Transport Of Bmaa Into Neurons And Astrocytes By System XC-, Rebecca Albano, Doug Lobner Jan 2018

Transport Of Bmaa Into Neurons And Astrocytes By System XC-, Rebecca Albano, Doug Lobner

Biomedical Sciences Faculty Research and Publications

The study of the mechanism of β-N-methylamino-l-alanine (BMAA) neurotoxicity originally focused on its effects at the N-methyl-d-aspartate (NMDA) receptor. In recent years, it has become clear that its mechanism of action is more complicated. First, there are certain cell types, such as motor neurons and cholinergic neurons, where the dominate mechanism of toxicity is through action at AMPA receptors. Second, even in cortical neurons where the primary mechanism of toxicity appears to be activation of NMDA receptors, there are other mechanisms involved. We found that along with NMDA receptors, activation of mGLuR5 receptors and effects on the …

Engineering A Molecular Missile For Pancreatic Cancer Detection: Vector Design, Sophia Castillo, Zhiwen Zhang Jan 2018

Engineering A Molecular Missile For Pancreatic Cancer Detection: Vector Design, Sophia Castillo, Zhiwen Zhang

Helene Lafrance Library Undergraduate Research Award

Pancreatic cancer, though rare, is expected to be the second-leading cause of cancer-related death by 2030 (Rahib et al., 2014). CA 19-9 is currently the most widely used biomarker for pancreatic cancer detection, but detection of CA 19-9 relies on the use of monoclonal antibodies, a technology that entails an expensive, lengthy, and ethically problematic manufacturing process. This paper presents the design of a DNA vector that can be used to program E. coli to produce a “molecular missile” that targets CA 19-9. Through the site-specific incorporation of an unnatural amino acid (L-DOPA), this peptide can be engineered to bind …
