Distinct Intrinsic And Extrinsic Factors Differentially Regulate Skeletal Stem Cells In Calvaria Versus Long Bones During Bone Regeneration, Jea Solidum, Kohei Yamasaki, Youngjae Jeong, Laura Ortinau, Francisco Heralde, Dongsu Park

Faculty, Staff and Students Publications

Calvarial suture skeletal stem cells (Su-SSCs) are a distinct stem cell population for craniofacial bone formation by intramembranous ossification, compared to long bone periosteal SSCs (LB-PSSCs) with endochondral (osteochondrogenic) ossification. However, whether SSC intrinsic or extrinsic factors affect their differentiation process has not been well elucidated. Here, using an inducible Prx1-CreER-EGFP+/−;Rosa26-tdTomato mouse model, we observed that endogenous Prx1+ Su-SSCs and their orthotopic transplantation into calvarial injury do not form cartilage intermediates at the injury sites, while the transplantation of Prx1+ LB-PSSCs into LB injury induces osteochondrogenic differentiation, respectively. However, the heterotopic transplantation of Prx1+ Su-SSCs (Su-SSCs …

The use of guideline-directed medical therapy (GDMT) has substantially prolonged and improved the lives of patients with heart failure (HF). Nevertheless, adherence rates remain suboptimal. Even when successfully maximized and adhered to, there is a substantial residual risk of recurrent HF hospitalization and death. In light of this, there is a strong need for effective interventions that can decrease the high residual risk seen in patients with HF. Several device options exist that are approved by the US Food and Drug Administration and that have been shown to decrease morbidity and/or mortality in patients among whom GDMT is maximized. These …

The lysosome integrates anabolic signaling and nutrient sensing to regulate intracellular growth pathways. The leucine-rich repeat-containing 8 (LRRC8) channel complex forms a lysosomal anion channel and regulates PI3K-AKT-mTOR signaling, skeletal muscle differentiation, growth, and systemic glucose metabolism. Here, we define the endogenous LRRC8 subunits localized to a subset of lysosomes in differentiated myotubes. We show that LRRC8A affects leucine-stimulated mTOR; lysosome size; number; pH; expression of lysosomal proteins LAMP2, P62, and LC3B; and lysosomal function. Mutating an LRRC8A lysosomal targeting dileucine motif sequence (LRRC8A-L706A;L707A) in myotubes recapitulates the abnormal AKT signaling and altered lysosomal morphology and pH observed in LRRC8A …

Ciliated biobots (CiliaBots) are engineered tissues capable of self-actuated propulsion via exterior motile cilia. While correlations have been observed between CiliaBot motility and morphology, direct control of morphological features to deliver desired motility outcomes remains unexplored. Here, we describe the engineering of aggregated CiliaBots (AggreBots) to augment control over CiliaBot structural parameters and, consequently, motility patterns through guided, modular aggregation of human airway epithelial spheroids [referred to as CiliaBot building blocks (CBBs)]. Multi-CBB aggregation generated rod-, triangle-, and diamond-shaped AggreBots, altering tissue geometry without sacrificing surface cilia density or inter-CBB boundary fidelity.

The interaction of host and Ebola virus (EBOV) proteins is required for establishing infection. In this study, we use proximity-dependent biotinylation to identify cellular proteins that bind to EBOV proteins encoded by six of the seven viral genes. Hits are computationally mapped onto a human protein-protein interactome and annotated with viral proteins, confirming known EBOV-host protein interactions and revealing previously undescribed interactions and processes. This approach efficiently arranges proteins into functional complexes associated with single viral proteins. Focused characterization of interactions between EBOV VP35 and the mRNA decapping complex shows that VP35 binds the scaffold protein EDC4 through the C-terminal …

Neutrophil Degranulation Is Increased At Seven Days After Human Intracerebral Hemorrhage, But Not At 72 H, And Correlates With Decreased Mir-3613 And Mir-3690, Kyle B Walsh, Miranda C Marion, Dengfeng Li, Hannah C Ainsworth, Amy Zinnia, Xiang Zhang, Stacie L Demel, Brady Williamson, David J Roh, Robert Campbell, Frederik Denorme, Daniel Woo, Carl D Langefeld

BACKGROUND: The molecular mechanisms of inflammatory pathophysiology after intracerebral hemorrhage (ICH) are not well established. We report mRNA-seq and miRNA-seq in the peripheral blood of ICH patients with three serial samples during the first week after the stroke. METHODS: Twenty-seven ICH patients were enrolled via 24/7 screening and peripheral blood sampled at <  24 h (baseline), 72 h (+/-12 h), and 7 days (+/- 2 days) from last known normal. mRNA-seq and miRNA-seq were assessed for differential expression (DE) between the time point comparisons. Pathways identified via enrichment analysis (STRING, Reactome, Ingenuity Pathway Analysis) were tested via paired t-test and principal component analysis (PCA). Correlations between miRNA/mRNA pairs were computed. RESULTS: For DE mRNA at 72 h vs. baseline, the main enriched pathways pertained to neuronal function and synaptic transmission; prominent neuron-related genes from these pathways are also implicated in platelet activation. For 7 days vs. baseline, neutrophil degranulation and ribosomal biogenesis were the most enriched pathways; PCA also suggested neutrophil degranulation was the pathway most significantly different at 7 days vs. baseline compared with 72 h vs. baseline (p = 0.02). miR-3613 and miR-3690 had decreased expression at 7 days and were the miRNA most correlated with DE genes from the neutrophil degranulation pathway. CONCLUSION: Neutrophil degranulation was the prominent enriched pathway at 7 days after ICH and correlated with decreased miR-3613 and miR-3690. Further research is warranted of neutrophils in post-ICH inflammatory pathophysiology and functional validation studies of miR-3613 and miR-3690 as potential regulators of neutrophil degranulation after ICH.

Background: Calcium (Ca2+) dysregulation is a hallmark of heart failure, impairing excitation-contraction coupling and contributing to pathological remodeling. The sarco/endoplasmic reticulum Ca2+ ATPase isoform 2a (SERCA2a) mediates Ca2+ reuptake into the sarcoplasmic reticulum (SR) during diastole, but its activity declines in failing hearts. DWORF (dwarf open reading frame), a newly identified cardiac microprotein, enhances SERCA2a activity and improves cardiomyocyte Ca2+ cycling and contractility. SR Ca2+ release also influences mitochondrial metabolism and ATP production. Here, we investigated whether DWORF overexpression improves SR Ca2+ handling, augments mitochondrial Ca2+ signaling, and protects against heart failure progression.

Methods: Transgenic and adeno-associated virus approaches were …

Background: Nicotine is known to influence metabolism and body weight, yet existing murine models of nicotine exposure often fail to replicate human smoking behaviors accurately. To address this gap, we designed a cost-effective, self-administered nicotine inhalation system that allows mice to voluntarily inhale nicotine vapor generated from e-liquid.

Results: Using this system, we investigated the metabolic effects of nicotine exposure in adult and adolescent mice. Adult mice exposed to nicotine vapor for 10 days exhibited significant weight loss, which was rapidly regained upon cessation, paralleling human smoking patterns. In contrast, adolescent mice did not lose weight during nicotine exposure but …

INTRODUCTION: Life-support limits (i.e., code status), the first step in the continuum of palliation and end-of-life (EoL) care, stem from decisions made by patients and their providers to align care near the EoL with patients' wishes. The pandemic created health care strain that may have influenced life-support limitation practices among patients with serious COVID-19. In this study, we examine variations in life-support limitations (do-not-resuscitate, DNR; do-not-intubate, DNI) depending on the hospital and period of hospitalization.

METHODS: We included all adults admitted to a hospital in the United States with COVID-19 from January 2020 to December 2021 using the VIRUS registry. …

Er Stress Tolerance Is Regulated By Copper-Dependent Perk Kinase Activity., Sarah E. Bond Newton, Xinglong Shi, Noah R. Beratan, Julia Perhacs, Jitendra K. Arya, Margaret K. Bond, Tali Gidalevitz, Cagla Akay-Espinoza, Donita C. Brady, Kelly L. Jordan-Sciutto

Farber Institute for Neuroscience Faculty Papers

Pancreatic/PKR-like endoplasmic reticulum (ER) kinase (PERK) is a kinase that, in response to ER stress, mediates dual homeostatic and pro-apoptotic signaling. Thus, intricate regulation is required for physiological function. Attempts to modulate PERK activity have shown that the determinants of adaptive vs. maladaptive signaling remain ambiguous. Here, with purified protein, we provide evidence that PERK binds copper, identifies residues required for interaction, and demonstrates that copper is necessary for kinase activity. Furthermore, cellular PERK activity can be modulated via copper availability, and this regulatory relationship can be manipulated to dictate ER stress tolerance. Critically, these phenomena translate to phenotypes in …
