is critical for the propagation of signals that generate behavioral outputs. Voltage-gated calcium channels provide the calcium influx essential for synaptic vesicle exocytosis. We are characterizing mutants to identify new genes involved in the proper assembly, expression and trafficking of functional calcium channels. 3) Investigate the evolutionary origins of escape behavior Nematophagous fungi employ a variety of strategies to capture worms. In predator-prey experiments, we have been able to show that the suppression of head movements allows the animal to escape from constricting traps. Further investigation of the neurobiology behind the escape from predation may provide insight into how this behavior evolves.
