Evaluating The Effect Of Skipping Ticagrelor Doses And Need For Bolus Doses Upon Treatment Resumption Through Population Pk/Pd Simulation, Hiroyoshi Matsui, Le Thien Truc Pham, Eyob D. Adane

ONU Student Research Colloquium

Ticagrelor (Brilinta (R)) is the first reversibly binding oral P2Y12 receptor antagonist. It is used, mostly in combination with aspirin, in patients with acute coronary syndromes to reduce thrombosis. The manufacturer of ticagrelor recommends discontinuing it at least 5 days before any surgery when possible. While the effect of dose interruptions on the risk of thrombosis is not directly studied, it is important to understand the impact of skipping doses on ticagrelor's PK/PD profile for clinical-decision making. The objectives of the current study were to simulate the impact of therapy interruption on the PK/PD of ticagrelor and examine the need …

Characterization Of Epithelial Growth Factor Transcripts Identified In Crotalus Atrox Venom, Ivan Lopez, Ying Jia

Research Symposium

Epithelial Growth Factor (EGF) is the primary source in regeneration and stimulation of essential fibroblasts cells commonly found in epithelium. Studies have shown that snake venom components are becoming a growing factor in treating illnesses such as cancer, muscular dystrophy, chronic pain, blood pressure, blood clotting, etc. EGF in human cells contains a promising quaternary structure that can bind to snake venom metalloproteinases, proposing a means of activating biochemical responses through protein-protein interactions to regulate unwanted cellular functions. This supports promising research in achieving a greater understanding of regulation along cellular pathways through ligands, increasing the likelihood of targeting unwanted …

Identifying The Enzyme Involved In Vacuolar Atpase Acetylation During Doxorubicin-Induced Cardiotoxicity, Rebecca Dang, Tianqing Peng

Western Research Forum

Doxorubicin is an established anticancer medication infamous for its bright colouration and extremely toxic side effects. Emerging studies support that the imbalance between acetylation and deacetylation disrupts the autophagic flux leading to doxorubicin-induced cardiotoxicity. Vacuolar ATPases are a family of electrogenic proton pumps present on the lysosomal membrane that create an acidic environment for proteases to degrade proteins. Our preliminary study found that acetylated Vacuolar ATPase subunit V₀ D1 levels increased in doxorubicin-injected mouse hearts. However, it is unknown how acetylation of subunit V₀ D1 is modulated and whether this modification plays a role in doxorubicin-induced cardiotoxicity.
