Vishal,Gohil,Associate Professor,"Despite the fundamental role of the mitochondrion in cellular energy production and its involvement in numerous human diseases, we still do not know the function of nearly 20% of the known mitochondrial proteins. My laboratory applies genomic, genetic, and biochemical tools to uncover the role of these uncharacterized proteins in the mitochondrial respiratory chain (MRC) biogenesis. MRC is the main site of cellular respiration and energy production and since the core components of the MRC are evolutionarily conserved, we reason that the assembly factors required to build the MRC should also be conserved. Therefore, we utilize multiple models systems, including yeast, zebrafish, and human cell lines, to determine the role of these conserved, uncharacterized mitochondrial proteins in bioenergetics, organismal development, and human disease pathogenesis.
Another poorly understood aspect of the mitochondrial energy metabolism is the role of phospholipids in maintaining the structural and functional integrity of the MRC. Although it is well known that the MRC is localized in the inner mitochondrial membrane, how the unique lipid milieu of the mitochondrial membrane influences the assembly and activity of the MRC is not fully understood. We have constructed yeast mutants with defined mitochondrial phospholipid compositions to systematically determine each lipid's role in MRC assembly and activity. Ultimately, defining the roles of mitochondrial proteins and phospholipids will allow us to develop better diagnostic and therapeutic options for human disorders resulting from mitochondrial dysfunction.",Faculty Affiliate||Assistant Professor,Energy Institute||Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/n03100e49
Hubert,Amrein,Professor,"My broad research interests are concerned with the sensory perception of the external chemical world. The central questions investigated in our laboratory are concerned with how animals detect and discriminate among the thousands of different chemical signals that ""flood"" the olfactory and taste organs. Our laboratory uses Drosophila as a model to study these problems because the Drosophilachemosensory systems are structurally and functionally very similar to those of mammals, yet they are smaller and somewhat less complex, which makes them excellent models to investigate the molecular and neural basis of olfaction and taste.",Senior Associate Dean of Research||Professor||Professor,Cell Biology and Genetics||School of Medicine||Nutrition,https://scholars.library.tamu.edu/vivo/display/n0839ec95

Xiuren,Zhang,Professor,"Our laboratory focuses on systemic analysis of biochemical, molecular and biological functions of AGO family proteins (AGOs-mics) in genetically tractable Arabidopsis and economically important crops (i.e. rice). We'd like to identify the small RNAs, mRNA targets and protein components which associate with these AGOs. We will study protein/RNA and protein/protein interactions in these RISC assembly events. Our goal is to understand how these AGOs are functionally specialized or redundant corresponding to endogenous development cues and external environmental stimuli. Particularly, we'd like to learn how plants reprogram their gene expression through the small RNAs and AGOs to construct a new cellular niche in responses to environmental challenges and biotic stresses.
Another aspect of our research involves host/virus interaction. Plants take advantage of RNA silencing pathways to defend themselves from exogenous nucleic acid invaders (i.e. viruses). As an anti-host defense mechanism, viruses encode suppressors that can block RNA silencing responses. We have recently demonstrated that CMV 2b disables AGO1 cleavage activity to inhibit RNA silencing and to counter host defense. We are now extending our study to suppressors of several other viruses and the molecular mechanisms of their suppression.",Associate Professor,Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/n220933ad

Travis,Hein,Professor,"My laboratory studies the regulation of microvascular function at the level of arterioles in the retinal and coronary circulations. Sufficient blood flow supply of oxygen and nutrients to tissues to maintain normal function is controlled in large part by changes in the diameter of arterioles. Vasoconstriction or vasodilation of these small arteries will decrease or increase blood flow and nutrient delivery to the tissue, respectively. Two key chemical factors that are produced within the endothelial cells of blood vessels to control their diameter are nitric oxide (NO), a vasodilator, and endothelin-1, a vasoconstrictor. An imbalance in the production and/or release of these vasoactive factors has been implicated in the early stages of several cardiovascular diseases, but the underlying mechanisms contributing to these pathophysiological changes remain unclear. To address this knowledge gap, our research focuses on identifying cellular and molecular mechanisms that contribute to the vasomotor responses of arterioles to NO and endothelin-1 under conditions of health and disease. Current approaches that we use to investigate these mechanisms in the microcirculation include isolated and perfused arterioles, cultured vascular endothelial and smooth muscle cells, biochemical and molecular techniques (for detection of NO, superoxide anion, protein, and mRNA in arterioles), pharmacological and silencing RNA (siRNA) treatments, and blood flow velocity assessment via Doppler ultrasound.",Professor,Medical Physiology,https://scholars.library.tamu.edu/vivo/display/n45051e1b

James,Sacchettini,Professor,"My lab uses X-ray crystallography to better understand the relationship between proteins and ligands. Tiny differences in the structure of a molecule can radically change the interaction between a protein and ligand and we are only begining to understand how many factors play a role in this interaction. By manipulating the individual components of a compound it is possible to create a chemical that binds to the protein better than the natural substrate, and prevent the natural reaction from occurring. This is the basis for rational drug design. Our efforts have lead us to collaborations with other labs and scientists in many disciplines as our approach to directed compound design has applications not only in basic research but also in pesticide development, health research and clinical research.",Professor,Biochemistry and Biophysics,https://scholars.library.tamu.edu/vivo/display/n90385563

Lih,Kuo,Regents Professor,"My research focuses on the physiological and pathophysiological regulation of coronary and retinal microcirculation. In the circulatory system, the amount of blood delivered to each tissue can be regulated by the activity of arterial microvessels (<100 m in diameter). Changes in vascular tone, i.e., constriction or dilation of these microvessels, will decrease or increase blood supply to the tissue, respectively. However, the mechanisms involved in the regulation of vascular tone are not completely understood. Our current research focuses on the regulation of microvascular tone by hemodynamic (e.g., pressure and shear stress), metabolic (e.g., adenosine, osmolarity, K+, pH, pO2) and neural (adrenergic receptors) factors. To have an integrative view on the flow regulation, this basic information are reconstructed using mathematical model and computer simulation technology. This research provides a basic foundation critical to our understanding of blood flow regulation in the microvascular network under normal and disease states.",Regents Professor,Medical Physiology,https://scholars.library.tamu.edu/vivo/display/nbc742025
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

The laboratory also employs molecular biology, cell biology, and mouse genetic technologies to study how aberrant FGF signals promote tumor initiation, progression, and metastasis. In addition, how environmental factors contribute to tumorigenesis and congenital birth defects by modulating FGF signal intensity and specificity is also under the scope of our research interests.",Professor,Institute of Biosciences and Technology,https://scholars.library.tamu.edu/vivo/display/nd5ef47ba

Paul,Hardin,Distinguished Professor,"A diverse array of organisms including prokaryotic and eukaryotic microbes, plants, and animals display daily rhythms in physiology, metabolism and/or behavior. These rhythms are not passively driven by environmental cycles of light and temperature, but are actively controlled by endogenous circadian clocks that are set by environmental cycles, keep time in the absence of environmental cues, and activate overt physiological, metabolic and behavioral rhythms at the appropriate time of day. This remarkable conservation of circadian clock function through evolution suggests that maintaining synchrony with the environment is of fundamental importance. Our understanding of the circadian clock is particularly important for human health and well-being. The clearest examples of circadian clock dysfunction are those that result in abnormal sleep-wake cycles, but clock disturbances are also associated with other ailments including epilepsy, cerebrovascular disease, depression, and seasonal affective disorder. The realization that disorders of the sleep-wake cycle such as Familial Advanced Sleep Phase Syndrome can result from alterations in clock gene function underscores the clinical importance of understanding the molecular organization of the circadian system.
Work in my laboratory focuses on defining the molecular mechanisms that drive circadian clock function in the fruit fly, Drosophila melanogaster. We previously found that the core timekeeping mechanism is based on core and interlocked transcriptional feedback loops. Our studies currently focus on (1) defining post-translational regulatory mechanisms that operate in the core loop to set the 24 hour period, (2) determining whether interlocked loops are important for circadian timekeeping and/or output, (3) understanding how circadian oscillator cells are determined during development, and (4) defining mechanisms that control rhythms in olfactory and gustatory physiology and behavior.",Distinguished Professor,Biology,https://scholars.library.tamu.edu/vivo/display/nf27056c4
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
