Shinji Rho named 2020 Goldwater Scholar

Shinji Rho, Brandeis UndergraduateCongratulations to Shinji Rho who has been named a 2020 Goldwater Scholar.  The Goldwater Scholarship is a national scholarship designed to encourage outstanding students in their sophomore and junior year to pursue research careers in the fields of mathematics, the natural sciences, and engineering.

Shinji is currently a junior. Her project at Brandeis is on a transcriptional activator Gal4, which binds to upstream activating sequence (UAS) sites in the yeast genome to promote transcription. Previous studies have shown that dwell time of Gal4 on the UAS is significantly longer in purified systems than in cells. She is interested in finding the reason for this dwell time difference using single-molecule light microscopy. The findings of her project will provide a more realistic view of how transcription activation system behaves when nuclear proteins are present. 

Shinji plans to obtain a PhD degree in cancer biology, ultimately conducting research on developing more accurate and easily accessible breast cancer diagnosis methods.

Her mentor is Jeff Gelles, Aron and Imre Tauber Professor of Biochemistry and Molecular Pharmacology.

 

SPROUT and I-Corps Applications are Open

Sprout logoThe Brandeis Innovation SPROUT and I-Corps programs offer support for bench and non-bench research. Both programs offer funding in different amounts, mentorship, training and help in further exploring the commercial potential of inventions. SPROUT supports bench research, while I-Corps emphasizes training for both bench and non-bench researchers in developing the commercial potential of discoveries, with small grants and extensive training programs. You can apply to one or both programs.

  • If you have a technology / solution that you have started developing and you would like to get funding for it via SPROUT and/or I-Corps, then please complete this form
  • If you do not already have a technology, then you can complete this form to qualify for the I-Corps training program and be matched with a team

SPROUT teams will get the chance to qualify for up to $30,000 in funding. The I-Corps program provides entrepreneurial training and covers the core of commercializing a technology or building a startup. It comes with an NSF $750 travel and training stipend and an NSF I-Corps certificate/digital badge.

Goode, Gelles and Kondev labs synergize in discovery of a new synergistic actin depolymerization mechanism

All animal and plant cells contain a highly elaborate system of filamentous protein polymers called the actin cytoskeleton, a scaffold that can be rapidly transformed to alter a cell’s shape and function. A critical step in reconfiguring this scaffold is the rapid disassembly (or turnover) of the actin filaments. But how is this achieved? It has long been known that the protein Cofilin plays a central role in this process, but it has been unclear how Cofilin achieves this feat. Cofilin can sever actin filaments into smaller fragments to promote their disassembly, but whether it also catalyzes subunit dissociation from filament ends has remained uncertain and controversial. Until now, this problem has been difficult to address because of limitations in directly observing Cofilin’s biochemical effects at filament ends. However, a new study published in Nature Communications led by postdoctoral associate Dr. Shashank Shekhar, jointly mentored by Bruce Goode, Jeff Gelles and Jane Kondev, uses microfluidics-assisted single molecule TIRF imaging to tackle the problem.

The new study shows that Cofilin and one other protein (Srv2/CAP) intimately collaborate at one end of the actin filament to accelerate subunit dissociation by over 300-fold! These are the fastest rates of actin depolymerization ever observed. Further, these results establish a new paradigm in which a protein that decorates filament sides (Cofilin) works in concert with a protein that binds to filament ends (Srv2/CAP) to produce an activity that is orders of magnitude stronger than the that of either protein alone.

The work was funded by National Institutes of Health, National Science Foundation MRSEC and Simons Foundation grant.

The Fall 2019 issue of Brandeis Magazine features a cover story on Professor of Biochemistry and HHMI Investigator Dorothee Kern.  The article describes Kern’s trajectory from her youth and education in the former East Germany to her current research and teaching at Brandeis to her co-founding of Relay Therapeutics, a Cambridge company pioneering new approaches to anti-cancer drug discovery.

 

Alumni and Student Researchers Wow Crowd at 2019 SciFest

With a new alumni symposium in the morning and a poster session filling three floors of the Science Center atrium in the afternoon, this year’s SciFest IX set a new standard for Brandeis Science’s annual celebration of undergraduate research.

Since 2011, a poster session featuring the results from ongoing projects belonging to undergraduates doing science research has been the high point of summer in the Division of Science at Brandeis. This year, for the first time, we invited Brandeis alumni scientists to speak in a morning symposium entitled “A Celebration of Brandeis’ Undergraduate Science Education”, including:

Students and faculty in the audience were treated to a history of Brandeis and reflections on many of the Brandeis professors and courses that set them on their career path and whose influence persists to the present in how they approach their science, and on lessons they learned that continue to guide their work.

After lunch in the campus center, the crowd climbed up to the Shapiro Science Center for the poster session. 123 students presented 117 posters on topics from high-energy physics to biomaterials and from quantum chemistry to fruit fly behavior. As President Ron Liebowitz noted in an email to the Science community after the event:

The energy in Shapiro during the poster session was electric.  The students’ confidence and excitement over sharing their research can only give us great optimism about the future: they are “all in” when it comes to doing basic research, but also seeing how such research can be applied in the name of helping others.

Many of the posters can be found in the hallway in Gerstenzang – look for them when classes start again in a few weeks!

Jeff Gelles elected to American Academy of Arts and Sciences

Jeff Gelles, the Aron and Imre Tauber Professor of Biochemistry and Molecular Pharmacology, has been elected to the American Academy of Arts and Sciences. He was among the  more than 200 outstanding individuals that were elected to the Academy in 2019 and announced on April 17.

The Gelles lab studies “little engines” or the nanometer-sized machines made of protein, RNA, and DNA molecules that carry out the essential processes in living cells.  The lab uses single-molecule light microscopy methods to study the functional mechanisms of these macromolecular complexes in cytoskeletal function, transcription and transcription regulation, and RNA processing.

Founded in 17890, the Academy recognizes the outstanding achievements of individuals in academia, the arts, business, government, and public affairs.
