FIGURE 4.

Expression of PTN or ALK in brain tumors in patients with different survival. Data from the Oncomine data base showing the expression levels of PTN (Phillips et al., 2006) or of ALK (Shai et al., 2003) in brain tumor samples. Tumor expression data were separated into those from patients alive or dead at 5 years (PTN) or 3 years (ALK) respectively. The data are presented as log values after normalization to the respective gene expression array and are shown as provided by Oncomine. Further studies are provided in Tables 1 and 2.
