Chemist Arturo Vegas wins $1.4 million NIH grant to develop therapies that intervene at early stage of disease












Dr. Arturo Vegas was recently featured in BU Today for his research into Type 1 Diabetes. The full article is called “New Targets to Treat Type 1 Diabetes” and there’s an excerpt from the article by Barbara Moran is below.

For more information about Dr. Vegas visit his Faculty Page and for more on his research group visit the Vegas Group Page.

“Type 1 diabetes is rare but devastating. A person’s own immune system attacks the pancreas, destroying insulin-producing tissue and the body’s ability to regulate blood sugar. About five percent of people with diabetes—approximately 1.25 million Americans—have this form of the disease, according to the American Diabetes Association. Unregulated blood sugar can lead to blindness, kidney failure, and death.

Scientists aren’t sure what causes type 1 diabetes, though they suspect that a genetic predisposition, combined with an environmental trigger, causes a sudden disruption in the immune system that causes it to attack the body’s own tissue. The only treatment is a lifetime of careful blood sugar monitoring, with insulin injections as needed.

But what if there were a way to block the immune system before the damage was done, preserving at least some of the pancreas’ ability to produce insulin? That’s the goal of Arturo Vegas, a Boston University College of Arts & Sciences assistant professor of chemistry, whose lab combines biology, chemistry, materials science, and engineering to develop targeted therapies for complex diseases like diabetes. He recently was awarded a prestigious $1.4 million Type 1 Diabetes Pathfinder Award from the National Institutes of Health (NIH) to pursue the work.”


Congratulations Dr. Vegas!

NSF Graduate Fellow Joins Straub Group

April 24th, 2015 in Front Page, Graduate

Former Chemistry REU student George Pantelopulos returns as Graduate Student

Former Chemistry REU student, George Pantelopulos, returns as Graduate Student

2015 NSF Graduate Research Fellowship Program (GRFP) award recipient, George Pantelopulos, has joined Chemistry to do his proposed graduate research in theoretical chemistry with Prof. John Straub and his group.   George aims  to model the kinetics of phase transitions in a system of components (lipids and cholesterol) commonly found in eukaryotic cell membranes using the Generalized ReplicaExchange Method (gREM) developed by the Straub group and constructing a Markov State Model (MSM) of a mixed bilayer.  George believes that his study will yield a statistically detailed model of the thermodynamics and kinetics of mixed bilayer phases, something which has been sought for years via experimental techniques and previously out-of-reach for standard simulation methods.

George is no stranger to BU Chemistry.  In 2013 he was one of the 10 students selected for Chemistry’s NSF site Research Experience for Undergraduates (REU) program.  At the time, he was at the Community College of Philadelphia.   During his summer REU program here, he  helped to synthesize nanohoops of high electron density, which were hypothesized to serve as high performance coatings for solar cells. In Fall 2013 he transferred to Temple University (Philadelphia, PA), where he did research with Prof. Vincent Voelz on simulation studies of the p53-MDM2 complex.  MDM2 is an ubiquitin ligase protein which downregulates the tumor suppressor protein p53.  As such, inhibition of the p53-MDM2 complex is a major goal in targeted cancer therapy research.

In addition to chemistry, George’s interests are broad and varied.   He has a strong commitment to community service and have volunteered with such organizations as TeenSHARP, a weekend educational program for minority students in Philadelphia and Camden schools, where he was a science instructor and Habitat for Humanity.

NIH Funds Alzheimer’s Research Addressing Fundamental Questions

March 4th, 2015 in Front Page, Research

Straub_ThirumalaiThe National Institutes of Health (NIH) has awarded a 4-­year grant to computational chemists, Professor John Straub and his colleague at the University of Maryland (UMD), Professor Devarajan (Dave) Thirumulai, on “Probing the role of membrane and cholesterol on APP‐C99 structure and dynamics.”  Protein aggregation in the brain is linked to Alzheimer’s Disease (AD).  This neurodegenerative disorder accounts for nearly 50 percent of all cases of senile dementia, is the third leading cause of death in the elderly population, and – devastatingly ­‐ is presently incurable.  Familial mutations in the Amyloid Precursor Protein (APP), from which the amyloid β (Aβ) protein associated with AD is derived, have been linked with the early onset of amyloid disease.


Predicted structure of the transmembrane domain of the APP homodimer may provide critical insight into the genesis of Aβ protein and the evolution of AD.

This computational and theoretical research collaboration between the Straub and Thirumalai groups, augmented by synergistic experimental research collaborations, will explore the structure and dynamics of the 99 amino acid transmembrane fragment of APP (APP‐C99) in membrane environments. This work will have high impact because it has the potential to answer outstanding questions in the field that remain unresolved as a result of conflicting conclusions of experimental studies.  By providing novel insights into the dependence  of APP structure on familial AD mutations, membrane composition, and interactions with cholesterol, the work will advance the ability to develop preventive or early stage therapeutics for AD.

February 26th, 2015 in Faculty, Front Page


Professor Sean Elliott

Professor Sean Elliott

Professor Sean Elliott, who joined the Department of Chemistry in 2002 and was tenured in 2008, has been promoted to full Professor.

Professor Elliott’s research is at the intersection of biochemical processes and electron-transfer chemistry.  By studying how electrons are moved within and between proteins in Biology, he and his group provide a novel, quantitative view of redox regulation, homeostasis, and oxidative stress. Using protein film electrochemisry (PFE), they probe how redox equivalents are stored, manipulated, and transferred in enzymes, in electron-transfer proteins, and in chains of electron-transfer proteins. They have addressed projects that reflect their interests in heme- and ironsulfur cluster-containing electron transfer proteins and enzymes. Professor Elliott has successfully developed new electrochemical methods for addressing questions of enzyme and metalloprotein function to monitor the flow of electrons themselves. Simultaneously, he has a growing research portfolio in the application of Bioinformatics to problems in Metals in Biology. Using sequence similarity network (SSN), he and his group examine the biological diversity of various multi-heme, iron-sulfur cluster and non-heme iron-dependent enzymes and proteins. Further, his group uses PFE and biophysical techniques to investigate the catalytic chemistry of multi-heme enzymes and bacterial peroxidases extensively.

Professor Elliott has received a Scialog Award from the Research Corporation for the Advancement of Science, a Smith Family Young Investigator Award, and the NSF-CAREER Award.  In addition to his excellence in research, he has been recognized by Boston University for his educational skills with a Gitner Award for Distinguished Teaching and for advising with the Templeton Award for Student Advising.
