MPP PhD. Graduate Student Lauren Quattrochi received the Archambault Teaching Award's 1st Prize together with Michelle Fogerson of the Neuroscience Graduate Program for their course Drug Discovery: Treating Human Disease through Medicine.
The Reginald D. Archambault Award for Teaching Excellence recognizes, rewards, and promotes excellence in teaching in the Brown University summer programs. "This inspiring and thought provoking class stood out in that it covered an impressive amount material, yet the students were amazingly attentive, were asking deep questions, and were sincerely interested in learning as much as they could possibly absorb. Although the students were challenged considerably, learning appeared to remain fun and enjoyable." Read More.

More intestinal cells can absorb larger particles
Dr. Edith Mathiowitz - MPPB Dept published in Proceedings of the National Academy of Sciences (PNAS)
A new study reports that the small intestine uses more cells than scientists had realized to absorb microspheres large enough to contain therapeutic protein drugs, such as insulin. The finding in rats, published in the Proceedings of the National Academy of Sciences, is potentially good news for developing a means for oral delivery of such drugs. Read More.
Jeffrey Morgan is a Brown University professor and co-director of Brown's Center for Biomedical Engineering, who developed a new kind of petri dish that allows cells to grow in three-dimensional clusters, a step closer to actual tissue.
In a new study, a “bioadhesive” coating developed at Brown University significantly improved the intestinal absorption into the bloodstream of nanoparticles that someday could carry protein drugs such as insulin. Such a step is necessary for drugs taken by mouth, rather than injected directly into the blood. Read More.

MPPB Faculty Member, Dr. Elena Oancea, Awarded 2013 Salomon Award
Investigating the Function of a Novel Ultraviolet-Activated Pathway in Mice with Humanized Skin
Human skin is constantly exposed to solar ultraviolet radiation (UVR), a powerful environmental risk factor for skin cancer, which accounts for more than half of all human malignancies. Exposure to low doses of ultraviolet radiation results in increased skin pigmentation, while exposure to high doses correlates with skin cancer. The larger goal of Oancea's research is to understand the molecular processes that control the human skin's ability to detect and respond to UVR. Read More.

Phosphatase Inhibitor Design – A Unique Possibility for Brown University
The specific and reciprocal relationship between kinases and phosphatases controls most biological processes. Thus, when the balance is disrupted, the result is often disease. To date, efforts to modulate phosphate signaling to treat these diseases have focused on inhibiting kinases. However, it has recently become evident that the exquisite regulation of phosphorylation signaling is driven by tyrosine and serine/threonine phosphatases, rather than by kinases. Thus, one of the fastest growing areas of research is to identify potent, specific inhibitors of phosphatases. The Seed team, including Dr. Christopher Seto and Dr. Paul Williard, will combine expertise in biochemistry, structural biology, biophysics and synthetic organic chemistry in order to develop novel, potent inhibitors of phosphatases.

Study stops stress-based drug relapse in rats
In a new study in Neuron, scientists identified specific key steps in the chain of events that causes stress-related drug relapse. They identified the exact region of the brain where the events take place in rat models and showed that by blocking a step, they could prevent stress-related relapse. Read More.
In the paper published March 6, "Kappa Opioid Receptors Regulate Stress-Induced Cocaine Seeking and Synaptic Plasticity", researchers at Brown University and the University of Pennsylvania demonstrated specific steps in the sequence of neural events underlying stress-related drug relapse and showed that they take place within a brain region called the ventral tegmental area (VTA), which helps reinforce behaviors related to fulfilling basic needs.

Magnet sends lab capacity ‘through the roof’
As a crane lowered a powerful 3.8-ton magnet through the roof of the Laboratories for Molecular Medicine at 70 Ship St. today, Brown began work on deploying a powerful new tool for molecular biology research.
But much greater than the $2.9-million magnet itself is the potential of the research it will enable. Its job is to provide the incredibly strong magnetic field used in NMR spectroscopy. The technology allows chemists and biologists to determine the structure and motions of proteins down to the level of their individual atoms. Read More. Credit: David Orenstein, February 1, 2013

Study explains skin’s response to UVA light
Nicholas Bellono- MPP Graduate Student (Oancea Lab)
Last year, a team of researchers at Brown University discovered that certain skin cells use a light-sensitive receptor found outside of the eye to sense ultraviolet light and quickly begin pumping out melanin to protect against DNA damage. In a new study, lab members identify a key player in that biomolecular chain of events that could someday become a pharmacological target for improving this protective response. Read More.

Meeting of the Minds
Brown Institute for Brain Science members explore the mysteries of the brain. Lipscombe (left) has been collaborating with Professor of Medical Science Julie Kauer (right) to overcome a major technical obstacle that has impeded researchers' progress in the study of pain.
"No one has ever shown what happens when pain travels from, say, the finger to the spinal cord to the brain, and nobody really even knows if there are distinct pain pathways," says Kauer. "Exploring the basic cellular mechanisms would open the door to understanding and possibly addressing the physiological changes underlying a number of neurological and psychiatric disorders."
