Rtner and regulator of KSR1 and the MAPK pathway.One of the main functions of the scaffold protein CNKSR1 is the regulation of other cancer-related signaling pathways integrating output to different intracellular signaling cascades upon cellular stimulation by extracellular cues [11, 12, 17?0]. In breast and cervical cancer cell models, a pro-oncogenic potential has been demonstrated through ERK-i

Of each cell colony over 24 hours was calculated. Data for each cell line was averaged over 10 wells and compared between parental, control transfected, and galectin-1 transfected cells. A t-test was applied to compare means.In vitro invasion assay6.8 pg +/- 4.2 pg. In spite of this variability, the quality of the RNA was consistently high with a mean RNA integrity number of 8.13 ?0.74. Expression

The column-based PicoPure RNA isolation kit (Arcturus, Mountain View, CA) was used to extract RNA from collected cells per manufacturer instructions.Toussaint et al.

Galectin-1 transfectants. A population of GFP-sorted cells (the "Gal-1" bars in Figure 4A) was compared to its parental counterpart. The number of metabolically-active cells attached to fibronectin was no different between the two lines at eight hours. Changing the media at four hours reduced the number of cells left for labeling, but the effect was equal in both groups, suggesting a similar rate

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

By the ample amount of normal mouse brain tissue available for dissection. In spite of species differences, cross-hybridization of mouse genetic material to human probes did prove to be a common occurrence. These data made it possible to control, rather stringently, for the potential contamination of tumor edge samples with mouse brain. Of course, there could still be possible contamination ?react

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

Time intervals in a time-dependent experiment. Expression and phosphorylation of ERK (Thr-202/Tyr204) and MEK-1 (Ser-217/221) was determined by western blotting. B) The effect of Triphala on the kinase activity of ERK was determined using a kit from Cell Signaling Technology, measuring the phosphorylation of Elk-1 at Ser-383. C, D) Effect of ERK inhibitor on Triphala induced apoptosis and activati
