Study of evolution of gene families and genomic variation underlying disease resistance. Investigation of genetic mechanisms in innate immunity with focus on livestock, select agents, and agricultural biosecurity.",Distinguished Professor,Veterinary Pathobiology,https://scholars.library.tamu.edu/vivo/display/n0e1a49e2
Tadhg,Begley,Distinguished Professor,"The Begley Group is interested in the mechanistic chemistry and enzymology of complex organic transformations, particularly those found on the vitamin biosynthetic pathways. We are currently working on the biosynthesis of thiamin, molybdopterin, pyridoxal phosphate and menaquinone. Our research involves a combination of molecular biology, protein biochemistry, organic synthesis and structural studies and provides a strong training for students interested in understanding the organic chemistry of living systems and in pursuing careers in biotechnology, drug design or academia.
Thiamin pyrophosphate plays a key role in the stabilization of the acyl carbanion synthon in carbohydrate and amino acid metabolism. The biosyntheses of the thiamin pyrimidine and thiazole are complex and are different from any of the characterized chemical or biochemical routes to these heterocycles. We are particularly interested in cellular physiology and the mechanistic enzymology of thiamin biosynthesis. As an example of one of the complex transformations on this pathway, the figure below shows the structure of the pyrimidine synthase catalyzing the complex rearrangement of aminoimidazole ribotide (left) to the thiamin pyrimidine (right).",Distinguished Professor,Chemistry,https://scholars.library.tamu.edu/vivo/display/n498aa35b
Roderick,Dashwood,University Distinguished Professor,"Research integrates multiomic, genetic, epigenetic and immune approaches for precision oncology. Epigenetic readers, writers and erasers that reversibly regulate immune players in the antigen presentation pathway are of current mechanistic interest. Molecular and cell-based assays are combined with preclinical models coupled to polypectomy. Clinical specimens and organoids from patients undergoing colectomy provide for human translation. Supported by the NCI, NINDS/NIA, and the John S. Dunn Foundation.",John S.

Fuller,Bazer,Distinguished Professor,"Dr. Bazer's research in reproductive biology focuses on uterine biology and pregnancy, particularly pregnancy recognition signaling from the conceptus to the maternal uterus by interferon tau and estrogen from ruminant and pig conceptuses, respectively. The roles of uterine secretions as transport proteins, regulatory molecules, growth factors and enzymes and endocrine regulation of their secretion is another major research interest. The endocrinology of pregnancy, especially the roles of lactogenic and growth hormones in fetal-placental development and uterine functions are being studied. The mechanism(s) of action and potential therapeutic value of conceptus interferons and uterine-derived hematopoietic growth factors are areas of research with both pigs and sheep as models for human disease.",Distinguished Professor,Animal Science,https://scholars.library.tamu.edu/vivo/display/n7ad91d50
Frank,Raushel,Distinguished Professor,"Enzymes catalyze a remarkable variety of chemical reactions with extremely high rate enhancements and very selective substrate specificity. The research efforts in our laboratory are directed towards a more complete understanding of the fundamental principles involved in enzyme-catalyzed chemistry and the dependence on protein structure. The pursuit of this information will provide the framework for the rational and combinatorial redesign of these complex molecules in an effort to exploit and develop the properties of enzyme active sites for a variety of chemical, biological, and medicinal uses. The techniques that we are using to solve these problems include steady-state and stopped-flow kinetics, NMR and EPR spectroscopy, X-ray crystallography, and the synthesis of inhibitors and suicide substrates. We are also using recombinant DNA methods to construct new proteins with novel catalytic properties. These efforts are currently being directed to the reactions catalyzed by phosphotriesterase and enzymes involves in the degradation of lignin and the metabolism of novel carbohydrates from the human gut microbiome.
The phosphotriesterase enzyme catalyzes the hydrolysis of organophosphate insecticides and other toxic organophosphate nerve agents. We have discovered that the active site of this protein consists of a unique binuclear metal center for the activation of water. We are now investigating the structure and properties of this metal center as a model system for the evolution of enzyme structure and function. Toward this end we have mutated the active site of this enzyme in a research project to create novel enzymes with the ability to detect, destroy, and detoxify various chemical warfare agents such as sarin, soman, and VX. The Raushel laboratory is also engaged in a large scale research project that is focused on the development of novel strategies for the discovery of new enzymes.",Distinguished Professor,Chemistry,https://scholars.library.tamu.edu/vivo/display/na84f2fec
Stephen,Safe,Distinguished Professor,The aryl hydrocarbon receptor (AhR) is a nuclear helix-loop-helix transcription factor which forms a ligand-induced nuclear heterodimer with the AhR nuclear translocator (Arnt) protein. Research in this laboratory is focused on the molecular mechanism of crosstalk between the AhR and estrogen receptor (ER) signaling pathways in which the AhR inhibits estrogen-induced gene expression. The antiestrogenic activities of some AhR agonists are also being developed as drugs for clinical treatment of breast and endometrial cancers in women. Research on estrogen-dependent gene expression in various cancer cell lines is focused on analysis of several gene promoters to determine the mechanisms of ERa and ERb action. This includes several genes that are activated through interactions of the ER with Sp1 protein and other DNA-bound transcription factors.,Distinguished Professor||Distinguished Professor||Syd Kyle Chair,School of Veterinary Medicine and Biomedical Sciences||Biochemistry and Biophysics||Veterinary Physiology and Pharmacology,https://scholars.library.tamu.edu/vivo/display/nb20fdbd9
