Relationship between the expression of PTEN mRNA and protein in human brain glioma / 西安交通大学学报(医学版)

Objective To explore the clinical significance of the differential expression of PTEN in glioma tissue.Methods The mRNA and protein expressions of PTEN were assayed by reverse transcription polymerase chain reaction(RT-PCR) and immunohistochemistry in 75 human brain glioma cases.Results The positive expression rate mRNA of PTEN differed significantly between brain glioma tissue and normal brain tissue(?2=22.66,P
