James,Samuel,Regents Professor and Head,"Our laboratory works with the obligate intracellular bacterial pathogen, Coxiella burnetii, the etiologic agent of Q fever and a category B biothreat agent. The long-term goal of this research is to understand the molecular pathogenic mechanisms involved in the host-pathogen interaction. To accomplish this broad goal, project in the lab are designed to test the molecular mechanisms employed by both the host and pathogen. Current pathogen studies include 1) broad survey of proteins secreted via a type 4 secretion system (T4SS) followed by determination of essentiality of each substrate for virulence and detailed analysis of mechanism of host modulation 2) survey of essential virulence loci identified by specific mutant screens, and 3) definition of the relative virulence of phylogenetically distinct isolate groups.",Regents Professor and Head,Microbial Pathogenesis and Immunology,https://scholars.library.tamu.edu/vivo/display/n01c3216f
Zhilong,Yang,Associate Professor,"The overarching research goal of the Yang laboratory is to understand the mechanisms governing viral replication, with the rationale that the discoveries will expand the knowledge of both viruses and their hosts, and facilitate the development of novel strategies to combat viral and non-viral diseases. A parallel goal of Yang lab is to provide a highly supportive environment to train the next generations of scientists. The ongoing research focuses on how viruses interact with two cellular housekeeping processes: protein synthesis and metabolism using vaccinia virus as the research model. Vaccinia virus is the prototype poxvirus. Poxviruses significantly impact public health, with many presently causing morbidity and mortality in humans and many economically important animals, including deadly zoonotic pathogens (e.g., monkeypox virus). In addition, despite the eradication of smallpox, one of the most (if not the most) devastating diseases in human history, smallpox resurgence remains a serious biothreat. Poxviruses are also widely developed as veterinary and human vaccine vectors and as cancer treatment agents. Poxviruses provide numerous precious tools to understand many aspects of cell biology and dissect complex life processes, as their large DNA genomes encode hundreds of genes that engage many key nodes of cellular life. Yang's research integrates biochemical, molecular, and omics approaches. Taking advantage of their in-depth knowledge of the poxvirus replication and virus-host interactions, the Yang lab also develops vaccinia virus-based utilities and anti-virals.",Associate Professor,Veterinary Pathobiology,https://scholars.library.tamu.edu/vivo/display/n02daa01b

Timothy,Devarenne,Associate Professor,"We study the biochemical and molecular mechanisms underlying the control of programmed cell death (PCD) in plants and how PCD is manipulated during plant-pathogen interactions. Specifically we study the interaction between tomato and Pseudomonas syringae pv. tomato (Pst) the causative agent of bacterial spot disease. Resistance to this disease is conferred by the host Pto serine/threonine protein kinase which recognizes Pst strains expressing the type III effector protein AvrPto.
PCD is induced during both resistant and susceptible plant-pathogen interactions. In the case of a resistant interaction, PCD induced by the plant, known as the hypersensitive response (HR), and acts to limit the spread of the pathogen. In susceptible plant-pathogen interactions plant PCD is induced by the pathogen after infection leading to death of the host. Studies have indicated that the genes controlling host PCD during the HR are the same genes that are manipulated by the pathogen during susceptible interactions. The difference lies in the timing of controlling the activity of these genes; HR PCD occurs within 12 hours of pathogen recognition while pathogen-induced PCD occurs several days after infection.
Many of these genes that control plant PCD are serine/threonine (S/T) protein kinase. We are interested in studying a specific class of S/T protein kinases that control PCD in plants called AGC kinases and how they are regulated in both resistant and susceptible plant-pathogen interactions. Additionally, when plants are not attacked by pathogens, PCD is a process that requires constant control so that cell death does not occur. We are looking at the signaling mechanisms and pathways employed to keep PCD under check in non-pathogen challenged plants.",Faculty Affiliate||Associate Professor,Energy Institute||Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/n11411275

Deborah,Bell-Pedersen,Professor,"Research in the Bell-Pedersen lab focuses on determining how the circadian clock functions in organisms to regulate daily rhythms in gene expression, behavior, and physiology. The molecular clock in higher eukaryotes involves a master clock in the brain regulating clocks in peripheral tissues, posing significant obstacles for understanding circadian output mechanisms. Thus, a major strength of our work is using a single-celled model eukaryote, Neurospora crassa, to elucidate the underlying mechanisms of rhythmic gene expression and protein synthesis. Clock dysfunction in humans is associated with a wide range of diseases, including cardiovascular disease, cancer, metabolic disorders, mental illness, sleep disorders, and aging. In addition, daily changes in metabolism and cell division rates influence the efficacy and toxicity of many pharmaceuticals, including cancer drugs. Therefore, knowing how clocks work to control rhythmic gene expression, and what they regulate, is critical for the development of therapeutics. Research to understand clock-controlled rhythmic gene expression has focused primarily on transcriptional mechanisms, and little was known about posttranscriptional control. We discovered that the clock regulates highly conserved translation initiation and elongation factors, tRNA synthetase levels, and ribosome heterogeneity. This regulation determines what mRNAs are rhythmically translated and the accuracy of the translation process (translation fidelity). We are capitalizing on these exciting discoveries to determine how the clock regulates translation fidelity. These studies will provide the foundation for understanding the impact of daily rhythms in translation fidelity on protein diversity beyond what is encoded for in the genome.",Professor and Associate Department Head,Biology,https://scholars.library.tamu.edu/vivo/display/n2a2bfb97

C. difficile is a Gram-positive, spore forming, anaerobe that causes infections in people who have undergone antibiotic regimens. Previously, we had shown that certain bile acids promote C. difficile spore germination while others inhibit germination. Bile acids are small molecules made by the liver that help the absorption of fat and cholesterol in the GI tract while also serving as a protective barrier against invading pathogens. Because C. difficile spores use the ratios of bile acids as cues for germination, the actively growing bacteria must have adapted means to avoid their toxic properties. We are currently focused on identifying these factors and the mechanisms by which C. difficile spores germinate.",Professor,Biology,https://scholars.library.tamu.edu/vivo/display/n2b4d6c14

Pingwei,Li,Professor,"The research in my lab focuses on elucidating the structural basis of innate immune responses towards microbial nucleic acids. The cGAS/STING pathway plays a central role in innate immunity toward bacterial and viral DNA. cGAS is activated by dsDNA and catalyzes the synthesis of a cyclic dinucleotide cGAMP, which binds to the adaptor STING that mediates the recruitment and activation of protein kinase TBK1 and transcription factor IRF-3. Activated IRF-3 translocates to the nucleus and induces the expression of type I interferons (IFN), an important family of antiviral cytokine. To elucidate the mechanism of cGAS activation, we determined the structures of cGAS in isolation and in complex with DNA. The cGAS/DNA complex structure reveals that cGAS interacts with DNA through two binding sites. Enzyme assays and IFN-? reporter assays of cGAS mutants demonstrate that interactions at both DNA binding sites are essential for cGAS activation. To investigate how cGAMP activates STING, we determined the structures of STING in isolation and in complex with cGAMP. These structures reveal that STING forms a V-shaped dimer and binds cGAMP at the dimer interface. We have also determined the structures of TBK1 in complex with two inhibitors, which show that TBK1 exhibits an I?B kinase fold with distinct domain arrangement. To elucidate the mechanism of IRF-3 recruitment by STING, we determined the structure of a phosphorylated STING peptide bound to IRF-3. To understand how phosphorylation activates IRF-3, we solved the structure of an IRF-3 phosphomimetic mutant bound to CBP, which reveals how phosphorylation induces the dimerization and activation of IRF-3.",Professor,Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/n31ebad17

Beiyan,Nan,Assistant Professor,"I am interested in understanding the mechanisms of fundamental biological processes in bacteria. My lab uses soil bacterium Myxococcus xanthus as the model organism. Several aspects of M. xanthus make it an ideal model for understanding bacterial physiology. First, M. xanthus cells utilize sophisticated systems to move on solid surfaces, which involve cytoplasmic and periplasmic proteins, filamentous cytoskeletons, membrane channels, cell wall, and cell surface components. Second, cells constantly communicate with each other and with their environment. Cells usually move in coordinated groups but also as isolated ""adventurous"" individuals, which allows this bacterium to feed on soil detritus and prey on other microorganisms. Third, when the availability of nutrients or prey decrease in the environment, most cells exhibit behaviors that include aggregation into fruiting bodies and conversion of individual cells into spores.
I have been using the super resolution photo-activated localization microscopy (PALM) to track single molecule dynamics of proteins in live bacterial cells. With this technique, I have achieved 10 millisecond time resolution (100 frames per second) and 80 nm spatial resolution. These studies were initiated because the most widely used fluorescence microscopy techniques (including confocal, deconvolution, etc.) can only provide resolution to about 200 nm due to the diffraction of light, which is often insufficient for many studies because of the small size of bacterial cells (usually a few hundred nanometers in diameter).

Thomas,Meek,Professor,"Marketed drugs have been developed for representatives of all six classes of enzymes, and comprise essential therapies for the treatment of cancers, HIV/AIDS, hypercholesterolemia, and bacterial infections. The availability of known point mutations that are causative of human cancers , as well as the full genomic descriptions of many pathogens, such as parasitic protozoa and infectious bacteria, provides an emerging means to identify new or known enzymes that would constitute potential drug targets. Likewise, the availability of crystal structures of many of these enzymes or their analogues, provides a means to rationally design new inhibitors of enzyme drug targets via the use of molecular modelling and a full understanding of the chemical mechanism of the target enzymes, as an important adjuvant to inhibitor discovery via high-throughput screening.
Our laboratory will initially focus on the detailed study of the mechanisms of cysteine proteases such as cathepsin C, the isocitrate lyase of Mycobacterium tuberculosis, and human ATP-citrate lyase, by the use of pre-steady-state and steady-state kinetics, as well as by use of existing crystal structures of these enzymes, to inform the design of both covalent and other mechanism-based modes for the inactivation of these enzymes.

Thomas,Mcknight,Professor and Head,"My lab is currently investigating mechanisms that regulate telomerase activity in plants. We previously showed that the pattern of telomerase expression in plants is remarkably similar to the pattern seen in humans, despite fundamental differences in development between plants and animals. Telomerase is abundantly expressed in reproductive organs but is undetectable in most vegetative organs (Fitzgerald et al., 1996). Additionally, telomerase can be induced in leaves and other vegetative organs by exposure to exogenous auxin.
To isolate genes that regulate telomerase, we screened a large population of activation tagged lines of Arabidopsis thaliana, and found that several lines that ectopically express telomerase in leaves. The first line we characterized over-expressed a gene encoding a small zinc finger transcription factor we designated TELOMERASE ACTIVATOR 1 (Ren et al., 2004). This factor does not bind to the promoter for TERT, which encodes the catalytically active subunit of telomerase. Instead, it binds to and activates transcription of BT2, a gene encoding a component of a ubiquitin ligase (Ren et al., 2007). Our working model is that the BT2 ubiquitin ligase marks a telomerase repressor for destruction, thereby allowing expression of telomerase. Efforts in the lab are currently focused on identifying the presumed telomerase repressor protein and other proteins that interact with BT2.",Professor and Head,Biology,https://scholars.library.tamu.edu/vivo/display/n5c3b294a

Daniel,Ebbole,Professor,"Development and pathogenesis share the common features of responding to environmental conditions to execute a program of gene expression resulting in new cell types.
An important question in plant pathogenesis is to understanding the functions of pathogen effectors and their host target(s). Fungal effectors play roles in suppressing host defense mechanisms, however, other biotrophic functions, such as manipulating host physiology to promote nutrient acquisition and cell-to-cell movement are possible. Therefore, identification of the full set of fungal proteins secreted during host invasion is a major effort in plant pathology research. Candidate effectors are generally identified by virtue of i) their expression in planta ii) assessing their activity on the host using purified proteins or by manipulating expression iii) detecting the rapid evolution of effector genes due to selective pressure from the host. My lab is using a combination of these approaches to identify and characterize a gene family of putative effectors from Magnaporthe oryzae, the rice blast fungus and define interactions with monocot hosts.",Professor,Plant Pathology and Microbiology,https://scholars.library.tamu.edu/vivo/display/n86da3f1b

Paul,Lindahl,Professor,"One of our two current research areas involves iron metabolism in mitochondria. The iron imported into these organelles is assembled into iron-sulfur clusters and heme prosthetic groups. Some of these centers are exported into the cytosol, while others are installed into mitochondrial apo-proteins. All of these processes are regulated in healthy cells, but various genetic mutations giving rise to diseases can cause iron to accumulate (e.g. Friedreich's ataxia) or become depleted (e.g. Sideroblastic anemia). We have developed a biophysical approach involving Mossbauer, electron paramagnetic resonance, and electronic absorption spectroscopy, to study the entire iron content of intact mitochondria in healthy and genetically altered cells. This Systems Biology approach allows us to characterize the ""iron-ome"" of mitochondria at an unprecedented level of detail. We are also using analytical tools (e.g. liquid chromatography) to identify complexes that are involved in ""trafficking"" iron into and out of the organelle.
Our other research area involves mathematical modeling of cellular self-replication on the mechanistic biochemical level. We collaborate on this multidisciplinary NSF-sponsored project with a mathematician at the University of Houston (Professor Jeffrey Morgan). We have developed a modeling framework that facilitates such modeling efforts, and have designed a number of very simple and symbolic in silico cells that exhibit self-replicative behavior. Our minimal in silico cell model includes just 5 components and 5 reactions. A second generation model includes a more realistic mechanism of mitotic regulation. One novel aspect of our approach is that cellular concentration dynamics impact (and are impacted by) cellular geometry. By minimizing membrane bending energies, we are now calculating cell geometry during growth and division. Our results suggest that the ""pinching"" observed in real cells is enforced by cytoskeletal structures.",Professor,Chemistry,https://scholars.library.tamu.edu/vivo/display/nc9ce621b

Their most conspicuous behavior is chemotaxis - the pursuit of molecules that are favorable to acquire and the avoidance of chemicals that are best to avoid. The simplicity of bacterial motility and chemotaxis and the amenability of the model species Escherichia coli to genetic, biochemical and physiological manipulation have facilitated rapid advances in understanding the molecular mechanisms of biological energy conversion and signal transduction.
Our laboratory studies the inputs and outputs of chemotaxis. Ligands interact with the periplasmic receptor domain of a chemotactic signal transducer that spans the cell membrane. This interaction is converted into an intracellular signal that is communicated to the flagella. Molecules can be sensed either by binding directly to a receptor or by first interacting with a periplasmic binding protein, which then interacts with a receptor.",Professor||Professor,Biology||Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/ne190242a
Deborah,Siegele,Associate Professor,"Phenotypes are observable characteristics of an organism that result from the expression of a particular genotype in a particular environment. Examples of phenotypic traits in microbes are motility, sporulation, ability to perform anaerobic respiration, and resistance/sensitivity to an antibiotic.
Until recently, phenotypic information has been captured as free text descriptions in research papers. Ambiguities in natural language confound attempts to retrieve information across sources. For example, ""serotype"" and ""serovar"" both refer to the same phenotype, but a simple text-based query with either word alone would miss the other. Or a single term, such as ""sporulation"" is used to refer to multiple, distinct processes in different organisms. Issues such as these hamper the ability to integrate different phenotypic data sets for the same organism or to use phenotypic information in one organism to predict possible phenotypes in another organism. Ideally, phenotype information should be stored in a consistent, computable format for ease of data integration and mining.
Controlled vocabularies are used to provide both consistent terminology and a structured data format for the capture of biological information. Ontologies are controlled vocabularies of defined terms with unique identifiers and precise relationships to each other. There are phenotype ontologies available for many eukaryotic organisms, including fungi. However, when the OMP project was initiated, none of the existing ontologies was appropriate to comprehensively capture phenotypes for Bacteria or Archaea or to enable comparisons across microbial taxa.
The Siegele lab and our collaborators at TAMU and the Univ. of Maryland (IGS) are developing a formal Ontology of Microbial Phenotypes (OMP). Our lab is focused on term development and annotating microbial phenotypes. OMP can be accessed at microbialphenotypes.org.

Ryland,Young,Professor,"Most bacterial viruses (phages) cause lysis of their host cell to release the progeny virions. Large phages elaborate an enzyme (""endolysin"") to degrade the cell wall and also a small membrane protein (""holin""). The holin accumulates in the membrane and then, at a precisely scheduled time, suddenly forms a hole to allow release of endolysin through the cytoplasmic membrane to gain access to the wall. We use molecular genetics and biochemistry to study how this small protein is able to act as a molecular ""clock"" and punch holes in membranes. Small phages make single proteins which cause host lysis in a different way. This strategy is to target the host cell wall synthesis machinery; that is, the virus makes a ""protein antibiotic"" that causes lysis in the same way as antibiotics like penicillin by inhibiting an enzyme in the multi-step pathway of murein biosynthesis. Thus, when the infected cell tries to divide, it blows up, or lyses, because it can't make the new cell wall between the daughter cells. Remarkably, each of three different, small phages blocks a different step in the pathway. These small lysis proteins are models for a completely new class of antibacterial antibiotics. Also, the E. coli SlyD protein is required for this mode of lysis in one case. SlyD is a member of an ubiquitous family of proteins related to human ""immunophilins,"" the targets of immune-suppression drugs. We study SlyD to learn about the role of this class of proteins in biology.",Professor,Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/nea775348

Richard,Gomer,Distinguished Professor,"Our laboratory is working on three areas of biomedicine, trying to move observations from basic research into the clinic. First, we are studying how the sizes of tissues and tumors are regulated, and how this can be manipulated for therapeutic purposes. As a model system, we are using the simple eukaryote Dictyostelium discoideum, which allows us to combine techniques such as biochemistry, genetics, computer modeling, and cell biology to study tissue size regulation. We have found that a secreted protein as well as the unusual molecule polyphosphate are signals in negative feedback loops that inhibit Dictyostelium cell proliferation, and we are studying the signal transduction pathway to understand similar mechanisms in humans.
Second, we are studying how some secreted proteins can make cells move away from the source of the signal. We found such a signal (called a chemorepellent) in Dictyostelium, and then found a similar signal in humans. We are working to understand the signal transduction pathway for both. The human signal repels neutrophils, and we found that this can be used therapeutically in mouse models of neutrophil-driven diseases such as rheumatoid arthritis and acute respiratory distress syndrome.
Third, we have found that a human blood protein called Serum Amyloid P (SAP) regulates a key step in the formation of scar tissue as well as the formation of the scar-like lesions in fibrosing diseases such as congestive heart failure and pulmonary fibrosis. We are studying this mechanism, and a biotech company (Promedior, now sold to Roche) we co-founded is testing SAP as a therapy for fibrosis in patients in a Phase 3 trials.",Distinguished Professor,Biology,https://scholars.library.tamu.edu/vivo/display/nf41f3898

Matthew,Sachs,Professor,"Understanding the mechanisms by which upstream open reading frames (uORFs) in mRNA transcripts control gene expression is currently the major focus of my laboratory. A substantial component of this work is focused on the uORF-encoded fungal arginine attenuator peptide (AAP). The major goal of this work is to understand the mechanism by which a nascent peptide encoded by this uORF controls the movement of ribosomes on mRNA and regulates gene expression. Control mechanisms mediated by uORFs and nascent peptides exist in mammals, fungi, plants, viruses, and bacteria, but relatively little is known of the molecular details of such control. The AAP is encoded by a uORF in the 5?-leader regions of mRNAs specifying the first enzyme in fungal arginine (Arg) biosynthesis. Synthesis of the AAP rapidly reduces gene expression in response to Arg. AAP-mediated regulation is observed in vivo in both Neurospora crassa and Saccharomyces cerevisiae and in vitro, using fungal, plant and animal extracts. The nascent AAP causes the ribosome to stall when the concentration of Arg is high.",Professor,Biology,https://scholars.library.tamu.edu/vivo/display/nfe74574c

I am interested in how vector-borne pathogens influence host and vector cellular responses, such as immune responses, cellular trafficking, and vesicle secretion.
We are also interested in how tick-borne pathogens sense environmental changes when moving between the vector and the mammalian host. Members of the Anaplasmataceae change their protein profile during their development within the mammalian host when compared to the vector. We want to use these bacteria as a model to understand what clues intracellular bacteria use to detect changes in environment.
