Role Of Integrase-Pp2a Interaction In Human T-Cell Leukemia Virus Type-1 Replication And Pathogenesis, Shayna Turbin
Senior Honors Papers / Undergraduate Theses
Human T-cell leukemia virus type-1 (HTLV-1) is an oncogenic retrovirus that causes multiple disorders, including adult T-cell leukemia and HTLV-1-associated myelopathy/tropical spastic paraparesis. HTLV-1 retroviral integrase binds to the regulatory B’56γ subunit of the host cell Protein Phosphatase 2A (PP2A). Integrase contains a highly conserved LxxIxE motif that is essential for binding, which increases integration efficiency and facilitates HTLV-1 hijack of host cell machinery. We aim to understand how mutations introduced in the highly conserved binding site can affect viral particle production and infectivity. We transfected 729B human lymphoblastoid cells and 293T cells with mutant and wildtype virus. Mutations L213A, …
Investigating Localization And Activity-Dependent Translation Of Astrocyte Mrna, Rohan Khazanchi
Investigating Localization And Activity-Dependent Translation Of Astrocyte Mrna, Rohan Khazanchi
Senior Honors Papers / Undergraduate Theses
Over the past two and a half years, I have studied fundamental aspects of astrocyte biology by investigating the existence and mechanism of astrocyte local translation peripherally around tripartite synapses consisting of pre- and post-synaptic neuron terminals and an associated astrocyte. Astrocytes are critical components of central nervous system synapses (which are predominately tripartite in nature); thus, it is important to consider how astrocyte dysregulation and dysfunction could contribute to the pathogenesis of diseases of synaptic connectivity such as autism spectrum disorders, Alzheimer’s disease, seizure disorders, and more. Overall, my projects involved the development of novel methods to identify astrocyte-specific …

Phylogenetically Novel Species Are More Successful Due To High Competitive Ability At Local And Regional Scales, Amy C. Patterson
Senior Honors Papers / Undergraduate Theses
While few introduced exotic species become invasive, this small number of species poses serious threats to biodiversity, ecosystem function, and recreation, leading ecologists to study why certain species become invasive and why certain communities are prone to invasions. Several leading hypotheses seek to explain invasiveness, including the Enemy Release Hypothesis, the trait superiority hypothesis, and the Biotic Resistance Hypothesis, but none are consistently supported in the literature. We suggest that the lack of uniting hypothesis is a result of the inability to put multiple proposed mechanisms in the same framework, and suggest for a uniting framework Darwin’s Naturalization Hypothesis along …
