Hypoxia activates heparanase expression in an NF-kappaB dependent manner.


Hypoxia was shown to increase tumor cell invasion into the extracellular matrix in vitro. This result suggests that heparanase (Hpa), one of the key enzymes involved in tumor invasion and metastasis, may be regulated by hypoxia. RT-PCR, Western blot and Matrigel invasive assays were used to study the regulation of Hpa under hypoxia in human pancreatic MIA… (More)
