Our research is focused on two general areas:  1. Autism and 2. Pain.  Our autism research is focused on topoisomerases and other transcriptional regulators that were recently linked to autism.  We use genome-wide approaches to better understand how these transcriptional regulators affect gene expression in developing and adult neurons (such as RNA-seq, ChIP-seq, Crispr/Cas9 for knocking out genes).  We also assess how synaptic function is affected, using calcium imaging and electrophysiology.   In addition, we are performing a large RNA-seq screen to identify chemicals and drugs that increase risk for autism.   /  / Our pain research is focused on lipid kinases that regulate pain signaling and sensitization.  This includes work with cultured dorsal root ganglia (DRG) neurons, molecular biology and behavioral models of chronic pain.  We also are working on drug discovery projects, with an eye towards developing new therapeutics for chronic pain.

The Hathaway lab is focused on understanding the biological events responsible for dynamically regulating the selective expression of the mammalian genome. In multicellular organisms, genes must be regulated with high precision during stem cell differentiation to achieve normal development. Pathologically, the loss of proper gene regulation caused by defects in chromatin regulatory enzymes has been found to be a driving force in cancer initiation and progression. My lab uses a combination of chemical biology and cell biology approaches to unravel the molecular mechanisms that govern gene expression. We utilize new tools wielding an unprecedented level of temporal control to visualize changes in chromatin structure and function in mammalian cells and animal models. In addition, we seek to identify small molecule inhibitors that are selective for chromatin regulatory enzymes with the potential for future human therapeutics.

My research aims to uncover the molecular aspects of protein aggregation diseases (also called PAD) which include neurodegenerative diseases (such as Alzheimer’s disease and Amyotrophic Lateral Sclerosis), myofibrillar myopathies (such as muscular dystrophies), as well as the formation of age-related cataracts.  Although very distinct, these disorders share a common underlying pathogenic mechanism.  Using a combination of biochemistry and in vitro approaches, cell biology, and primary cells / transgenic mouse models, we will investigate the post-translational modifications (PTMs) that drive these disease processes. Ultimately, this research will provide a platform for future drug discovery efforts against these devastating diseases.

Our lab is trying to understand the mechanisms by which long noncoding RNAs orchestrate the epigenetic control of gene expression. Relevant examples of this type of gene regulation occur in the case of X-chromosome inactivation and autosomal imprinting. We specialize in genomics, but rely a combination of techniques —  including genetics, proteomics, and molecular, cell and computational biology — to study these processes in both mouse and human stem and somatic cell systems.

My research philosophy is summed up by a quote from Nobelist Albert Szent-Gyorgyi: “Discovery is to see what everybody has seen and to think what nobody has thought.” My lab studies the molecular and physical mechanisms of cell shape change during cytokinesis and tissue biogenesis during development. Specifically, we are defining how cells ensure proper alignment and sliding of cytoskeletal filaments, and determining the shape of the cell throughout division. To do so, we combine developmental biology, cell biology, biochemistry, and quantitative image analysis.

The overall focus of research in my laboratory is to improve the diagnosis and treatment of airway diseases, especially those that result from impaired mucociliary clearance. In particular, our efforts focus on the diseases cystic fibrosis and primary ciliary dyskinesia, two diseases caused by genetic mutations that impair mucociliary clearance and lead to recurrent lung infections. The work in our laboratory ranges from basic studies of ciliated cells and the proteins that make up the complex structure of the motile cilia, to translational studies of new drugs and gene therapy vectors. We use a number of model systems, including traditional and inducible animal models, in vitro culture of differentiated mouse and human airway epithelial cells, and direct studies of human tissues. We also use a wide range of experimental techniques, from studies of RNA expression and proteomics to measuring ciliary activity in cultured cells and whole animals.

The Loeser lab uses a combination of in vitro studies in articular chondrocytes and in vivo studies in mice to examine molecular mechanisms of joint tissue destruction in aging and osteoarthritis. A major focus of this work is examining how reactive oxygen species regulate cell signaling through oxidation of Cys residues in specific kinases and phosphatases. Pathways of interest include integrin mediated signaling that stimulates matrix metalloproteinase (MMP) expression and IGF-I signaling that stimulates matrix production. Oxidative stress disrupts the balance in the activity of these pathways to favor matrix destruction over repair contributing to the development of osteoarthritis.

My research program is centered on understanding fundamental aspects of cell division. During cell division, complex DNA-protein interactions transform diffuse interphase chromatin into discrete mitotic chromosomes, condensing them several thousand fold to facilitate spatial segregation of sister chromatids. Concomitantly, kinetochores form specifically at centromere regions of chromosomes and regulate force-producing interactions with microtubules. While these processes are absolutely required for genomic stability, the in vivo mechanisms of chromosome and kinetochore assembly remain unsolved problems in biology. I investigate 1) the spatiotemporal regulation of mitotic chromosome assembly, and 2) the molecular basis of centromere specification. To do so, I will combine biochemical approaches with high-resolution light microscopy of live cells, whole organisms, and in vitro systems.

Research in the Darville lab is focused on increasing our understanding of immune signaling pathways active in development of genital tract disease due to Chlamydia trachomatis and determination of chlamydial antigen-specific T cell responses that lead to protection from infection and disease. In vitro, murine model, and human studies are being performed with the ultimate goal to develop a vaccine against this prevalent sexually transmitted bacterial pathogen. Genetic and transcriptional microarray studies are being performed to explore pathogenic mechanisms and determine biomarkers of pelvic inflammatory disease due to Chlamydia as well as other sexually transmitted pathogens.

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.
