Dr. Susan Shao was just named a 2018 Vallee Foundation Scholar. Congratulations, Susan! The Vallee Foundation was created in 1996 by Bert and Kuggie Vallee, and its mission is to support outstanding young scientists who strive to advance their field with innovative and cutting edge techniques. The Foundation focuses on cultivating ingenuity and leadership through its worldwide programs. In addition to the Vallee Scholars program, the Foundation offers several programs to enhance research, including the Visiting Professorship Program and trainee travel fellowships. Susan's research focuses on the molecular mechanisms of protein quality control that are critical for maintaining cellular homeostasis; by studying the fate of newly synthesized proteins using biochemistry, structural biology, and cell biology approaches, her research will contribute to a better understanding of human diseases such as neurodegeneration and cancer.

The Brugge lab has shown that the calcium channel protein, TRPA1, aids in tumor survival and has proposed targeting this protein as a potential cancer treatment. In a recent publication in Cancer Cell, the Brugge lab shows how TRPA1, normally used by humans as a sensor for environmental irritants such as wasabi or spicy mustard, is co-opted by tumor cells. Some cancers express TRPA1 in high levels, creating a defense mechanism against reactive oxygen species (ROS), thereby inhibiting programmed cell death and making cancer cells less vulnerable to radiation and chemotherapy. This research adds to a growing body of evidence that cancer cell survival can be improved by anti-oxidants. By further elucidating the biological mechanisms of TRPA1 function, the Brugge lab hopes to gain a better understanding of how this protein could be targeted in clinical cancer treatments.

Dr. Steve Liberles was one of only 19 researchers across the country who were named 2018 HHMI Investigators. He has made groundbreaking discoveries in the area of neural sensory systems, with his most research focused on the role of the vagus nerve and the many basic bodily functions it regulates, including breathing, satiety, and blood pressure. Read more about his research here. Overall, the 2018 Investigator class was well-represented by Cell Biology alums; other awardees include Dr. Gia Voeltz (former Rapoport lab postdoc) and Samara Reck-Peterson (former Cell Bio faculty member).
Congratulations to Steve, Gia, and Sam!
Alban Ordureau, a postdoc in the Harper lab, has developed a proteomics method that allows for the dynamics of PARKIN-dependent mitochondrial ubiquitylation to be followed with unprecedented preision and in a site-specific manner. The approach employed targeted proteomics of ubiquitylation sites in 15 PARKIN targets, allowing digital snapshots of PARKIN activity. This system was used to monitor PARKIN activity in stem cell-derived cortical and dopaminergic neurons, and to examine mechanistic aspects of the pathway.
The Kirchhausen lab, in collaboration with Nobel laureate and Janelia group leader Eric Betzig, has developed a microscope capable of capturing 3-D images and videos of cells inside living organisms in unprecedented detail. To enable such high resolution images, researchers combined two technologies: lattice light sheet microscopy, which Betzig developed in the early 2010s, and adaptive optics, a technique borrowed from astronomy. This work was published in a new study in the April 20, 2018 issue of Science. To learn more, read here.
Dr. Wade Harper, Chair of Cell Biology and the Bert and Natalie Vallee Professor of Molecular Pathology, was just named a 2018 Fellow of the American Academy of Arts and Sciences. The mission of the Academy is to champion scholarship, civil dialogue, and useful knowledge. It is one of the country’s oldest learned societies and independent policy research centers, and it convenes leaders from the academic, business, and government sectors to respond to the challenges facing the nation and the world. Other notables named to this year's class include several Harvard-affiliated researchers, as well as Barack Obama and Sonia Sotomayor! Congrats to Wade!
Dr. Yang Shi, Merton Bernfield Professor of Neonatology at Boston Children's Hospital and Professor of Cell Biology at HMS, was appointed the C.H. Waddington Professor of Pediatrics, effective January 1, 2018. This endowed chair appointment was bestowed by the Dean of the Faculty of Medicine at HMS, with advice of the Trustees of Boston Children's hospital. Congratulations Yang!
Nick Bodnar, an MD/PhD student from the Rapoport lab, was one of 13 graduate students selected to receive a 2018 Harold M. Weintraub Graduate Student Award, which recognizes outstanding achievement in graduate studies in the biological sciences. Winners were selected based on the quality, originality, and significance of their work. Nick is a member of the HMS Biological and Biomedical Sciences graduate program. Congratulations Nick!
In a short movie produced by HMS' Office of Communications and External Relations, Fred Goldberg reminisces about his remarkable career--touching on the excitement of research, his trainees and colleagues, and the payoffs of asking basic, fundamental biological questions.
