AIMS: Abnormal intracellular calcium (Ca2+) handling contributes to the progressive nature of atrial fibrillation (AF), the most common sustained cardiac arrhythmia. Evidence in mouse models suggests that activation of the nuclear factor of activated T-cell (NFAT) signalling pathway contributes to atrial remodelling. Our aim was to determine the role of NFATc2 in AF in humans and mouse models.

METHODS AND RESULTS: Expression levels of NFATc1-c4 isoforms were assessed by quantitative reverse transcription-polymerase chain reaction in right atrial appendages from patients with chronic AF (cAF). NFATc1 and NFATc2 mRNA levels were elevated in cAF patients compared with those in normal sinus …

Faculty, Staff and Student Publications

Aluminum (Al) is a metallic toxicant at high concentrations following natural or unnatural exposures. Dietary intake is considered as the main source of aluminum exposure in children. We used data from 366 typically developing (TD) children (ages 2−8 years) who participated as controls in an age- and sex-matched case−control study in Jamaica. We investigated additive and interactive associations among environmental factors and children’s genotypes for glutathione S-transferase (GST) genes (GSTT1, GSTM1, GSTP1), in relation to having a detectable blood aluminum concentration (BAlC) of >5.0 μg/L, using multivariable logistic regression models. Findings from interactive models revealed that the odds of having …

Center on Aging Staff Publications

The study presents a novel approach to objectively assessing the upper-extremity motor symptoms in spinocerebellar ataxia (SCA) using data collected via a wearable sensor worn on the patient’s wrist during upper-extremity tasks associated with the Assessment and Rating of Ataxia (SARA). First, we developed an algorithm for detecting/extracting the cycles of the finger-to-nose test (FNT). We extracted multiple features from the detected cycles and identified features and parameters correlated with the SARA scores. Additionally, we developed models to predict the severity of symptoms based on the FNT. The proposed technique was validated on a dataset comprising the seventeen (n …

There is a growing body of evidence that therapy-related myeloid neoplasms (t-MNs) with driver gene mutations arise in the background of clonal hematopoiesis (CH) under the positive selective pressure of chemo- and radiation therapies. Uncovering the exposure relationships that provide selective advantage to specific CH mutations is critical to understanding the pathogenesis and etiology of t-MNs. In a systematic analysis of 416 patients with t-MN and detailed prior exposure history, we found that TP53 mutations were significantly associated with prior treatment with thalidomide analogs, specifically lenalidomide. We demonstrated experimentally that lenalidomide treatment provides a selective advantage to Trp53-mutant hematopoietic stem …

Faculty, Staff and Students Publications

Ribosomal RNAs (rRNAs) are the most abundant cellular RNAs, and their synthesis from rDNA repeats by RNA polymerase I accounts for the bulk of all transcription. Despite substantial variation in rRNA transcription rates across cell types, little is known about cell-type-specific factors that bind rDNA and regulate rRNA transcription to meet tissue-specific needs. Using hematopoiesis as a model system, we mapped about 2,200 ChIP-seq datasets for 250 transcription factors (TFs) and chromatin proteins to human and mouse rDNA and identified robust binding of multiple TF families to canonical TF motifs on rDNA. Using a 47S-FISH-Flow assay developed for nascent rRNA …

Children’s Nutrition Research Center Staff Publications

Objective: Although mood and anxiety symptoms are common in youth with type 1 diabetes (T1D), little research has described their worries across developmental stages or the strategies they use to cope with these worries. This secondary data analysis aimed to describe and characterize common T1D-related worries and coping strategies from middle childhood through young adulthood.

Methods: Twenty-three youth (9 children, 7 adolescents, and 7 young adults) completed semistructured qualitative interviews about health-related quality of life. We coded interview transcripts using thematic analysis to generate common themes of diabetes-related worries and coping strategies.

Results: Participants' worries fell into four major themes: …

No Longer Beholden – Moving On From Elaborate Chart Notes, Jeffrey H. Millstein

Journal of Wellness

Despite recent changes in Medicare billing documentation guidelines, physician chart notes remain far lengthier and more detailed than is required. This is worrisome, as documentation burden is a major contributor to physician burnout. Elements of medical culture which have contributed to the elaborate chart note standard may be used to transform notes, reduce charting burden and improve physician well-being.

Hdac6 Inhibition Reverses Cisplatin-Induced Mechanical Hypersensitivity Via Tonic Delta Opioid Receptor Signaling, Jixiang Zhang, Jazzmine M Junigan, Ronnie Trinh, Annemieke Kavelaars, Cobi J Heijnen, Peter M Grace

Faculty, Staff and Student Publications

Peripheral neuropathic pain induced by the chemotherapeutic cisplatin can persist for months to years after treatment. Histone deacetylase 6 (HDAC6) inhibitors have therapeutic potential for cisplatin-induced neuropathic pain since they persistently reverse mechanical hypersensitivity and spontaneous pain in rodent models. Here, we investigated the mechanisms underlying reversal of mechanical hypersensitivity in male and female mice by a 2 week treatment with an HDAC6 inhibitor, administered 3 d after the last dose of cisplatin. Mechanical hypersensitivity in animals of both sexes treated with the HDAC6 inhibitor was temporarily reinstated by a single injection of the neutral opioid receptor antagonist 6β-naltrexol or …

Anterior Connectivity Critical For Recovery Of Connected Speech After Stroke, Junhua Ding, Tatiana T Schnur

Faculty, Staff and Student Publications

Connected speech recovers to different degrees across people after left hemisphere stroke, but white matter predictors of differential recovery from the acute stage of stroke are unknown. We assessed changes in lexical-syntactic aspects of connected speech in a longitudinal analysis of 40 individuals (18 females) from the acute stage of left hemisphere stroke (within an average of 4 days post-stroke) to subacute (within 2 months) and chronic stages (early: 6 months, late: 1 year) while measuring the extent of acute lesions on white matter tracts to identify tracts predictive of recovery. We found that acute damage to the frontal aslant …

Mapping The Universe Of Eph Receptor And Ephrin Ligand Transcripts In Epithelial And Fiber Cells Of The Eye Lens, Michael P Vu, Catherine Cheng

Faculty, Staff and Student Publications

The eye lens is a transparent, ellipsoid organ in the anterior chamber of the eye that is required for fine focusing of light onto the retina to transmit a clear image. Cataracts, defined as any opacity in the lens, remains the leading cause of blindness in the world. Recent studies in humans and mice indicate that Eph-ephrin bidirectional signaling is important for maintaining lens transparency. Specifically, mutations and polymorphisms in the EphA2 receptor and the ephrin-A5 ligand have been linked to congenital and age-related cataracts. It is unclear what other variants of Ephs and ephrins are expressed in the lens …

Estimating The Optimal Linear Combination Of Predictors Using Spherically Constrained Optimization, Priyam Das, Debsurya De, Raju Maiti, Mona Kamal, Katherine A Hutcheson, Clifton D Fuller, Bibhas Chakraborty, Christine B Peterson

Faculty, Staff and Student Publications

Background: In the context of a binary classification problem, the optimal linear combination of continuous predictors can be estimated by maximizing the area under the receiver operating characteristic curve. For ordinal responses, the optimal predictor combination can similarly be obtained by maximization of the hypervolume under the manifold (HUM). Since the empirical HUM is discontinuous, non-differentiable, and possibly multi-modal, solving this maximization problem requires a global optimization technique. Estimation of the optimal coefficient vector using existing global optimization techniques is computationally expensive, becoming prohibitive as the number of predictors and the number of outcome categories increases.

Results: We propose an …

Therapeutic Efficacy Of The Humanized Jaa-F11 Anti-Thomsen-Friedenreich Antibody Constructs H2al2a And H3l3 In Human Breast And Lung Cancer Xenograft Models, Diala Ghazal, Fatma Zalzala, John C Fisk, Swetha Tati, Loukia G Karacosta, Susan Morey, James R Olson, Sally Quataert, Grace K Dy, Kate Rittenhouse-Olson

Faculty, Staff and Student Publications

The Thomsen-Friedenreich antigen (TF-Ag-α) is found on ~85% of human carcinomas but is cryptic on normal tissue. The humanized highly specific hJAA-F11-H2aL2a and -H3L3 antibodies target TF-Ag-α without binding to TF-Ag-beta (found on surface glycolipids of some normal cells). The relative affinity of H3L3 is 17 times that of H2aL2a, which would seem to favor superior efficacy, however, increased affinity can result in less tumor penetration. To assess the potential therapeutic efficacy of these antibodies, four human cancer- mouse xenograft models were treated with H2aL2a and H3L3. The tumor xenograft models used were human non-small cell lung cancer, H520, and …

The Modifying Effect Of The Serum-To-Dialysate Potassium Gradient On The Cardiovascular Safety Of Ssris In The Hemodialysis Population: A Pharmacoepidemiologic Study, Magdalene M Assimon, Patrick H Pun, Sana M Al-Khatib, Maurice Alan Brookhart, Bradley N Gaynes, Wolfgang C Winkelmayer, Jennifer E Flythe

Faculty, Staff and Students Publications

Background: Hypokalemia is a risk factor for drug-induced QT prolongation. Larger serum-to-dialysate potassium gradients during hemodialysis (HD) may augment the proarrhythmic risks of selective serotonin reuptake inhibitors (SSRIs).

Methods: We conducted a cohort study using 2007-2017 data from the United States Renal Data System and a large dialysis provider to examine if the serum-to-dialysate potassium gradient modifies SSRI cardiac safety. Using a new-user design, we compared 1-year sudden cardiac death (SCD) risk among HD patients newly treated with higher (citalopram, escitalopram) versus lower (fluoxetine, fluvoxamine, paroxetine, sertraline) QT-prolonging potential SSRIs, overall and stratified by baseline potassium gradient (≥4 versus < 4 mEq/l). We used inverse probability of treatment-weighted survival models to estimate weighted hazard ratios (HRs) and 95% confidence intervals (CIs) and conducted a confirmatory nested case-control study.

Loss Of Activity-Induced Mitochondrial Atp Production Underlies The Synaptic Defects In A Drosophila Model Of Als, Nicholas E Karagas, Richa Gupta, Elham Rastegari, Kai Li Tan, Ho Hang Leung, Hugo J Bellen, Kartik Venkatachalam, Ching-On Wong

Faculty, Staff and Students Publications

Mutations in the gene encoding vesicle-associated membrane protein B (VAPB) cause a familial form of amyotrophic lateral sclerosis (ALS). Expression of an ALS-related variant of vapb (vapb^P58S) in Drosophila motor neurons results in morphologic changes at the larval neuromuscular junction (NMJ) characterized by the appearance of fewer, but larger, presynaptic boutons. Although diminished microtubule stability is known to underlie these morphologic changes, a mechanism for the loss of presynaptic microtubules has been lacking. By studying flies of both sexes, we demonstrate the suppression of vapb^P58S-induced changes in NMJ morphology by either a loss of endoplasmic …

Daphnia As A Sentinel Species For Environmental Health Protection: A Perspective On Biomonitoring And Bioremediation Of Chemical Pollution, Muhammad Abdullahi, Xiaojing Li, Mohamed Abou-Elwafa Abdallah, William Stubbings, Norman Yan, Marianne Barnard, Liang-Hong Guo, John K Colbourne, Luisa Orsini

Faculty, Staff and Student Publications

Despite available technology and the knowledge that chemical pollution damages human and ecosystem health, chemical pollution remains rampant, ineffectively monitored, rarely prevented, and only occasionally mitigated. We present a framework that helps address current major challenges in the monitoring and assessment of chemical pollution by broadening the use of the sentinel species Daphnia as a diagnostic agent of water pollution. And where prevention has failed, we propose the application of Daphnia as a bioremediation agent to help reduce hazards from chemical mixtures in the environment. By applying “omics” technologies to Daphnia exposed to real-world ambient chemical mixtures, we show improvements …
