MS-1, a high-molecular-mass protein expressed by non-continuous and angiogenic endothelial cells and by alternatively activated macrophages (Mphi2), and the hepatic sinusoidal endothelial hyaluronan clearance receptor are similar with respect to tissue distribution and biochemical characteristics. In the present study we purified these proteins by immuno- and hyaluronan-affinity chromatography ...
Microenvironmental interactions are crucial for the survival and proliferation of chronic lymphocytic leukemia (CLL) cells. CD4+ T cells that express CD40 ligand (CD40L), along with other accessory immune and stromal cells within CLL lymph nodes, provide signals needed for activation and outgrowth of the tumor clone. Furthermore, correct positioning of CLL cells within lymphoid subcompartments ...
Vascular endothelial cells are shielded from direct exposure to flowing blood by the endothelial glycocalyx, a highly hydrated mesh of glycoproteins, sulfated proteoglycans, and associated glycosaminoglycans (GAGs). Recent data indicate that the incorporation of the unsulfated GAG hyaluronan into the endothelial glycocalyx is essential to maintain its permeability barrier properties, and we hyp...
Nuchal skin oedema at 10-14 weeks gestation, observed by ultrasonography as increased nuchal translucency (NT), is found in approximately 70% of fetuses with trisomies 21, 18 and 13 as well as those with Turner's syndrome. This study investigates the possibility that one mechanism for increased translucency is an altered composition of the skin with a higher concentration of hyaluronan; large a...
Hyaluronan is related to essential reproductive processes in pigs. Hyaluronan produced by cumulus cells builds, via specific cell surface receptors, an extracellular matrix responsible for cumulus cell cloud expansion during final oocyte maturation, a preparatory event for ovulation and fertilization. In addition, hyaluronan that has been localized in the pig oviduct both in the intraluminal fl...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
The high-molecular-mass polysaccharide hyaluronan is abundant in the extracellular space between adjacent keratinocytes throughout the vital part of epidermis. It has a rapid turnover, and its content is subject to large fluctuations due to physiological and environmental conditions, with the strongest effects mediated by EGFR signaling. Using an elegant organotypic culture system, Monslow et a...
We have identified two discrete hyaluronan- (HA) binding domains in the HA receptor RHAMM (Receptor for HA-Mediated Motility) that mediates the locomotion of H-ras transformed fibroblasts. A complete RHAMM cDNA (1.43 kilobases (kb)) was expressed as a fusion protein with pGEX-2T in Escherichia coli HB101 and was shown to bind specifically to both biotin-labeled HA in a transblot assay and to HA...
