Department of Cell Biology

Overview

Research in the Department of Cell Biology is focused on understanding molecular mechanisms of gene regulation in eukaryotic cells. Using mammalian cells, yeast, viruses, fruit flies and transgenic mice, we are investigating mechanisms of DNA replication and repair, control of the cell cycle and apoptosis, roles for transcriptional regulation and chromatin structure in gene expression, RNA processing, intracellular trafficking, membrane fusion and budding, mechanisms of generating antibody diversity, and the functions of cell surface sugars.

Dachuan

The Department of Cell Biology would like to congratulate Dr. Dachuan Zhang, a Postdoctoral Fellow in the laboratory of Dr. Paul Frenette, who has been awarded of the 2016 Julius Marmur Research Awards for his proposal, “Neutrophil aging is regulated by the microbiome".

 

will

Welcome New Cell Biology Faculty! Britta Will, Ph.D. was appointed assistant professor in the Departments of Medicine and Cell Biology in December 2015.
Dr. Will received her Ph.D. training at Harvard Medical School and the University of Freiburg, Germany. Prior to this appointment, Britta did outstanding research on the regulation of normal hematopoietic and malignant stem cell function under Dr. Ulrich Steidl’s mentorship.
Her research program dissects how age-related changes in gene-regulatory mechanisms contribute to hematopoietic stem cell failure and malignant transformation and exploits a combination of genetic mouse models, primary human specimen and cutting-edge molecular and cell biological assay systems.
Dr. Will’s laboratory is located in Room 401 of the Chanin Building. [web page]

Inaugural Honoree — The American Association of Immunologists (AAI) has selected Dr. Matthew Scharff as the first-ever recipient of its inaugural 2015 AAI-BioLegend Herzenberg Award, which he will receive this spring during a special session at IMMUNOLOGY2015™. The honor recognizes an individual who has made exemplary research contributions to the field of B cell biology. Dr. Scharff is world-renowned as a pioneer in the development and application of monoclonal antibodies, which have become a cornerstone in biomedical research. He is distinguished professor of Cell Biology and of Medicine, as well as the Harry Eagle Chair in Cancer Research/National Women's Division and faculty supervisor of the Hybridoma and Tissue Culture Facility. The AAI-BioLegend Herzenberg Award was established, with support from BioLegend to honor the memory of AAI member Dr. Leonard A. Herzenberg.

Stanley

On 5/6/2015, Dr. Pamela Stanley gave a lecture in the NIH Director's Wednesday Afternoon Lecture Series (WALS), which is the highest-profile lecture program at the NIH. Her lecture was entitled “ Glycans that regulate development and notch signaling”.

 

Birshtein

Dr. Barbara Birshtein has been selected as this year’s recipient of the LaDonne H. Shulman Award for Excellence in Teaching. The recipient of this award is nominated and selected by the graduate students as a faculty member who has demonstrated exemplary skill in teaching and mentoring.
Of special note: This is the second time that Barbara has received this award!
Congratulations to Barbara on this very appropriate recognition of her dedication and teaching and mentoring skills by the graduate students.
 

 

Election to fellow is an honor bestowed upon American Association for the Advancement of Science (AAAS) members by their peers. In 2014, 401 AAAS members were awarded this honor because of their scientifically or socially distinguished efforts to advance science or its applications. Among the six AECOM faculty members who received this distinction, three are members of the Department of Cell Biology.

A novel class of allosteric IDH1 inhibitors is effective against multiple clinically relevant mutants, promoting differentiation of AML blasts and stem-like cells and restoring DNA cytosine methylation patterns.
