Figure 2From: Galectin-1, a gene preferentially expressed at the tumor margin, promotes glioblastoma cell invasionThe galectin-1 expression profile fits the criteria for a gene candidate that is relatively over-expressed at the tumor periphery. These graphical representations of gene expression data compare the relative expression of galectin-1 from the core and edge of tumors to pooled data from normal mouse brain samples.
