Assays of GBM cells stably transfected to over-express galectin-1, perfectly fit in with the previous studies mentioned above and highlight the importance of galectin-1 in the biologically aggressive behavior of experimental GBMs. While there was no enhancement of proliferation or change inattachment to fibronectin, galectin-1 upregulation induced more rapid two-dimensional migration and enhanced

Ed by the current ones, highlight a major role for galectin-1 in GBM invasiveness. The characteristic malignant phenotype of glioblastoma extends beyond aggressive invasion. This tumor develops resistance to chemo- and radio-therapy, it promotes neoangiogenesis, and it seems to benefit from immune privilege. Interestingly, galectin-1 may play a role in promoting each of these phenotypes. While gal

Survival curves were generated from those animals (38 of 40) developing tumors (7 of 20 acGFP-only).xenograft lines is necessary to characterize completely the in vivo phenotypic alterations that accompany overexpression of galectin-1.Our model system has identified galectin-1 as a ma

Action of the tumor [22,36]. Indeed, abrogating galectin-1 expression renders tumor cells more susceptible to temozolamide treatment [22,41]. Finally, galectin-1 induces apoptosis of activated T-cells [42-46], prevents host animals from mounting tumor vaccine-induced immunity [47], and may cooperate with TGF-beta in GBM-induced immunosuppression [48,49]. In sum, galectin-1 expression may inversely

Radial migration assay was performed as previously described [30,31]. In a blinded fashion, various U87Gal-1 clones were analyzed and compared to U87GFP controls and parental U87MG cells. Of each clone, 2500 cells were allowed to sediment through a cooled manifold onto laminin-coated cell culture wells (Creative Scientific Methods, Inc., Phoenix, AZ). The manifold and slide were incubated together
