A Pathway To Solving The Structure Of Cl-Par-4 Tumor Suppressor Protein: Challenges & Findings, Krishna Raut, Samjhana Pandey, Andrea M. Clark, Komala Ponniah, Steven M. Pascal

College of Sciences Posters

Prostate apoptosis response-4 (Par-4) is a pro-apoptotic tumor suppressor protein. Down-regulation of this protein has been reported in a myriad of cancers. Conversely, up-regulation of Par-4 is found to be associated with several neurodegenerative disorders. Par-4 is unique in the sense it can selectively induce apoptosis in cancer cells. For this, caspase-dependent intracellular cleavage of Par-4 is essential to produce the functionally active fragment, cl-Par-4 (caspase-cleaved Par-4). The cl-Par-4 protein inhibits the NF-κB-mediated cell survival pathway and causes selective apoptosis in various tumor cells.

Our laboratory is interested in determining the structure of cl-Par-4 and understanding it’s interaction with various …

Potential Regulation Of Breast Cancer Invasion By Thymidine Kinase 1, Eliza E. Bitter, Rachel M. Morris, Toni O. Mortimer, Kai Barlow, Abigail Schekall, Michelle H. Townsend, Jonathan Skidmore, Brett E. Pickett, Kim L. O'Neill

Library/Life Sciences Undergraduate Poster Competition 2022

Breast cancer is the most common cancer in women and is largely treatable within the early stages of the disease. However, patient mortality drastically declines as the tumor begins to invade other tissues and metastasize, making aggressive phenotypes especially problematic to treat. Such treatment typically requires an aggressive and decisive multidisciplinary approach. The recent expansion of immunotherapy as a viable treatment option has greatly improved treatment outcomes, especially with aggressive breast cancer phenotypes. Thymidine kinase 1 (TK1) is a DNA salvage pathway enzyme that is highly expressed during S phase and involved in cell cycle repair. Past studies indicated that …

The Role Of Cd5 In Cd4+ T Cell Metabolism, Joshua Bennett, Kiara Whitley, Claudia Freitas Phd, Christopher Haynie, Carlos Moreno, Scott Weber

Library/Life Sciences Undergraduate Poster Competition 2022

T cells serve a key role in the immunological response in the adaptive system. Different receptors present on the T cell have certain roles and are able to either inhibit or stimulate signaling which consequently regulates the function and metabolism of the cell. CD5 is an inhibitory co receptor expressed on the surface of T cells known to regulate thymocyte selection and TCR signaling . Our goal is to better understand the effects of CD5 regulation in metabolism. Using metabolic flux assays, we found that CD5KO naïve T cells have increased glycolysis and mitochondrial respiration in comparison to wild type …

Simulation Of An Inflammatory Model Using Schwann Cells, Caitlyn E. Henry, Peyton Kimmel, Mackenzie Wilcox, Angela Asirvatham

SURF Posters 2022

Schwann cells are a type of glial cell in the peripheral nervous system that produce the myelin sheath surrounding neuronal axons. This myelin insulates the neurons and promotes the rapid conduction of electrical impulses throughout the body. Schwann cells have also been found to play a critical role in neuron repair following nerve injury. During nerve injury, the myelin sheath is damaged, stimulating Schwann cells to release cytokines, or inflammatory mediators, that recruit immune cells to the site of injury so that the myelin debris can be cleared, and repair can take place.1 Then neuronal growth is facilitated by heregulin …
