Validation of the potential biomarkers in MEC. A RNA level of NEFL in SGTs by RT-PCR. * P < 0.05, ** P < 0.01, one-way ANOVA. B Expression of NEFL was detected on TMA sections in a cohort with 367 samples. Immunoreactivity (IR) was scored as negative (IR = 0), weak (IR = 1), moderate (IR = 2), and strong (IR = 3). C The representative images of NEFL in MEC by IHC staining. Scale bar, 100 μm. D RNA level of PTP4A1 in SGTs by RT-PCR. ** P < 0.01, *** P < 0.001, **** P < 0.0001, one-way ANOVA. E Expression of PTP4A1 was detected on TMA sections in a cohort with 388 samples. F The representative images of PTP4A1 in MEC by IHC staining. Scale bar, 100 μm
