Roles Of Mir-223 In Platelet Function And High On-Treatment Platelet Reactivity: A Brief Report And Review, Shayan Askari, Lawrence E. Goldfinger

Cardeza Foundation for Hematologic Research

BACKGROUND: Platelets are highly enriched in microRNAs (miRNAs), which are genomically encoded 19-25 nucleotide non-coding RNAs that target complementary mRNAs through total or near-total base pairing. MiR-223 is among the most abundant miRNAs in human and murine platelets, but despite ongoing investigations in recent years, miR-223 roles in platelet physiology and its putative roles in high on-treatment platelet reactivity (HTPR) remain controversial, as studies showed varying findings.

OBJECTIVES: In the current hybrid review/report, we aim to compare studies that investigated miR-223 in platelet function and HTPR. Additionally, we briefly report our own findings on murine miR-223-deficient platelets.

METHODS: We have …

Anti-retroviral therapy (ART) has decreased human immunodeficiency virus (HIV)-1-associated morbidity. However, despite ART, immune cells remain latently infected, leading to chronic inflammation and HIV-1-associated comorbidities. New strategies are needed to target viral proteins and inflammation. We found activation of Notch3 in renal cells of the HIV-1 transgenic mouse model (HIV-Tg26) and in patients with HIV-associated nephropathy. We hypothesized that targeting NOTCH3 activation constitutes an effective therapy for HIV-related chronic kidney disease. We generated HIV-Tg26 mice with Notch3 knocked out (Tg-N3KO). Compared to HIV-Tg26 mice at 3 months, Tg-N3KO mice showed a marked reduction in renal injury, skin lesions and mortality …

Perinuclear Organelle Trauma At The Nexus Of Cardiomyopathy Pathogenesis Arising From Loss Of Function Lmna Mutation, Jason C. Choi

Center for Translational Medicine Faculty Papers

Over the past 25 years, nuclear envelope (NE) perturbations have been reported in various experimental models with mutations in the LMNA gene. Although the hypothesis that NE perturbations from LMNA mutations are a fundamental feature of striated muscle damage has garnered wide acceptance, the molecular sequalae provoked by the NE damage and how they underlie disease pathogenesis such as cardiomyopathy (LMNA cardiomyopathy) remain poorly understood. We recently shed light on one such consequence, by employing a cardiomyocyte-specific Lmna deletion in vivo in the adult heart. We observed extensive NE perturbations prior to cardiac function deterioration with collateral damage in the …

Center for Translational Medicine Faculty Papers

The study of the senile osteoporosis in men still lags significantly behind that in women. The changes of protein molecule levels and their relationships with bone loss remain poorly understood. In the present study, we used C57BL/6J male mice at ages from 3 to 24 mo to delineate the mechanisms of aging effects on bone loss. We used the microcomputed tomography, mechanical testing, histomorphometry assays, and detection of serum levels of undercarboxylated osteocalcin (ucOcn) and carboxylated osteocalcin (cOcn) to assess bone mass changes and their relationships with the ratios of ucOcn-to-cOcn in mice from different age groups. The results showed …

Cocaine-Induced Dna-Dependent Protein Kinase Relieves Rnap Ii Pausing By Promoting Trim28 Phosphorylation And Rnap Ii Hyperphosphorylation To Enhance Hiv Transcription, Adhikarimayum Lakhikumar Sharma, Priya Tyagi, Meenata Khumallambam, Mudit Tyagi

Center for Translational Medicine Faculty Papers

Drug abuse continues to pose a significant challenge in HIV control efforts. In our investigation, we discovered that cocaine not only upregulates the expression of the DNA-dependent protein kinase (DNA-PK) but also augments DNA-PK activation by enhancing its phosphorylation at S2056. Moreover, DNA-PK phosphorylation triggers the higher localization of the DNA-PK into the nucleus. The finding that cocaine increases the nuclear localization of the DNA-PK provides further support to our observation of enhanced DNA-PK recruitment at the HIV long terminal repeat (LTR) following cocaine exposure. By activating and facilitating the nuclear localization of the DNA-PK, cocaine effectively orchestrates multiple stages …

The Importance Of Including Maternal Immune Activation In Animal Models Of Hypoxic-Ischemic Encephalopathy, Bailey Collins, Elise A. Lemanski, Elizabeth Wright-Jin

Department of Medicine Faculty Papers

Hypoxic-ischemic encephalopathy (HIE) is a perinatal brain injury that is the leading cause of cerebral palsy, developmental delay, and poor cognitive outcomes in children born at term, occurring in about 1.5 out of 1000 births. The only proven therapy for HIE is therapeutic hypothermia. However, despite this treatment, many children ultimately suffer disability, brain injury, and even death. Barriers to implementation including late diagnosis and lack of resources also lead to poorer outcomes. This demonstrates a critical need for additional treatments for HIE, and to facilitate this, we need translational models that accurately reflect risk factors and interactions present in …

Recovery After Human Bone Marrow Mesenchymal Stem Cells (Hbm-Mcs)-Derived Extracellular Vesicles (Evs) Treatment In Post-Mcao Rats Requires Repeated Handling, Yolanda Gomez-Galvez, Malvika Gupta, Mandeep Kaur, Salvatore Fusco, Maria Vittoria Podda, Claudio Grassi, Amit K. Srivastava, Lorraine Iacovitti, Elena Blanco-Suarez

Farber Institute for Neuroscience Faculty Papers

Rehabilitation is the only current intervention that improves sensorimotor function in ischemic stroke patients, similar to task-specific intensive training in animal models of stroke. Bone marrow mesenchymal stem cells (BM-MSCs)-derived extracellular vesicles (EVs) are promising in restoring brain damage and function in stroke models. Additionally, the non-invasive intranasal route allows EVs to reach the brain and target specific ischemic regions. Yet unclear is how handling might enhance recovery or influence other therapies such as EVs after stroke. We used the transient middle cerebral artery occlusion (MCAO) model of stroke in rats to assess how intensive handling alone, in the form …

Genetic Knock-In Of Eif2ak3 Variants Reveals Differences In Perk Activity In Mouse Liver And Pancreas Under Endoplasmic Reticulum Stress, Shivesh Ghura, Noah R. Beratan, Xinglong Shi, Elena Alvarez-Periel, Sarah E. Bond Newton, Cagla Akay-Espinoza, Kelly L. Jordan-Sciutto

Farber Institute for Neuroscience Staff Papers and Presentations

Common single-nucleotide variants (SNVs) of eukaryotic translation initiation factor 2 alpha kinase 3 (EIF2AK3) slightly increase the risk of disorders in the periphery and the central nervous system. EIF2AK3 encodes protein kinase RNA-like endoplasmic reticulum kinase (PERK), a key regulator of ER stress. Three exonic EIF2AK3 SNVs form the PERK-B haplotype, which is present in 28% of the global population. Importantly, the precise impact of these SNVs on PERK activity remains elusive. In this study, we demonstrate that PERK-B SNVs do not alter PERK expression or basal activity in vitro and in the novel triple knock-in mice expressing the exonic …

Downregulation Of Piezo2 In The Detrusor Of Men With Bladder Outlet Obstruction And Its Association With Urinary Retention And Decreased Bladder Compliance, Carlos Henrique Suzuki Bellucci, Thiago Souto Hemerly, Luisa Resende Tenório De Albuquerque, Ruan Pimenta, Vanessa Guimaraes Schreiter, Sabrina Thalita Dos Reis, Jose De Bessa Jr, Katia Ramos Moreira Leite, Alberto Antunes, Boopathi Ettickan, William C. Nahas, Cristiano Mendes Gomes

Center for Translational Medicine Faculty Papers

PURPOSE: Recent research has highlighted the mechanotransducer PIEZO2 as a crucial factor in lower urinary tract function, demonstrating associations with bladder compliance (BC), bladder wall thickening, and elevated bladder pressure. We explored the hypothesis that PIEZO2 expression may be associated with lower urinary tract dysfunction in men with bladder outlet obstruction (BOO) due to benign prostatic hyperplasia (BPH).

METHODS: The study included a consecutive series of patients undergoing open prostatectomy for BPH at our hospital between September 2014 and January 2016. All participants underwent comprehensive preoperative evaluations, including urodynamic assessments. During prostatectomy, a full-thickness fragment of the bladder wall was …

Inhibiting Endothelial Cell Mst1 Attenuates Acute Lung Injury In Mice, Zhi-Fu Guo, Nopprarat Tongmuang, Chao Li, Chen Zhang, Louis Hu, Daniel Capreri, Mei-Xing Zuo, Ross Summer, Jianxin Sun

Center for Translational Medicine Faculty Papers

Lung endothelium plays a pivotal role in the orchestration of inflammatory responses to acute pulmonary insults. Mammalian sterile 20-like kinase 1 (Mst1) is a serine/threonine kinase that has been shown to play an important role in the regulation of apoptosis, stress responses, and organ growth. This study investigated the role of Mst1 in lung endothelial activation and acute lung injury (ALI). We found that Mst1 was significantly activated in inflamed lung endothelial cells (ECs) and mouse lung tissues. Overexpression of Mst1 promoted nuclear factor κ-B (NF-κB) activation through promoting JNK and p38 activation in lung ECs. Inhibition of Mst1 by …

Krais, Bernadette Taberi, Umeshkumar Vekariya, Marissa L Calbert, Tomasz Skorski, Neil Johnson, Xiaojiang S. Chen, Richard T. Pomerantz

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

DNA polymerase theta (Polθ) is a DNA helicase-polymerase protein that facilitates DNA repair and is synthetic lethal with homology-directed repair (HDR) factors. Thus, Polθ is a promising precision oncology drug-target in HDR-deficient cancers. Here, we characterize the binding and mechanism of action of a Polθ helicase (Polθ-hel) small-molecule inhibitor (AB25583) using cryo-EM. AB25583 exhibits 6 nM IC50 against Polθ-hel, selectively kills BRCA1/2-deficient cells, and acts synergistically with olaparib in cancer cells harboring pathogenic BRCA1/2 mutations. Cryo-EM uncovers predominantly dimeric Polθ-hel:AB25583 complex structures at 3.0-3.2 Å. The structures reveal a binding-pocket deep inside the helicase central-channel, which underscores the high specificity …

Molecular Mechanism Of Bitter Taste Receptor Agonist-Mediated Relaxation Of Airway Smooth Muscle, Stanley Conaway, Weiliang Huang, Miguel A. Hernandez-Lara, Maureen A. Kane, Raymond B. Penn, Deepak A. Deshpande

Center for Translational Medicine Faculty Papers

G-protein-coupled receptors (GPCRs) belonging to the type 2 taste receptors (TAS2Rs) family are predominantly present in taste cells to allow the perception of bitter-tasting compounds. TAS2Rs have also been shown to be expressed in human airway smooth muscle (ASM), and TAS2R agonists relax ASM cells and bronchodilate airways despite elevating intracellular calcium. This calcium “paradox” (calcium mediates contraction by pro-contractile Gq-coupled GPCRs) and the mechanisms by which TAS2R agonists relax ASM remain poorly understood. To gain insight into pro-relaxant mechanisms effected by TAS2Rs, we employed an unbiased phosphoproteomic approach involving dual-mass spectrometry to determine differences in the phosphorylation of contractile-related …

Small-Molecule Disruptors Of The Interaction Between Calcium- And Integrin-Binding Protein 1 And Integrin Α, Kalyan Golla, Adam Yasgar, Manjuprasanna Voddarahally Nagaraju, Meghna U. Naik, Bolormaa Baljinnyam, Alexey V. Zakharov, Sankalp Jain, Ganesha Rai, Ajit Jadhav, Anton Simeonov, Ulhas P. Naik

Cardeza Foundation for Hematologic Research

Thrombosis, a key factor in most cardiovascular diseases, is a major contributor to human mortality. Existing antithrombotic agents carry a risk of bleeding. Consequently, there is a keen interest in discovering innovative antithrombotic agents that can prevent thrombosis without negatively impacting hemostasis. Platelets play crucial roles in both hemostasis and thrombosis. We have previously characterized calcium- and integrin-binding protein 1 (CIB1) as a key regulatory molecule that regulates platelet function. CIB1 interacts with several platelet proteins including integrin αIIbβ3, the major glycoprotein receptor for fibrinogen on platelets. Given that CIB1 regulates platelet function through its interaction with αIIbβ3, we developed …

Keratin 17 Modulates The Immune Topography Of Pancreatic Cancer, Lyanne Delgado-Coka, Michael Horowitz, Mariana Torrente-Goncalves, Lucia Roa-Peña, Cindy Leiton, Mahmudul Hasan, Sruthi Babu, Danielle Fassler, Jaymie Oentoro, Ji-Dong Bai, Emanuel Petricoin, Lynn Matrisian, Edik Matthew Blais, Natalia Marchenko, Felicia Allard, Wei Jiang, Brent Larson, Andrew Hendifar, Chao Chen, Shahira Abousamra, Dimitris Samaras, Tahsin Kurc, Joel Saltz, Luisa Escobar-Hoyos, Kenneth Shroyer

Kimmel Cancer Center Faculty Papers

BACKGROUND: The immune microenvironment impacts tumor growth, invasion, metastasis, and patient survival and may provide opportunities for therapeutic intervention in pancreatic ductal adenocarcinoma (PDAC). Although never studied as a potential modulator of the immune response in most cancers, Keratin 17 (K17), a biomarker of the most aggressive (basal) molecular subtype of PDAC, is intimately involved in the histogenesis of the immune response in psoriasis, basal cell carcinoma, and cervical squamous cell carcinoma. Thus, we hypothesized that K17 expression could also impact the immune cell response in PDAC, and that uncovering this relationship could provide insight to guide the development of …

Mutations in the LMNA gene encoding lamins A/C cause an array of tissue-selective diseases, with the heart being the most commonly affected organ. Despite progress in understanding the perturbations emanating from LMNA mutations, an integrative understanding of the pathogenesis underlying cardiac dysfunction remains elusive. Using a novel conditional deletion model capable of translatome profiling, we observed that cardiomyocyte-specific Lmna deletion in adult mice led to rapid cardiomyopathy with pathological remodeling. Before cardiac dysfunction, Lmna-deleted cardiomyocytes displayed nuclear abnormalities, Golgi dilation/fragmentation, and CREB3-mediated stress activation. Translatome profiling identified MED25 activation, a transcriptional cofactor that regulates Golgi stress. Autophagy is disrupted …

Molecular Therapy And Nucleic Acid Adeno-Associated Virus-Based Gene Therapy Delivering Combinations Of Two Growth-Associated Genes To Mps Iva Mice, Estera Rintz, Betul Celik, Nidhi Fnu, Angélica María Herreño-Pachón, Shaukat Khan, Shunji Tomatsu, Eliana Benincore-Flórez

Department of Medicine Faculty Papers

Mucopolysaccharidosis type IVA (MPS IVA) is caused by a deficiency of the galactosamine (N-acetyl)-6-sulfatase (GALNS) enzyme responsible for the degradation of specific glycosaminoglycans (GAGs). The progressive accumulation of GAGs leads to various skeletal abnormalities (short stature, hypoplasia, tracheal obstruction) and several symptoms in other organs. To date, no treatment is effective for patients with bone abnormalities. To improve bone pathology, we propose a novel combination treatment with the adeno-associated virus (AAV) vectors expressing GALNS enzyme and a natriuretic peptide C (CNP; NPPC gene) as a growth-promoting agent for MPS IVA. In this study, an MPS IVA mouse model was treated …

Acetaminophen (ACE) is a widely used analgesic and antipyretic drug with various applications, from pain relief to fever reduction. Recent studies have reported equivocal effects of habitual ACE intake on exercise performance, muscle growth, and risks to bone health. Thus, this study aimed to assess the impact of a 6-week, low-dose ACE regimen on muscle and bone adaptations in exercising and non-exercising rats. Nine-week-old Wistar rats (n = 40) were randomized to an exercise or control (no exercise) condition with ACE or without (placebo). For the exercise condition, rats ran 5 days per week for 6 weeks at a 5% …

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

BACKGROUND: Acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF) affect a significant proportion of patients with IPF. There are limited data to inform therapeutic strategies for AE-IPF, despite its high mortality. We discuss the rationale and design of STRIVE-IPF, a randomized, multi-center, open-label Phase IIb clinical trial to determine the efficacy of combined therapeutic plasma exchange (TPE), rituximab, and intravenous immunoglobulin (IVIG), in comparison to treatment as usual (TAU), among patients with acute IPF exacerbations.

METHODS: The STRIVE-IPF trial will randomize 51 patients among five sites in the United States. The inclusion criteria have been designed to select a study population …

Center for Translational Medicine Faculty Papers

BACKGROUND: Nur77 belongs to the member of orphan nuclear receptor 4A family that plays critical roles in maintaining vascular homeostasis. This study aims to determine whether Nur77 plays a role in attenuating vascular dysfunction, and if so, to determine the molecular mechanisms involved.

METHODS: Both Nur77 knockout (Nur77 KO) and Nur77 endothelial specific transgenic mice (Nur77-Tg) were employed to examine the functional significance of Nur77 in vascular endothelium in vivo. Endothelium-dependent vasodilatation to acetylcholine (Ach) and reactive oxygen species (ROS) production was determined under inflammatory and high glucose conditions. Expression of genes was determined by real-time PCR and western blot …

Pkcε Activator Protects Hippocampal Microvascular Disruption And Memory Defect In 3×Tg-Alzheimer's Disease Mice With Cerebral Microinfarcts, Huaixing Wang, Zongxiu Zhang, Jarin Hongpaisan

Center for Translational Medicine Faculty Papers

BACKGROUND: Current evidence suggests that microvessel disease is involved in Alzheimer's disease (AD). Cerebrovascular disease correlates with cardiovascular disease and is complicated in ≈40% of AD patients. The protein kinase C (PKC) ε activator DCPLA can stimulate human antigen (Hu) R that prevents degradation and promotes the translation of mitochondrial Mn-superoxide dismutase (MnSOD) and vascular endothelial growth factor-A (VEGF) mRNAs.

METHODS: To induce brain microinfarcts, we injected triple transgenic (3×Tg) and wild-type (WT) control mice with microbeads (20 μm caliber) into common carotid arteries, with or without the DCPLA-ME (methyl-ester) for 2 weeks. After water maze training, mice at 16 …

Interleukin 31 Receptor Α Promotes Smooth Muscle Cell Contraction And Airway Hyperresponsiveness In Asthma, Santhoshi Akkenepally, Dan Yombo, Sanjana Yerubandi, Geereddy Bhanuprakash Reddy, Deepak Deshpande, Francis Mccormack, Satish Madala

Center for Translational Medicine Faculty Papers

Asthma is a chronic inflammatory airway disease characterized by airway hyperresponsiveness (AHR), inflammation, and goblet cell hyperplasia. Multiple cytokines, including IFNγ, IL-4, and IL-13 are associated with asthma; however, the mechanisms underlying the effects of these cytokines remain unclear. Here, we report a significant increase in the expression of IL-31RA, but not its cognate ligand IL-31, in mouse models of allergic asthma. In support of this, IFNγ, IL-4, and IL-13 upregulated IL-31RA but not IL-31 in both human and mice primary airway smooth muscle cells (ASMC) isolated from the airways of murine and human lungs. Importantly, the loss of IL-31RA …

Increase In Hnrnpa1 Expression Suffices To Kill Motor Neurons In Transgenic Rats, Xionghao Liu, Tingting Zhang, Qinxue Wu, Cao Huang, Xu-Gang Xia, Hongxia Zhou, Bo Huang

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

A dominant mutation in hnRNPA1 causes amyotrophic lateral sclerosis (ALS), but it is not known whether this mutation leads to motor neuron death through increased or decreased function. To elucidate the relationship between pathogenic hnRNPA1 mutation and its native function, we created novel transgenic rats that overexpressed wildtype rat hnRNPA1 exclusively in motor neurons. This targeted expression of wildtype hnRNPA1 caused severe motor neuron loss and subsequent denervation muscle atrophy in transgenic rats that recapitulated the characteristics of ALS. These findings demonstrate that the augmentation of hnRNPA1 expression suffices to trigger motor neuron degeneration and the manifestation of ALS-like phenotypes. …

Immune Responses Induced At One Hour Post Cataract Surgery Wounding Of The Chick Lens, Jodirae Dedreu, Morgan Basta, Janice Walker, Sue Menko

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

While the lens is an avascular tissue with an immune-privileged status, studies have now revealed that there are immune responses specifically linked to the lens. The response to lens injury, such as following cataract surgery, has been shown to involve the activation of the resident immune cell population of the lens and the induction of immunomodulatory factors by the wounded epithelium. However, there has been limited investigation into the immediate response of the lens to wounding, particularly those induced factors that are intrinsic to the lens and its associated resident immune cells. Using an established chick embryo ex vivo cataract …

Epicutaneous Sensitization To The Phytocannabinoid Β-Caryophyllene Induces Pruritic Inflammation, Saadet Inan, Sara J Ward, Citlalli T Baltazar, Gabrielle A. Peruggia, Elham Javed, Ajay P. Nayak

Center for Translational Medicine Faculty Papers

In recent years, there has been increased accessibility to cannabis for recreational and medicinal use. Incidentally, there has been an increase in reports describing allergic reactions to cannabis including exacerbation of underlying asthma. Recently, multiple protein allergens were discovered in cannabis, yet these fail to explain allergic sensitization in many patients, particularly urticaria and angioedema. Cannabis has a rich chemical profile including cannabinoids and terpenes that possess immunomodulatory potential. We examined whether major cannabinoids of cannabis such as cannabidiol (CBD) and the bicyclic sesquiterpene beta-caryophyllene (β-CP) act as contact sensitizers. The repeated topical application of mice skin with β-CP at …
