Sphingolipids are found in abundance at synapses and have been implicated in regulation of synapse structure, function and degeneration. Their precise role in these processes, however, remains obscure. Serine Palmitoyl-transferase (SPT) is the first enzymatic step for synthesis of sphingolipids. Analysis of the Drosophila larval neuromuscular junction revealed mutations in the SPT enzyme subunit, lace/SPTLC2 resulted in deficits in synaptic structure and function. Although neuromuscular junction (NMJ) length is normal in lace mutants, the number of boutons per NMJ is reduced to ∼50% of the wild type number...

BACKGROUND: Recently, basigin (BSG), which carries OK antigens on red blood cells (RBCs), was reported to be the receptor of the Plasmodium falciparum reticulocyte-binding protein homolog 5 (PfRh5). BSG-PfRh5 is the only essential receptor-ligand pair in P. falciparum invasion that is known to date. However, the kind of OK/BSG polymorphism involved in the selection pressure caused by P. falciparum malaria has not been determined. STUDY DESIGN AND METHODS: Blood samples were collected to detect the expression of OK/BSG...

Multiple myeloma (MM) is a haematologic malignancy characterized by the presence of atypical plasma cells. Basigin (BSG, CD147) controls lactate export through the monocarboxylic acid transporter 1 (MCT1, SLC16A1) and supports MM survival and proliferation. Additionally, BSG is implicated in response to treatment with immunomodulatory drugs (thalidomide and its derivatives). We investigated the role of single nucleotide polymorphisms (SNPs) in the gene coding for BSG and SLC16A1 in MM. Following an in silico analysis, eight SNPs (four in BSG and four in SLC16A1 ) predicted to have a functional effect were selected and analyzed in 135 MM patients and 135 healthy individuals...

The retinal Müller glial cells, like other types of glial cells, can enhance the survival and activity of neurons, especially of retinal ganglion cells (RGCs), which are the neurons affected in diseases such as glaucoma, diabetes and retinal ischemia. It has been demonstrated that Müller glia release neurotrophic factors that support RGC survival, yet many of these factors remain to be elucidated. To define these neurotrophic factors, we adopted a quantitative proteomic approach aiming at identifying neuroprotective proteins...

CD147, encoded by BSG , is a highly glycosylated transmembrane protein that belongs to the immunological superfamily and expressed on the surface of many types of cancer cells. While CD147 is best known as a potent inducer of extracellular matrix metalloproteinases, it can also function as a key mediator of inflammatory and immune responses. To systematically elucidate the function of CD147 in cancer cells, we performed an analysis of genome-wide profiling across the Cancer Cell Line Encyclopedia (CCLE). We showed that CD147 mRNA expression was much higher than that of most other genes in cancer cell lines...

In this work, the GAA (Gate All Around) L-Shaped bottom select transistor (BSG) in 3D NAND Flash Memory has been investigated. Different methods are proposed to optimize its performance from viewpoints of process and structure. BSG in 3D NAND is a novel device structure with two connected transistors: one is horizontal MOSFET (regarded as convention MOSFET) and one is vertical MOSFET (regarded as GAA transistor). With implant dose increasing in vertical channel, BSG Vth has much more tighter Vt distribution, which is beneficial for boosting potential improvement and program disturbance suppression...

We established the KU-Lu-8 monoclonal antibody (MoAb) using a lung cancer cell line as an antigen and a random immunization method. The KU-Lu-8 MoAb recognizes basigin (BSG), which is a transmembrane-type glycoprotein that is strongly expressed on the cell membranes of lung cancer cells. This study aimed to clarify the relationships between BSG expression and clinicopathological parameters and determine the prognostic significance of BSG expression in pulmonary adenocarcinoma (AC) patients. To evaluate the significance of BSG expression in lung cancer, we immunohistochemically analyzed 113 surgically resected pulmonary adenocarcinomas, and the associations between BSG expression and various clinicopathological parameters were evaluated...

Brewer's spent grain (BSG) accounts for around 85% of the solid by-products from beer production. BSG was first extracted to obtain water-soluble arabinoxylan (AX). Using subsequent alkali extraction (0.5 M KOH) it was possible to dissolve additional AX. In total, about 57% of the AX in BSG was extracted with the purity of 45-55%. After comparison of nine xylanases, Pentopan mono BG, a GH11 enzyme, was selected for hydrolysis of the extracts to oligosaccharides with minimal formation of monosaccharides. Growth of Bifidobacterium adolescentis (ATCC 15703) was promoted by the enzymatic hydrolysis to arabinoxylooligosaccharides, while Lactobacillus brevis (DSMZ 1264) utilized only unsubstituted xylooligosaccharides...
