ADP-ribosylation is an enzyme-catalyzed post-translational modification of proteins in which the ADP-ribose (ADPR) moiety of NAD+ is transferred to a specific amino acid in a substrate protein. The biological functions of ADP-ribosylation are numerous and diverse, ranging from normal physiology to pathological conditions. Biochemical and cellular studies of the diverse forms and functions of ADPR require immunological reagents that can be used for detection and enrichment. The lack of a complete set of tools that recognize all forms of ADPR [i...

RUNX gene over-expression inhibits growth of primary cells but transforms cells with tumor suppressor defects, consistent with reported associations with tumor progression. In contrast, chromosomal translocations involving RUNX1 are detectable in utero, suggesting an initiating role in leukemias. How do cells expressing RUNX1 fusion oncoproteins evade RUNX-mediated growth suppression? Previous studies showed that the TEL-RUNX1 fusion from t(12;21) B-ALLs is unable to induce senescence-like growth arrest (SLGA) in primary fibroblasts while potent activity is displayed by the RUNX1-ETO fusion found in t(8;21) AMLs...

Aspergillus flavus is a saprophytic soil fungus that poses a serious threat worldwide as it contaminates many food and feed crops with the carcinogenic mycotoxin called aflatoxin. This pathogen persists as sclerotia in the soil which enables fungal survival in harsh environmental conditions. Sclerotia formation by A. flavus depends on successful cell communication and hyphal fusion events. Loss of LaeA, a conserved developmental regulator in fungi, abolishes sclerotia formation in this species whereas overexpression (OE) of laeA results in enhanced sclerotia production...

BACKGROUND: Autologous blood transfusion, commonly referred to as cell saver, is frequently used in spinal fusion to salvage red blood cells because of the risk of significant intraoperative blood loss. This case report describes a case of acute kidney injury (AKI) secondary to cell saver use. Our objective is to increase the knowledge about the process of red blood cell salvage and this exceedingly rare complication. METHODS: Chart and renal biopsy results for a single case were reviewed and reported in this retrospective study...

BACKGROUND: The purpose of our study was to assess the relationship between amount of blood loss and surgical stage in pediatric patients undergoing posterior spinal fusion for deformity correction to determine: (1) when the highest rate of blood loss occurred; (2) what percentage of total blood loss occurred during deformity correction and closure; and (3) how to predict remaining blood loss during a procedure. Blood loss following exposure and placement of the final pedicle screw is often underestimated, which may result in lack of sufficient blood product availability...

Hemophilia A is the most frequent inherited bleeding disorder and most challenging coagulation disorder. To combat this, a number of new improved rFVIII/IX concentrates have recently been approved. Some of them are derived from protein fusion biotechnology or pegylation to extend their half-life (HL). However, prophylaxis has become a standard of care to prevent arthropathy in hemophiliacs though the need of frequent venipunctures is a major obstacle to primary prophylaxis. The new Extended Half-Life (EHL) rFIX concentrates allow increased intervals, while the improved HL of new rFVIII was moderate...

Naturally occurring extracellular vesicles (EVs) play essential roles in intracellular communication and delivery of bioactive molecules. Therefore it has been suggested that EVs could be used for delivery of therapeutics. However, to date the therapeutic application of EVs has been limited by number of factors, including limited yield and full understanding of their biological activities. To address these issues, we analyzed the morphology, molecular composition, fusion capacity and biological activity of Cytochalasin B-induced membrane vesicles (CIMVs)...

The small ubiquitin-related modifier (SUMO) system is essential for smooth progression of cell cycle at the G2/M phase. Many centromeric proteins are reversibly SUMOylated to ensure proper chromosome segregation at the mitosis. SUMOylation of centromeric Origin Recognition Complex subunit 2 (ORC2) at the G2/M phase is essential in maintaining genome integrity. However, how ORC2 SUMOylation is regulated remains largely unclear. Here we show that ORC2 SUMOylation is reversibly controlled by SUMO E3 ligase PIAS4 and De-SUMOylase SENP2...

Exosomes are small vesicles with a molecular diameter of 30 to 100 nm, which are secreted into the cell after the fusion of the multivesicular bodies with the plasma membrane. Exosomes contain various molecular constituents of their cell origin, including proteins, microRNAs and lipids. Different cell-derived exosomes have different biological functions. Exosomes play a very important role in the development and progression of age-related macular degeneration (AMD). The exosomes derived from the eye are involved in the processes of cell growth, metastasis, angiogenesis and immunosuppression by transferring contents to adjacent or distant cells...

Anaplastic lymphoma kinase (ALK) fusion oncogenes occur in approximately 3-5% of non-small cell lung cancer (NSCLC) cases. Various ALK inhibitors are in clinical use for the treatment of ALK-NSCLC, including the first generation ALK inhibitor, crizotinib, and recently the more highly potent alectinib and ceritinib. However, most tumors eventually become resistant to ALK specific inhibitors. To address the mechanisms underlying the development of ALK inhibitor resistance, we used iTRAQ quantitative mass spectrometry and phosphor-receptor tyrosine kinase arrays to investigate intracellular signaling alterations in ALK inhibitor resistant NSCLC cell lines...

A2B adenosine receptor (A2BAR) is known to be the regulator of bone homeostasis, but its regulatory mechanisms in osteoclast formation are less well-defined. Here, we demonstrate the effect of A2BAR stimulation on osteoclast differentiation and activity by RANKL. A2BAR was expressed in bone marrow-derived monocyte/macrophage (BMM) and RANKL increased A2BAR expression during osteoclastogenesis. A2BAR stimulation with its specific agonist BAY 60-6583 was sufficient to inhibit the activation of ERK1/2, p38 MAP kinases and NF-κB by RANKL as well as it abrogated cell-cell fusion in the late stage of osteoclast differentiation...

Osteoclasts are bone-resorbing cells that are derived from hematopoietic precursor cells and require macrophage-colony stimulating factor and receptor activator of nuclear factor-κB ligand (RANKL) for their survival, proliferation, differentiation, and activation. The binding of RANKL to its receptor RANK triggers osteoclast precursors to differentiate into osteoclasts. This process depends on RANKL-RANK signaling, which is temporally regulated by various adaptor proteins and kinases. Here we summarize the current understanding of the mechanisms that regulate RANK signaling during osteoclastogenesis...

Enveloped viruses typically encode their own fusion machinery to enter cells. Herpesviruses are particular as they fuse with a number of cellular compartments throughout their life cycle. As the uncontrolled mixing of the host membranes should be avoided in these events, the tight regulation of the viral fusion machinery is critical. While studying the herpes simplex virus type 1 glycoprotein gM, we identified the cellular protein E-Syt1 (Extended synaptotagmin-1) as an interaction partner. This took place in both infected and transfected cells, suggesting other viral proteins were not required for this interaction...

Fluorescent protein fusions to herpesvirus capsids have proven to be a valuable method to study virus particle transport in living cells. Fluorescent protein fusions to the amino terminus of small capsid protein VP26 are the most widely-used method to visualize Pseudorabies Virus (PRV) and Herpes Simplex Virus (HSV) particles in living cells. However, these fusion proteins do not incorporate to full occupancy, and have modest effects on virus replication and pathogenesis. Recent cryo electron microscopy studies have revealed that herpesvirus small capsid proteins bind to capsids via their amino terminus, whereas the carboxy terminus is unstructured and may therefore better tolerate fluorescent protein fusions...

Conserved across the Herpesviridae family, glycoprotein B (gB) is responsible for driving fusion of the viral envelope with the host cell membrane for entry upon receptor binding and activation by the viral gH/gL complex. Although crystal structures of the gB ectodomain of several herpesviruses have been reported, the membrane fusion mechanism has remained elusive. Here, we report the X-ray structure of the Pseudorabies virus (PrV) gB ectodomain, revealing a typical class III post-fusion trimer that binds membranes via its fusion loops (FLs) in a cholesterol-dependent manner...

Influenza B virus causes considerable disease burden worldwide annually, highlighting the limitations of current influenza vaccines and antiviral drugs. In recent years, broadly neutralizing antibodies (bnAbs) against hemagglutinin (HA) have emerged as a new approach for combating influenza. We describe the generation and characterization of a chimeric monoclonal antibody, C12G6, that cross-neutralizes representative viruses spanning the 76 years of influenza B antigenic evolution since 1940, including viruses belonging to the Yamagata, Victoria, and earlier lineages...

Enveloped viruses transfer their genomes into host cells by fusing their membrane to that of the cell. To visualize single-virus fusion in living cells, researchers take advantage of HIV-1's proteolytic maturation, which can generate free fluorescent proteins within the viral particle. Co-labeling viruses with a content marker and a fluorescently tagged Vpr (a viral core protein) enables detection of single-virus fusions, but a major limitation of this approach is that not all viral particles incorporate both markers...

Vaccine against HIV-1 is not currently available. In present, Virus like particles (VLPs) as effective strategy was used in several vaccine developing. Two conserved sequences; V3 loop of gp120 and the membrane-proximal external region (MPER) of gp41 are dominant sites for vaccine studies. In this study, we used fusion gene of MPER and V3 to product recombinant VLPs and introduced a novel retroviral VLPs harboring high copy of MPER-V3 for HIV-1 vaccine design. The pEGFP-N1 plasmid harboring MPER-V3 sequence with Vpr linker was constructed...
