ABSTRACT Tumour angiogenesis is a vital process in the pathology of tumour development and metastasis. Targeting markers of tumour endothelium provide a means of targeted destruction of a tumours oxygen and nutrient supply via destruction of tumour vasculature, which in turn ultimately leads to beneficial consequences to patients. Although current anti -angiogenic and vascular targeting strategies help patients, more potently in combination with chemo therapy, there is still a need for more tumour endothelial marker discoveries as current treatments have cardiovascular and other side effects. For the first time, the analyses of in-vivo biotinylation of an embryonic system is performed to obtain putative vascular targets. Also for the first time, deep sequencing is applied to freshly isolated tumour and normal endothelial cells from lung, colon and bladder tissues for the identification of pan-vascular-targets. Integration of the proteomic, deep sequencing, public cDNA libraries and microarrays, delivers 5,892 putative vascular targets to the science community. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

In this respect, it regulates pivotal cell surface events, including trans-membrane signaling, and plays an essential role in carcinogenesis. In this report, we demonstrated that acute lymphoblastic leukemia (ALL), lymphoblasts (primary cells from patients and cell lines) are characterized by a marked down-regulation of Neu3 in terms of both gene expression (230 to 40%) and enzymatic activity toward ganglioside GD1a (225.6 to 30.6%), when compared with cells from healthy controls. Induced overexpression of Neu3 in the ALL-cell line, MOLT-4, led to a significant increase of ceramide (166%) and to a parallel decrease of lactosylceramide (255%). These events strongly guided lymphoblasts to apoptosis, as we assessed by the decrease in Bcl2/ Bax ratio, the accumulation of Neu3 transfected cells in the sub G0–G1 phase of the cell cycle, the enhanced annexin-V positivity, the higher cleavage of procaspase-3. -

Received: 6 July 2020; Accepted: 7 August 2020; Published: 27 August 2020 Abstract: GM2 gangliosidoses are a group of pathologies characterized by GM2 ganglioside accumulation into the lysosome due to mutations on the genes encoding for the β-hexosaminidases subunits or the GM2 activator protein. Three GM2 gangliosidoses have been described: Tay–Sachs disease, Sandhoff disease, and the AB variant. Central nervous system dysfunction is the main characteristic of GM2 gangliosidoses patients that include neurodevelopment alterations, neuroinflammation, and neuronal apoptosis. Currently, there is not approved therapy for GM2 gangliosidoses, but different therapeutic strategies have been studied including hematopoietic stem cell transplantation, enzyme replacement therapy, substrate reduction therapy, pharmacological chaperones, and gene therapy. -

Weimer1 Complex glycans cover the gut epithelial surface to protect the cell from the environment. Invasive pathogens must breach the glycan layer before initiating infection. While glycan degradation is crucial for infection, this process is inadequately understood. Salmonella contains 47 glycosyl hydrolases (GHs) that may degrade the glycan. We hypothesized that keystone genes from the entire GH complement of Salmonella are required to degrade glycans to change infection. This study determined that GHs recognize the terminal monosaccharides (N-acetylneuraminic acid (Neu5Ac), galactose, mannose, and fucose) and significantly (p < 0.05) alter infection. During infection, Salmonella used its two GHs sialidase nanH and amylase malS for internalization by targeting different glycan structures. The host glycans were altered during Salmonella association via the induction of N-glycan biosynthesis pathways leading to modification of host glycans by increasing fucosylation and mannose content, while decreasing sialylation. -

Molecular Mechanisms Regulating Copper Balance in Human Cells
MOLECULAR MECHANISMS REGULATING COPPER BALANCE IN HUMAN CELLS by Nesrin M. Hasan A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland August 2014 ©2014 Nesrin M. Hasan All Rights Reserved Intended to be blank ii ABSTRACT Precise copper balance is essential for normal growth, differentiation, and function of human cells. Loss of copper homeostasis is associated with heart hypertrophy, liver failure, neuronal de-myelination and other pathologies. The copper-transporting ATPases ATP7A and ATP7B maintain cellular copper homeostasis. In response to copper elevation, they traffic from the trans-Golgi network (TGN) to vesicles where they sequester excess copper for further export. The mechanisms regulating activity and trafficking of ATP7A/7B are not well understood. Our studies focused on determining the role of kinase-mediated phosphorylation in copper induced trafficking of ATP7B, and identifying and characterizing novel regulators of ATP7A. We have shown that Ser- 340/341 region of ATP7B plays an important role in interactions between the N-terminus and the nucleotide-binding domain and that mutations in these residues result in vesicular localization of the protein independent of the intracellular copper levels. We have determined that structural changes that alter the inter-domain interactions initiate exit of ATP7B from the TGN and that the role of copper-induced kinase-mediated hyperphosphorylation might be to maintain an open interface between the domains of ATP7B. In a separate study, seven proteins were identified, which upon knockdown result in increased intracellular copper levels. We performed an initial characterization of the knock-downs and obtained intriguing results indicating that these proteins regulate ATP7A protein levels, post-translational modifications, and copper-dependent trafficking. -

Abstract: Altered sialylation patterns play a role in chronic autoimmune diseases such as rheumatoid arthritis (RA). Recent studies have shown the pro-inflammatory activities of immunoglobulins (Igs) with desialylated sugar moieties. The role of neuraminidases (NEUs), enzymes which are responsible for the cleavage of terminal sialic acids (SA) from sialoglycoconjugates, is not fully understood in RA. We investigated the impact of zanamivir, an inhibitor of the influenza virus neuraminidase, and mammalian NEU2/3 on clinical outcomes in experimental arthritides studies. The severity of arthritis was monitored and IgG titers were measured by ELISA. (2,6)-linked SA was determined on IgG by ELISA and on cell surfaces by flow cytometry.
