Inferior Stemi Complicated By Retroperitoneal Hemorrhage Due To Ruptured Aaa, Farley B. Neasman Iii, Melissa D. Lester, Nepal C. Chowdhury

Marshall Journal of Medicine

When patients present with life threatening conditions, a rapid cost-benefit analysis prioritizes care and commits treatment to a certain course that, in the case of ST Elevation Myocardial Infarction (STEMI) treated with drug-eluting stents (DES), could be fatal if there is any deviation. Antiplatelet therapy is vital and secondary concerns (i.e. bleeding diatheses) may accept suboptimal outcomes – in rare cases, another life-threatening condition may be unmasked, the treatment for which runs directly counter to the first. We present a case of STEMI with high clot burden treated with multiple DES, complicated by retroperitoneal hemorrhage due to a ruptured abdominal …

Ladarixin, A Dual Cxcr1/2 Inhibitor, Attenuates Experimental Melanomas Harboring Different Molecular Defects By Affecting Malignant Cells And Tumor Microenvironment., Daria Marley Kemp, Alyson Pidich, Mary Larijani, Rebecca Jonas, Elizabeth Lash, Takami Sato, Mizue Terai, Maria De Pizzol, Marcello Allegretti, Olga Igoucheva, Vitali Alexeev

Department of Dermatology and Cutaneous Biology Faculty Papers

CXCR1 and CXCR2 chemokine receptors and their ligands (CXCL1/2/3/7/8) play an important role in tumor progression. Tested to date CXCR1/2 antagonists and chemokine-targeted antibodies were reported to affect malignant cells in vitro and in animal models. Yet, redundancy of chemotactic signals and toxicity hinder further clinical development of these approaches. In this pre-clinical study we investigated the capacity of a novel small molecule dual CXCR1/2 inhibitor, Ladarixin (LDX), to attenuate progression of experimental human melanomas. Our data showed that LDX-mediated inhibition of CXCR1/2 abrogated motility and induced apoptosis in cultured cutaneous and uveal melanoma cells and xenografts independently of the …

Fsd-C10, A Fasudil Derivative, Promotes Neuroregeneration Through Indirect And Direct Mechanisms., Yan-Hua Li, Chong Xie, Yuan Zhang, Xing Li, Hai-Fei Zhang, Qing Wang, Zhi Chai, Bao-Guo Xiao, Rodolfo Thome, Guang-Xian Zhang, Cun-Gen Ma

Department of Neurology Faculty Papers

FSD-C10, a Fasudil derivative, was shown to reduce severity of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS), through the modulation of the immune response and induction of neuroprotective molecules in the central nervous system (CNS). However, whether FSD-C10 can promote neuroregeneration remains unknown. In this study, we further analyzed the effect of FSD-C10 on neuroprotection and remyelination. FSD-C10-treated mice showed a longer, thicker and more intense MAP2 and synaptophysin positive signal in the CNS, with significantly fewer CD4(+) T cells, macrophages and microglia. Importantly, the CNS of FSD-C10-treated mice showed a shift of activated macrophages/microglia from …

Phlpp Regulates Hexokinase 2-Dependent Glucose Metabolism In Colon Cancer Cells, Xiaopeng Xiong, Yang-An Wen, Mihail I. Mitov, Mary C. Oaks, Shigeki Miyamoto, Tianyan Gao

Markey Cancer Center Faculty Publications

Increased glucose metabolism is considered as one of the most important metabolic alterations adapted by cancer cells in order to generate energy as well as high levels of glycolytic intermediates to support rapid proliferation. PH domain leucine-rich repeat protein phosphatase (PHLPP) belongs to a novel family of Ser/Thr protein phosphatases that function as tumor suppressors in various types of human cancer. Here we determined the role of PHLPP in regulating glucose metabolism in colon cancer cells. Knockdown of PHLPP increased the rate of glucose consumption and lactate production, whereas overexpression of PHLPP had the opposite effect. Bioenergetic analysis using Seahorse …

High Throughput In Vivo Functional Validation Of Candidate Congenital Heart Disease Genes In Drosophila., Jun-Yi Zhu, Yulong Fu, Margaret Nettleton, Adam Richman, Zhe Han

Pediatrics Faculty Publications

Genomic sequencing has implicated large numbers of genes and de novo mutations as potential disease risk factors. A high throughput in vivo model system is needed to validate gene associations with pathology. We developed a Drosophila-based functional system to screen candidate disease genes identified from Congenital Heart Disease (CHD) patients. 134 genes were tested in the Drosophila heart using RNAi-based gene silencing. Quantitative analyses of multiple cardiac phenotypes demonstrated essential structural, functional, and developmental roles for more than 70 genes, including a subgroup encoding histone H3K4 modifying proteins. We also demonstrated the use of Drosophila to evaluate cardiac phenotypes resulting …

Identification, Validation, And Targeting Of The Mutant P53- Parp-Mcm Chromatin Axis In Triple Negative Breast Cancer, Wei-Gang Qiu, Alla Polotskaia, Gu Xiao, Lia Di, Yuhan Zhao, Wenwei Hu, John Philip, Ronald C. Hendrickson, Jill Bargonetti

Publications and Research

Over 80% of triple negative breast cancers express mutant p53. Mutant p53 often gains oncogenic function suggesting that triple negative breast cancers may be driven by p53 protein type. To determine the chromatin targets of this gain-of-function mutant p53 we used inducible knockdown of endogenous gain-of-function mtp53 in MDA-MB-468 cells in conjunction with stable isotope labeling with amino acids in cell culture and subcellular fractionation. We sequenced over 70,000 total peptides for each corresponding reciprocal data set and were able to identify 3010 unique cytoplasmic fraction proteins and 3403 unique chromatin fraction proteins. The present proteomics experiment corroborated our previous …

Crispr-Cas9 Mediated Nox4 Knockout Inhibits Cell Proliferation And Invasion In Hela Cells, Naser Jafari, Hyunju Kim, Rackhyun Park, Liqing Li, Minsu Jang, Andrew J. Morris, Junsoo Park, Cai Huang

Markey Cancer Center Faculty Publications

Increased expression of NOX4 protein is associated with cancer progression and metastasis but the role of NOX4 in cell proliferation and invasion is not fully understood. We generated NOX4 knockout HeLa cell lines using the CRISPR-Cas9 gene editing system to explore the cellular functions of NOX4. After transfection of CRISPR-Cas9 construct, we performed T7 endonuclease 1 assays and DNA sequencing to generate and identify insertion and deletion of the NOX4 locus. We confirmed the knockout of NOX4 by Western blotting. NOX4 knockout cell lines showed reduced cell proliferation with an increase of sub-G1 cell population and the decrease of S/G2/M …

Impact Of Tigecycline Versus Other Antibiotics On The Fecal Metabolome And On Colonization Resistance To Clostridium Difficile In Mice, Robin L.P. Jump, David Kraft, Kelly Hurless, Alex Polinkovsky, Curtis J. Donskey

Faculty Scholarship

Background: The glycylcycline antibiotic tigecycline may have a relatively low propensity to promote Clostridium difficile infection in part because it causes less disruption of the indigenous intestinal microbiota than other broad-spectrum antibiotics. We used a mouse model to compare the effects of tigecycline versus other commonly used antibiotics on colonization resistance to C. difficile and on the metabolic functions of the intestinal microbiota. Methods: To assess in vivo colonization resistance to C. difficile, mice were challenged with oral C. difficile spores 1, 7, or 12 days after completion of 3 days of treatment with subcutaneous saline, tigecycline, ceftriaxone, piperacillin-tazobactam, or …

Persistent Amygdala Novelty Response Is Associated With Less Anterior Cingulum Integrity In Trauma-Exposed Women, Seungyeon A. Yoon, Mariann R. Weierich

Neurology Faculty Publications

Accurate prediction of Alzheimer’s disease (AD) is important for the early diagnosis and treatment of this condition. Mild cognitive impairment (MCI) is an early stage of AD. Therefore, patients with MCI who are at high risk of fully developing AD should be identified to accurately predict AD. However, the relationship between brain images and AD is difficult to construct because of the complex characteristics of neuroimaging data. To address this problem, we present a longitudinal measurement of MCI brain images and a hierarchical classification method for AD prediction. Longitudinal images obtained from individuals with MCI were investigated to acquire important …

Omecamtiv Mecarbil Enhances The Duty Ratio Of Human Β-Cardiac Myosin Resulting In Increased Calcium Sensitivity And Slowed Force Development In Cardiac Muscle, Anja M. Swenson, Wanjian Tang, Cheavar A. Blair, Christopher M. Fetrow, William C. Unrath, Michael J. Previs, Kenneth S. Campbell, Christopher M. Yengo

Physiology Faculty Publications

The small molecule drug omecamtiv mecarbil (OM) specifically targets cardiac muscle myosin and is known to enhance cardiac muscle performance, yet its impact on human cardiac myosin motor function is unclear. We expressed and purified human β-cardiac myosin subfragment 1 (M2β-S1) containing a C-terminal Avi tag. We demonstrate that the maximum actin-activated ATPase activity of M2β-S1 is slowed more than 4-fold in the presence of OM, whereas the actin concentration required for half-maximal ATPase was reduced dramatically (30-fold). We find OM does not change the overall actin affinity. Transient kinetic experiments suggest that there are …

Hic1 (Hypermethylated In Cancer 1) Sumoylation Is Dispensable For Dna Repair But Is Essential For The Apoptotic Dna Damage Response (Ddr) To Irreparable Dna Double-Strand Breaks (Dsbs)., Sonia Paget, Marion Dubuissez, Vanessa Dehennaut, Joe Nassour, Brennan T Harmon, Nathalie Spruyt, Ingrid Loison, Corinne Abbadie, Brian R Rood, Dominique Leprince

Surgery Faculty Publications

The tumor suppressor gene HIC1 (Hypermethylated In Cancer 1) encodes a transcriptional repressor mediating the p53-dependent apoptotic response to irreparable DNA double-strand breaks (DSBs) through direct transcriptional repression of SIRT1. HIC1 is also essential for DSB repair as silencing of endogenous HIC1 in BJ-hTERT fibroblasts significantly delays DNA repair in functional Comet assays. HIC1 SUMOylation favours its interaction with MTA1, a component of NuRD complexes. In contrast with irreparable DSBs induced by 16-hours of etoposide treatment, we show that repairable DSBs induced by 1 h etoposide treatment do not increase HIC1 SUMOylation or its interaction with MTA1. Furthermore, HIC1 SUMOylation …

Novel Long-Chain Compounds With Both Immunomodulatory And Mena Inhibitory Activities Against Staphylococcus Aureus And Its Biofilm., Seoung-Ryoung Choi, Joel Frandsen, Prabagaran Narayanasamy

Journal Articles: Pathology and Microbiology

Menaquinone (MK) biosynthesis pathway is a potential target for evaluating antimicrobials in gram-positive bacteria. Here, 1,4-dihydroxy-2-naphthoate prenyltransferase (MenA) was targeted to reduce methicillin-resistant Staphylococcus aureus (MRSA) growth. MenA inhibiting, long chain-based compounds were designed, synthesized and evaluated against MRSA and menaquinone utilizing bacteria in aerobic conditions. The results showed that these bacteria were susceptible to most of the compounds. Menaquinone (MK-4) supplementation rescued MRSA growth, suggesting these compounds inhibit MK biosynthesis. 3a and 7c exhibited promising inhibitory activities with MICs ranging 1-8 μg/mL against MRSA strains. The compounds did not facilitate small colony variant formation. These compounds also inhibited the …

Radiation Medicine Faculty Publications

The induction of tumor suppressor proteins capable of cancer cell apoptosis represents an attractive option for the re-purposing of existing drugs. We report that the anti-malarial drug, chloroquine (CQ), is a robust inducer of Par-4 secretion from normal cells in mice and cancer patients in a clinical trial. CQ-inducible Par-4 secretion triggers paracrine apoptosis of cancer cells and also inhibits metastatic tumor growth. CQ induces Par-4 secretion via the classical secretory pathway that requires the activation of p53. Mechanistically, p53 directly induces Rab8b, a GTPase essential for vesicle transport of Par-4 to the plasma membrane prior to secretion. Our findings …

Androgen Receptor-Dependent And -Independent Mechanisms Driving Prostate Cancer Progression: Opportunities For Therapeutic Targeting From Multiple Angles., David T. Hoang, Kenneth A. Iczkowski, Deepak Kilari, William See, Marja T. Nevalainen

Student Papers, Posters & Projects

Despite aggressive treatment for localized cancer, prostate cancer (PC) remains a leading cause of cancer-related death for American men due to a subset of patients progressing to lethal and incurable metastatic castrate-resistant prostate cancer (CRPC). Organ-confined PC is treated by surgery or radiation with or without androgen deprivation therapy (ADT), while options for locally advanced and disseminated PC include radiation combined with ADT, or systemic treatments including chemotherapy. Progression to CRPC results from failure of ADT, which targets the androgen receptor (AR) signaling axis and inhibits AR-driven proliferation and survival pathways. The exact mechanisms underlying the transition from androgen-dependent PC …

Natural Compounds Targeting Major Cell Signaling Pathways: A Novel Paradigm For Osteosarcoma Therapy., Pablo Angulo, Gaurav Kaushik, Dharmalingam Subramaniam, Prasad Dandawate, Kathleen Neville, Katherine Chastain, Shrikant Anant

Manuscripts, Articles, Book Chapters and Other Papers

Osteosarcoma is the most common primary bone cancer affecting children and adolescents worldwide. Despite an incidence of three cases per million annually, it accounts for an inordinate amount of morbidity and mortality. While the use of chemotherapy (cisplatin, doxorubicin, and methotrexate) in the last century initially resulted in marginal improvement in survival over surgery alone, survival has not improved further in the past four decades. Patients with metastatic osteosarcoma have an especially poor prognosis, with only 30% overall survival. Hence, there is a substantial need for new therapies. The inability to control the metastatic progression of this localized cancer stems …

Unique Breast Cancer Features Within The Vietnamese Population, Polly Niravath, Melissa Bondy, Susan G. Hilsenbeck

Journal of Health Disparities Research and Practice

BACKGROUND: Breast cancer is known to be a heterogeneous disease across women, and even within individual tumors. However, relatively little is known about heterogeneity across cultures. There has been some evidence to suggest that Asian women are more likely to have HER2+ breast cancer than their Caucasian counterparts.

PURPOSE: The aim of this study was to further investigate the unique pattern of breast cancer incidence and subtype in the Vietnamese population.

METHODS: We retrospectively collected data on all Vietnamese women diagnosed with invasive breast cancer at the Lester & Sue Smith Breast Center in Houston, Texas over a four year …

Biological Functions Of Cdk5 And Potential Cdk5 Targeted Clinical Treatments., Alison Shupp, Mathew C. Casimiro, Richard G. Pestell

Department of Cancer Biology Faculty Papers

Cyclin dependent kinases are proline-directed serine/threonine protein kinases that are traditionally activated upon association with a regulatory subunit. For most CDKs, activation by a cyclin occurs through association and phosphorylation of the CDK's T-loop. CDK5 is unusual because it is not typically activated upon binding with a cyclin and does not require T-loop phosphorylation for activation, even though it has high amino acid sequence homology with other CDKs. While it was previously thought that CDK5 only interacted with p35 or p39 and their cleaved counterparts, Recent evidence suggests that CDK5 can interact with certain cylins, amongst other proteins, which modulate …

Predictive Screening Of M1 And M2 Macrophages Reveals The Immunomodulatory Effectiveness Of Post Spinal Cord Injury Azithromycin Treatment, John C. Gensel, Timothy J. Kopper, Bei Zhang, Michael B. Orr, William M. Bailey

Spinal Cord and Brain Injury Research Center Faculty Publications

Spinal cord injury (SCI) triggers a heterogeneous macrophage response that when experimentally polarized toward alternative forms of activation (M2 macrophages) promotes tissue and functional recovery. There are limited pharmacological therapies that can drive this reparative inflammatory state. In the current study, we used in vitrosystems to comprehensively defined markers of macrophages with known pathological (M1) and reparative (M2) properties in SCI. We then used these markers to objectively define the macrophage activation states after SCI in response to delayed azithromycin treatment. Mice were subjected to moderate-severe thoracic contusion SCI. Azithromycin or vehicle was administered beginning 30 minutes post-SCI and …

Pseudomonas Aeruginosa Sabotages The Generation Of Host Proresolving Lipid Mediators, Becca A. Flitter, Kelli L. Hvorecny, Emiko Ono, Taylor Eddens

Dartmouth Scholarship

Recurrent Pseudomonas aeruginosa infections coupled with robust, damaging neutrophilic inflammation characterize the chronic lung disease cystic fibrosis (CF). The proresolving lipid mediator, 15-epi lipoxin A4 (15-epi LXA4), plays a critical role in limiting neutrophil activation and tissue inflammation, thus promoting the return to tissue homeostasis. Here, we show that a secreted P. aeruginosa epoxide hydrolase, cystic fibrosis transmembrane conductance regulator inhibitory factor (Cif), can disrupt 15-epi LXA4 transcellular biosynthesis and function. In the airway, 15-epi LXA4 production is stimulated by the epithelial-derived eicosanoid 14,15-epoxyeicosatrienoic acid (14,15-EET). Cif sabotages the production of 15-epi LXA4 by rapidly hydrolyzing 14,15-EET into its cognate …

Increased Ros Production In Non-Polarized Mammary Epithelial Cells Induces Monocyte Infiltration In 3d Culture, Linzhang Li, Jie Chen, Gaofeng Xiong, Daret K. St. Clair, Wei Xu, Ren Xu

Markey Cancer Center Faculty Publications

Loss of epithelial cell polarity promotes cell invasion and cancer dissemination. Therefore, identification of factors that disrupt polarized acinar formation is crucial. Reactive oxygen species (ROS) drive cancer progression and promote inflammation. Here, we show that the non-polarized breast cancer cell line T4-2 generates significantly higher ROS levels than polarized S1 and T4R cells in three-dimensional (3D) culture, accompanied by induction of the nuclear factor κB (NF-κB) pathway and cytokine expression. Minimizing ROS in T4-2 cells with antioxidants reestablished basal polarity and inhibited cell proliferation. Introducing constitutively activated RAC1 disrupted cell polarity and increased ROS levels, indicating that RAC1 is …

3d Bioprinter + Electrospinner For Bone-Ligament Tissue Engineering, Sherif H. Aboubakr, Steven Nery, Lauren Long, Christopher A. Buksa, Chanju Fritch, Christina Salas

UNM Orthopaedic Research Journal

Modern 3D bioprinters have been shown to allow for precise control of structural geometry to build patientspecific scaffolds for tissue regeneration—primarily nonload- bearing tissue. However, 3D bioprinting is limited by cell viability, polymer cross-linking characteristics, and poor tensile properties. In comparison, electrospinning has been used to form fibrous structures with accelerated cellular maturation properties, improved growth and migration of cells, and increased tensile properties. Conversely, the mostly uncontrolled deposition of electrospun fibers can limit pore size and cell infiltration. In our Orthopaedic Biomechanics & Biomaterials Laboratory, a custom 3D Bioprinter + Electrospinner hybrid system (E-Spin Printer) was designed to merge …

Quantitative relationship between the magnitude of variation in minor histocompatibility antigens (mHA) and graft versus host disease (GVHD) pathophysiology in stem cell transplant (SCT) donor-recipient pairs (DRP) is not established. In order to elucidate this relationship, whole exome sequencing (WES) was performed on 27 HLA matched related (MRD), & 50 unrelated donors (URD), to identify nonsynonymous single nucleotide polymorphisms (SNPs). An average 2,463 SNPs were identified in MRD, and 4,287 in URD DRP (p
