The expressions and their relationship of PTTG,P27 and CDK4 in glioma / 中国基层医药

ABSTRACT

Objective To investigate the role of expressions of pituitary tumor transforming gene(PTTG) and p27 in glioma,and explore the relationship between the expressions of them and cell cycle regulation.Methods Specimens of 40 patient with gliomas were divided into gradeⅠ8 cases,gradeⅡ10 cases,gradeⅢ13 cases, gradeⅣ9 cases,PTTGmRNA and p27mRNA were detected by reverse transcription polymerase chain reaction (RT-PCR),and their expressions of PTTG,P27,CDK4 protein were detected by immunostaining assay using strep- tavidin-peroxidase(SP) method.Results The expressions of PTTGmRNA in gradeⅠ～Ⅳwere (0.907?0.065),(1.109?0.083),(1.312?0.089),(1.499?0.215) respectively,there was significant difference among the groups(P
