We study the behavior of individual cells with a specific focus on “irreversible” cell fate decisions such as apoptosis, senescence, and differentiation. Why do genetically identical cells choose different fates? How much are these decisions controlled by the cell itself and how much is influenced by its environment? We address these questions using a variety of experimental and computational approaches including time-lapse microscopy, single-molecule imaging, computational modeling, and machine learning. Our ultimate goal is to not only understand how cells make decisions under physiological conditions—but to discover how to manipulate these decisions to treat disease.

My laboratory is interested in the role of folate and related metabolic pathways in methyl group metabolism, and their involvement in pathogenesis and etiology of diseases. We have recently discovered a novel function of a folate-binding methyltransferase GNMT in the regulation of cellular proliferation, and now study the genetic variations in GNMT and their effects on new function. Our lab is also interested in the cross talk between folate metabolism and sphingolipid pathways as a mediator of folate stress with the goal of exploiting this connection to improve human health.

Dr. Hursting’s lab focuses on the molecular and metabolic mechanisms underlying nutrition and  cancer associations, particularly the impact of obesity and energy balance modulation (eg, calorie restriction, exercise) on cancer development or responses to chemotherapy. Primarily using genetically engineered mouse models of pancreatic, colon and breast cancer, Dr. Hursting has identified the IGF-1/Akt/mTOR and NF-kB signaling pathways as key targets for breaking the obesity- cancer link.  He has also established in several preclinical models of pancreatic and breast cancer that obesity impacts the response to various forms of chemotherapy.  In addition, the Hursting lab is involved in several translational research collaborations linking mouse model studies with clinical trials, and his group has expertise in measuring metabolic hormones, growth factors, inflammatory cytokines and chemokines in serum and tissue from rodents and humans.

Dr. Krupenko’s research is focused on the role of folate metabolism in cellular homeostasis and cancer disease. He is especially interested in the function of a major folate enzyme and a putative tumor suppressor ALDH1L1 as metabolic regulator and a guardian of non-malignant phenotype. At present he studies function of this enzyme and related proteins using mouse knockout models. Recently his research team has also demonstrated that dietary folate regulates cancer metastasis. He now pursues studies of specific signaling pathways involved in metastatic response to dietary folate status.

Research in the lab focuses on how a single genome gives rise to a variety of cell types and body parts during development. We use Drosophila as an experimental system to investigate (1) how transcription factors access DNA to regulate complex patterns of gene expression, and (2) how post-translational modification of histones contributes to maintenance of gene expression programs over time. We combine genomic approaches (e.g. CUT&RUN/ChIP, FAIRE/ATAC followed by high-throughput sequencing) with Drosophila genetics and transgenesis to address both of these questions.

The goal of my research is to define molecular mechanisms of immune cell co-option by cancer cells, with the hope of identifying novel targets for immune cell reprogramming. Central to our approach is analysis immune cell subtypes in KRas-driven models of pancreatic cancer. We use cell and animals models to study signals important for pro-tumorigenic activity of immune cells, as well as define role of physiologically relevant oncogenic mutations in driving these signals and enabling immune escape.

My lab studies how genes function within the three-dimensional context of the nucleus to control development and prevent disease. We combine genomic approaches (ChIP-Seq, ChIA-PET) and genome editing tools (CRISPR) to study the epigenetic mechanisms by which transcriptional regulatory elements control gene expression in embryonic stem cells.  Our current research efforts are divided into 3 areas: 1) Mapping the folding pattern of the genome 2) Dynamics of three-dimensional genome organization as cells differentiate and 3) Functional analysis of altered chromosome structure in cancer and other diseases.

The Arthur lab is interested in mechanisms by which inflammation alters the functional capabilities of the microbiota, with the long-term goal of targeting resident microbes as a preventative and therapeutic strategy to lessen inflammation and reduce the risk of colorectal cancer. We utilize a unique and powerful in vivo system – germ-free and gnotobiotic mice – to causally link specific microbes, microbial genes, and microbial metabolites with health and disease in the gut.  We also employ basic immunology and molecular microbiology techniques as well as next generation sequencing and bioinformatics to evaluate these essential host-microbe interactions.

Our laboratory studies an amazing regulatory factor known as NF-kappaB. This transcription factor controls key developmental and immunological functions and its dysregulation lies at the heart of virtually all major human diseases.

Our research group utilizes the nematode C. elegans to investigate germ cell immortality: mechanisms that allow germ cells remain eternally youthful as they are transmitted from one generation to the next. We also study how telomerase functions at chromosome termini, as well as the consequences of telomere dysfunction.
