From: GAPDH is not regulated in human glioblastoma under hypoxic conditions
HIF-1α mRNA expression in vivo in different human brain tissues, detected by semi-quantitative RT- PCR. HIF-1α mRNA expression was comparable in normal brain (NB), low-grade astrocytoma and glioblastoma. + = positive control using genomic DNA as template, - = negative control with water as template. The bar graphs show band intensities after densitometric evaluation and normalization of HIF-1α expression to the corresponding β-actin expression.
