The expression and prognostic significance of SLC2A4RG in glioma. (a) SLC2A4RG mRNA expression detected via RT-PCR in normal brains and human glioma specimens with different WHO grades. (b, d, and e) Total, cytoplasmic, and nuclear immunoreactivity scores of SLC2A4RG in the second independent cohort of normal brains, LGGs, and HGG. (c) Representative staining images of SLC2A4RG in normal brains and gliomas. (f and g) The percentages of cytoplasmic SLC2A4RG (f) and nuclear SLC2A4RG (g) in these specimens calculated based on b, d, e. (h) The protein level of nuclear SLC2A4RG analyzed in the third independent cohort containing normal brains, LGG and HGG specimens by western blot. (i) The fold change of SLC2A4RG protein is normalized to Histone 3A. (j) Kaplan-Meier curves were used to analyze the relationships between the total/cytoplasmic/nuclear SLC2A4RG immunoreactivity level and OS in glioma patients from the second cohort. Student's t-test, ns, no significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001.
