Ductal carcinoma in situ (DCIS) accounts for 20% of all breast cancer diagnoses in the United States. Graduate student Eline Boghaer used lattice-based computational modeling to explore the progression between classes of DCIS.
Prof. Brynildsen is a recipient of an NSF CAREER award that focuses on studying nitric oxide stress in bacteria with approaches adopted from metabolic engineering to discover novel antivirulence therapies. Depicted above, a simplified diagram of the Escherichia coli nitric oxide response network.
The size of a typical eukaryotic cell is usually of the order of ~10 μm. However, some cell types grow to very large sizes, up to 1 mm. Graduate student Marina Feric in the Brangwynne lab has used microrheology and quantitative imaging to show that large nuclei contain an elastic F-actin scaffold that mechanically stabilizes them against gravitational forces.
