Table 1. CSF1 and IL-34 expression changes in human GBM and AA compared to normal brain in datasets in www.oncomine.org.

CSF1 is up-regulated significantly in GBMs or AAs in 4 of 6 datasets and IL-34 is down-regulated significantly in 3 of 4 datasets. White rows and grey rows denote statistically significant and non-significant differences in expression, respectively.
