2020-Current year OA Pubs

BACKGROUND: Dedifferentiated chondrosarcoma (DDCS) is a rare subset of chondrosarcoma. It is an aggressive neoplasm characterized by a high rate of recurrent and metastatic disease with overall poor outcomes. Systemic therapy is often used to treat DDCS; however, the optimal regimen and timing are not well defined, with current guidelines recommending following osteosarcoma protocols.

METHODS: We conducted a multi-institutional retrospective analysis of clinical characteristics and outcomes of patients with DDCS. Between 1 January 2004 and 1 January 2022, the databases from five academic sarcoma centers were reviewed. Patient and tumor factors, including age, sex, tumor size, site, location, the treatments …

Developments In Stem Cell-Derived Islet Replacement Therapy For Treating Type 1 Diabetes, Nathaniel J Hogrebe, Matthew Ishahak, Jeffrey R Millman

2020-Current year OA Pubs

The generation of islet-like endocrine clusters from human pluripotent stem cells (hPSCs) has the potential to provide an unlimited source of insulin-producing β cells for the treatment of diabetes. In order for this cell therapy to become widely adopted, highly functional and well-characterized stem cell-derived islets (SC-islets) need to be manufactured at scale. Furthermore, successful SC-islet replacement strategies should prevent significant cell loss immediately following transplantation and avoid long-term immune rejection. This review highlights the most recent advances in the generation and characterization of highly functional SC-islets as well as strategies to ensure graft viability and safety after transplantation.

Organizational Readiness To Implement Task-Strengthening Strategy For Hypertension Management Among People Living With Hiv In Nigeria, Juliet Iwelunmor, Daphne Lew, Et Al.

2020-Current year OA Pubs

BACKGROUND: Hypertension (HTN) is highly prevalent among people living with HIV (PLHIV), but there is limited access to standardized HTN management strategies in public primary healthcare facilities in Nigeria. The shortage of trained healthcare providers in Nigeria is an important contributor to the increased unmet need for HTN management among PLHIV. Evidence-based TAsk-Strengthening Strategies for HTN control (TASSH) have shown promise to address this gap in other resource-constrained settings. However, little is known regarding primary health care facilities' capacity to implement this strategy. The objective of this study was to determine primary healthcare facilities' readiness to implement TASSH among PLHIV …

Infection Of Neonatal Mice With The Murine Norovirus Strain Wu23 Is A Robust Model To Study Norovirus Pathogenesis, Amy M Peiper, Emily W Helm, Quyen Nguyen, Matthew Phillips, Caroline G Williams, Dhairya Shah, Sarah Tatum, Neha Iyer, Marco Grodzki, Laura B Eurell, Aqsa Nasir, Megan T Baldridge, Stephanie M Karst

Noroviruses are the leading cause of severe childhood diarrhea and foodborne disease worldwide. While they are a major cause of disease in all age groups, infections in the very young can be quite severe, with annual estimates of 50,000-200,000 fatalities in children under 5 years old. In spite of the remarkable disease burden associated with norovirus infections, very little is known about the pathogenic mechanisms underlying norovirus diarrhea, principally because of the lack of tractable small animal models. The development of the murine norovirus (MNV) model nearly two decades ago has facilitated progress in understanding host-norovirus interactions and norovirus strain …

Associations Between Cannabis Use, Polygenic Liability For Schizophrenia, And Cannabis-Related Experiences In A Sample Of Cannabis Users, Emma C Johnson, Sarah M C Colbert, Paul W Jeffries, Rebecca Tillman, Nicole R Karcher, Elliot C Nelson, Arpana Agrawal, Et Al.

2020-Current year OA Pubs

BACKGROUND AND HYPOTHESIS: Risk for cannabis use and schizophrenia is influenced in part by genetic factors, and there is evidence that genetic risk for schizophrenia is associated with subclinical psychotic-like experiences (PLEs). Few studies to date have examined whether genetic risk for schizophrenia is associated with cannabis-related PLEs.

STUDY DESIGN: We tested whether measures of cannabis involvement and polygenic risk scores (PRS) for schizophrenia were associated with self-reported cannabis-related experiences in a sample ascertained for alcohol use disorders (AUDs), the Collaborative Study on the Genetics of Alcoholism (COGA). We analyzed 4832 subjects (3128 of European ancestry and 1704 of African …

Whole-Exome Sequencing Prioritizes Candidate Genes For Hereditary Cataract In The Emory Mouse Mutant, Thomas M Bennett, Yuefang Zhou, Kacie J Meyer, Michael G Anderson, Alan Shiels

2020-Current year OA Pubs

The Emory cataract (Em) mouse mutant has long been proposed as an animal model for age-related or senile cataract in humans-a leading cause of visual impairment. However, the genetic defect(s) underlying the autosomal dominant Em phenotype remains elusive. Here, we confirmed development of the cataract phenotype in commercially available Em/J mice [but not ancestral Carworth Farms White (CFW) mice] at 6-8 months of age and undertook whole-exome sequencing of candidate genes for Em. Analysis of coding and splice-site variants did not identify any disease-causing/associated mutations in over 450 genes known to underlie inherited and age-related forms of cataract and other …

Katp Channels Are Necessary For Glucose-Dependent Increases In Amyloid-Β And Alzheimer's Disease-Related Pathology, John Grizzanti, William R. Moritz, Molly Stanley, Emily E. Caesar, Maria S. Remedi, Celeste M. Karch, Colin G. Nichols, David M. Holtzman, Et Al.

2020-Current year OA Pubs

Elevated blood glucose levels, or hyperglycemia, can increase brain excitability and amyloid-β (Aβ) release, offering a mechanistic link between type 2 diabetes and Alzheimer's disease (AD). Since the cellular mechanisms governing this relationship are poorly understood, we explored whether ATP-sensitive potassium (KATP) channels, which couple changes in energy availability with cellular excitability, play a role in AD pathogenesis. First, we demonstrate that KATP channel subunits Kir6.2/KCNJ11 and SUR1/ABCC8 were expressed on excitatory and inhibitory neurons in the human brain, and cortical expression of KCNJ11 and ABCC8 changed with AD pathology in humans and mice. Next, we explored whether eliminating neuronal …

State-Level Macro-Economic Factors Moderate The Association Of Low Income With Brain Structure And Mental Health In U.S. Children, David G Weissman, Mark L Hatzenbuehler, Mina Cikara, Deanna M Barch, Katie A Mclaughlin

2020-Current year OA Pubs

Macrostructural characteristics, such as cost of living and state-level anti-poverty programs relate to the magnitude of socioeconomic disparities in brain development and mental health. In this study we leveraged data from the Adolescent Brain and Cognitive Development (ABCD) study from 10,633 9-11 year old youth (5115 female) across 17 states. Lower income was associated with smaller hippocampal volume and higher internalizing psychopathology. These associations were stronger in states with higher cost of living. However, in high cost of living states that provide more generous cash benefits for low-income families, socioeconomic disparities in hippocampal volume were reduced by 34%, such that …

Expanded Directly Binds Conserved Regions Of Fat To Restrain Growth Via The Hippo Pathway, Alexander D Fulford, Leonie Enderle, Jannette Rusch, Didier Hodzic, Maxine V Holder, Alex Earl, Robin Hyunseo Oh, Nicolas Tapon, Helen Mcneill

2020-Current year OA Pubs

The Hippo pathway is a conserved and critical regulator of tissue growth. The FERM protein Expanded is a key signaling hub that promotes activation of the Hippo pathway, thereby inhibiting the transcriptional co-activator Yorkie. Previous work identified the polarity determinant Crumbs as a primary regulator of Expanded. Here, we show that the giant cadherin Fat also regulates Expanded directly and independently of Crumbs. We show that direct binding between Expanded and a highly conserved region of the Fat cytoplasmic domain recruits Expanded to the apicolateral junctional zone and stabilizes Expanded. In vivo deletion of Expanded binding regions in Fat causes …

Tumor-Derived Interleukin-1Α And Leukemia Inhibitory Factor Promote Extramedullary Hematopoiesis, Derek A. G. Barisas, Ashraf Ul Kabir, Jun Wu, Karen Krchma, Minseo Kim, Madhav Subramanian, Bernd H. Zinselmeyer, Colin L. Stewart, Kyunghee Choi

2020-Current year OA Pubs

Extramedullary hematopoiesis (EMH) expands hematopoietic capacity outside of the bone marrow in response to inflammatory conditions, including infections and cancer. Because of its inducible nature, EMH offers a unique opportunity to study the interaction between hematopoietic stem and progenitor cells (HSPCs) and their niche. In cancer patients, the spleen frequently serves as an EMH organ and provides myeloid cells that may worsen pathology. Here, we examined the relationship between HSPCs and their splenic niche in EMH in a mouse breast cancer model. We identify tumor produced IL-1α and leukemia inhibitory factor (LIF) acting on splenic HSPCs and splenic niche cells, …

Capsular Polysaccharide Inhibits Vaccine-Induced O-Antigen Antibody Binding And Function Across Both Classical And Hypervirulent K2:O1 Strains Of Klebsiella Pneumoniae, Paeton L. Wantuch, Cory J. Knoot, Lloyd S. Robinson, Evgeny Vinogradov, Nichollas E. Scott, Christian M. Harding, David A. Rosen

2020-Current year OA Pubs

Klebsiella pneumoniae presents as two circulating pathotypes: classical K. pneumoniae (cKp) and hypervirulent K. pneumoniae (hvKp). Classical isolates are considered urgent threats due to their antibiotic resistance profiles, while hvKp isolates have historically been antibiotic susceptible. Recently, however, increased rates of antibiotic resistance have been observed in both hvKp and cKp, further underscoring the need for preventive and effective immunotherapies. Two distinct surface polysaccharides have gained traction as vaccine candidates against K. pneumoniae: capsular polysaccharide and the O-antigen of lipopolysaccharide. While both targets have practical advantages and disadvantages, it remains unclear which of these antigens included in a vaccine would …

Propranolol Reduces Ifn-Γ Driven Pd-L1 Immunosuppression And Improves Anti-Tumour Immunity In Ovarian Cancer, M Falcinelli, G Al-Hity, S Baron, M Mampay, M C Allen, M Samuels, W Jones, C Cilibrasi, Renee L Flaherty, G Giamas, P H Thaker, M S Flint

2020-Current year OA Pubs

The immune system plays an important role in controlling epithelial ovarian cancer (EOC). EOC is considered to be a "cold tumour," a tumour that has not triggered a strong response by the immune system. However, tumour infiltrating lymphocytes (TILs) and the expression of programmed cell death ligand (PD-L1) are used as prognostic indicators in EOC. Immunotherapy such as PD-(L)1 inhibitors have shown limited benefit in EOC. Since the immune system is affected by behavioural stress and the beta-adrenergic signalling pathway, this study aimed to explore the impact of propranolol (PRO), a beta-blocker, on anti-tumour immunity in both in vitro and …

Position Paper: Models Of Post-Transplant Care For Individuals With Cystic Fibrosis, Edward Mckone, Joshua Blatter, Ramsey Hachem, Et Al.

2020-Current year OA Pubs

There is no consensus on the best model of care for individuals with CF to manage the non-pulmonary complications that persist after lung transplant. The CF Foundation virtually convened a group of international experts in CF and lung-transplant care. The committee reviewed literature and shared the post-lung transplant model of care practiced by their programs. The committee then developed a survey that was distributed internationally to both the clinical and individual with CF/family audiences to determine the strengths, weaknesses, and preferences for various models of transplant care. Discussion generated two models to accomplish optimal CF care after transplant. The first …

Bk Channels Of Five Different Subunit Combinations Underlie The De Novo Kcnma1 G375r Channelopathy, Yanyan Geng, Ping Li, Alice Butler, Bill Wang, Lawrence Salkoff, Karl L Magleby

2020-Current year OA Pubs

The molecular basis of a severe developmental and neurological disorder associated with a de novo G375R variant of the tetrameric BK channel is unknown. Here, we address this question by recording from single BK channels expressed to mimic a G375R mutation heterozygous with a WT allele. Five different types of functional BK channels were expressed: 3% were consistent with WT, 12% with homotetrameric mutant, and 85% with three different types of hybrid (heterotetrameric) channels assembled from both mutant and WT subunits. All channel types except WT showed a marked gain-of-function in voltage activation and a smaller decrease-of-function in single-channel conductance, …

Blockade Of Trpv Channels By Intracellular Spermine, Grigory Maksaev, Peng Yuan, Colin G Nichols

2020-Current year OA Pubs

The Vanilloid thermoTRP (TRPV1-4) subfamily of TRP channels are involved in thermoregulation, osmoregulation, itch and pain perception, (neuro)inflammation and immune response, and tight control of channel activity is required for perception of noxious stimuli and pain. Here we report voltage-dependent modulation of each of human TRPV1, 3, and 4 by the endogenous intracellular polyamine spermine. As in inward rectifier K channels, currents are blocked in a strongly voltage-dependent manner, but, as in cyclic nucleotide-gated channels, the blockade is substantially reduced at more positive voltages, with maximal blockade in the vicinity of zero voltage. A kinetic model of inhibition suggests two …

Differential Regulation Of Cardiac Sodium Channels By Intracellular Fibroblast Growth Factors, Paweorn Angsutararux, Amal K Dutta, Martina Marras, Carlota Abella, Rebecca L Mellor, Jingyi Shi, Jeanne M Nerbonne, Jonathan R Silva

2020-Current year OA Pubs

Voltage-gated sodium (NaV) channels are responsible for the initiation and propagation of action potentials. In the heart, the predominant NaV1.5 α subunit is composed of four homologous repeats (I-IV) and forms a macromolecular complex with multiple accessory proteins, including intracellular fibroblast growth factors (iFGF). In spite of high homology, each of the iFGFs, iFGF11-iFGF14, as well as the individual iFGF splice variants, differentially regulates NaV channel gating, and the mechanisms underlying these differential effects remain elusive. Much of the work exploring iFGF regulation of NaV1.5 has been performed in mouse and rat ventricular myocytes in which iFGF13VY is the predominant …

Multifactorial Profiling Of Epigenetic Landscapes At Single-Cell Resolution Using Multi-Tag, Michael P Meers, Geneva Llagas, Derek H Janssens, Christine A Codomo, Steven Henikoff

2020-Current year OA Pubs

Chromatin profiling at locus resolution uncovers gene regulatory features that define cell types and developmental trajectories, but it remains challenging to map and compare different chromatin-associated proteins in the same sample. Here we describe Multiple Target Identification by Tagmentation (MulTI-Tag), an antibody barcoding approach for profiling multiple chromatin features simultaneously in single cells. We optimized MulTI-Tag to retain high sensitivity and specificity, and we demonstrate detection of up to three histone modifications in the same cell: H3K27me3, H3K4me1/2 and H3K36me3. We apply MulTI-Tag to resolve distinct cell types and developmental trajectories; to distinguish unique, coordinated patterns of active and repressive …

Heterozygous variants in the glucocerebrosidase (GBA) gene are common and potent risk factors for Parkinson's disease (PD). GBA also causes the autosomal recessive lysosomal storage disorder (LSD), Gaucher disease, and emerging evidence from human genetics implicates many other LSD genes in PD susceptibility. We have systemically tested 86 conserved fly homologs of 37 human LSD genes for requirements in the aging adult Drosophila brain and for potential genetic interactions with neurodegeneration caused by α-synuclein (αSyn), which forms Lewy body pathology in PD. Our screen identifies 15 genetic enhancers of αSyn-induced progressive locomotor dysfunction, including knockdown of fly homologs of GBA …

Identifying Regions Of Interest In Mammogram Images, Shu Jiang, Jiguo Cao, Graham A. Colditz

2020-Current year OA Pubs

Screening mammography is the primary preventive strategy for early detection of breast cancer and an essential input to breast cancer risk prediction and application of prevention/risk management guidelines. Identifying regions of interest within mammogram images that are associated with 5- or 10-year breast cancer risk is therefore clinically meaningful. The problem is complicated by the irregular boundary issue posed by the semi-circular domain of the breast area within mammograms. Accommodating the irregular domain is especially crucial when identifying regions of interest, as the true signal comes only from the semi-circular domain of the breast region, and noise elsewhere. We address …

First-In-Human Phase Ib Trial Of M9241 (Nhs-Il12) Plus Avelumab In Patients With Advanced Solid Tumors, Including Dose Expansion In Patients With Advanced Urothelial Carcinoma, Julius Strauss, Russell K. Pachynski, Et Al.

2020-Current year OA Pubs

BACKGROUND: In preclinical studies, combining M9241 (a novel immunocytokine containing interleukin (IL)-12 heterodimers) with avelumab (anti-programmed death ligand 1 antibody) resulted in additive or synergistic antitumor effects.
