Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Acute interstitial pneumonia (AIP), also known as Hamman-Rich syndrome, is a rapidly progressive interstitial lung disease. In addition to being challenging to diagnose, AIP is also difficult to treat. The mortality rate of AIP is greater than 70% due to the disease's rapid progression. Furthermore, survivors are likely to develop chronic interstitial lung disease as a sequela. Treatment primarily focuses on supportive care, which consists of oxygenation through mechanical ventilation, administration of broad-spectrum antibiotics, and the use of corticosteroids. Although the use of steroids as empiric treatment is controversial and results on its mortality benefit are variable, some studies …

Investigation Of The Effects Of The Peptidylarginine Deiminase Inhibitor Cl-Amidine On Apoptosis And Gene Expression In Ovarian Cancer, Victoria Walden

Longwood Senior Thesis Proposal

Peptidylarginine deiminases (PADs) are a family of enzymatic proteins responsible for the conversion of arginine and methylarginine residues to citrulline. This conversion is important for several key cellular processes including transcriptional gene regulation. Recently, a link has been established between overexpression of a particular PAD, PAD4, and the accelerated progression of both autoimmune diseases and cancers. Ovarian cancer exhibits heightened levels of PAD4 in affected cells. High levels of PAD4 are associated with the formation of neutrophil extracellular traps (NETs) that promote cancer metastasis, and downregulation of the p53 apoptotic pathway. Thus, it is important to explore inhibitors of PAD4. …

Proposed Evaluation Of Nonpharmacological Treatments And Therapies For Paclitaxel Based Chemotherapy-Induced Peripheral Neuropathy (Cipn), Mackenzie Lesczcynski

D.U.Quark

Chemotherapy-induced Peripheral Neuropathy (CIPN) is a common complication in breast cancer patients receiving Paclitaxel, a chemotherapeutic agent (1). CIPN symptoms range from numbness to extreme pain and sensitivity in bodily extremities, forcing chemotherapy to be halted (2). The mechanism of this side effect is not well understood and there is no standard pharmacological treatment available to improve effects. Nonpharmacological treatments have been attempted on small patient cohorts, but there are no conclusive findings (3). Due to this, we believe that a comprehensive murine model must be developed in order to assess nonpharmacological treatment efficacy and potential molecular targets for pharmacological …

Penghambat Kanal Kalsium Sebagai Kontrol Glukosa Darah Pada Insulinoma: Sebuah Laporan Kasus, Nadhira Nizam, Ryan Tresna Putra, Anshari Saifuddin Hasibuan

Jurnal Penyakit Dalam Indonesia

Insulinoma is a rare neuroendocrine tumor of the pancreas arising from β-cells, leading to excessive insulin secretion and resultant hypoglycaemia. Surgical resection is the first-line treatment for insulinoma, but when surgery is not feasible, medical therapy is an important option. Calcium channel blockers (CCBs) such as verapamil can inhibit insulin release from β-cells and have been proposed as an adjunct therapy to help control blood glucose levels in insulinoma. We report a 43-year-old man who presented to the emergency department with decreased consciousness due to hypoglycaemia. His capillary blood glucose at home was 35 mg/dL, about 8 hours after his …

The glycocalyx is a dynamic carbohydrate-enriched structure that forms a dense coating on the surface of animal cells, including those at the ocular surface. It plays a critical role in maintaining cellular functions and it has a significant influence in disease processes. At the ocular surface, glycoproteins such as mucins are essential for hydration, lubrication, and barrier protection. Proteoglycans and glycolipids contribute to cell signaling, and mediate interactions with pathogens. Alterations in the glycocalyx are implicated in a spectrum of ocular conditions, including dry eye disease, ocular allergies, infections, and systemic diseases such as Graft-versus-host disease (GVHD) and diabetes mellitus. …

Domain Communication In Bifunctional Proline Utilization A From Sinorhizobium Meliloti, Emma Bitterman

Honors Program: Senior Projects (Public)

The reduction potential of flavin bound to Sinorhizobium meliloti proline utilization A (SmPutA) is beneficial in providing vital information on enzyme activity and the active site environment. Flavin is crucial in biological metabolism such as aerobic respiration and other important processes like oxygen activation that are catalyzed by flavin-dependent enzymes. (4). In this study, we seek to determine whether the redox potential of SmPutA-bound flavin can be used to characterize potential long-distance communication and analyze the possibilities of inactivation reversibility. SmPutA is a large bifunctional enzyme that catalyzes the overall oxidation of proline to glutamate via two catalytic domains (1). …

Radial Glia Integrin Avb8 Regulates Cell Autonomous Microglial Tgfβ1 Signaling That Is Necessary For Microglial Identity, Gabriel Mckinsey, Nicolas Santander, Xiaoming Zhang, Kilian Kleemann, Lauren Tran, Aditya Katewa, Kaylynn Conant, Matthew Barraza, Kian Waddell, Carlos Lizama, Marie La Russa, Ji Hyun Koo, Hyunji Lee, Dibyanti Mukherjee, Helena Paidassi, E. S. Anton, Kamran Atabai, Dean Sheppard, Oleg Butovsky, Thomas Arnold

Department of Medicine Faculty Papers

Microglial diversity arises from the interplay between inherent genetic programs and external environmental signals. However, the mechanisms by which these processes develop and interact within the growing brain are not yet fully understood. Here, we show that radial glia-expressed integrin beta 8 (ITGB8) activates microglia-expressed TGFβ1 to drive microglial development. Domain-restricted deletion of Itgb8 in these progenitors results in regionally restricted and developmentally arrested microglia that persist into adulthood. In the absence of autocrine TGFβ1 signaling, microglia adopt a similar phenotype, leading to neuromotor symptoms almost identical to Itgb8 mutant mice. In contrast, microglia lacking the canonical TGFβ signal transducers …

The Guanine Nucleotide Exchange Factor Ric-8a Regulates The Sensitivity Of Constitutively Active Gαq To The Inhibitor Ym-254890, Morgan Dwyer, Jiansong Luo, Tyson Todd, Kendall Blumer, Gregory Tall, Philip Wedegaertner

Department of Biochemistry and Molecular Biology Faculty Papers

Heterotrimeric G proteins are stimulated under normal circumstances by G protein-coupled receptors to promote downstream intracellular signaling. Mutations can occur in αq at glutamine 209 (Q209) that cause constitutive, G protein-coupled receptor independent signaling due to disruption of GTPase activity. Specifically, Q209L/P mutations are oncogenic drivers of uveal melanoma. YM-254890 (YM) has been shown to selectively inhibit both WT and constitutively active (CA) αqQ209L/P by preventing the release of GDP and exchange for GTP, thereby halting downstream signaling. Because αqQL/P are thought to be primarily GTP-bound and GTPase deficient, the current mechanistic understanding of YM inhibition needs further investigation to …

College of Health Professions Faculty Papers

The continued emergence of antimalarial drug resistance highlights the need to develop new antimalarial therapies. Unfortunately, new drug development is often hampered by undesirable drug-like properties of lead compounds. Prodrug approaches temporarily mask undesirable compound features, improving bioavailability and target penetration. We have found that lipophilic diester prodrugs of phosphonic acid antibiotics, such as fosmidomycin (Fsm), exhibit significantly higher antimalarial potency than their parent compounds [R.L. Edwards et al., Sci. Rep. 7, 8400 (2017)]. However, the activating enzymes for these prodrugs were unknown. Here, we show that an erythrocyte enzyme, acylpeptide hydrolase (APEH), is the major activating enzyme of multiple …

Hoek, Erik S. Knudsen, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Differences between normal tissues and invading tumors that allow tumor targeting while saving normal tissue are much sought after. Here we show that scarcity of VDAC2, and the consequent lack of Bak recruitment to mitochondria, renders hepatocyte mitochondria resistant to permeabilization by truncated Bid (tBid), a Bcl-2 Homology 3 (BH3)-only, Bcl-2 family protein. Increased VDAC2 and Bak is found in most human liver cancers and mitochondria from tumors and hepatic cancer cell lines exhibit VDAC2- and Bak-dependent tBid sensitivity. Exploring potential therapeutic targeting, we find that combinations of activators of the tBid pathway with inhibitors of the Bcl-2 family proteins …

Gatad2b O-Glcnacylation Regulates Breast Cancer Stem-Like Potential And Drug Resistance, Giang Le Minh, Jessica Merzy, Emily Esquea, Nusaiba Ahmed, Riley Young, Ryan Sharp, Tejsi Dhameliya, Bernice Agana, Mi-Hye Lee, Jennifer Bethard, Susana Comte-Walters, Lauren Ball, Mauricio Reginato

Kimmel Cancer Center Faculty Papers

The growth of breast tumors is driven and controlled by a subpopulation of cancer cells resembling adult stem cells, which are called cancer stem-like cells (CSCs). In breast cancer, the function and maintenance of CSCs are influenced by protein O-GlcNAcylation and the enzyme responsible for this post-translational modification, O-GlcNAc transferase (OGT). However, the mechanism of CSCs regulation by OGT and O-GlcNAc cycling in breast cancer is still unclear. Analysis of the proteome and O-GlcNAcome, revealed GATAD2B, a component of the Nucleosome Remodeling and Deacetylase (NuRD) complex, as a substrate regulated by OGT. Reducing GATAD2B genetically impairs mammosphere formation, decreases expression …
