Figure 1.

Reg IV mRNA and protein expression in 20 glioma tissues in different grades and non-neoplastic brain tissues were respectively detected by real-time quantitative RT-PCR assay and Western blot analysis. (A) Expression levels of Reg IV mRNA in glioma tissues with different grades and non-neoplastic brain tissues. (B) Expression levels of Reg IV protein in glioma tissues with different grades and non-neoplastic brain tissues. (C) A graphical representation of the Reg IV mRNA level expression profiles in (A). (D) A graphical representation of the Reg IV protein level expression profiles in (B). 'N' refers to non-neoplastic brain tissues; 'I ~ II' refers to glioma tissues with grade I ~ II; 'III ~ IV' refers to glioma tissues with grade III ~ IV. *P < 0.01, compared with ‘N’; ‘**’P < 0.001, compared with ‘N’.
