Bruce,Riley,Professor,"My lab studies inner ear development in zebrafish. A prominent feature of our research is to investigate how cell-cell signaling and downstream gene-interactions control development. One project in the lab focuses on how cell signaling regulates ectodermal patterning during gastrulation to establish the otic placode, the precursor of the inner ear. Our recent work shows that localized Fgf signaling is especially critical for inducing formation of the otic placode, and members of the Pax2/5/8 family of transcription factors are important mediators of Fgf signaling. During later stages of inner ear development, we are exploring how sensory hair cells and neurons are regulated. Our studies address how these cells initially form, how they are genetically maintained, and how they become specialized for hearing vs. balance. We are also investigating how zebrafish can replace dead and damaged hair cells, an ability that mammals have lost. The inability to regenerate hair cells explains why humans show progressive irreversible hearing loss as we age. It is hoped that activating or augmenting human homologs of genes shown to operate in zebrafish might help restore hearing and balance in humans.",Professor,Biology,https://scholars.library.tamu.edu/vivo/display/n0dbb8253
Wayne,Versaw,Professor,"Compartmentalization of metabolic pathways and other cellular functions is a hallmark of eukaryotic cells. This feature is extreme in plants due to the presence of organelles not found in most other eukaryotes - plastids. Plastids are a diverse group of interrelated organelles that perform a wide range of metabolic functions including photosynthesis, nitrogen and sulfur assimilation and the synthesis of amino acids, starch and fatty acids. These functions are coordinated with metabolic processes in the cytosol through dynamic exchange of metabolites and ions across the plastid inner envelope membrane.
My lab is studying phosphate (Pi) transport processes that link the metabolic pathways in the plastid and cytosol. The concentrations of Pi in the cytosol and plastid stroma influence photosynthesis and the partitioning and storage of fixed carbon. Transporters involved in the movement of Pi across the plastid inner membrane include members of the pPT, PHT2 and PHT4 families. We are using genetics, cell biology, biochemistry and molecular physiology to investigate the function and physiological roles of these transporters. Recent findings suggest that some members of the PHT4 family are targeted to chloroplasts, whereas others function in heterotrophic plastids and one resides in the Golgi apparatus.
Other projects in the lab include the genetic and biochemical characterization of Pi transport processes in the filamentous fungus Neurospora crassa. Mutants with altered phosphate uptake properties have been isolated, and these have led to the identification of Pi transporter genes, as well as genes with putative regulatory functions.",Professor,Biology,https://scholars.library.tamu.edu/vivo/display/nea6b0d01
Uel,Mcmahan,Professor,"McMahan and his research group provide one of the cornerstones for Texas A&M's new Interdisciplinary Life Sciences Building and its related teaching and research efforts. His work focuses on how the nervous system's synapses form in the embryo and function in the adult in various animal species. It relies on high-resolution imaging, chemical characterization and experimental manipulation of specific macromolecules and organelles, which altogether provide insights unobtainable via any other approach. The findings bear directly on the problems of understanding the molecular basis of human brain diseases and restoring brain function after trauma.",Professor,Biology,https://scholars.library.tamu.edu/vivo/display/nfc3672e7
