Here we provide protocols for implementing Seurat and Giotto packages to elucidate cell-type distribution in our example human ureter scRNA-seq dataset. We also describe how to create a stand-alone interactive web application using Seurat libraries to visualize and share our results. For complete details on the use and execution of this protocol, please refer to Fink et al. (2022).

Influence Of Canonical And Non-Canonical Ifnlr1 Isoform Expression On Interferon Lambda Signaling, John Evans

MUSC Theses and Dissertations

Interferon lambdas (IFNLs) are innate immune cytokines that induce antiviral cellular responses by signaling through a heterodimer composed of IL10RB and the interferon lambda receptor 1 (IFNLR1). Multiple IFNLR1 transcriptional variants are expressed in vivo and are predicted to encode distinct protein isoforms whose function is not fully established. IFNLR1 isoform 1 has the highest relative transcriptional expression and encodes the full-length functional form that supports canonical IFNL signaling. IFNLR1 isoforms 2 and 3 have lower relative expression and are predicted to encode signaling defective proteins. To gain insight into IFNLR1 function and regulation, we explored how altering relative expression …

Department of Radiology Faculty Papers

Introduction: Circulating tumor-derived biomarkers can potentially impact cancer management throughout the continuum of care. This small exploratory study aimed to assess the relative levels of such biomarkers in the tumor-draining vascular beds in patients with solid tumors compared to levels in their peripheral veins.

Methods: Using an endovascular image-guided approach, we obtained blood samples from peripheral veins and other vascular compartments–including the most proximal venous drainage from solid tumors–from a set of nine oncology patients with various primary and metastatic malignancies. We then interrogated these samples for a panel of oncological biomarkers, including circulating tumor cells (CTCs), exosome-derived microRNAs (miRNAs), …

A Mast Cell-Thermoregulatory Neuron Circuit Axis Regulates Hypothermia In Anaphylaxis, Chunjing Bao, Ouyang Chen, Huaxin Sheng, Jeffrey Zhang, Yikai Luo, Byron W Hayes, Han Liang, Wolfgang Liedtke, Ru-Rong Ji, Soman N Abraham

Faculty, Staff and Student Publications

IgE-mediated anaphylaxis is an acute life-threatening systemic reaction to allergens, including certain foods and venoms. Anaphylaxis is triggered when blood-borne allergens activate IgE-bound perivascular mast cells (MCs) throughout the body, causing an extensive systemic release of MC mediators. Through precipitating vasodilatation and vascular leakage, these mediators are believed to trigger a sharp drop in blood pressure in humans and in core body temperature in animals. We report that the IgE/MC-mediated drop in body temperature in mice associated with anaphylaxis also requires the body's thermoregulatory neural circuit. This circuit is activated when granule-borne chymase from MCs is deposited on proximal TRPV1+ …

Faculty, Staff and Student Publications

Background: Prognostic scores that can identify patients at risk for early death are needed to aid treatment decision-making and patient selection for clinical trials. We compared the accuracy of four scores to predict early death (within 90 days) and overall survival (OS) in patients with metastatic gastric and esophageal (GE) cancer.

Methods: Advanced GE cancer patients receiving first-line systemic therapy were included. Prognostic risks were calculated using: Royal Marsden Hospital (RMH), MD Anderson Cancer Centre (MDACC), Gustave Roussy Immune (GRIm-Score), and MD Anderson Immune Checkpoint Inhibitor (MDA-ICI) scores. Overall survival (OS) was estimated using the Kaplan-Meier method. Cox proportional hazards …

A New Era Of Morphological Investigations: Reviewing Methods For Comparative Anatomical Studies, K. L. Ford, J. S. Albert, A. P. Summers, B. P. Hedrick, E. R. Schachner, A. S. Jones, K. Evans, P. Chakrabarty

School of Medicine Faculty Publications

The increased use of imaging technology in biological research has drastically altered morphological studies in recent decades and allowed for the preservation of important collection specimens alongside detailed visualization of bony and soft-tissue structures. Despite the benefits associated with these newer imaging techniques, there remains a need for more "tra- ditional"methods of morphological examination in many comparative studies. In this paper, we describe the costs and benefits of the various methods of visualizing, examining, and comparing morphological structures. There are significant differences not only in the costs associated with these different methods (monetary, time, equipment, and software), but also in …

Apkcs Role In Neuroblastoma Cell Signaling Cascades And Implications Of Apkcs Inhibitors As Potential Therapeutics, Sloan Breedy

USF Tampa Graduate Theses and Dissertations

Neuroblastoma (NB) is a cancer that develops in the neuroblasts. It is the most common cancer in children under the age of 1 year, accounting for approximately 6% of all cancers. The prognosis of NB is linked to both age and degree of cell differentiation. This results in a range of survival rates for patients, with outcomes ranging from recurrence and mortality to high survival rates and tumor regression. Our previous work indicated that PKC-ι promotes cell proliferation in NB cells through the PKC-ι/Cdk7/Cdk2 cascade. We report on two atypical protein kinase inhibitors as potential therapeutic candidates against BE(2)-C and …

Faculty, Staff and Student Publications

The placenta is one of the most important yet least understood organs. Due to the limitations of conventional research approaches, we are still far from a comprehensive understanding of mouse placentation, especially regarding the differentiation of trophoblast lineages at the early developmental stage. To decipher cell compositions and developmental processes, we systematically profile the single-cell transcriptomes of trophoblast cells from extraembryonic tissues (embryonic day 7.5 (E7.5) and E8.5) and placentae (E9.5-E14.5) at one-day intervals. We identify distinct trophoblast cell types during mouse placentation, including unreported progenitor cells and intermediate precursor cells. An updated differentiation roadmap of mouse trophoblast lineages is …

Cyanobacteria And Algal-Based Biological Life Support System (Blss) And Planetary Surface Atmospheric Revitalizing Bioreactor Brief Concept Review, Ryan Keller, Karthik Goli, William Porter, Aly Alrabaa, Jeffrey A Jones

Faculty, Staff and Students Publications

Exploring austere environments required a reimagining of resource acquisition and utilization. Cyanobacterial in situ resources utilization (ISRU) and biological life support system (BLSS) bioreactors have been proposed to allow crewed space missions to extend beyond the temporal boundaries that current vehicle mass capacities allow. Many cyanobacteria and other microscopic organisms evolved during a period of Earth's history that was marked by very harsh conditions, requiring robust biochemical systems to ensure survival. Some species work wonderfully in a bioweathering capacity (siderophilic), and others are widely used for their nutritional power (non-siderophilic). Playing to each of their strengths and having them grow …

Random Forest Model Reveals The Interaction Between N6-Methyladenosine Modifications And Rna-Binding Proteins, Wei Hong, Yanding Zhao, Yi-Lan Weng, Chao Cheng

Faculty, Staff and Students Publications

RNA-binding proteins (RBPs) have critical roles in N6-methyladenosine (m6A) modification process. We designed a Random Forest (RF) model to systematically analyze the interaction among RBPs and m6A modifications by integrating the binding signals from hundreds of RBPs. Accurate prediction of m6A sites demonstrated significant connections between RBP bindings and m6A modifications. The relative importance of different RBPs from the model provided a quantitative metric to evaluate their interactions with m6A modifications. Redundancy analysis showed that several RBPs may have similar binding patterns with m6A sites. The RF model exhibited fairly high prediction accuracy across cell lines, suggesting a conservative RBP …

Hervs And Cancer-A Comprehensive Review Of The Relationship Of Human Endogenous Retroviruses And Human Cancers, Erik Stricker, Erin C Peckham-Gregory, Michael E Scheurer

Center for Medical Ethics and Health Policy Staff Publications

Genomic instability and genetic mutations can lead to exhibition of several cancer hallmarks in affected cells such as sustained proliferative signaling, evasion of growth suppression, activated invasion, deregulation of cellular energetics, and avoidance of immune destruction. Similar biological changes have been observed to be a result of pathogenic viruses and, in some cases, have been linked to virus-induced cancers. Human endogenous retroviruses (HERVs), once external pathogens, now occupy more than 8% of the human genome, representing the merge of genomic and external factors. In this review, we outline all reported effects of HERVs on cancer development and discuss the HERV …

Comparison Of Efficacy And Inflammatory Response To Thermoconjunctivoplasty Performed With Cautery Or Pulsed 1460 Nm Laser, Rodrigo Guimaraes De Souza, David Huang, Scott Prahl, Lauren Nakhleh, Stephen C Pflugfelder

Faculty, Staff and Students Publications

Conjunctivochalasis is a degenerative condition of the conjunctiva that disrupts tear distribution and causes irritation. Thermoreduction of the redundant conjunctiva is required if symptoms are not relieved with medical therapy. Near-infrared laser treatment is a more controlled method to shrink the conjunctiva than thermocautery. This study compared tissue shrinkage, histology, and postoperative inflammation in thermoconjunctivoplasty performed on the mouse conjunctiva using either thermocautery or pulsed 1460 nm near-infrared laser irradiation. Three sets of experiments were performed on female C57BL/6J mice (

Gemc1 And Mcidas Interactions With Swi/Snf Complexes Regulate The Multiciliated Cell-Specific Transcriptional Program, Michael Lewis, Tao Cheng, Moe R Mahjoub, Et Al.

2020-Current year OA Pubs

Multiciliated cells (MCCs) project dozens to hundreds of motile cilia from their apical surface to promote the movement of fluids or gametes in the mammalian brain, airway or reproductive organs. Differentiation of MCCs requires the sequential action of the Geminin family transcriptional activators, GEMC1 and MCIDAS, that both interact with E2F4/5-DP1. How these factors activate transcription and the extent to which they play redundant functions remains poorly understood. Here, we demonstrate that the transcriptional targets and proximal proteomes of GEMC1 and MCIDAS are highly similar. However, we identified distinct interactions with SWI/SNF subcomplexes; GEMC1 interacts primarily with the ARID1A containing …

Targeted Delivery Of Therapeutic Agents To The Mouse Brain Using A Stereotactic-Guided Focused Ultrasound Device, Zhongtao Hu, Yaoheng Yang, Dezhuang Ye, Si Chen, Yan Gong, Chinwendu Chukwu, Hong Chen

2020-Current year OA Pubs

Existing protocols of focused ultrasound (FUS) combined with microbubble-mediated blood-brain barrier (BBB) opening (FUS-BBBO) in preclinical research require expensive ultrasound equipment and complex operating procedures. We developed a low-cost, easy-to-use, and precise FUS device for small animal models in preclinical research. Here, we provide a detailed protocol for building the FUS transducer, attaching the transducer to a stereotactic frame for precise brain targeting, applying the integrated FUS device to perform FUS-BBBO in mice, and evaluating the FUS-BBBO outcome. For complete details on the use and execution of this protocol, please refer to Hu et al. (2022).

Imaging Of Brain Structural And Functional Effects In People With Human Immunodeficiency Virus, Erin E O'Connor, Edith V Sullivan, Linda Chang, Dima A Hammoud, Tony W Wilson, Ann B Ragin, Christina S Meade, Jennifer Coughlin, Beau M Ances

2020-Current year OA Pubs

Before the introduction of antiretroviral therapy, human immunodeficiency virus (HIV) infection was often accompanied by central nervous system (CNS) opportunistic infections and HIV encephalopathy marked by profound structural and functional alterations detectable with neuroimaging. Treatment with antiretroviral therapy nearly eliminated CNS opportunistic infections, while neuropsychiatric impairment and peripheral nerve and organ damage have persisted among virally suppressed people with HIV (PWH), suggesting ongoing brain injury. Neuroimaging research must use methods sensitive for detecting subtle HIV-associated brain structural and functional abnormalities, while allowing for adjustments for potential confounders, such as age, sex, substance use, hepatitis C coinfection, cardiovascular risk, and others. …

Standing In The Gap: The Academic And Professional Divide Between Health Administration And Health Policy, Steven W. Howard, Michael A. Counte, Leah J. Vriesman, Harrison D. Brink

APC Fund

There are diverse types of health care systems, policies and health care organizations existing in health care delivery arrangements across the world (1). Two distinct influential groups of professionals have emerged as a result. They are: 1. Macro-level, population-oriented heath policy planners and analysts (health policy professionals–HPP) and 2. More micro-level, institutionally-oriented managers and organizational leaders and executives (health management professionals–HMP). As the old idiom goes, “one can't see the forest for the trees.” Are HPP professionals at such “altitude” that they have a clear vision of the forest, but fail to understand how things are on the …

Narrative Review: The Fda’S Perfunctory Approach Of Dietary Supplement Regulations Giving Rise To Copious Reports Of Adverse Events, Weiqi Li, Albert Wertheimer

HPD Articles

Background: The Food and Drug Administration (FDA) originated from the passage of the 1906 Pure Food and Drugs act aimed to rein in the long-standing abuse in the consumer product marketplace. The act was passed to prohibit interstate commerce of misbranded and adulterated foods, drinks, drugs. Thus, promoting the FDA’s mission to protect the public health by regulating human and veterinary drugs, biological products, medical devices, food supply, cosmetics, and tobacco to ensure safety, efficacy, and security. Progressing further in 1994, the Dietary Supplement Health and Education Act (DSHEA) was established designating specific label requirements, providing regulatory framework, and authorizing …
