Alzheimer’s Disease (AD) is characterized by Beta-Amyloid (Aβ) plaques within the brain. Aβ peptides are produced by the cleavage of Amyloid Precursor Protein (APP). Our lab has previously discovered a novel pathway for APP internalization mediated by ADP-ribosylation factor 6 (Arf6). This pathway resembles macropinocytosis, transporting cell surface APP directly to lysosomes, a possible site for Aβ production. We set out to characterize the effectors downstream of Arf6. In SN56 and N2A cells we co-transfected HA-tagged APP (to label cell-surface APP) with compartment markers, to visualize APP trafficking. We used dominant negative and constitutively active mutants, pharmacological inhibitors, and siRNA …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The field of regenerative medicine seeks to create replacement tissues and organs, both to repair deficiencies in biological function and to treat structural damage caused by injury. Scaffoldings mimicking extracellular matrix (ECM), the structure to which cells attach to form tissues, have been developed from synthetic polymers and also been prepared by decellularizing adult tissue. However, the structure of ECM undergoes significant remodeling during natural tissue repair, suggesting that ECM-replacement constructs that mirror developing tissues may promote better regeneration than those modeled on adult tissues. This work investigated the effectiveness of a method of viewing the extracellular matrix of developing …

Vibrational spectroscopy, including Raman spectroscopy, has been widely used over the last few years to explore potential biomedical applications. Indeed, Raman spectroscopy has been demonstrated to be a powerful non-invasive tool in cancer diagnosis and monitoring. In confocal microscopic mode, the technique is also a molecularly specific analytical tool with optical resolution which has potential applications in subcellular analysis of biochemical processes, and therefore as an in vitro screening tool of the efficacy and mode of action of, for example, chemotherapeutic agents.
In order to demonstrate and explore the potential in this field, established, model chemotherapeutic agents can be valuable. …
