Systems Biology Interest Group: Learning to rewire cells
Systems Biology Interest Group
Traditionally, biology has focused on deconstructing and mapping the molecular systems that carryout complex regulatory functions. We still lack, however, a more global understanding of the design principles governing how cells solve problems and make regulatory decisions. To address this problem, we have been complementing deconstructionist approaches with synthetic approaches in which we ask how to build molecular systems that can execute particular regulatory tasks. Are there a limited number of molecular algorithms that evolution can use to solve common physiological tasks? If so, can we ...

Sounds in Silence: How the Cochlea Promotes Refinement of Auditory Circuits before Hearing Onset
NIH Neuroscience Seminar Series
Robert Wenthold Memorial Lecture
Dr. Bergles lab is interested in understanding the mechanisms by which neurons and glial cells interact to support normal communication in the nervous system. Neurons transmit information at specialized synaptic junctions, points of contact where action potentials elicit the release of a chemical neurotransmitter. Neurotransmission at excitatory synapses involves the vesicular release of glutamate, diffusion and binding of glutamate to various receptors, and uptake of glutamate by transporters. Transporters are critical for ensuring that receptors are availab...

Special Tuesday Lecture, NIH Director's Wednesday Afternoon Lecture Series
Julie Theriot is the Benjamin D. Hall Endowed Chair in Basic Life Sciences and a Howard Hughes Medical Institute investigator in the Department of Biology at the University of Washington. Her lab explores the mechanics and dynamics of how cells organize themselves to create their own structures and shapes. She studies an unusually wide variety of cell types and model systems in order to gain a broad conceptual understanding of the organizational rules that give rise to cell structure and coordinated movement. This work has important implications for understanding host-pathogen interactions, the function of immune cells, a...

The biosynthesis of lipoic acid: a saga of death, destruction, and rebirth
NIH Director's Wednesday Afternoon Lecture Series
Research in the Booker Lab focuses on understanding how Nature harnesses the power of radicals to effect kinetically challenging enzymatic reactions, many of which are critical to proper cellular functioning. Much of the lab ’ s work has centered around the enzymatic use of S-adenosylmethionine and iron-sulfur clusters to generate a 5 ’ -deoxyadenosyl 5 ’ -radical, used as a key intermediate by members of the radical S-adenosylmethionine (SAM) superfamily to catalyze over 60 different reaction types. One major interest of the Booker Lab is the use of radical SAM chemi...

A cheaper way to light up smartphones and TVs, no asteroid required
Chemists have found a cheaper way to light up smartphone and TV screens -- using copper rather than iridium -- which could save manufacturers and consumers money without affecting visual quality. Iridium is one of the rarest elements on Earth, its origins possibly a millions-year-old asteroid; ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

NIDCR Grand Rounds: Mechanoregeneration via Biomaterials
NIDCR Clinical Research Fellowship Grand Rounds
Dr. David Mooney ’ s research is based on the question, “ How do mammalian cells receive information from the materials in their environment? ” By using the tools of bioengineering and cell and molecular biology, he studies the mechanisms by which chemical or mechanical signals are sensed by cells, and how these signals alter cellular proliferation and specialization to either promote tissue growth or destruction. His research results inform the design and synthesis of new biomaterials that regulate the gene expression of interacting cells for a variety of tissue engine...

Everything you wanted to know about microtubules but were afraid to ask
NIH Director's Seminar Series
Dr. Roll-Mecak will discuss the research of the Laboratory of Cell Biology and Biophysics Section, NINDS. The title of her talk is " Everything you wanted to know about microtubules but were afraid to ask " .
In addition to providing structural support, microtubules form a complex and dynamic intracellular " highway " that delivers molecular cargo from one end of the cell to another - which in the case of neuronal cells can span several feet. Given the continually changing cell physiology, this delivery system undergoes constant remodeling as cargo is transported to different destinations with...
