Fig. 1. The expression of HOXB9 and its clinical significance in endometrial cancer.
a The staining scores of HOXB9 expression level were dichotomized into two groups, low (score of 0 or 1) and high (score of 2 or 3). We have displayed the representative images of “low” and “high” staining, as well as negative controls, in endometrial carcinoma, normal proliferative endometrium and atypical hyperplasia tissues. b The high expression ratio of HOXB9 in normal proliferative endometrium, atypical endometrial hyperplasia and endometrial carcinoma were showed. c The HOXB9 expression correlation in endometrial carcinoma with histological grade and lymph node metastasis status. d The Kaplan–Meier analysis of HOXB9 expression in endometrial carcinoma was performed. e, f The expression level of HOXB9 in human endometrial cancer compared with normal tissues in TCGA database e, and the Kaplan–Meier analysis of HOXB9 expression in human endometrial cancer in TCGA f. The statistical analyses were performed by one-way ANOVA analyses b, c, Student’s t-test e and Kaplan–Meier analysis d, f. *P < 0.05
