[glycobiology and extracellular matrices] heparanase stimulation of protease expression implicates it as a master regulator of the aggressive tumor phenotype in myeloma

November 19th, 2008 by admin

High levels of heparanase are an indicator of slummy forecasting in myeloma patients, and up-regulation of the enzyme enhances ontogeny growth, angiogenesis, and metastasis in birdlike models. At small conception of the gist of heparanase in dynamical the battleful ontogeny phenotype is cod to its gist on crescendo the countenance and sloughing of the heparan salt proteoglycan syndecan-1, a mote famous to encourage myeloma progression. The inform impact demonstrated that rising in heparanase countenance in myeloma cells stimulates uninterrupted ERK phosphorylation that in invoke drives MMP-9 expression. In addition, urokinase-type plasminogen activator (uPA) and uPA organ countenance levels increased, and interference the proteolytic activation of either MMP-9 or uPA smothered the heparanase-induced increase…
