HOXB9 and cancer: Here, the transcription of HOXB9 mRNA was upregulated in EC patients compared with healthy individuals in subgroup analysis based on patient’s age (Fig. 2D), patient’s race (Fig. 2E), patient’s weight (Fig. 2F), menopause status (Fig. 2G), histological subtypes (Fig. 2H), TP53 mutant status (Fig. 2I), and individual cancer stages (Fig. 2J) (P < 0.05).
