Pharmacy Practice and Science Faculty Publications

Purpose: Malignant hyperthermia (MH) is a critical and potentially life-threatening emergency associated with inhaled anesthetic and depolarizing neuromuscular blocker administration. This is a single center’s response to MH. Summary: When signs of MH are observed, a page for “anesthesia STAT-MH crisis” is called, triggering a multidisciplinary response, including the deployment of a Malignant Hyperthermia Cart. The MH cart and the delegation of duties allows nurses, physicians and pharmacists to quickly understand their role in the stabilization, transition and recovery of a suspected MH patient. Conclusion: This case highlights the importance of multi-disciplinary involvement in these rare, but potentially fatal, cases.

Acute And Chronic Dosing Of A High-Affinity Rat/Mouse Chimeric Transferrin Receptor Antibody In Mice, Demi M. Castellanos, Jiahong Sun, Joshua Yang, Weijun Ou, Alexander C. Zambon, William M. Pardridge, Rachita K. Sumbria

Pharmacy Faculty Articles and Research

Non-invasive brain delivery of neurotherapeutics is challenging due to the blood-brain barrier. The revived interest in transferrin receptor antibodies (TfRMAbs) as brain drug-delivery vectors has revealed the effect of dosing regimen, valency, and affinity on brain uptake, TfR expression, and Fc-effector function side effects. These studies have primarily used monovalent TfRMAbs with a human constant region following acute intravenous dosing in mice. The effects of a high-affinity bivalent TfRMAb with a murine constant region, without a fusion partner, following extravascular dosing in mice are, however, not well characterized. Here we elucidate the plasma pharmacokinetics and safety of a high-affinity bivalent …

Lyubchenko, Deniz Kirik, Jean-Christophe Rochet

Journal Articles: Pharmaceutical Sciences

BACKGROUND: α-Synuclein (aSyn) aggregation is thought to play a central role in neurodegenerative disorders termed synucleinopathies, including Parkinson's disease (PD). Mouse aSyn contains a threonine residue at position 53 that mimics the human familial PD substitution A53T, yet in contrast to A53T patients, mice show no evidence of aSyn neuropathology even after aging. Here, we studied the neurotoxicity of human A53T, mouse aSyn, and various human-mouse chimeras in cellular and in vivo models, as well as their biochemical properties relevant to aSyn pathobiology.

METHODS: Primary midbrain cultures transduced with aSyn-encoding adenoviruses were analyzed immunocytochemically to determine relative dopaminergic neuron viability. …

Click-Free Synthesis Of A Multivalent Tricyclic Peptide As A Molecular Transporter, Sumit Kumar, Dindyal Mandal, Shaima Ahmed El-Mowafi, Saghar Mozaffari, Rakesh Kumar Tiwari, Keykavous Parang

Pharmacy Faculty Articles and Research

The cellular delivery of cell-impermeable and water-insoluble molecules remains an ongoing challenge to overcome. Previously, we reported amphipathic cyclic peptides c[WR]₄ and c[WR]₅ consisting of alternate arginine and tryptophan residues as nuclear-targeting molecular transporters. These peptides contain an optimal balance of positive charge and hydrophobicity, which is required for interactions with the phospholipid bilayer to facilitate their application as a drug delivery system. To further optimize them, we synthesized and evaluated a multivalent tricyclic peptide as an efficient molecular transporter. The monomeric cyclic peptide building blocks were synthesized using Fmoc/tBu solid-phase chemistry and cyclization in the …

Lipocalin-2 Deficiency May Predispose To The Progression Of Spontaneous Age-Related Adiposity In Mice, Keya Meyers, María López, Joanna Ho, Savannah Wills, Srujana Rayalam, Shashidharamurthy Taval

PCOM Scholarly Works

Lipocalin-2 (Lcn2) is an innate immune protein elevated by several orders of magnitude in various inflammatory conditions including aging and obesity. Recent studies have shown that Lcn2 is secreted by adipocytes in response to inflammation and is categorized as a new adipokine cross-linking innate immunity and metabolic disorders including obesity. However, the involvement of Lcn2 and its function during the progression of obesity is largely unknown. Recently, browning of white adipose tissue (WAT) has gained attention as a therapeutic strategy to combat obesity. Herein, we have shown that treatment of mature 3T3-L1 adipocytes with recombinant Lcn2 (rec-Lcn2) resulted in the …

Aluminum Reproductive Toxicity: A Summary And Interpretation Of Scientific Reports, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Publications addressing aluminum (Al)-induced reproductive toxicity were reviewed. Key details were compiled in summary tables. Approximate systemic Al exposure, a measure of bioavailability, was calculated for each exposure, based on the Al percentage in the dosed Al species, Al bioavailability, and absorption time course reports for the exposure route. This was limited to laboratory animal studies because no controlled-exposure human studies were found. Intended Al exposure was compared to unintended dietary Al exposure. The considerable and variable Al content of laboratory animal diets creates uncertainty about reproductive function in the absence of Al. Aluminum-induced reproductive toxicity in female mice and …

Hydrophobic Interactions Between The Ha Helix And S4‐S5 Linker Modulate Apparent Ca2+ Sensitivity Of Sk2 Channels, Young-Woo Nam, Meng Cui, Razan Orfali, Adam Viegas, Misa Nguyen, Eman H. M. Mohammed, Khalid Zoghebi, Simin Rahighi, Keykavous Parang, Miao Zhang

Pharmacy Faculty Articles and Research

Aim

Small‐conductance Ca²⁺‐activated potassium (SK) channels are activated exclusively by increases in intracellular Ca²⁺, that binds to calmodulin constitutively associated with the channel. Wild‐type SK2 channels are activated by Ca²⁺ with an EC50 value of ~0.3 μM. Here, we investigate hydrophobic interactions between the HA helix and the S4‐S5 linker as a major determinant of channel apparent Ca²⁺ sensitivity.

Methods

site‐directed mutagenesis, electrophysiological recordings and molecular dynamic (MD) simulations were utilized.

Results

Mutations that decrease hydrophobicity at the HA‐S4‐S5 interface lead to Ca²⁺ hyposensitivity of SK2 channels. Mutations that increase hydrophobicity result in …

Sanders-Brown Center on Aging Faculty Publications

TAR DNA-binding protein 43 (TDP-43) is a nuclear RNA/DNA binding protein involved in mRNA metabolism. Aberrant mislocalization to the cytoplasm and formation of phosphorylated/aggregated TDP-43 inclusions remains the hallmark pathology in a spectrum of neurodegenerative diseases, including frontotemporal disorders and Alzheimer's disease. Eukaryotic Translation Initiation Factor 5A undergoes a unique post-translation modification of lysine to hypusine (K50), which determines eIF5A binding partners. We used a sodium arsenite-induced cellular stress model to investigate the role of hypusinated eIF5A (eIF5A^HypK50) in governing TDP-43 cytoplasmic mislocalization and accumulation in stress granule. Our proteomics and functional data provide evidence that eIF5A interacts …
