Genomic aberrations in pediatric diffuse intrinsic pontine gliomas.
Diagnostic biopsy is not routinely performed for children with diffuse intrinsic pontine glioma (DIPG). Consequently, our understanding of DIPG biology is hindered by limited tissue availability. We performed comparative genomic hybridization (CGH) on autopsy specimens to examine the feasibility of determining DNA genomic copy number aberrations on formalin-fixed, paraffin-embedded (FFPE) block...
متن کاملDiffuse intrinsic pontine gliomas: treatments and controversies.
Diffuse intrinsic pontine gliomas (DIPGs) are a fairly common pediatric brain tumor, and children with these tumors have a dismal prognosis. They generally are diagnosed within the first decade of life, and due to their location within the pons, these tumors are not surgically resectable. The median survival for children with DIPGs is less than 1 year, in spite of decades of clinical trial deve...
متن کاملRe-Examining the Need for Tissue Diagnosis in Pediatric Diffuse Intrinsic Pontine Gliomas: A Review
Diffuse intrinsic pontine glioma (DIPG) is a malignant brain tumor of childhood that carries an extremely poor prognosis. There are ~200-300 new cases diagnosed each year, [1, 2] and little progress has been made in changing the prognosis and outcome of the tumor since it was first documented in the literature in 1926 [3]. The median overall survival is 8-11 months [4], with an overall survival...
متن کاملPatient-derived Tumor Models for Diffuse Intrinsic Pontine Gliomas
BACKGROUND Diffuse intrinsic pontine gliomas represent a unique subtype of primary brain tumors occuring in a specific location and age. Their growth demonstrates early invasion and, following diagnosis, rapid growth not responsive to common therapies. Until recently, the genetic and cellular basis of these tumors was unknown. Genetic evidence implicates mutations in the histone genes in the or...
متن کاملAltered Expression of Epidermal Growth Factor Receptor (EGFR) in Glioma
EGFR is a key molecule in cancer cells. EGFR signaling was shown to promote tumor cell proliferation and survival, invasion and angiogenesis and mediate resistance to treatment, including ionizing radiation in preclinical models. We extracted proteins from astrocytoma (III and IV) oligodendroglioma(IV) tumors and normal brain tissues and then evaluated the protein purity by Bradford test ...
