Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines
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 …

Bone remodeling is a dynamic process that requires a balance between bone resorption by osteoclasts and bone formation by osteoblasts to maintain skeletal integrity. Disruptions to this equilibrium can lead to pathological conditions such as osteoporosis. Osteoclasts originate from macrophages, and their differentiation is regulated by several signaling pathways, notably the notch signaling pathway. Gamma-secretase, an enzyme crucial for initiating notch signaling, can be inhibited by DAPT. However, DAPT also targets non-Notch substrates, complicating the identification of genes specifically regulated by Notch. To address this limitation, this study employed IMR-1A, a selective Notch pathway inhibitor that disrupts the assembly of …

Acne vulgaris is one of the most common skin diseases globally. One key aspect of acne pathogenesis is the disturbance of healthy strain diversity of the skin bacterium Cutibacterium acnes. Many acne treatments are antimicrobial; however, these treatments are generally nonspecific and carry a variety of side effects in addition to contributing to rising antibiotic resistance. Lytic bacteriophages (or phages) are viruses that infect and kill bacteria. Their lytic lifestyle is facilitated by enzymes called endolysins. Phages have been studied as an alternative to traditional antimicrobials in acne treatment and have shown reduced C. acnes load in acne lesions and …

Acne vulgaris (acne) is the eighth most common skin disorder worldwide. Because of the heterogeneous pathology of acne and the increasing antibiotic resistance of the causal agent (Cutibacterium acnes), novel therapeutics need to be developed to treat acne. One option is endolysins, highly conserved enzymes from bacteriophages that disrupt the bacterial cell wall. Endolysins retain bactericidal and bacteriostatic activity when applied to bacteria in vitro and are safe for topical application. We hypothesize that the endolysin (ENDL) from the P100.1 C. acnes bacteriophage will exhibit bacteriostatic activity against C. acnes in vitro. This study aims to bioinformatically characterize the P100.1 …

Chronic inflammation stems from the inability of the body to resolve acute inflammation. Chronic inflammation is a growing health concern, as nearly 60% of Americans reported coping with at least one chronic condition (as of 2014). On a world scale, three fifths of deaths result from a chronic inflammation disease. Treatments for chronic inflammation include lifestyle changes (diet and exercise) and a variety of conventional drugs. Beyond these treatments, supplementing the body with systemic enzymes may attenuate inflammation. One promising enzyme is serratiopeptidase. Serratiopeptidase is a serine protease expressed by Serratia marcescens which has demonstrated anti-inflammatory, anti-edemic, and analgesic activity …
