Fig. 2: Expression of PRRX1 in human MPNST tissues.

a Criteria for choosing human MPNST tissue samples. b Immunostaining of PRRX1 in human MPNST tissues. Sections derived from human MPNST were stained with PRRX1 and representative images of PRRX1-low or PRRX1-high tumours are shown. c, d Comparison of overall survival or distant metastasis between PRRX1-low and PRRX1-high MPNST patients. The Kaplan–Meyer survival curve demonstrates significant differences (log-rank test, p < 0.05). e Correlation of PRRX1 levels with patient clinical and pathological characteristics.
