yo!
Alice Macdonald is a sophomore in Biological Engineering. I live at French House[1], work in the Voldman lab[2], and I am taking BE.109, BE.320, BE.180, and 21F.341. I like watching movies and TV, editing wikis, and I am a strong advocate of pants.

Module Four Research Proposal
Project Overview: We want to mediate cell adhesin by engineering changes in integrins in hopes of better understanding cell response to binding materials. We want to make integrins that bind more or less strongly to materials. Natural ligands for integrins are fibronectin, collagen, and laminin. We could engineer a novel integrin to bind to a different ligand, perhaps a sythetic material or scaffold.
Background Information: Integrins are membrane bound proteins important for cell adhesion to ECM (extra cellular matrix) and also for signal transduction. They are involved in signaling that leads to differentiation, migration, cell growth, and apoptosis. Integrins are also connected to cancer as mutated integrin genes have been found in some types of cancer and integrins may be involved in metastasis.
Statement of Research Proposal and Goals: We propose to create novel integrins using a targeted mutagenesis approach. Our goals are to create integrins with different binding properties and then study their interactions with synthetic scaffolds used in tissue engineering. Or we could use the mutated integrins to study differentiation - we could examine how a very weakly or tightly binding integrin affects differentiation of stem cells.
Project Details and Methods: coming soon
Predicted Outcomes: We predict that changing structure of integrin will change the way the cell can interact with a material. Some engineered integrins will bind tighter to a certain surface than their naturally occurring counterparts and some engineered integrins will bind less tightly than their naturally occurring counterparts.
Necessary Ressources: coming soon
