BACKGROUND: Germline RUNX1 haplodeficiency (RHD) is associated with thrombocy- topenia, platelet dysfunction, and predisposition to myeloid malignancies. Platelet expression profiling of an RHD patient showed decreased F13A1, encoding for the A subunit of factor (F)XIII, a transglutaminase that cross-links fibrin and induces clot stabilization. FXIII-A is synthesized by hematopoietic cells, megakaryocytes, and monocytes.

OBJECTIVES: o understand RUNX1 regulation of F13A1 expression in platelets/mega- karyocytes and the mechanisms and consequences of decreased F13A1 in RHD.

METHODS: We performed studies in platelets, human erythroleukemia (HEL) cells, and human CD34+ cell-derived megakaryocytes including on clot contraction in cells following small inhibitor RNA knockdown …

Skeletal And Dental Tissue Mineralization: The Potential Role Of The Endoplasmic Reticulum/Golgi Complex And The Endolysosomal And Autophagic Transport Systems, Irving M. Shapiro, Makarand V. Risbud, Tengteng Tang, William J. Landis

Department of Orthopaedic Surgery Faculty Papers

This paper presents a review of the potential role of the endoplasmic reticulum/Golgi complex and intracellular vesicles in mediating events leading to or associated with vertebrate tissue mineralization. The possible importance of these organelles in this process is suggested by observations that calcium ions accumulate in the tubules and lacunae of the endoplasmic reticulum and Golgi. Similar levels of calcium ions (approaching millimolar) are present in vesicles derived from endosomes, lysosomes and autophagosomes. The cellular level of phosphate ions in these organelles is also high (millimolar). While the source of these ions for mineral formation has not been identified, there …

Zinc Promotes Mitochondrial Health Through Pgc-1alpha Enhancing Bacterial Clearance In Macrophages Infected With Mycobacterium Avium Complex, Ruxana Sadikot, Prabagaran Narayanasamy, Zhihong Yuan, Deandra R. Smith, Daren L. Knoell

Journal Articles: Pulmonary & Critical Care Med

Mitochondria are increasingly recognized as important contributors to immune function, in addition to energy production. They exert this influence through modulation of various signaling pathways that regulate cellular metabolism and immune function in response to pathogens. Peroxisome proliferator-activated receptor (PPAR) coactivator 1 alpha (PGC-1α) is the primary transcription factor and regulator involved in mitochondrial biogenesis. Long known to be involved in immune function, zinc (Zn) is also required for proper mitochondrial function. It is increasingly recognized that many cellular immunometabolic activities are also Zn-dependent. Taken together, we investigated the role of Zn deficiency, both dietary and genetically induced, and Zn …

Epigenetic Regulation In Fibrosis, Qingping Wei, Xiaoru Hu, Yan Sanders

Department of Biomedical and Translational Sciences Faculty Publications

[Introduction] Fibrosis is one of the pathological conditions underlying the progression of numerous chronic diseases, and it contributes substantially to morbidity and mortality worldwide. Increasing amounts of evidence indicate that epigenetic mechanisms—including DNA methylation, histone modifications, RNA modifications, and non-coding RNAs—play pivotal roles in epithelial cell injury and maladaptive tissue repair, inflammatory cell and fibroblast activation, and extracellular matrix remodeling and accumulation. Compared to genetic alterations, epigenetic changes are relatively reversible, positioning them as promising therapeutic targets. The articles collected in this Research Topic highlight recent advances in understanding how epigenetic regulation shapes fibrotic processes across multiple organ systems and …

Excitation And Polarization Of Isolated Neurons By High-Frequency Sine Waves For Temporal Interference Stimulation, Iurii Semenov, Vitalii Kim, Giedre Silkuniene, Andrei G. Pakhomov

Bioelectrics Publications

The capacity of temporal interference (TI) stimulation to target deep brain regions without affecting nearby surface electrodes remains uncertain. Using artifact-free optical recording, we compare excitation patterns and thresholds in hippocampal neurons stimulated by “pure” and amplitude-modulated sine waves, representing TI waveforms near electrodes and at the target, respectively. We show that pure 2- and 20-kHz sine waves induce repetitive firing at rates that increase up to 60–90 Hz with stronger electric fields. Beyond this limit, action potentials merge into sustained depolarization, resulting in an excitation block. Modulating the sine waves at 20 Hz aligns firing with amplitude “beats” and …

Time Of Urine Sampling May Influence The Association Between Urine Specific Gravity And Body Composition, Patrick B. Wilson, Brian K. Ferguson, Ian P. Winter

Exercise Science Faculty Publications

Urine specific gravity (USG) is frequently utilized in sports practice and research to assess hydration status. Prior research suggests that individuals with large amounts of fat-free mass (FFM) and muscle have elevated USG, but little is known about whether the time of collection (first-morning vs. spot sampling) and various nutritional factors influence these relationships. This cross-sectional, observational study assessed fasted first-morning (n = 55) and non-fasted spot USG (n = 51) samples in adults and evaluated relationships of USG with body composition and nutrition intake. The InBody 770 was used to estimate FFM, skeletal muscle mass (SMM), and total body …

The Short And Sweet On Sodium-Glucose Cotransporter Inhibitors And Glucagon-Like Peptide-1 Receptor Agonists In Heart Failure, Jose L. Batista, Tracy Makuvire, Jonathan D. Davis, Salvatore Carbone

EVMS School of Health Professions Faculty Publications

Heart failure (HF) affects 6 million people in the US, and type 2 diabetes (T2D) is a significant risk factor for HF. Since 2008, regulatory agencies have required cardiovascular safety trials for new T2D therapies, and these have consistently demonstrated the cardiovascular benefits of glucose-lowering drugs. Sodium-glucose cotransporter inhibitors (SGLTi) and glucagon-like peptide-1 (GLP-1) receptor agonists (RAs)/glucose-dependent insulinotropic polypeptide (GIP) reduce major adverse cardiovascular events and deaths, regardless of diabetes status, and improve cardiorespiratory fitness. SGLTis, such as dapagliflozin and empagliflozin, benefit patients with reduced and preserved ejection fraction, significantly reducing HF hospitalizations and cardiovascular deaths. The DAPA-HF and EMPEROR-Reduced …
