1.	Caglayan, Demet, et al. (author) Induction of Glioblastoma Multiforme and Gliomatosis Cerebri with a Sleeping Beauty gene transfer system, implications for T regulatory cell involvement during glioma formation. Other publication (other academic/artistic)abstract Glioblastoma Multiforme (GBM), the most malignant and common neoplasm of the central nervous system (CNS), has been classified into subgroups with gene-expression profile as the basis for categorization. Among these the mesenchymal subgroup is most greatly associated with inflammatory infiltrates and increased expression of inflammatory associated genes. GBMs exhibit T cell infiltration to a varying degree and today the degree of infiltration is not used in prognostics. The Sleeping Beauty (SB) system was used to introduce AKT, a mutant variant of NRAS and a shp53 coupled to green fluorescent protein (GFP) into mice that are fully immunocomptetent, lack mature T cells or have reduced regulatory T (Treg) cell function respectively. We report, for the first time, the induction of Gliomatosis Cerebri with the SB system. Tumors that originated were either GBM or Gliomatosis Cerebri with a similar incidence. There was no difference in survival, grade or incidence of induced tumors in wild type mice and mice that lack mature T cells.
