Matrine Inhibits Cns Autoimmunity Through An Ifn-Β-Dependent Mechanism, Yaojuan Chu, Wendi Ma, Rodolfo Thome, Jie Dan Ping, Fangzhou Liu, Mengru Wang, Mingliang Zhang, Guang-Xian Zhang, Lin Zhu

Department of Neurology Faculty Papers

Matrine (MAT), a quinolizidine alkaloid component derived from the root of Sophora flavescens, suppresses experimental autoimmune encephalomyelitis (EAE), the animal model of multiple sclerosis (MS), by inducing the production of immunomodulatory molecules, e.g., IL-10. In an effort to find the upstream pathway(s) of the mechanism underlying these effects, we have tested certain upregulated immunomodulatory molecules. Among them, we found increased levels of IL-27 and IFN-β, one of the first-line MS therapies. Indeed, while low levels of IFN-β production in sera and type I interferon receptor (IFNAR1) expression in spinal cord of saline-treated control EAE mice were detected, they were significantly …

Community Health Sciences

Background: Anemia is a major public health concern among women of reproductive age leading to high maternal mortality in low- and middle-income countries. Of the prior studies conducted in Pakistan, most focused on large urban areas and did not explore the determinants of anemia among women of reproductive age (WRA) across socio-demographic, dietary, reproductive, and biological domains. Thus, we aimed to study the prevalence and determinants of anemia among WRA in rural Pakistan.
Methods: We conducted a cross-sectional study in the Thatta district of Pakistan from September 2018 to January 2019 and enrolled 150 non-pregnant, married women. Data collectors administered …

Mesencephalic Astrocyte-Derived Neurotrophic Factor (Manf) Regulates Neurite Outgrowth Through The Activation Of Akt/Mtor And Erk/Mtor Signaling Pathways, Wen Wen, Yongchao Wang, Hui Li, Hong Xu, Mei Xu, Jacqueline A. Frank, Murong Ma, Jia Luo

Pharmacology and Nutritional Sciences Faculty Publications

Neurite outgrowth is essential for brain development and the recovery of brain injury and neurodegenerative diseases. In this study, we examined the role of the neurotrophic factor MANF in regulating neurite outgrowth. We generated MANF knockout (KO) neuro2a (N2a) cell lines using clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 and demonstrated that MANF KO N2a cells failed to grow neurites in response to RA stimulation. Using MANF siRNA, this finding was confirmed in human SH-SY5Y neuronal cell line. Nevertheless, MANF overexpression by adenovirus transduction or addition of MANF into culture media facilitated the growth of longer neurites in RA-treated N2a …

Innate immune signaling through the NLRP3 inflammasome is activated by multiple diabetes-related stressors, but whether targeting the inflammasome is beneficial for diabetes is still unclear. Nucleoside reverse-transcriptase inhibitors (NRTI), drugs approved to treat HIV-1 and hepatitis B infections, also block inflammasome activation. Here, we show, by analyzing five health insurance databases, that the adjusted risk of incident diabetes is 33% lower in patients with NRTI exposure among 128,861 patients with HIV-1 or hepatitis B (adjusted hazard ratio for NRTI exposure, 0.673; 95% confidence interval, 0.638 to 0.710; P < 0.0001; 95% prediction interval, 0.618 to 0.734). Meanwhile, an NRTI, lamivudine, improves insulin sensitivity and reduces inflammasome activation in diabetic and insulin resistance-induced human cells, as well as in mice fed with high-fat chow; mechanistically, inflammasome-activating short interspersed nuclear element (SINE) transcripts are elevated, whereas SINE-catabolizing DICER1 is reduced, in diabetic cells and mice. These data suggest the possibility of repurposing an approved class of drugs for prevention of diabetes.

The Role Of Nerves In Skeletal Development, Adaptation, And Aging., Ryan E Tomlinson, Blaine A Christiansen, Adrienne A Giannone, Damian C Genetos

Department of Orthopaedic Surgery Faculty Papers

The skeleton is well-innervated, but only recently have the functions of this complex network in bone started to become known. Although our knowledge of skeletal sensory and sympathetic innervation is incomplete, including the specific locations and subtypes of nerves in bone, we are now able to reconcile early studies utilizing denervation models with recent work dissecting the molecular signaling between bone and nerve. In total, sensory innervation functions in bone much as it does elsewhere in the body-to sense and respond to stimuli, including mechanical loading. Similarly, sympathetic nerves regulate autonomic functions related to bone, including homeostatic remodeling and vascular …

Advanced fibrosis and portal hypertension influence short-term mortality. Lipocalin 2 (LCN2) regulates infection response and increases in liver injury. We explored the role of intrahepatic LCN2 in human alcoholic hepatitis (AH) with advanced fibrosis and portal hypertension and in experimental mouse fibrosis. We found hepatic LCN2 expression and serum LCN2 level markedly increased and correlated with disease severity and portal hypertension in patients with AH. In control human livers, LCN2 expressed exclusively in mononuclear cells, while its expression was markedly induced in AH livers, not only in mononuclear cells but also notably in hepatocytes. Lcn2−/− mice were protected from liver …

Department of Neurosurgery Faculty Papers

Sphenopalatine ganglion (SPG) stimulation has been shown to reversibly alter blood-brainbarrier (BBB) permeability. It is widely used for the treatment of cluster headaches in Europe and iswell tolerated in humans. The therapeutic potential for SPG stimulation in other central nervoussystem (CNS) diseases has yet to be explored. Glioblastoma Multiforme (GBM) remains one of themost difficult primary CNS neoplasms to treat, with an average survival of approximately 18 months atthe time of diagnosis. Since 2004, the gold standard of treatment for GBM in the United States includessurgery followed by treatment with temozolomide (TMZ) and radiation. We sought to determine ifSPG stimulation …

Renal Proximal Tubular Nemo Plays A Critical Role In Ischemic Acute Kidney Injury, Sang Jun Han, Ryan M. Williams, Mihwa Kim, Daniel A. Heller, Vivette D'Agati, Marc Schmidt-Supprian, H. Thomas Lee

Publications and Research

We determined that renal proximal tubular (PT) NF-κB essential modulator (NEMO) plays a direct and critical role in ischemic acute kidney injury (AKI) using mice lacking renal PT NEMO and by targeted renal PT NEMO inhibition with mesoscale nanoparticle–encapsulated NEMO binding peptide (NBP MNP). We subjected renal PT NEMO–deficient mice, WT mice, and C57BL/6 mice to sham surgery or 30 minutes of renal ischemia and reperfusion (IR). C57BL/6 mice received NBP MNP or empty MNP before renal IR injury. Mice treated with NBP MNP and mice deficient in renal PT NEMO were protected against ischemic AKI, having decreased renal tubular …

Microglial-Associated Responses To Comorbid Amyloid Pathology And Hyperhomocysteinemia In An Aged Knock-In Mouse Model Of Alzheimer's Disease, David J. Braun, Edgardo R. Dimayuga, Josh M. Morganti, Linda J. Van Eldik

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Elevated blood homocysteine levels, termed hyperhomocysteinemia (HHcy), is a prevalent risk factor for Alzheimer's disease (AD) in elderly populations. While dietary supplementation of B-vitamins is a generally effective method to lower homocysteine levels, there is little if any benefit to cognition. In the context of amyloid pathology, dietary-induced HHcy is known to enhance amyloid deposition and certain inflammatory responses. Little is known, however, about whether there is a more specific effect on microglia resulting from combined amyloid and HHcy pathologies.

METHODS: The present study used a knock-in mouse model of amyloidosis, aged to 12 months, given 8 weeks of …

Comparison Of Virulence Gene Carriage In Staphylococcus Aureus Isolates Colonizing Human Skin And Those Associated With Soft Tissue Osteoarticular Infections, Kylie Disch, Jon Femling, Parisa Mortaji, Kurt Schwalm, Aimee Yousey, Rebekkah Varjabedian, Darrell Dinwiddie, Walter Dehority

2020 Pediatric Research Forum Session

Background:

Osteoarticular infections (OAI), most commonly caused by S. aureus, cause extreme morbidity in children and may result in permanent sequelae (e.g. limb-length discrepancies). However, S. aureus is also a common colonizing bacteria of skin and a cause of soft tissue abscesses. Virulence determinants for S. aureus are likely complex, and may include the genetic composition of the isolate, the host immune response and the transcriptomic profile of the organism. A necessary first-step in characterizing these virulence factors includes assessing virulence gene carriage between S. aureus isolates from children with OAIs and from less virulent isolates.

Methods:

S. aureus …

Prenatal Alcohol Exposure And Placental Insufficiency Results In Reduced Neuronal Complexity In The Rat Prefrontal Cortex, Nathaniel Pavlik, Jessie Newville, Clement P. Jose, Suzy Davies, Jennifer Wagner, Jonathan Brigman, Daniel Savage, Jessie R. Maxwell

2020 Pediatric Research Forum Session

Prenatal Alcohol Exposure (PAE) can produce long-term neurodevelopmental deficits and impaired executive function. Alcohol exposure during gestation is associated with impaired fetal development caused by placental insufficiency. The impact following PAE and placental insufficiency (PI) remains unknown. Utilizing a three-dimensional (3D) Sholl analysis, we hypothesized that PAE+PI will result in decreased neuronal complexity within the frontal cortex, a region critical to executive functioning.

Pregnant Long-Evans rats voluntarily drank 5% ethanol or saccharin water until embryonic day 18 (E18) to mimic moderate PAE. On E19, a laparotomy was performed to occlude the uterine artery for 60 minutes to induce PI. The …

Psychology Faculty Articles and Research

Objective

Within the context of the United States opioid epidemic, some parents often fear the use of opioids to help manage their children's postoperative pain. As a possible consequence, parents often do not dispense optimal analgesic medications to their children after surgery, putting their children at risk of suffering from postsurgical pain. The objective of this research was to assess ethnicity as a predictor of both pain and opioid consumption, and to examine how Hispanic/Latinx and Non-Hispanic White parents alter their child's opioid consumption in response to significant postsurgical pain.

Methods

Participants were 254 children undergoing outpatient tonsillectomy and/or adenoidectomy …

Department of Dermatology and Cutaneous Biology Faculty Papers

Impaired wound healing complicates a wide range of diseases and represents a major cost to healthcare systems. Here we describe the use of discarded wound dressings as a novel, cost effective, accessible, and non-invasive method of isolating viable human cells present at the site of skin wounds. By analyzing 133 discarded wound dressings from 51 patients with the inherited skin-blistering disease epidermolysis bullosa (EB), we show that large numbers of cells, often in excess of 100 million per day, continually infiltrate wound dressings. We show, that the method is able to differentiate chronic from acute wounds, identifying significant increases in …

Journal Articles: Anesthesiology

Extracellular vesicles (EVs) are a broad, heterogeneous class of membranous lipid-bilayer vesicles that facilitate intercellular communication throughout the body. As important carriers of various types of cargo, including proteins, lipids, DNA fragments, and a variety of small noncoding RNAs, including miRNAs, mRNAs, and siRNAs, EVs may play an important role in the development of addiction and other neurological pathologies, particularly those related to HIV. In this review, we summarize the findings of EV studies in the context of methamphetamine (METH), cocaine, nicotine, opioid, and alcohol use disorders, highlighting important EV cargoes that may contribute to addiction. Additionally, as HIV and …

Endogenous Cyclin D1 Promotes The Rate Of Onset And Magnitude Of Mitogenic Signaling Via Akt1 Ser473 Phosphorylation., Ke Chen, Xuanmao Jiao, Agnese Di Rocco, Duanwen Shen, Shaohua Xu, Adam Ertel, Zuoren Yu, Gabriele Di Sante, Min Wang, Zhiping Li, Timothy G Pestell, Mathew C Casimiro, Emmanuel Skordalakes, Samuel Achilefu, Richard G Pestell

Department of Cancer Biology Faculty Papers

Cyclin D1 encodes the regulatory subunit of a holoenzyme that phosphorylates RB and functions as a collaborative nuclear oncogene. The serine threonine kinase Akt plays a pivotal role in the control of cellular metabolism, survival, and mitogenic signaling. Herein, Akt1-mediated phosphorylation of downstream substrates in the mammary gland is reduced by cyclin D1 genetic deletion and is induced by mammary-gland-targeted cyclin D1 overexpression. Cyclin D1 is associated with Akt1 and augments the rate of onset and maximal cellular Akt1 activity induced by mitogens. Cyclin D1 is identified in a cytoplasmic-membrane-associated pool, and cytoplasmic-membrane-localized cyclin D1-but not nuclear-localized cyclin D1-recapitulates Akt1 …

Heparin-like substances (HLS) have been described in various clinical situations, including in settings of liver disease associated with infection, transplant, and metastasis. HLS are generally attributed to circulating glycosaminoglycans. Initial results for this patient showed coagulopathy due to liver disease without HLS. Two weeks after liver transplantation, a 10 year-old female with liver failure patient began to bleed from catheter insertion sites, mouth, and nares and HLS was suspected. The patient subsequently died and these clinical samples resulted in the isolation of a single heparan sulfate (HS) present at high concentrations in the plasma. Analysis of this HS showed it …

Department of Medical Oncology Faculty Papers

Chondrosarcoma is the second most common primary bone malignancy, representing one fourth of all primary bone sarcomas. It is typically resistant to radiation and chemotherapy treatments. However, the molecular mechanisms that contribute to cancer aggressiveness in chondrosarcomas remain poorly characterized. Here, we studied the role of mitochondrial transporters in chondrosarcoma aggressiveness including chemotherapy resistance. Histological grade along with stage are the most important prognostic biomarkers in chondrosarcoma. We found that high-grade human chondrosarcoma tumors have higher expression of the mitochondrial protein, translocase of the outer mitochondrial membrane complex subunit 20 (TOMM20), compared to low-grade tumors. TOMM20 overexpression in human chondrosarcoma …

Encoding The Odor Of Cigarette Smoke, Timothy S. Mcclintock, Naazneen Khan, Yelena Alimova, Madeline Aulisio, Dong Y. Han, Patrick Breheny

Physiology Faculty Publications

The encoding of odors is believed to begin as a combinatorial code consisting of distinct patterns of responses from odorant receptors (ORs), trace-amine associated receptors (TAARs), or both. To determine how specific response patterns arise requires detecting patterns in vivo and understanding how the components of an odor, which are nearly always mixtures of odorants, give rise to parts of the pattern. Cigarette smoke, a common and clinically relevant odor consisting of > 400 odorants, evokes responses from 144 ORs and 3 TAARs in freely behaving male and female mice, the first example of in vivo responses of both ORs and …
