Expression of CD74 mRNA in 4 GBM xenograft lines relative to temozolomide sensitivity. A) The heat-map results of a microarray analysis of the CD74 probe set for the TMZ sensitive (GBM12 and GBM14) and TMZ resistant (GBM43 and GBM44) lines are shown. B) Total RNA from the same lines were reverse transcribed and PCR amplified using primers specific for human CD74 (upper panel). Beta-actin was used as internal control (lower panel)
