Protein kinase B (PKB) is involved in signaling to a multitude of important cellular events and is activated by insulin and growth factors, including insulin-like growth factor I (IGF-I). We show here expression of PKB in pancreatic islets and in the beta cell lines HIT-T15, INS-1, and RINm5F. Expression of PKB mRNA and the presence of PKB isoforms (alpha, beta, and gamma) were assessed by Norther
Neuroblastoma is an embryonal tumour of the peripheral sympathetic nervous system (SNS). One of the master regulator genes for peripheral SNS differentiation, the homeobox transcription factor PHOX2B, is mutated in familiar and sporadic neuroblastomas. Here we report that inducible expression of PHOX2B in the neuroblastoma cell line SJNB-8 down-regulates MSX1, a homeobox gene important for embryon
OBJECTIVE AND STUDY DESIGN: We report for the first time an inhibitory effect on cell division and germ tube formation by Candida albicans and strains of other Candida species by putrescine and cadaverine. RESULTS: Both bacterial amines showed a dose-dependent inhibition of germ tube formation by C albicans, as well as budding (inhibition of cell division) of strains of other Candida species (ie,
OBJECTIVE To investigate the mechanisms involved in the phasic contractile activity after muscarinic receptor activation of newborn urinary bladders and to compare neonatal and adult bladders. MATERIALS AND METHODS Detrusor muscle strips were isolated from newborn mice (aged 0-2 days) and compared with preparations from adult mice (aged 10-12 weeks). The effects of an activator (phorbol 12,13-dibu
Eight cytogenetically characterized head and neck squamous cell carcinomas (HNSCCs) with CCND1 amplification in the form of a homogeneously staining region (hsr) in 11q13 were studied by COBRA FISH and FISH with specific probes to identify and characterize chromosomal segments added to the derivative chromosomes 11. In 4 of the tumors, it could be recognized that the material added was derived fro
Human neutrophils have an important role in host defense against microbial infection. At different stages of an infectious process, neutrophils progressively up-regulate receptors and release various effector molecules. These are stored in several distinct types of granules with varying propensity to be secreted. Heparin-binding protein (HBP), also known as CAP37 or azurocidin, is a multifunctiona
Aims. The glycosphingolipid beta-galactosylceramide-3-O-sulfate (sulfatide) is present in the secretory granules of the insulin producing beta-cells and may act as a molecular chaperone of insulin. The final step in sulfatide synthesis is performed by cerebroside sulfotransferase (CST) (EC 2.8.2.11). The aim of this study was to investigate whether two single nucleotide polymorphisms (SNP), rs2267
Neutrophilic granulocytes contain the 55 kDa bactericidal/permeability-increasing protein (BPI). BPI binds to lipopolysaccharides (LPS), and exerts bacteriostatic and bactericidal effects against a wide variety of Gram-negative bacterial species. We have investigated the subcellular location of BPI in immature and mature neutrophils using cryotechnique for immunoelectron microscopy. BPI was found
Objective: Fibroblast growth factor-23 (FGF23) is a circulating factor involved in phosphate (Pi) and vitamin D metabolism. Serum FGF23 is increased at later stages of chronic kidney disease due to chronic hyperphosphatemia and decreased renal clearance. Recent studies also indicate that FGF23 may directly regulate the expression of parathyroid hormone (PTH) in vitro. Therefore, the objective of t
Matrilin-2 is a member of the protein superfamily with von Willebrand factor type A-like modules. Mouse matrilin-2 cDNA fragments were expressed in 293-EBNA cells, and the protein was purified, characterized, and used to immunize rabbits. The affinity-purified antiserum detects matrilin-2 in dense and loose connective tissue structures, subepithelial connective tissue of the skin and digestive tra
The purpose of this study is to investigate the use of corpus linguistics, with a specific focus on the concordances in teaching and learning English in Vietnam. The concordance samples provide teachers and students with the information about the different patterns of use and structure that can be found for each word. I have designed a new kind of linguistics exercises on the basic of the selected
Popular Abstract in Swedish Strålbehandling har sedan länge visat sig vara en bra metod för att behandla patienter med cancer. Den nya teknik som har introducerats under de senaste åren har möjliggjort ökade stråldoser till än mer begränsade volymer. Samtidigt innebär detta att ökade krav ställs på att man försäkrar sig om att den volym man bestrålar är den volym som innehåller tumörceller och attMethods for ensuring that the intended volume receives the intended absorbed dose in radiotherapy have been investigated. In order to optimise radiation treatment of cancer, geometric variations in the treatment chain need to be controlled. Furthermore, hazards potentially leading to unintended irradiation need to be controlled. While the required methods for optimisation of irradiation are divers
