Degradation Of Vitamin E Acetate Through Vaping Produces Byproducts Cytotoxic To Thp-1 Monocytic Cells, Joshua Alcon

Pharmaceutical Sciences ETDs

Electronic cigarette or vaping use associated lung injury (EVALI) is a pulmonary disease among those who vaped illicit tetrahydrocannabinol (THC) cartridges that resulted in hospitalization or death. Vitamin E acetate (VEA) was a common additive present in the bronchioalveolar lavage fluid (BALF) of patients who were hospitalized with EVALI. However, little is known about pulmonary exposure to vitamin E acetate (VEA) when inhaled through vaping. The hypothesis of this study is the cytotoxicity of vaped VEA is due, at least in part, to the pyrolytic breakdown products of VEA produced by vaping, as opposed to VEA itself. From this study, …

Pharmacy Faculty Articles and Research

Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome leads to diarthrodial joint arthropathy and is caused by the absence of lubricin (proteoglycan 4—PRG4), a surface-active mucinous glycoprotein responsible for lubricating articular cartilage. In this study, mice lacking the orthologous gene Prg4 served as a model that recapitulates the destructive arthrosis that involves biofouling of cartilage by serum proteins in lieu of Prg4. This study hypothesized that Prg4-deficient mice would demonstrate a quadruped gait change and decreased markers of mitochondrial dyscrasia, following intra-articular injection of both hindlimbs with recombinant human PRG4 (rhPRG4). Prg4^−/− (N = 44) mice of both sexes were injected with rhPRG4 …

Potential Pro-Inflammatory Effect Of Vitamin E Analogs Through Mitigation Of Tetrahydrocannabinol (Thc) Binding To The Cannabinoid 2 Receptor, Anjela Manandhar, Mona H. Haron, Samir A. Ross, Michael L. Klein

Faculty and Student Publications

Vitamin E acetate, which is used as a diluent of tetrahydrocannabinol (THC), has been reported as the primary causative agent of e-cigarette, or vaping, product use-associated lung injury (EVALI). Here, we employ in vitro assays, docking, and molecular dynamics (MD) computer simulations to investigate the interaction of vitamin E with the membrane-bound cannabinoid 2 receptor (CB2R), and its role in modulating the binding affinity of THC to CB2R. From the MD simulations, we determined that vitamin E interacts with both CB2R and membrane phospholipids. Notably, the synchronized effect of these interactions likely facilitates vitamin E acting as a lipid modulator …
