A–D, Comparison of UTX (A and C) and MLL4 (B and D) mRNA levels between normal breast tissues and breast carcinoma. Oncomine (A and B) and The Cancer Genome Atlas (TCGA) (C and D) database were used. E and F, Survival analysis of breast cancer patients on the basis of UTX (E) and MLL4 (F) mRNA levels. The publicly available dataset from TCGA (774 human breast tumors) was analyzed. High UTX and high MLL4 denotes patients with mRNA levels that are greater than or equal to average plus one standard deviation (UTX-low, n = 683; UTX-high, n = 91; MLL4-low, n = 649; MLL4-high, n = 125). G, Correlation analysis between UTX and MLL4 mRNA levels in the TCGA dataset.
