Expression and Clinical Significance of bcl-X_L mRNA and Its Protein in Childhood Medulloblastoma / 实用儿科临床杂志

ABSTRACT

Objective To study the expression level and clinical significance of bcl-XL gene in childhood medulloblastoma.Methods The expression of Bcl-XL protein and bcl-XL mRNA were determined by immunohistochemical staining and in situ hybridization in 41 samples of medulloblastoma tissues,as well as 20 normal brain tissues.Results The positive rate of Bcl-XL protein(90.2%) and bclXL mRNA(95.1%) in medulloblastoma group were significantly higher than those in normal human brain tissues(all P
