IL17 is required for the initiation and progression of pancreatic cancer, particularly in the context of inflammation, as previously shown by genetic and pharmacological approaches. However, the cellular compartment and downstream molecular mediators of IL17-mediated pancreatic tumorigenesis have not been fully identified. This study examined the cellular compartment required by generating transgenic animals with IL17 receptor A (IL17RA), which was genetically deleted from either the pancreatic epithelial compartment or the hematopoietic compartment via generation of IL17RA-deficient (IL17-RA-/-) bone marrow chimeras, in the context of embryonically activated or inducible Kras. Deletion of IL17RA from the pancreatic epithelial compartment, but not from …

Supporting Students’ Physical Activity Self-Efficacy Within High School Physical Education, Ken Murfay, Aaron Beighle, Heather Erwin, Erin Aiello, Sarah Pyszczynski

International Journal of Physical Activity and Health

Research examining physical activity (PA) is significant because of the known benefits of PA. Studying high school (HS) students is particularly important due to the consistent decline in PA as students age. One strategy to increase PA is to increase someone’s self-efficacy (confidence) to be physically active which is commonly positively associated with PA. Most of the research on how to support physical activity self-efficacy (PASE) comes from outside-of-school interventions with minimal literature on how to support students’ PASE within HS physical education (PE). This study attempted to identify and share practices that current HS PE teachers were implementing to …

Prostate-Specific Antigen Testing Patterns And Prostate Cancer Stage At Diagnosis In Older Ohio Cancer Patients, Sajan N. Patel, Long Vu, Holly E. Hartman, Weichuan Dong, Siran M. Koroukian, Johnie Rose

Faculty Scholarship

Background: Prostate cancer (PCa) screening recommendations do not support prostate-specific antigen (PSA) screening for older men. Such screening often occurs, however. It is, therefore, important to understand how frequently and among which subgroups screening occurs, and the extent of distant stage PCa diagnoses among screened older men. Methods: Using the 2014–2016 linked Ohio Cancer Incidence Surveillance System (OCISS) and Medicare administrative database, we identified men 68 and older diagnosed with PCa and categorized their PSA testing in the three years preceding diagnosis as screening or diagnostic. We conducted multivariable logistic regression analysis to identify correlates of screening PSA and to …

Background: Despite oral anticoagulation, patients with atrial fibrillation (AF) remain at risk of ischemic stroke and systemic embolism (SE) events. For patients whose residual risk is sufficiently high, additional therapies might be useful to mitigate stroke risk.

Methods and results: Individual patient data from 5 landmark trials testing oral anticoagulation in AF were pooled in A Collaboration Between Multiple Institutions to Better Investigate Non-Vitamin K Antagonist Oral Anticoagulant Use in AF (COMBINE AF). We calculated the rate of ischemic stroke/SE among oral anticoagulation-treated patients with a CHA₂DS₂-VASc score≥2, across strata of CHA₂DS₂-VASc …

Tomivosertib Reduces Ectopic Activity In Dorsal Root Ganglion Neurons From Patients With Radiculopathy, Yan Li, Megan L Uhelski, Robert Y North, Juliet M Mwirigi, Claudio E Tatsui, Kathleen E Mcdonough, Juan P Cata, German Corrales, Greg Dussor, Theodore J Price, Patrick M Dougherty

Faculty, Staff and Student Publications

Spontaneous activity in dorsal root ganglion (DRG) neurons is a key driver of neuropathic pain in patients suffering from this largely untreated disease. While many intracellular signalling mechanisms have been examined in preclinical models that drive spontaneous activity, none have been tested directly on spontaneously active human nociceptors.

Using cultured DRG neurons recovered during thoracic vertebrectomy surgeries, we showed that inhibition of mitogen-activated protein kinase interacting kinase (MNK) with tomivosertib (eFT508, 25 nM) reversibly suppresses spontaneous activity in human sensory neurons that are likely nociceptors based on size and action potential characteristics associated with painful dermatomes within minutes of treatment. …

Whole Genome Analysis Of Plasma Fibrinogen Reveals Population-Differentiated Genetic Regulators With Putative Liver Role, Jennifer E. Huffman, Jayna Nicholas, Julie Hahn, Adam S. Heath, Laura M. Raffield, Lisa R. Yanek, Jennifer A. Brody, Laura Almasy, Joanne E. Curran, John Blangero

School of Medicine Publications

Genetic studies have identified numerous regions associated with plasma fibrinogen levels in Europeans, yet missing heritability and limited inclusion of non-Europeans necessitates further studies with improved power and sensitivity. Compared with array-based genotyping, whole genome sequencing (WGS) data provides better coverage of the genome and better representation of non-European variants. To better understand the genetic landscape regulating plasma fibrinogen levels, we meta-analyzed WGS data from the NHLBI's Trans-Omics for Precision Medicine (TOPMed) program (n=32,572), with array-based genotype data from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium (n=131,340) imputed to the TOPMed or Haplotype Reference Consortium …

Higher levels of aneuploidy, characterized by imbalanced chromosome numbers, are associated with lethal progression in prostate cancer. However, how aneuploidy contributes to prostate cancer aggressiveness remains poorly understood. In this study, we assessed in patients which genes on chromosome 8q, one of the most frequently gained chromosome arms in prostate tumors, were most strongly associated with long-term risk of cancer progression to metastases and death from prostate cancer (lethal disease) in 403 patients and found the strongest candidate was cohesin subunit gene,

Solubility Change Behavior Of Fluoroalkyl Ether-Tagged Dendritic Hexaphenol Under Extreme Uv Exposure, Hyun-Taek Oh, Gayoung Kim, Seok-Heon Jung, Yejin Ku, Jin-Kyun Lee, Kanghyun Kim, Byeong-Gyu Park, Sangsul Lee, Chawon Koh, Tsunehiro Nishi, Hyun-Woo Kim

Staff and Researcher Publications

This study focuses on the discovery of a single-component molecular resist for extreme ultraviolet (EUV) lithography by employing the ionizing radiation-induced decomposition of carbon–fluorine chemical bonds. The target material, DHP-L6, was synthesized by bonding perfluoroalkyl ether moieties to amorphous dendritic hexaphenol (DHP) with a high glass transition temperature. Upon exposure to EUV and electron beam irradiation, DHP-L6 films exhibited a decreasing solubility in fluorous developer media, resulting in negative-tone images. The underlying chemical mechanisms were elucidated by Fourier transform-infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy, and nanoindentation experiments. These analyses highlighted the possible electron-induced decomposition of C–F bonds in DHP-L6, leading …

Changes In Multimorbidity Among Hospitalized Adults In The Us, Christine Loyd, Lauren Picken, Richelle Sanders, Yue Zhang, Richard E. Kennedy, Cynthia J. Brown

School of Medicine Faculty Publications

OBJECTIVE: This investigation examines burden of comorbidity measured by the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) among inpatients based on age, sex, and race. METHODS: Cross-sectional analysis of 2012-2018 US NIS datasets. Participants were inpatients 55y+. ICD-9/10 codes for admitting diagnoses were used to calculate disease burden using the CCI and ECI. Unweighted mean CCI and ECI scores were compared across demographic variables. RESULTS: An increase in mean CCI and ECI scores across age, sex, and races (p < .001) was identified. Compared to the youngest age group (55-59y), all age groups had higher mean CCI and ECI adjusting for time (p < .001). Increases were greatest in older age groups until age 80-84 for CCI and 85-89 for ECI. The female group had lower CCI adjusting for time (p < .001) compared to males. There was no difference between sex groups in mean ECI (p=.409). Compared with the White group, all other race groups had higher mean CCI adjusting for time (p < .001). Black inpatients had the highest CCI followed by Native American inpatients. Findings were similar for ECI, but with no difference between Hispanic and White groups (p=.434). CONCLUSIONS: Growing multimorbidity burden among adult inpatients across age, sex, and race supports the continued need for programs for preventing and reducing multimorbidity, especially among communities that experience health inequity including older, Black, and Native American patients.

Faculty, Staff and Students Publications

In metazoans mitochondrial DNA (mtDNA) or retrotransposon cDNA released to cytoplasm are degraded by nucleases to prevent sterile inflammation. It remains unknown whether degradation of these DNA also prevents nuclear genome instability. We used an amplicon sequencing-based method in yeast enabling analysis of millions of DSB repair products. In non-dividing stationary phase cells, Pol4-mediated non-homologous end-joining increases, resulting in frequent insertions of 1-3 nucleotides, and insertions of mtDNA (NUMTs) or retrotransposon cDNA. Yeast EndoG (Nuc1) nuclease limits insertion of cDNA and transfer of very long mtDNA ( >10 kb) to the nucleus, where it forms unstable circles, while promoting the …

Stabilization Of Interdomain Closure By A G Protein Inhibitor, Tyson D Todd, Neha Vithani, Sukrit Singh, Gregory R Bowman, Kendall J Blumer, Andrea Soranno

2020-Current year OA Pubs

Inhibitors of heterotrimeric G proteins are being developed as therapeutic agents. Epitomizing this approach are YM-254890 (YM) and FR900359 (FR), which are efficacious in models of thrombosis, hypertension, obesity, asthma, uveal melanoma, and pain, and under investigation as an FR-antibody conjugate in uveal melanoma clinical trials. YM/FR inhibits the Gq/11/14 subfamily by interfering with GDP (guanosine diphosphate) release, but by an unknown biophysical mechanism. Here, we show that YM inhibits GDP release by stabilizing closure between the Ras-like and α-helical domains of a Gα subunit. Nucleotide-free Gα adopts an ensemble of open and closed configurations, as indicated by single-molecule Förster …

Concurrent Ependymal And Ganglionic Differentiation In A Subset Of Supratentorial Neuroepithelial Tumors With Ewsr1-Plagl1 Rearrangement, Julieann C Lee, Sonika Dahiya, Kaleigh Roberts, Et Al.

2020-Current year OA Pubs

Neuroepithelial tumors with fusion of PLAGL1 or amplification of PLAGL1/PLAGL2 have recently been described often with ependymoma-like or embryonal histology respectively. To further evaluate emerging entities with PLAG-family genetic alterations, the histologic, molecular, clinical, and imaging features are described for 8 clinical cases encountered at St. Jude (EWSR1-PLAGL1 fusion n = 6; PLAGL1 amplification n = 1; PLAGL2 amplification n = 1). A histologic feature observed on initial resection in a subset (4/6) of supratentorial neuroepithelial tumors with EWSR1-PLAGL1 rearrangement was the presence of concurrent ependymal and ganglionic differentiation. This ranged from prominent clusters of ganglion cells within ependymoma/subependymoma-like areas, …
