Compared with high-grade serous carcinoma, low-grade serous carcinoma of the ovary or peritoneum is a less frequent epithelial ovarian cancer type that is poorly sensitive to chemotherapy and affects younger women, many of whom endure years of ineffective treatments and poor quality of life. The pathogenesis of this disease and its management remain incompletely understood. However, recent advances in the molecular characterization of the disease and identification of novel targeted therapies with activity in low-grade serous carcinoma offer the promise of improved outcomes. To update clinicians regarding recent scientific and clinical trial advancements and discuss unanswered questions related to low-grade …

Kv12-Encoded K+ Channels Drive The Day-Night Switch In The Repetitive Firing Rates Of Scn Neurons, Tracey O Hermanstyne, Nien-Du Yang, Daniel Granados-Fuentes, Xiaofan Li, Rebecca L Mellor, Timothy Jegla, Erik D Herzog, Jeanne M Nerbonne

2020-Current year OA Pubs

Considerable evidence suggests that day-night rhythms in the functional expression of subthreshold potassium (K+) channels regulate daily oscillations in the spontaneous firing rates of neurons in the suprachiasmatic nucleus (SCN), the master circadian pacemaker in mammals. The K+ conductance(s) driving these daily rhythms in the repetitive firing rates of SCN neurons, however, have not been identified. To test the hypothesis that subthreshold Kv12.1/Kv12.2-encoded K+ channels play a role, we obtained current-clamp recordings from SCN neurons in slices prepared from adult mice harboring targeted disruptions in the Kcnh8 (Kv12.1-/-) or Kcnh3 (Kv12.2-/-) locus. We found that mean nighttime repetitive firing rates …

It is increasingly assumed that there is no one-size-fits-all approach to dietary recommendations for the management and treatment of chronic diseases such as obesity. This phenomenon that not all individuals respond uniformly to a given treatment has become an area of research interest given the rise of personalized and precision medicine. To conduct, interpret, and disseminate this research rigorously and with scientific accuracy, however, requires an understanding of treatment response heterogeneity. Here, we define treatment response heterogeneity as it relates to clinical trials, provide statistical guidance for measuring treatment response heterogeneity, and highlight study designs that can quantify treatment response …

Platelets play crucial roles in the development and progression of coronary artery disease (CAD). The triggering receptor expressed in myeloid cells-like transcript-1 (TLT-1) is stored in platelet α granules, and activated platelets release a soluble fragment (sTLT-1). We set out to better characterize the constituent amino acids of sTLT-1 and to evaluate sTLT-1 for use as a biomarker in patients with stable CAD. We evaluated sTLT-1 release using immunoprecipitation and mass spectrometry and employed statistical methods to retrospectively correlate sTLT-1 concentrations, utilizing ELISA in plasma samples from 1510 patients with documented stable CAD. We identified TLT-1 residues to 133 in …

Determinants Of Ifgf13-Mediated Regulation Of Myocardial Voltage-Gated Sodium (Nav) Channels In Mouse, Adrien Lesage, Maxime Lorenzini, Sophie Burel, Marine Sarlandie, Floriane Bibault, Cecilia Lindskog, Daniel Maloney, Jonathan R Silva, R Reid Townsend, Jeanne M Nerbonne, Céline Marionneau

2020-Current year OA Pubs

Posttranslational regulation of cardiac NaV1.5 channels is critical in modulating channel expression and function, yet their regulation by phosphorylation of accessory proteins has gone largely unexplored. Using phosphoproteomic analysis of NaV channel complexes from adult mouse left ventricles, we identified nine phosphorylation sites on intracellular fibroblast growth factor 13 (iFGF13). To explore the potential roles of these phosphosites in regulating cardiac NaV currents, we abolished expression of iFGF13 in neonatal and adult mouse ventricular myocytes and rescued it with wild-type (WT), phosphosilent, or phosphomimetic iFGF13-VY. While the increased rate of closed-state inactivation of NaV channels induced by Fgf13 knockout in …

Mitochondrial Pyruvate Metabolism And Glutaminolysis Toggle Steady-State And Emergency Myelopoiesis, Hannah A Pizzato, Yahui Wang, Michael J Wolfgang, Brian N Finck, Gary J Patti, Deepta Bhattacharya

2020-Current year OA Pubs

To define the metabolic requirements of hematopoiesis, we examined blood lineages in mice conditionally deficient in genes required for long-chain fatty acid oxidation (Cpt2), glutaminolysis (Gls), or mitochondrial pyruvate import (Mpc2). Genetic ablation of Cpt2 or Gls minimally impacted most blood lineages. In contrast, deletion of Mpc2 led to a sharp decline in mature myeloid cells and a slower reduction in T cells, whereas other hematopoietic lineages were unaffected. Yet MPC2-deficient monocytes and neutrophils rapidly recovered due to a transient and specific increase in myeloid progenitor proliferation. Competitive bone marrow chimera and stable isotope tracing experiments demonstrated that this proliferative …

Autoantibodies Neutralizing Type I Ifns Underlie West Nile Virus Encephalitis In ∼40% Of Patients, Adrian Gervais, Shih-Ching Lin, Michael S Diamond, Et Al.

2020-Current year OA Pubs

Mosquito-borne West Nile virus (WNV) infection is benign in most individuals but can cause encephalitis in <1% of infected individuals. We show that ∼35% of patients hospitalized for WNV disease (WNVD) in six independent cohorts from the EU and USA carry auto-Abs neutralizing IFN-α and/or -ω. The prevalence of these antibodies is highest in patients with encephalitis (∼40%), and that in individuals with silent WNV infection is as low as that in the general population. The odds ratios for WNVD in individuals with these auto-Abs relative to those without them in the general population range from 19.0 (95% CI 15.0-24.0, P value <10-15) for auto-Abs neutralizing only 100 pg/ml IFN-α and/or IFN-ω to 127.4 (CI 87.1-186.4, P value <10-15) for auto-Abs neutralizing both IFN-α and IFN-ω at a concentration of 10 ng/ml. These antibodies block the protective effect of IFN-α in Vero cells infected with WNV in vitro. Auto-Abs neutralizing IFN-α and/or IFN-ω underlie ∼40% of cases of WNV encephalitis.

Biliary Dyskinesia In Stiff Person Syndrome: An Association Between Reduced Gaba Production And Gastroenteric Dysmotility, Scarlet Louis-Jean, Nirav Agrawal, Shire Chaudhry, Adrien Mazer

Journal of Community Hospital Internal Medicine Perspectives

Stiff person syndrome (SPS) and biliary dyskinesia are two rare but potentially debilitating conditions that can significantly impact quality of life. SPS is a rare neurological disorder characterized by muscle stiffness, rigidity, and muscle spasms that primarily affect the trunk and limbs and is associated with extra-axial manifestations involving the gastrointestinal tract. Biliary dyskinesia is a gastrointestinal disorder characterized by abnormal gallbladder emptying, leading to symptoms of intense abdominal pain, nausea, and vomiting. Despite their distinct clinical presentations, studies have suggested a possible connection between the two disorders. This link may be due to involvement of similar neurotransmitters and autoantibodies …

A Case Of Grave’S Thyrotoxicosis-Induced Takotsubo Cardiomyopathy Presenting With Cardiac Arrest After Winning The Lottery, David Philippides, Angelina Hong, Amanda Eukovich, Ali Chaudhry

HPD Articles

Takotsubo syndrome (TTS) is a nonischemic cardiomyopathy with transient apical ballooning of the left ventricle and reduced ejection fraction that can be caused by severe emotional or physical stress, with diverse clinical presentations. This case describes a patient who went into cardiac arrest at a casino after winning the lottery. She was found to have Takotsubo cardiomyopathy, in the setting of uncontrolled hyperthyroidism. This is a very unique case of TTS presenting with cardiac arrest, and is also an uncommon example of TTS triggered by a positive rather than negative emotional life event.

Integrate-Circ And Integrate-Vis: Unbiased Detection And Visualization Of Fusion-Derived Circular Rna, Jace Webster, Hung Mai, Amy Ly, Christopher Maher

2020-Current year OA Pubs

MOTIVATION: Backsplicing of RNA results in circularized rather than linear transcripts, known as circular RNA (circRNA). A recently discovered and poorly understood subset of circRNAs that are composed of multiple genes, termed fusion-derived circular RNAs (fcircRNAs), represent a class of potential biomarkers shown to have oncogenic potential. Detection of fcircRNAs eludes existing analytical tools, making it difficult to more comprehensively assess their prevalence and function. Improved detection methods may lead to additional biological and clinical insights related to fcircRNAs.

RESULTS: We developed the first unbiased tool for detecting fcircRNAs (INTEGRATE-Circ) and visualizing fcircRNAs (INTEGRATE-Vis) from RNA-Seq data. We found that …

Development Of A Culturally Adapted Dietary Intervention To Reduce Alzheimer's Disease Risk Among Older Black Adults, Ashley R Shaw, Mickeal N Key, Samantha Fikru, Saria Lofton, Debra K Sullivan, Jannette Berkley-Patton, Crystal M Glover, Jeffrey M Burns, Eric D Vidoni

Faculty, Staff and Student Publications

The objective of this study is to identify and understand knowledge and attitudes that influence dietary practices among older Black adults using a community-engaged approach. This is a non-interventional mixed methods study designed to inform the development of an adapted brain-healthy soul food diet intervention. A purposive sampling approach was used to conduct seven semi-structured focus group discussions and an online quantitative survey. In total, 39 participants who self-identified as Black, aged 55 years and older, English speaking, and who were cognitively normal with an AD8 < 2; (25.6% men; 74.4% women) participated in the online survey and one of the seven 60 min virtual focus group discussions (5-7 per focus group). Quantitative frequency data from the online surveys were analyzed using descriptive statistics. Qualitative focus group data were analyzed using a 6-step thematic analysis process. Five themes emerged: dementia awareness; practices shaping food choices and consumption; barriers to eating healthy; instrumental support; and elements of a culturally adapted brain-healthy dietary intervention. Older Black adults perceived an adapted MIND dietary model as the most acceptable with the incorporation of salient cultural characteristics and strategies within both the design and delivery phases.

Taz2 Truncation Confers Overactivation Of P300 And Cellular Vulnerability To Hdac Inhibition, Longxia Xu, Hongwen Xuan, Wei He, Liang Zhang, Mengying Huang, Kuai Li, Hong Wen, Han Xu, Xiaobing Shi

Faculty, Staff and Student Publications

The histone acetyltransferase p300/CBP is composed of several conserved domains, among which, the TAZ2 domain is known as a protein-protein interaction domain that binds to E1A and various transcription factors. Here we show that TAZ2 has a HAT autoinhibitory function. Truncating p300/CBP at TAZ2 leads to hyperactive HAT and elevated histone H3K27 and H3K18 acetylation in cells. Mechanistically, TAZ2 cooperates with other HAT neighboring domains to maintain the HAT active site in a 'closed' state. Truncating TAZ2 or binding of transcription factors to TAZ2 induces a conformational change that 'opens' the active site for substrate acetylation. Importantly, genetic mutations that …

Enhanced Presynaptic Mitochondrial Energy Production Is Required For Memory Formation, Erica L Underwood, John B Redell, Kimberly N Hood, Mark E Maynard, Michael Hylin, M Neal Waxham, Jing Zhao, Anthony N Moore, Pramod K Dash

Faculty, Staff and Student Publications

Some of the prominent features of long-term memory formation include protein synthesis, gene expression, enhanced neurotransmitter release, increased excitability, and formation of new synapses. As these processes are critically dependent on mitochondrial function, we hypothesized that increased mitochondrial respiration and dynamics would play a prominent role in memory formation. To address this possibility, we measured mitochondrial oxygen consumption (OCR) in hippocampal tissue punches from trained and untrained animals. Our results show that context fear training significantly increased basal, ATP synthesis-linked, and maximal OCR in the Shaffer collateral-CA1 synaptic region, but not in the CA1 cell body layer. These changes were …

Aenmd: Annotating Escape From Nonsense-Mediated Decay For Transcripts With Protein-Truncating Variants, Jonathan Klonowski, Qianqian Liang, Zeynep Coban-Akdemir, Cecilia Lo, Dennis Kostka

Faculty, Staff and Student Publications

DNA changes that cause premature termination codons (PTCs) represent a large fraction of clinically relevant pathogenic genomic variation. Typically, PTCs induce transcript degradation by nonsense-mediated mRNA decay (NMD) and render such changes loss-of-function alleles. However, certain PTC-containing transcripts escape NMD and can exert dominant-negative or gain-of-function (DN/GOF) effects. Therefore, systematic identification of human PTC-causing variants and their susceptibility to NMD contributes to the investigation of the role of DN/GOF alleles in human disease. Here we present aenmd, a software for annotating PTC-containing transcript-variant pairs for predicted escape from NMD. aenmd is user-friendly and self-contained. It offers functionality not currently available …

Acorn: An R Package For De Novo Variant Analysis, Tychele N Turner

2020-Current year OA Pubs

BACKGROUND: The study of de novo variation is important for assessing biological characteristics of new variation and for studies related to human phenotypes. Software programs exist to call de novo variants and programs also exist to test the burden of these variants in genomic regions; however, I am unaware of a program that fits in between these two aspects of de novo variant assessment. This intermediate space is important for assessing the quality of de novo variants and to understand the characteristics of the callsets. For this reason, I developed an R package called acorn.

RESULTS: Acorn is an R …
