Tdp1-Independent Pathways In The Process And Repair Of Top1-Induced Dna Damage, Huimin Zhang, Yun Xiong, Dan Su, Chao Wang, Mrinal Srivastava, Mengfan Tang, Xu Feng, Min Huang, Zhen Chen, Junjie Chen

Faculty, Staff and Student Publications

Anticancer drugs, such as camptothecin (CPT), trap topoisomerase I (TOP1) on DNA and form TOP1 cleavage complexes (TOP1cc). Alternative repair pathways have been suggested in the repair of TOP1cc. However, how these pathways work with TDP1, a key repair enzyme that specifically hydrolyze the covalent bond between TOP1 catalytic tyrosine and the 3'-end of DNA and contribute to the repair of TOP1cc is poorly understood. Here, using unbiased whole-genome CRISPR screens and generation of co-deficient cells with TDP1 and other genes, we demonstrate that MUS81 is an important factor that mediates the generation of excess double-strand breaks (DSBs) in TDP1 …

Faculty, Staff and Student Publications

BACKGROUND: Chronic kidney disease (CKD) is characterized by increased myocardial mass despite near-normal blood pressure, suggesting the presence of a separate trigger. A potential driver is SIRPα (signal regulatory protein alpha)-a mediator impairing insulin signaling. The objective of this study is to assess the role of circulating SIRPα in CKD-induced adverse cardiac remodeling.

METHODS: SIRPα expression was evaluated in mouse models and patients with CKD. Specifically, mutant, muscle-specific, or cardiac muscle-specific SIRPα KO (knockout) mice were examined after subtotal nephrectomy. Cardiac function was assessed by echocardiography. Metabolic responses were confirmed in cultured muscle cells or cardiomyocytes.

RESULTS: We demonstrate that …

Myt1l In The Making: Emerging Insights On Functions Of A Neurodevelopmental Disorder Gene, Jiayang Chen, Allen Yen, Colin P Florian, Joseph D Dougherty

2020-Current year OA Pubs

Large scale human genetic studies have shown that loss of function (LoF) mutations in MYT1L are implicated in neurodevelopmental disorders (NDDs). Here, we provide an overview of the growing number of published MYT1L patient cases, and summarize prior studies in cells, zebrafish, and mice, both to understand MYT1L's molecular and cellular role during brain development and consider how its dysfunction can lead to NDDs. We integrate the conclusions from these studies and highlight conflicting findings to reassess the current model of the role of MYT1L as a transcriptional activator and/or repressor based on the biological context. Finally, we highlight additional …

Electro-Mechanical Coupling Of Kcnq Channels Is A Target Of Epilepsy-Associated Mutations And Retigabine, Nien-Du Yang, Richard Kanyo, Lu Zhao, Jingru Li, Po Wei Kang, Alex Kelly Dou, Kelli Mcfarland White, Jingyi Shi, Jeanne M Nerbonne, Harley T Kurata, Jianmin Cui

2020-Current year OA Pubs

KCNQ2 and KCNQ3 form the M-channels that are important in regulating neuronal excitability. Inherited mutations that alter voltage-dependent gating of M-channels are associated with neonatal epilepsy. In the homolog KCNQ1 channel, two steps of voltage sensor activation lead to two functionally distinct open states, the intermediate-open (IO) and activated-open (AO), which define the gating, physiological, and pharmacological properties of KCNQ1. However, whether the M-channel shares the same mechanism is unclear. Here, we show that KCNQ2 and KCNQ3 feature only a single conductive AO state but with a conserved mechanism for the electro-mechanical (E-M) coupling between voltage sensor activation and pore …

Comparing Statistical Methods In Assessing The Prognostic Effect Of Biomarker Variability On Time-To-Event Clinical Outcomes, Feng Gao, Jingqin Luo, Jingxia Liu, Fei Wan, Guoqiao Wang, Mae Gordon, Chengjie Xiong

2020-Current year OA Pubs

BACKGROUND: In recent years there is increasing interest in modeling the effect of early longitudinal biomarker data on future time-to-event or other outcomes. Sometimes investigators are also interested in knowing whether the variability of biomarkers is independently predictive of clinical outcomes. This question in most applications is addressed via a two-stage approach where summary statistics such as variance are calculated in the first stage and then used in models as covariates to predict clinical outcome in the second stage. The objective of this study is to compare the relative performance of various methods in estimating the effect of biomarker variability. …

The Virtual Peripheral Nerve Academy: Education For The Identification And Treatment Of Peripheral Nerve Disorders, Erica B. Lee, Allison Podsednik, Kimberly Khoo, Amal Cheema, Raysa Cabrejo, Chen Shen, Joseph Rosen, A Lee Dellon

School of Medicine Publications

Millions of people around the globe suffer peripheral nerve injuries caused by trauma and medical disorders. However, medical school curricula are profoundly deficient in peripheral nerve education. This lack of knowledge within the healthcare profession may cause inadequate patient care. We developed the Virtual Peripheral Nerve Academy (VPNA) as a reusable virtual learning environment to provide medical students with detailed education on the peripheral nervous system (PNS). Students are introduced to the PNS through virtual 3D rendering of the human body, wherein they visualize individual nerves through dissection and observe normal motor and sensory function associated with each nerve. PNS …

Urinary Matrix Gla Protein Is Associated With Mortality Risk In Flemish Population: A Prospective Study, Dongmei Wei, Jesus D. Melgarejo, Thomas Vanassche, Lucas Van Aelst, Stefan Janssens, Peter Verhamme, Zhen-Yu Zhang

School of Medicine Publications

Background: Vascular calcification is strongly related to the risk of mortality and cardiovascular (CV) diseases. In vascular calcification, matrix Gla protein (MGP), a small vitamin K-dependent protein, is an important mineralization inhibitor. Recent studies showed that circulating MGP is associated with mortality risk. However, the longitudinal association between urinary excretion of MGP and all-cause mortality was not established.

Materials and methods: Urinary MGP was measured in 776 randomly recruited Flemish population (mean age: 51.2 years; 50.9% women) at baseline (during 2005–2010) using capillary electrophoresis coupled with mass spectrometry. Plasma inactive MGP [desphospho-uncarboxylated MGP (dp-ucMGP)] levels were quantified in 646 individuals …

Faculty Research 2022

Osteosarcoma is a primary malignant bone tumor arising from bone-forming mesenchymal cells in children and adolescents. Despite efforts to understand the biology of the disease and identify novel therapeutics, the survival of osteosarcoma patients remains dismal. We have concurrently profiled the copy number and gene expression of 226 osteosarcoma samples as part of the Strategic Partnering to Evaluate Cancer Signatures (SPECS) initiative. Our results demonstrate the heterogeneous landscape of osteosarcoma in younger populations by showing the presence of genome-wide copy number abnormalities occurring both recurrently among samples and in a high frequency. Insulin growth factor receptor 1 (IGF1R) is a …

The Effect Of Transfer Of Care Protocol On The Rehospitalization Rates In Psychiatric Patients, Fernando Guillen Msn, Cnp, Pmhnp-Bc

Exploration Of Vaccination Attitudes Among Parents And Caregivers In A Rural Appalachian Health Clinic, Radwa Omar, Karen Hande, Natasha Mcclure

Journal of Appalachian Health

At a rural Appalachian health clinic in Kentucky, 20% of patients under 18 years were not up to date with the CDC-recommended immunization schedule. Reasons parents or caregivers chose to delay or refuse their child’s immunizations were explored using the Caregiver Vaccination Attitude Scale. High levels of trust in the healthcare provider and self-reported vaccine knowledge highlight opportunities for rural healthcare providers to apply evidence-based communication strategies to address vaccine hesitancy and promote the safety and health of the entire community.

Analyzing The Relationship Between Non-Pharmacologic Interventions And Pregnancy-Induced Hypertension: An Integrative Review, Karen Ann Ellis

Doctoral Dissertations and Projects

Maternal and fetal health outcomes are threatened due to pregnancy-induced hypertension, which complicates nearly 6%–10% of pregnancies worldwide. This disease carries a high risk of maternal and fetal morbidity and mortality. Medications are commonly used to reduce blood pressure and physical consequences related to high blood pressure. However, the use of medications does not resolve the disease as there is no pharmacological cure. Current evidence demonstrates the detrimental long-term effects of pregnancy-induced hypertension and the increased risk of future cardiac disease. Close surveillance and effective treatment during pregnancy is needed to prevent serious complications. The aim of this integrative review …

The Importance Of Education In The Management Of Diabetes, Taylor Nicole Henry

Doctoral Dissertations and Projects

Type 2 diabetes continues to affect millions of people every day across the United States. Uncontrolled blood sugars pose a risk to individuals’ overall health by causing microvascular and macrovascular changes and ultimately lead to an earlier mortality. One’s blood sugar levels can be checked at any time, but an individual’s hemoglobin (hgb) A1c is a three-month average that allows the diabetic to have an overview on how they are managing their diabetes. Appropriate nutrition and having someone hold the diabetic accountable have proven to limit these risks by lowering the patient’s hgb A1c. Providers and staff need to do …
