NMUR2 and cancer: Regarding NMUR2, although our preliminary gene quantification data suggests that its transcript level is elevated in the high graded tumors (Supplementary Figure S3), neither the NMUR2 expression data analyzed from the TCGA endometrial carcinoma cohort nor the NMUR2 protein staining summarized from an endometrial tissue microarray showed a significant difference between normal and cancer tissues (Supplementary Figure S6).
