Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines
2026 Symposium
Two of the major nucleotide bases in DNA and RNA (Adenine and Guanine) are derived from the purine Inosine Monophosphate (IMP). IMP may occasionally form the noncanonical nucleotide Inosine Triphosphate (ITP) within the cell and become incorporated into DNA during replication, leading to potentially lethal errors. To combat this, human cells produce the “housekeeping” enzyme Inosine Triphosphatase (ITPA) to revert ITP to IMP. A mutation of this protein that replaces the 178th amino acid Arginine with Cysteine (R178C) is associated with a fatal infantile encephalopathy. Previous assessments of enzyme-substrate binding and catalysis for ITPA variants have been run at a …

Background: Hox genes encode transcriptional factors that regulate the expression of specific target genes along the anterior-posterior axis determining the segment identity during embryonic development. These master genes are expressed in the same order in which are located in the third chromosome of Drosophila melanogaster. As it was previously reported the interaction of neighboring Hox proteins as Scr-Antp and Antp-Ubx and one of the mechanisms for Hox protein regulation is protein-protein interaction, we determined the heterodimer formation of Ubx with AbdA and AbdB as well as the homodimer formation of these proteins in living cells which in turn could …

Candida albicans is an opportunistic human pathogenic fungus affecting millions of people globally; high mortality rates are possible in systemic infection. Filamentation or a filamentous growth pattern is a primary virulence mechanism of C. albicans underlying other virulent behaviour....

Summer Research
Th17 cells are found to be heavily depleted in the gut of HIV patients. Even after successful antiretroviral therapy, HIV patients exhibit a smaller Th17 population for years after treatment. Previous research has found human intestinal endothelial cells (IEC) to increase HIV infection of helper T cells. Using CCR6 as a marker for Th17, we investigated the effect of IEC on HIV infection of Th17 cells. IECs were found to increase the preferential infection of resting and activated CCR6+ cells. Th17 cells are known to be more susceptible to HIV infection than other types of CD4+ T cells. IEC stimulation …

Summer Research
A major barrier to eradicating HIV is latent reservoirs in resting CD4+ T cells. Antiretroviral therapy is effective in bringing the viral load down to undetectable levels but is unable to eradicate the latent reservoir. Previous data from our lab revealed that when stimulated by intestinal endothelial cells (IEC), resting CD4+ T cells can be directly infected while remaining in a resting state, allowing formation of latent reservoirs. An additional study found that integrins, which are cell surface molecules, play a role in the interactions between endothelial cells (EC) and T cells. Our research further examines the role of integrins …

Post-translational modifications regulate the activities of proteins important to numerous diseases. Spleen Tyrosine Kinase (Syk) is particularly interesting to researchers because it modifies many targets and plays multiple roles in regulating cells in our bodies and its abnormal modifications may contribute to cancer, Alzheimer’s disease and allergies. In an attempt to study these modifications of Syk, we first looked at detecting ubiquitination on Syk protein. Ubiquitin, a small 8 kDa molecule, attaches to lysine residues on protein. The attachment of ubiquitin to Syk may cause Syk to either propagate signals onwards to activate other proteins or signal it to undergo …
