one of the main members of the large aggregating proteoglycans (pgs) family is versican which is able to bind to hyaluronate. versican is a chondroitin sulfate proteoglycan and is a key ingredient of the extracellular matrix. due to its widespread expression in the body, versican is involved in cell adhesion, proliferation and migration. induced expression of versican is often observed in tiss...
background: to develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. in this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: trichophyton rubrum, trichophyton mentagrophytes and microsporum canis. methods: clinical ...
AIMS The objectives of this work were to determine the extracellular enzyme profiles during composting, relate the activities of these enzymes to the changes in microbial population and compare the enzyme profiles between two manures. METHODS AND RESULTS API ZYM assay was used to monitor the activities of 19 extracellular enzymes during poultry and pig manure composting. Results showed an ove...
Exosomes derived from mesenchymal stem cells (MSC-Exos) are nano-sized extracellular vesicles enriched with bioactive molecules, such as microRNAs, enzymes, cytokines, chemokines, immunomodulatory, trophic, and growth factors. These molecules regulate the survival, phenotype, function of malignant tumor-infiltrated immune cells. Due to their nano-size bilayer lipid envelope, MSC-Exos can easily...
The production of invertases by anamorph (A. nidulans) and teleomorph (E. nidulans) was investigated. The best level of extracellular enzymatic production for anomorph was obtained in Khanna medium containing sucrose as carbon source, whereas for teleomorph the best production was archived using M5 medium containing inulin as carbon source. Despite this, rye flour was selected as carbon source....
Fertilization is accompanied by the construction of an extracellular matrix that protects the new zygote. In sea urchins, this structure is built from glycoproteins residing at the egg surface and in secretory vesicles at the egg cortex. Four enzymatic activities are required for the transformation of these proteins into the mechanically and chemically resilient fertilization envelope: proteoly...
Department of Microbiology, University of Leeds, Leeds LS2 9JT, UK Incubation of Aspergillus fumigatus NCPF 2140 in growth medium containing 1 O/ O chitin as sole carbon source led to induction of specific extracellular chitinolytic activity of 1-5 pmol GlcNAc released min'l (mg protein)'l. The effect was repressed by the inclusion of GlcNAc in the medium, indicating regulation by a negative fe...
Extracellular factors that inhibit axon growth and intrinsic factors that promote it affect neural regeneration. Therapies targeting any single gene have not yet simultaneously optimized both types of factors. Chondroitin sulphate (CS), a glycosaminoglycan, is the most abundant extracellular inhibitor of axon growth. Here we show that mice carrying a gene knockout for CS N-acetylgalactosaminylt...
Transglutaminase (TG) is a big class of intraand extracellular enzymes with 9 members, all of which catalyze the formation of epsilon(γ-glutamyl) lysine isopeptide linkages between peptide substrates, except for a catalytically inactive member Band 4.1. These enzymes are tightly regulated, and involved in processes such as inflammation, reepithelialization, neovascularization and synthesis and ...
