Sprout Grant Winners 2011

Entrepreneurship is alive and well at Brandeis.

Last week, fourteen teams of Brandeis scientists presented their research to a panel of industry experts to compete for funding from the Brandeis University Virtual Incubator Sprout Grant Program.  The Virtual Incubator seeks to nurture and support entrepreneurial scientists at Brandeis by providing education, mentoring, networking and seed grants to help move their discoveries from the laboratory to the market.

Judges were impressed by the team presentations. The teams ranged from biologists who have projects that could be ready for licensing as early as next year, to computer science / IT entrepreneurship students with a web application that already has 1200 users.

“We were overwhelmed by the phenomenal proposals we received” says Irene Abrams, Associate Provost for Innovation.  “The response was incredible – with only a few weeks notice, 23 teams applied for Sprout Grants and 14 presented their proposals to the panel of judges.  I was impressed by the level of creativity among the applicants, and by the hard work the teams put into the presentations.  We only had $50,000, so we had to turn down many excellent applications, which we would have funded if we had more money.”

The 2011 winning projects are:

  • Generation Of A Rapid And Efficient Protein Knockout System, Lead Scientist:  Erin Jonasson (with Satoshi Yoshida)
  • Identification Of Molecules For Stabilizing DJ-1, A Protein Involved In Parkinson And Alzheimer Diseases. Lead Scientist: Joey Salisbury (with Brian Williams, Ala Nassar, Jeff Agar and Greg Petsko)
  • Targeting Oncogenic Ras For Protein Degradation, A Novel Approach To Therapy. Lead Scientist: Rory Coffey (with Marcus Long, Ruibao Ren, and Liz Hedstrom)
  • Identifying Pharmacological Chaperones that Promote Survival in Mouse Models of ALS, Lead Scientist: Jared Auclair (with Joey Salisbury, Dagmar Ringe, Greg Petsko, and Jeff Agar)
  • A Novel, Low Cost, Highly Sensitive Form Of Suppression PCR, Lead Scientist: Ken Sugino (with Sean O’Toole and Sacha Nelson)
  • Zen.Do, Team: Bill DeRusha, Joshua Silverman, Jason Urton (Computer Science)

Separating proteins and manipulating live cells using magnetic nanoparticles

Brandeis grad students Yue Pan (Chemistry) and Marcus Long (Biochemistry), together with Professors Lizbeth Hedstrom and Bing Xu, have synthesized novel 6 nm diameter magnetic nanobeads (comparable in size to a globular protein) and used them to separate specific proteins from a cell lysate and manipulate live cells. This work has just appeared online in the journal Chemical Science.

Selectively binding glutathione-S-transferase fusion proteins using
glutathione-decorated iron oxide nanoparticles and down-stream applications

These small, magnetic beads have numerous advantages over larger traditional glutathione-modified beads, including rapid purification, and ultra low non-specific binding. Importantly, both the purified GST and the protein of interest (POI) preserve their innate properties. They also demonstrate that functionalized iron oxide nanoparticles can be used to manipulate live cells. This work  establishes design principles for decorating magnetic nanoparticles that will ultimately should lead to a general and comprehensive platform for studying biological interactions and biological systems using a magnetic force.

Hedstrom named AAAS Fellow

Professor of Biology Liz Hedstrom has been named a fellow of the American Association for the Advancement of  Science (story on Brandeis NOW).

BrandeisNOW ran a follow-up profile on Liz. Moral: always ask your undergraduates whether they’ve thought about  going to grad school.

Back to class

Training the scholars in communicating science and improving the visibility of undergraduate research are key components of the Beckman Scholars program.

Novel IMPDH inhibitors are candidates for antibacterial drugs

The rise of multiply drug resistant bacteria creates an urgent need for new antibiotics and novel antibiotic targets.  IMPDH, a key enzyme in the biosynthesis of RNA/DNA precursors, is a target for cancer therapy that has not been exploited in antibiotic development. In their recent paper in Chemistry & Biology entitled Structural determinants of inhibitor selectivity in prokaryotic IMP dehydrogenases, Prof. Lizbeth Hedstrom and Brandeis postdocs Deviprasad Golapalli, Iain MacPherson and Suresh Gorla show that selective inhibitors of IMPDH from the protozoan parasite Cryptosporidium parvum also exhibit antibacterial activity. This work could lead to novel treatments for a wide variety of bacterial infections, including some of the most devastating and troubling human pathogens: Mycobacterium tuberculosis, drug-resistant Staphylococcus aureus (e.g. MRSA and VRSA), drug resistant Streptococcus pneumoniae and select agents such as Bacillus anthracis, Burkholderia mallei/pseudomallei and Francisella tularensis.  Importantly, these compounds will spare some commensal bacteria, which should decrease side effects and slow the rise of resistance.  This work suggests that IMPDH-targeted inhibitors can be developed into a new class of broader spectrum antibiotics.
