Cal significance.Paraffin sections of our patient-derived glioblastoma xenografts (15 of 22 lines) were stained for galectin-1 expression. Around half of the xenografts tested showed preferential staining at the tumor-brain interface (Figure 3). A few tumors stained in their entirety, and another subset lacked significant staining. The 2 to 4 fold change in galectin-1 mRNA expression at the tumor

Activation of ERK with induction of apoptosis by various chemopreventive and chemotherapeutic agents [39-41]. In fact, oxidants have been shown to activate ERK by taking over the growth factor receptor signaling pathways [42-46]. Moreover, ERK may get activated in response to DNA damage and can phosphorylate p53 in vitro [23,24,47-49]. We found that exposure of Capan-2 or BxPC-3 cells with apoptos

Ioblastoma in general. In conclusion, the orthotopic glioblastoma xenograft model recapitulates not only the invasive phenotype, but also the regional expression profile reported in human samples of glioblastoma multiforme. The value of the model (i.e., abundant tissue, high-quality RNA, andToussaint et al. Molecular Cancer 2012, 11:32 http://www.molecular-cancer.com/content/11/1/Page 10 ofFigure
