Identification of SERPINE1 as a Regulator of Glioblastoma Cell Dispersal via Analyzing Dynamic Transcriptome of Dispersing Cells

With a model mimicking GBM tumor cell dispersal, transcriptome changes between core (immotile) and dispersive (motile) cells were analyzed. Many genes are differentially expressed between these populations. This study focused on the genes that are significantly upregulated in dispersive cells. Besides gene sets related with the cell cycle and cell survival, epithelial to mesenchymal transition gene set is upregulated in dispersive cells. In this gene set, this study identified SERPINE1 gene as an important regulator of GBM cell dispersal. Examination of core and dispersive populations' transcriptome during U373 cell spheroid dispersal. 2 sets of samples were prepared each for core and dispersive cells.
