Expression of the hypoxia-induced genes OPN, CA9, EPO, VEGF and HIF-1alpha was analyzed in three GBM cell lines, GaMG, U373 and U251, under in vitro hypoxia (1, 6 or 24h at 5%, 1% or 0.1% O(2)) and in tumor samples from two patient groups with LGA and GBM (n=15 each), at the mRNA level (semiquantitative RT-PCR).
