From: Gene Expression Profiling of the Hedgehog Signaling Pathway in Human Meningiomas
mRNA levels of PTCH1, SMO, GLI2 and FOXM1. The figure shows standardized mRNA levels of each gene in six individual normal meninges (N), 23 grade I meningiomas (MGI), 9 grade II meningiomas (MGII) and 4 grade III meningiomas (MGIII). Median values are indicated for normal meninges and each tumor group by horizontal bars. P values for the three tumor grades versus normal tissue are as in Table 2.
