PAF-AH and PLA2R transcripts in human meningiomas. Upper panel: plasma PAF-AH (PLA2-VIIA) and intracellular PAF-AH (PLA2-VIIB) in meningioma tumors. Fifteen-grade I and nine-grade II+III meningiomas were investigated. () indicates patients with no detectable transcript. No significant differences were documented between groups. Lower panel: PLA2R transcripts in fifteen-grade I and nine-grade II+III meningiomas.
