Chaperone Hsp47 Drives Malignant Growth And Invasion By Modulating An Ecm Gene Network, Jieqing Zhu, Gaofeng Xiong, Hanjiang Fu, B. Mark Evers, Binhua P. Zhou, Ren Xu

Markey Cancer Center Faculty Publications

The extracellular matrix (ECM) is a determining factor in the tumor microenvironment that restrains or promotes malignant growth. In this report, we show how the molecular chaperone protein Hsp47 functions as a nodal hub in regulating an ECM gene transcription network. A transcription network analysis showed that Hsp47 expression was activated during breast cancer development and progression. Hsp47 silencing reprogrammed human breast cancer cells to form growth-arrested and/or noninvasive structures in 3D cultures, and to limit tumor growth in xenograft assays by reducing deposition of collagen and fibronectin. Coexpression network analysis also showed that levels of microRNA(miR)-29b and -29c were …

The adaptive immune response to vaccination or infection can lead to the production of specific antibodies to neutralize the pathogen or recruit innate immune effector cells for help. The non-neutralizing role of antibodies in stimulating effector cell responses may have been a key mechanism of the protection observed in the RV144 HIV vaccine trial. In an extensive investigation of a rich set of data collected from RV144 vaccine recipients, we here employ machine learning methods to identify and model associations between antibody features (IgG subclass and antigen specificity) and effector function activities (antibody dependent cellular phagocytosis, cellular cytotoxicity, and cytokine …

Transcriptional Activity Of The Islet Β Cell Factor Pdx1 Is Augmented By Lysine Methylation Catalyzed By The Methyltransferase Set7/9, Aarthi V. Maganti, Bernhard Maier, Sarah A. Tersey, Megan L. Sampley, Amber L. Mosley, Sabire Özcan, Boobalan Pachaiyappan, Patrick M. Woster, Chad S. Hunter, Roland Stein, Raghavendra G. Mirmira

Molecular and Cellular Biochemistry Faculty Publications

The transcription factor Pdx1 is crucial to islet β cell function and regulates target genes in part through interaction with coregulatory factors. Set7/9 is a Lys methyltransferase that interacts with Pdx1. Here we tested the hypothesis that Lys methylation of Pdx1 by Set7/9 augments Pdx1 transcriptional activity. Using mass spectrometry and mutational analysis of purified proteins, we found that Set7/9 methylates the N-terminal residues Lys-123 and Lys-131 of Pdx1. Methylation of these residues occurred only in the context of intact, full-length Pdx1, suggesting a specific requirement of secondary and/or tertiary structural elements for catalysis by Set7/9. Immunoprecipitation assays and mass …

Practical Management Of Anticoagulation In Patients With Atrial Fibrillation., Richard J Kovacs, Greg C Flaker, Sherry J Saxonhouse, John U. Doherty, Kim K Birtcher, Adam Cuker, Bruce L Davidson, Robert P Giugliano, Christopher B Granger, Amir K Jaffer, Bella H Mehta, Edith Nutescu, Kim A Williams

Department of Medicine Faculty Papers

Anticoagulation for atrial fibrillation has become more complex due to the introduction of new anticoagulant agents, the number and kinds of patients requiring therapy, and the interactions of those patients in the matrix of care. The management of anticoagulation has become a "team sport" involving multiple specialties in multiple sites of care. The American College of Cardiology, through the College's Anticoagulation Initiative, convened a roundtable of experts from multiple specialties to discuss topics important to the management of patients requiring anticoagulation and to make expert recommendations on issues such as the initiation and interruption of anticoagulation, quality of anticoagulation care, …

Motor Skill Learning Between Selection And Execution., Jörn Diedrichsen, Katja Kornysheva

Brain and Mind Institute Researchers' Publications

Learning motor skills evolves from the effortful selection of single movement elements to their combined fast and accurate production. We review recent trends in the study of skill learning which suggest a hierarchical organization of the representations that underlie such expert performance, with premotor areas encoding short sequential movement elements (chunks) or particular component features (timing/spatial organization). This hierarchical representation allows the system to utilize elements of well-learned skills in a flexible manner. One neural correlate of skill development is the emergence of specialized neural circuits that can produce the required elements in a stable and invariant fashion. We discuss …

Antibody-Mediated Targeting Of Iron Oxide Nanoparticles To The Folate Receptor Alpha Increases Tumor Cell Association In Vitro And In Vivo, Christian Ndong, Seiko Toraya-Brown, Katsiaryna Kekalo, Ian Baker, Tillman U. Gerngross, Steven N. Fiering, Karl E. Griswold

Dartmouth Scholarship

Active molecular targeting has become an important aspect of nanoparticle development for oncology indications. Here, we describe molecular targeting of iron oxide nanoparticles (IONPs) to the folate receptor alpha (FOLRα) using an engineered antibody fragment (Ffab). Compared to control nanoparticles targeting the non-relevant botulinum toxin, the Ffab-IONP constructs selectively accumulated on FOLRα-overexpressing cancer cells in vitro, where they exhibited the capacity to internalize into intracellular vesicles. Similarly, Ffab-IONPs homed to FOLRα-positive tumors upon intraperitoneal administration in an orthotopic murine xenograft model of ovarian cancer, whereas negative control particles showed no detectable tumor accumulation. Interestingly, Ffab-IONPs built with custom 120 nm …

Preliminary Analysis Of In Utero Low-Level Arsenic Exposure And Fetal Growth Using Biometric Measurements Extracted From Fetal Ultrasound Reports, Matthew A. Davis, John Higgins, Zhigang Li, Diane Gilbert-Diamond, Emily R. Baker, Amar Das, Margaret R. Karagas

Dartmouth Scholarship

Background: Early life exposure to arsenic is associated with decreased birth weight in highly exposed populations but little is known about effects of low-level arsenic exposure on growth in utero.

Methods: Using a sample of 272 pregnancies from New Hampshire we obtained biometric measurements directly from fetal ultrasound reports commonly found in electronic medical records. We used information extraction methods to develop and validate an automated approach for mining biometric measurements from the text of clinical reports. As a preliminary analysis, we examined associations between in utero low-level arsenic exposure (as measured by maternal urinary arsenic concentration) and fetal growth …

G9a Is Essential For Emt-Mediated Metastasis And Maintenance Of Cancer Stem Cell-Like Characters In Head And Neck Squamous Cell Carcinoma, Shuli Liu, Dongxia Ye, Wenzheng Guo, Wenwen Yu, Yue He, Jingzhou Hu, Yanan Wang, Ling Zhang, Yueling Liao, Hongyong Song, Shuangshuang Zhong, Dongliang Xu, Huijing Yin, Beibei Sun, Xiaofei Wang, Jingyi Liu, Yadi Wu, Binhua P. Zhou, Zhiyuan Zhang, Jiong Deng

Markey Cancer Center Faculty Publications

Head and neck squamous cell carcinoma (HNSCC) is a particularly aggressive cancer with poor prognosis, largely due to lymph node metastasis and local recurrence. Emerging evidence suggests that epithelial-to-mesenchymal transition (EMT) is important for cancer metastasis, and correlated with increased cancer stem cells (CSCs) characteristics. However, the mechanisms underlying metastasis to lymph nodes in HNSCC is poorly defined. In this study, we show that E-cadherin repression correlates with cancer metastasis and poor prognosis in HNSCC. We found that G9a, a histone methyltransferase, interacts with Snail and mediates Snail-induced transcriptional repression of E-cadherin and EMT, through methylation of histone H3 lysine-9 …

Review Of Nanomaterials In Dentistry: Interactions With The Oral Microenvironment, Clinical Applications, Hazards, And Benefits., Alexandros Besinis, Peralta T De, Christopher J. Tredwin, Richard D. Handy

School of Engineering, Computing and Mathematics

Interest in the use of engineered nanomaterials (ENMs) as either nanomedicines or dental materials/devices in clinical dentistry is growing. This review aims to detail the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks. The flow rate and quality of saliva are likely to influence the behavior of ENMs in the oral cavity, but how the protein corona formed on the ENMs will alter bioavailability, or interact with …

Kalkitoxin Inhibits Angiogenesis, Disrupts Cellular Hypoxic Signaling, And Blocks Mitochondrial Electron Transport In Tumor Cells, J B. Morgan, Yang Liu, Veena Coothankandaswamy, Fakhri Mahdi, Mika B. Jekabsons, William H. Gerwick, Frederick A. Valeriote, Yu-Dong Zhou, Dale G. Nagle

Hematology/Oncology Articles

The biologically active lipopeptide kalkitoxin was previously isolated from the marine cyanobacterium Moorea producens (Lyngbya majuscula). Kalkitoxin exhibited N-methyl-D-aspartate (NMDA)-mediated neurotoxicity and acted as an inhibitory ligand for voltage-sensitive sodium channels in cultured rat cerebellar granule neurons. Subsequent studies revealed that kalkitoxin generated a delayed form of colon tumor cell cytotoxicity in 7-day clonogenic cell survival assays. Cell line- and exposure time-dependent cytostatic/cytotoxic effects were previously observed with mitochondria-targeted inhibitors of hypoxia-inducible factor-1 (HIF-1). The transcription factor HIF-1 functions as a key regulator of oxygen homeostasis. Therefore, we investigated the ability of kalkitoxin to inhibit hypoxic signaling in human tumor …

Predicted Protein-Protein Interactions In The Moss Physcomitrella Patens: A New Bioinformatic Resource., Scott Schuette, Brian Piatkowski, Aaron Corley, Daniel Lang, Matt Geisler

Publications

BACKGROUND: Physcomitrella patens, a haploid dominant plant, is fast becoming a useful molecular genetics and bioinformatics tool due to its key phylogenetic position as a bryophyte in the post-genomic era. Genome sequences from select reference species were compared bioinformatically to Physcomitrella patens using reciprocal blasts with the InParanoid software package. A reference protein interaction database assembled using MySQL by compiling BioGrid, BIND, DIP, and Intact databases was queried for moss orthologs existing for both interacting partners. This method has been used to successfully predict interactions for a number of angiosperm plants.

RESULTS: The first predicted protein-protein interactome for a bryophyte …

Metabolic Reprogramming Of Cancer-Associated Fibroblasts By Idh3Α Downregulation, Daoxiang Zhang, Yongbin Wang, Zhimin Shi, Jingyi Liu, Pan Sun, Xiaodan Hou, Jian Zhang, Shimin Zhao, Binhua P. Zhou, Jun Mi

Markey Cancer Center Faculty Publications

Cancer-associated fibroblasts (CAFs) provide critical metabolites for tumor growth and undergo metabolic reprogramming to support glycolysis. However, the molecular mechanisms responsible for this change remain unclear. Here, we report that TGF-β1- or PDGF-induced CAFs switch from oxidative phosphorylation to aerobic glycolysis. We identify downregulation of isocitrate dehydrogenase 3α (IDH3α) as a marker for this switch. Furthermore, miR-424 downregulates IDH3α during CAF formation. Downregulation of IDH3α decreases the effective level of α-ketoglutarate (α-KG) by reducing the ratio of α-KG to fumarate and succinate, resulting in PHD2 inhibition and HIF-1α protein stabilization. The accumulation of HIF-1α, in turn, promotes glycolysis by increasing …

Identification Of A Family Of Fatty Acid-Speciated Sonic Hedgehog Proteins, Whose Members Display Differential Biological Properties, Jun Long, Robert Tokhunts, William M. Old, Stephane Houel, Jezabel Rodgriguez-Blanco, Samer Singh, Neal Schilling, Anthony J. Capobianco, Natalie G. Ahn, David J. Robbins

Dartmouth Scholarship

Hedgehog (HH) proteins are proteolytically processed into a biologically active form that is covalently modified by cholesterol and palmitate. However, most studies of HH biogenesis have characterized protein from cells in which HH is overexpressed. We purified Sonic Hedgehog (SHH) from cells expressing physiologically relevant levels and showed that it was more potent than SHH isolated from overexpressing cells. Furthermore, the SHH in our preparations was modified with a diverse spectrum of fatty acids on its amino termini, and this spectrum of fatty acids varied dramatically depending on the growth conditions of the cells. The fatty acid composition of SHH …

Overexpression Of Mir‑145 In U87 Cells Reduces Glioma Cell Malignant Phenotype And Promotes Survival After In Vivo Implantation, Yong Lu, Michael Chopp, Xuguang Zheng, Mark Katakowski, Ding Wang, Elise Fraser, Monique Nguyen, Feng Jiang

Neurology Articles

In the present study, we sought to elucidate the effect of miR‑145 on glioma cell progression and its mechanisms of action. We examined the effects of miR‑145 on proliferation and invasion of U87 glioma cells and on capillary tube formation. Our data show that restoration of miR‑145 in U87 glioma cells significantly reduced their in vitro proliferation, invasion and angiogenesis. However, decreased miR‑145 expression promoted U87 glioma cell proliferation, invasion and angiogenesis, and reduced-expression of miR‑145 increased ADAM17 and EGFR expression in U87 cells. Overexpression of miR‑145 reduced ADAM17 and EGFR expression. VEGF secretion and VEGF expression were decreased by …

Emerging Drugs For Sickle Cell Anemia., Priya C Singh, Samir K. Ballas

Cardeza Foundation for Hematologic Research

INTRODUCTION: The search for effective therapeutic interventions for sickle cell disease (SCD) has been an ongoing endeavor for over 50 years. During this period, only hydroxyurea (HU), which received US FDA approval in February 1998, was identified as an effective therapeutic agent in preventing or ameliorating the frequency of vaso-occlusive crises, acute chest syndrome and the need for blood transfusion. Approximately 25% of patients with sickle cell anemia (SCA), however, do not respond to HU and some patients experiencing serious side effects of this chemotherapeutic agent. Nevertheless, the success of HU opened the sluice gates to identify other effective drug …

Predicting Functional And Regulatory Divergence Of A Drug Resistance Transporter Gene In The Human Malaria Parasite, Geoffrey H. Siwo, Asako Tan, Katrina A. Button-Simons, Upeka Samarakoon, Lisa A. Checkley, Richard S. Pinapati, Michael T. Ferdig

Dartmouth Scholarship

Background:

The paradigm of resistance evolution to chemotherapeutic agents is that a key coding mutation in a specific gene drives resistance to a particular drug. In the case of resistance to the anti-malarial drug chloroquine (CQ), a specific mutation in the transporter pfcrt is associated with resistance. Here, we apply a series of analytical steps to gene expression data from our lab and leverage 3 independent datasets to identify pfcrt-interacting genes. Resulting networks provide insights into pfcrt’s biological functions and regulation, as well as the divergent phenotypic effects of its allelic variants in different genetic backgrounds.

Results:

Tumor Cell Targeting By Iron Oxide Nanoparticles Is Dominated By Different Factors In Vitro Versus In Vivo, Christian Ndong, Jennifer A. Tate, Warren C. Kett, Jaya Batra, Eugene Demidenko, Lionel D. Lewis, P. Jack Hoopes, Tillmann U. Gerngross, Karl E. Griswold

Dartmouth Scholarship

Realizing the full potential of iron oxide nanoparticles (IONP) for cancer diagnosis and therapy requires selective tumor cell accumulation. Here, we report a systematic analysis of two key determinants for IONP homing to human breast cancers: (i) particle size and (ii) active vs passive targeting. In vitro, molecular targeting to the HER2 receptor was the dominant factor driving cancer cell association. In contrast, size was found to be the key determinant of tumor accumulation in vivo, where molecular targeting increased tumor tissue concentrations for 30 nm but not 100 nm IONP. Similar to the in vitro results, PEGylation …

Novel Actions Of Next-Generation Taxanes Benefit Advanced Stages Of Prostate Cancer., Renée De Leeuw, Lisa D. Berman-Booty, Matthew J. Schiewer, Stephen J Ciment, Robert Den, Adam P. Dicker, William Kelly, Edouard J. Trabulsi, Costas D. Lallas, Leonard G. Gomella, Karen E. Knudsen

PURPOSE: To improve the outcomes of patients with castration-resistant prostate cancer (CRPC), there is an urgent need for more effective therapies and approaches that individualize specific treatments for patients with CRPC. These studies compared the novel taxane cabazitaxel with the previous generation docetaxel, and aimed to determine which tumors are most likely to respond.

EXPERIMENTAL DESIGN: Cabazitaxel and docetaxel were compared via in vitro modeling to determine the molecular mechanism, biochemical and cell biologic impact, and cell proliferation, which was further assessed ex vivo in human tumor explants. Isogenic pairs of RB knockdown and control cells were interrogated in vitro …

Diversification Of Importin-Α Isoforms In Cellular Trafficking And Disease States., Ruth A. Pumroy, Gino Cingolani

Department of Biochemistry and Molecular Biology Faculty Papers

The human genome encodes seven isoforms of importin α which are grouped into three subfamilies known as α1, α2 and α3. All isoforms share a fundamentally conserved architecture that consists of an N-terminal, autoinhibitory, importin-β-binding (IBB) domain and a C-terminal Arm (Armadillo)-core that associates with nuclear localization signal (NLS) cargoes. Despite striking similarity in amino acid sequence and 3D structure, importin-α isoforms display remarkable substrate specificity in vivo. In the present review, we look at key differences among importin-α isoforms and provide a comprehensive inventory of known viral and cellular cargoes that have been shown to associate preferentially with specific …

Amyloid Precursor-Like Protein 2 (Aplp2) Affects The Actin Cytoskeleton And Increases Pancreatic Cancer Growth And Metastasis., Poomy Pandey, Satyanarayana Rachagani, Srustidhar Das, Parthasarathy Seshacharyulu, Yuri Sheinin, Naava Naslavsky, Zenggang Pan, Brittney L.

Meza, Steve Caplan, Surinder K. Batra, Joyce C. Solheim

Journal Articles: Biochemistry & Molecular Biology

Amyloid precursor-like protein 2 (APLP2) is aberrantly expressed in pancreatic cancer. Here we showed that APLP2 is increased in pancreatic cancer metastases, particularly in metastatic lesions found in the diaphragm and intestine. Examination of matched human primary tumor-liver metastasis pairs showed that 38.1% of the patients had positive APLP2 expression in both the primary tumor and the corresponding liver metastasis. Stable knock-down of APLP2 expression (with inducible shRNA) in pancreatic cancer cells reduced the ability of these cells to migrate and invade. Loss of APLP2 decreased cortical actin and increased intracellular actin filaments in pancreatic cancer cells. Down-regulation of APLP2 …

Tsc2/Mtorc1 Signaling Controls Paneth And Goblet Cell Differentiation In The Intestinal Epithelium, Y. Zhou, Piotr G. Rychahou, Q. Wang, Heidi L. Weiss, B. Mark Evers

Markey Cancer Center Faculty Publications

The intestinal mucosa undergoes a continual process of proliferation, differentiation and apoptosis, which is regulated by multiple signaling pathways. Notch signaling is critical for the control of intestinal stem cell maintenance and differentiation. However, the precise mechanisms involved in the regulation of differentiation are not fully understood. Previously, we have shown that tuberous sclerosis 2 (TSC2) positively regulates the expression of the goblet cell differentiation marker, MUC2, in intestinal cells. Using transgenic mice constitutively expressing a dominant negative TSC2 allele, we observed that TSC2 inactivation increased mTORC1 and Notch activities, and altered differentiation throughout the intestinal epithelium, with a marked …

Vivien Thomas: Master Craftsman, Gifted Teacher, And Unsung Hero., Alisha Joyner, B.S., Charles J. Yeo, Md, Pinckney J. Maxwell, Iv, Md

Department of Surgery Gibbon Society Historical Profiles

The field of pediatric cardiovascular surgery gained international recognition in 1944 with the first successful correction of a tetralogy of Fallot congenital anomaly in a 15-month-old patient. Dr. Helen Taussig (1898 to 1986), a pediatrician at Johns Hopkins Hospital, recognized the need for the procedure. Dr. Alfred Blalock (1899 to 1964), Chief of Surgery at Johns Hopkins Hospital, is credited with performing the surgery. However, there is an unsung hero who for many years did not receive a single mention in the medical literature. Vivien Thomas (1910 to 1985) was Dr. Blalock’s research assistant who is said to have stood …

Designer Receptors Enhance Memory In A Mouse Model Of Down Syndrome, Ashley M. Fortress, Eric D. Hamlett, Elena M. Vazey, Gary Aston-Jones, Wayne A. Cass, Heather A. Boger, Ann-Charlotte E. Granholm

Neuroscience Faculty Publications

Designer receptors exclusively activated by designer drugs (DREADDs) are novel and powerful tools to investigate discrete neuronal populations in the brain. We have used DREADDs to stimulate degenerating neurons in a Down syndrome (DS) model, Ts65Dn mice. Individuals with DS develop Alzheimer's disease (AD) neuropathology and have elevated risk for dementia starting in their 30s and 40s. Individuals with DS often exhibit working memory deficits coupled with degeneration of the locus coeruleus (LC) norepinephrine (NE) neurons. It is thought that LC degeneration precedes other AD-related neuronal loss, and LC noradrenergic integrity is important for executive function, working memory, and attention. …

Microbiology, Immunology, and Molecular Genetics Faculty Publications

We previously reported the tumor suppressor function of Zinc-fingers and homeoboxes 2 (ZHX2) in hepatocellular carcinoma (HCC). Other studies indicate the association of increased ZHX2 expression with improved response to high dose chemotherapy in multiple myeloma. Here, we aim to test whether increased ZHX2 levels in HCC cells repress multidrug resistance 1(MDR1) expression resulting in increased sensitivity to chemotherapeutic drugs. We showed evidence that increased ZHX2 levels correlated with reduced MDR1 expression and enhanced the cytotoxicity of CDDP and ADM in different HCC cell lines. Consistently, elevated ZHX2 significantly reduced ADM efflux in HepG2 cells and greatly increased the CDDP-mediated …

A Case Of Cutaneous Larva Migrans Presenting In A Pregnant Patient., Kasie Kudrewicz, Kylee N Crittenden, Alison Himes

Women’s Health Articles

Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of animal hookworm larvae into the skin. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated owing to the patient's pregnancy. Cryotherapy with liquid nitrogen resulted in complete resolution of her lesion and symptoms.

Biomarkers Of Animal Health: Integrating Nutritional Ecology, Endocrine Ecophysiology, Ecoimmunology, And Geospatial Ecology, Robin Warne, Glenn Proudfoot, Erica Crespi

Publications

Diverse biomarkers including stable isotope, hormonal, and ecoimmunological assays are powerful tools to assess animal condition. However, an integrative approach is necessary to provide the context essential to understanding how biomarkers reveal animal health in varied ecological conditions. A barrier to such integration is a general lack of awareness of how shared extraction methods from across fields can provide material from the same animal tissues for diverse biomarker assays. In addition, the use of shared methods for extracting differing tissue fractions can also provide biomarkers for how animal health varies across time. Specifically, no study has explicitly illustrated the depth …

Current And Emerging Treatment Options For Anca-Associated Vasculitis: Potential Role Of Belimumab And Other Baff/April Targeting Agents, Aleksander Lenert, Petar Lenert

Internal Medicine Faculty Publications

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) comprises several clinical entities with diverse clinical presentations, outcomes, and nonunifying pathogenesis. AAV has a clear potential for relapses, and shows unpredictable response to treatment. Cyclophosphamide-based therapies have remained the hallmark of induction therapy protocols for more than four decades. Recently, B-cell depleting therapy with the anti-CD20 antibody rituximab has proved beneficial in AAV, leading to Food and Drug Administration approval of rituximab in combination with corticosteroids for the treatment of AAV in adults. Rituximab for ANCA-associated vasculitis and other clinical trials provided clear evidence that rituximab was not inferior to cyclophosphamide for remission …
