Project description:Glioblastoma multiforme (GBM) is a highly aggressive and vascularized malignant brain tumor. SoxF transcription factors consisting of Sox7, Sox17, and Sox18 are expressed specifically in endothelial cells (ECs) and contribute to vascular morphogenesis. While the role of Sox17 was found in subcutaneous ectopic tumors, Sox7 has not been studied in the context of tumor angiogenesis. Here, we investigated gene expression profile of RNA analysis of Sox7- and Sox17-deficient mouse endothelial cells from high grade glioma using RNA sequencing to validate molecular characteristics of Sox7 and Sox17 in high grade glioma.
Project description:Analysis of the expression of F9 cells after knockdown of Sox7 and Sox17 during their primitive endoderm differnetiation induction with retinoic acid. Results provide information on the endodermal gene expression program regulated by Sox7 and Sox17. Sox7 Sox17 double KD vs. control in F9 cells
Project description:This study aimed to understand the transcriptional networks regulating endoderm specification from HESC and therefore explored the phenotype of CA1 and CA2 HESC constitutively over-expressing SOX7 or SOX17. Cell lines were created using an inducible construct whereby clonal populations containing transgene integration are selected by Neomycin resistance without expressing of the gene of interest (NoCre controls). Transgene expression is induced via Cre-mediated recombination and selected for puromycin resistance (SOX O/E). The phenotype of the resulting cells suggests that SOX7 expressing HESC represent stable extraembryonic endoderm progenitors, while SOX17 expressing HESC represent early definitive endoderm progenitors. Both in vitro and in vivo SOX7 expressing HESC are restricted to the extraembryonic endoderm lineage, while SOX17 expressing HESC demonstrate mesendodermal specificity. In vitro, SOX17 expressing HESC efficiently produce mature definitive endoderm derivatives. The molecular phenotype of the resulting SOX7 and SOX17 expressing HESC was characterized by microarray analysis Experiment Overall Design: Total RNA was extracted from confluent monolayer cultures of SOX7 over-expressing HESC, SOX17 over-expressing HESC, and their respective control parental HESC lines (designated NoCre Sox7 and NoCre Sox17).

Project description:To find out the target of transcription factor Sox7 and Sox17, DNA microarray analysis was performed with RNA from Sox7 and Sox17 knockdown HUVECs.
