ABSTRACT
We studied the peculiarity of the expression of several key genes related to dysregulation of cell proliferation and surviving processes in pediatric glioma (glioblastoma multiforme) tissue from five children with age from 5 to 8 years as well a sin corresponding nonmalignant tissue counterparts as control from the same patients. RNA was isolated from glioma tissue and corresponding non-malignant tissue counterparts and PFKFB1, PFKFB2, PFKFB3, PFKFB4, HK2, NAMPT, TSPAN13, and HSPB8 gene expressions were studied by quantitative polymerase chain reaction. It was shown that the expression level of genes PFKFB1, PFKFB2, PFKFB3, PFKFB4, HK2, NAMPT, TSPAN13, and HSPB8 is increased in pediatric gliomas as compared to corresponding non-malignant tissue counterparts, but in different grade. More significant changes were demonstrated for PFKFB3, PFKFB4 HK2, NAMPT, TSPAN13, and HSPB8 genes. Thus, the changes in pediatric glioma tissues of the expression of PFKFB1, PFKFB2, PFKFB3, PFKFB4, HK2, NAMPT, TSPAN13, and HSPB8 genes, which control cell proliferation and apoptosis, possibly contribute to enhance the tumor growth, because these genes control cell proliferation and surviving.
