Editorial: Controversies In The Local Management Of Lung Cancer, John M. Varlotto, Giulia Veronesi

Open Access Articles

At the time we agreed to edit this special edition of Frontiers in early 2017, the immunotherapy revolution was already established in the second-line treatment of metastatic non-small cell lung cancer (NSCLC) and even to a select group of patients (those whose tumor cells expressed PD-L1 of ≥50%) in the first-line treatment of metastatic disease. We felt that the summarization and understanding of the strengths and benefits of our local modalities were needed prior to the possible integration of immunotherapy into the treatment paradigms of Stages I–III NSCLC and small cell lung cancer (SCLC).


A Rationally Engineered Capsid Variant Of Aav9 For Systemic Cns-Directed And Peripheral Tissue-Detargeted Gene Delivery In Neonates, Dan Wang, Shaoyong Li, Dominic J.

Adeno-associated virus (AAV) has provided the gene therapy field with the most powerful in vivo gene delivery vector to realize safe, efficacious, and sustainable therapeutic gene expression. Because many clinically relevant properties of AAV-based vectors are governed by the capsid, much research effort has been devoted to the development of AAV capsids for desired features. Here, we combine AAV capsid discovery from nature and rational engineering to report an AAV9 capsid variant, designated as AAV9.HR, which retains AAV9's capability to traverse the blood-brain barrier and transduce neurons. This variant shows reduced transduction in peripheral tissues when delivered through ...

Tai, Jun Xie, Kaiyuen Fong, Matthew Seetin, Cheryl Heiner, Qin Su, Michael Weiand, Daniella Wilmot, Maria L. Zapp, Guangping Gao 2018 University of Massachusetts Medical School

Adeno-Associated Virus Genome Population Sequencing Achieves Full Vector Genome Resolution And Reveals Human-Vector Chimeras, Phillip W. L. Tai, Jun Xie, Kaiyuen Fong, Matthew Seetin, Cheryl Heiner, Qin Su, Michael Weiand, Daniella Wilmot, Maria L. Zapp, Guangping Gao

Open Access Articles

Recombinant adeno-associated virus (rAAV)-based gene therapy has entered a phase of clinical translation and commercialization. Despite this progress, vector integrity following production is often overlooked. Compromised vectors may negatively impact therapeutic efficacy and safety. Using single molecule, real-time (SMRT) sequencing, we can comprehensively profile packaged genomes as a single intact molecule and directly assess vector integrity without extensive preparation. We have exploited this methodology to profile all heterogeneic populations of self-complementary AAV genomes via bioinformatics pipelines and have coined this approach AAV-genome population sequencing (AAV-GPseq). The approach can reveal the relative distribution of truncated genomes versus full-length genomes in ...

Open Access Articles

Cancer immunotherapy has been revolutionised by drugs that enhance the ability of the immune system to detect and fight tumors. Immune checkpoint therapies that target the programmed death-1 receptor (PD-1), or its ligand (PD-L1) have shown unprecedented rates of durable clinical responses in patients with various cancer types. However, there is still a large fraction of patients that do not respond to checkpoint inhibitors, and the challenge remains to find cellular and molecular cues that could predict which patients would benefit from these therapies. Using a series of qualitative and quantitative methods we show here that PBMCs and platelets from ...


A Fresh Look At Huntingtin Mrna Processing In Huntington's Disease, Lindsay S. Romo, Emily S. Mohn, Neil Aronin 2018 University of Massachusetts Medical School

A Fresh Look At Huntingtin Mrna Processing In Huntington's Disease, Lindsay S. Romo, Emily S. Mohn, Neil Aronin

RNA Therapeutics Institute Publications

Huntington's disease (HD) is an inherited neurodegenerative disorder caused by a mutation that expands the polyglutamine (CAG) repeat in exon 1 of the huntingtin (HTT) gene. Wild-type HTT protein interacts with other proteins to protect cells against toxic stimuli, mediate vesicle transport and endocytosis, and modulate synaptic activity. Mutant HTT protein disrupts autophagy, vesicle transport, neurotransmitter signaling, and mitochondrial function. Although many of the activities of wild-type HTT protein and the toxicities of mutant HTT protein are characterized, less is known about the activities of HTT mRNA. Most putative HD therapies aim to target mutant HTT mRNA before it ...

Cognitive And Emotional Correlates Of Improved Gait Distance During The Course Of Physical Therapy Treatment For An Incomplete Spinal Cord Injury, Danielle Miller

Honors Theses

Objective

The focus of spinal cord injury rehabilitation over the past four decades has shifted from medical management to issuses that affect quality of life and community participation (Gómara- Toldrà, Sliwinski, & Dijkers, 2014). However, the care team for spinal cord injury patients still need to collaberate in order to design and implement interventions that result in maximum participation to provide an individual with a spinal cord injury an effective rehabilitation program. In order to create such a rehablitation program, the care team must know how certain psychological and cognitive aspects, such as depression and implict memory, are related to the ...

In Vivo And In Vitro Studies Of Cry5b And Nicotinic Acetylcholine Receptor Agonist Anthelmintics Reveal A Powerful And Unique Combination Therapy Against Intestinal Nematode Parasites, Yan Hu, Melanie Miller, Bo Zhang, Thanh-Thanh Nguyen, Martin K. Nielsen, Raffi V. Aroian

Open Access Articles

BACKGROUND: The soil-transmitted nematodes (STNs) or helminths (hookworms, whipworms, large roundworms) infect the intestines of ~1.5 billion of the poorest peoples and are leading causes of morbidity worldwide. Only one class of anthelmintic or anti-nematode drugs, the benzimidazoles, is currently used in mass drug administrations, which is a dangerous situation. New anti-nematode drugs are urgently needed. Bacillus thuringiensis crystal protein Cry5B is a powerful, promising new candidate. Drug combinations, when properly made, are ideal for treating infectious diseases. Although there are some clinical trials using drug combinations against STNs, little quantitative and systemic work has been performed to define ...

Structure Determination Of A Bioengineered Human/Porcine Factor Viii For Hemophilia A Treatment, And Improvements To The Human Factor Viii Model, Ian Smith 2018 Western Washington University

Structure Determination Of A Bioengineered Human/Porcine Factor Viii For Hemophilia A Treatment, And Improvements To The Human Factor Viii Model, Ian Smith

Graduate Student Symposium

Blood coagulation factor VIII (FVIII), is a non-enzymatic cofactor which plays a crucial role in the formation of a stable blood clot. Absence or deficiency of FVIII results in the blood disorder hemophilia A; with symptoms including internal hemorrhaging and the inability to stop bleeding from open wounds. Treatment of hemophilia A relies on infusions of blood, plasma, or protein concentrates to replace FVIII. Unfortunately, approximately 30% of patients receiving replacement FVIII generate pathologic anti-FVIII inhibitory antibodies, which both reduce the effectiveness of the FVIII therapeutic and increase the severity of hemophilia A symptoms. We have determined the molecular structure ...


Spectral Properties Of Doxorubicin Doped Rhdl Nanoparticles, Sunil Shah 2018 University of North Texas Health Science Center at Fort Worth

Spectral Properties Of Doxorubicin Doped Rhdl Nanoparticles, Sunil Shah

Theses and Dissertations

Doxorubicin, also known as Adriamycin, is an anthracycline antibiotic which first gained clinical prominence in the early 1970’s as an effective antitumor agent. It is still used today to treat a spectrum of cancers like lymphoma, bladder, stomach, lung, breast, ovarian, and several others. Due to its production of free radicals to attack tumor cells, Doxorubicin interferes with mitochondrial phosphorylation and also induces cardiotoxicity. Thus, efficient and biocompatible delivery methods are needed for targeted drug delivery to overcome systemic toxicity. To maintain a high level of growth, tumor cells overexpress Scavenger receptors type B-1 (SR-B1). This cellular characteristic can ...


Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins 2018 University of Tennessee Health Science Center

Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or aseptic loosening of the implant components necessitating revision of the index procedure. The understanding of the exact etiology of these suboptimal outcomes of primary TKA is in its infancy. In order to elucidate the etiology of failure in primary TKAs, a baseline for the factors contributing to arthroplasty failure and dissatisfaction must first be established. The purpose of this study was ...


The Dancing Nurse: Addressing Barriers To The Implementation Of Movement-Based Interventions In Holistic Patient Care, Jessica Collier, Audrey Thompson PhD 2018 Oral Roberts University

The Dancing Nurse: Addressing Barriers To The Implementation Of Movement-Based Interventions In Holistic Patient Care, Jessica Collier, Audrey Thompson Phd

Nursing Undergraduate Work

The efficacy of dance movement therapy (DMT) is well demonstrated in contemporary nursing literature; however, implementation by healthcare professionals is often limited. Dance movement therapy was pioneered in the mid-20th century by classically trained modern dancer Marian Chace. Recent trends toward patient-centered care and interdisciplinary approaches render therapies such as DMT important modalities which nurses and other healthcare providers may become familiar with. This systematic research review focused on answering the question: “what are hindrances perceived by members of the healthcare team to implementing DMT as an alternative treatment modality?” Two variables were identified for the purposes of this ...


The Systemic Quantification Of Immune Cell Populations In Various Murine Models: How Age, Tumor Burden, And Immunotherapy Affect The Immune Response, Kavita Sinha 2018 University of Connecticut

The Systemic Quantification Of Immune Cell Populations In Various Murine Models: How Age, Tumor Burden, And Immunotherapy Affect The Immune Response, Kavita Sinha

Honors Scholar Theses

Immunotherapy as a form of cancer treatment has become increasingly popular in the past few decades. Researchers have worked to figure out how to best use the body’s natural defense mechanism, the immune system, to fight off and destroy cancer cells. In particular, the goal has been to manipulate checkpoint blockades such as CTLA-4 and PD-1 in order to take the breaks off of the immune system, allowing for a prolonged immune response to the cancer. This work has led to the development of human versions of anti-CTLA4 antibodies (ipilimumab, tremelimumab) and anti-PD1 antibodies (pembrolizumab and Nivolumab) that are ...


Maturation Of Human Induced Pluripotent Stem Cell Derived Engineered Cardiac Tissues Using Chief Transfection And Chronic Optical Pacing., Marc M. Dwenger 2018 University of Louisville

Maturation Of Human Induced Pluripotent Stem Cell Derived Engineered Cardiac Tissues Using Chief Transfection And Chronic Optical Pacing., Marc M. Dwenger

Electronic Theses and Dissertations

The immaturity of engineered cardiac tissues (ECTs) limits their ability to regenerate damaged myocardium and to serve as in vitro disease models and surrogates for drug toxicity testing. Several chronic biomimetic conditioning protocols, including mechanical stretch, perfusion, and electrical stimulation promote ECT maturation but have significant technical limitations. Non-contacting chronic light stimulation using heterologously expressed light-sensitive ChIEF ion channels, termed optogenetics, may be an advantageous alternative to chronic electrical stimulation. As a proof of principle, we transfected ECTs using an AAV packaged ChIEF and then verified acute optical pacing (OP) by patch clamp. We then chronically OP ECTs for 7 ...


Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, Charis L. Himeda, Takako I. Jones, Ching-Man A. Virbasius, Lihua Julie Zhu, Michael R. Green, Peter L. Jones 2018 University of Massachusetts Medical School

Identification Of Epigenetic Regulators Of Dux4-Fl For Targeted Therapy Of Facioscapulohumeral Muscular Dystrophy, Charis L. Himeda, Takako I. Jones, Ching-Man A. Virbasius, Lihua Julie Zhu, Michael R. Green, Peter L. Jones

Open Access Articles

Facioscapulohumeral muscular dystrophy (FSHD) is caused by epigenetic de-repression of the disease locus, leading to pathogenic misexpression of the DUX4 gene in skeletal muscle. While the factors and pathways involved in normal repression of the FSHD locus in healthy cells have been well characterized, very little is known about those responsible for the aberrant activation of DUX4-fl in FSHD myocytes. Reasoning that DUX4-fl activators might represent useful targets for small molecule inhibition, we performed a highly targeted, candidate-based screen of epigenetic regulators in primary FSHD myocytes. We confirmed several of the strongest and most specific candidates (ASH1L, BRD2, KDM4C, and ...

The United States and selected South American countries have starkly different economic, social, and political backgrounds which impact the way in which physical therapy is administered and received. This allows for comparisons to be made between each respective model of physical therapy, creating a running dialog on how these programs can improve and ...


Bb-Cl-Amidine As A Novel Therapeutic For Canine And Feline Mammary Cancer Via Activation Of The Endoplasmic Reticulum Stress Pathway, Melissa M. Ledet, Robyn Anderson, Rebecca Harman, Aaron Muth, Paul R. Thompson, Scott A. Coonrod, Gerlinde R. Van de Walle 2018 Cornell University

Bb-Cl-Amidine As A Novel Therapeutic For Canine And Feline Mammary Cancer Via Activation Of The Endoplasmic Reticulum Stress Pathway, Melissa M. Ledet, Robyn Anderson, Rebecca Harman, Aaron Muth, Paul R. Thompson, Scott A. Coonrod, Gerlinde R. Van De Walle

Open Access Articles

BACKGROUND: Mammary cancer is highly prevalent in dogs and cats and results in a poor prognosis due to critically lacking viable treatment options. Recent human and mouse studies have suggested that inhibiting peptidyl arginine deiminase enzymes (PAD) may be a novel breast cancer therapy. Based on the similarities between human breast cancer and mammary cancer in dogs and cats, we hypothesized that PAD inhibitors would also be an effective treatment for mammary cancer in these animals.

METHODS: Canine and feline mammary cancer cell lines were treated with BB-Cl-Amidine (BB-CLA) and evaluated for viability and tumorigenicity. Endoplasmic reticulum stress was tested ...

Towards An Arthritis Flare-Responsive Drug Delivery System, Nitin Joshi, Ellen M. Gravallese, Joerg Ermann, Jeffrey M. Karp

Open Access Articles

Local delivery of therapeutics for the treatment of inflammatory arthritis (IA) is limited by short intra-articular half-lives. Since IA severity often fluctuates over time, a local drug delivery method that titrates drug release to arthritis activity would represent an attractive paradigm in IA therapy. Here we report the development of a hydrogel platform that exhibits disassembly and drug release controlled by the concentration of enzymes expressed during arthritis flares. In vitro, hydrogel loaded with triamcinolone acetonide (TA) releases drug on-demand upon exposure to enzymes or synovial fluid from patients with rheumatoid arthritis. In arthritic mice, hydrogel loaded with a fluorescent ...
