Figure 3From: High nuclear expression levels of histone-modifying enzymes LSD1, HDAC2 and SIRT1 in tumor cells correlate with decreased survival and increased relapse in breast cancer patients Expression of LSD1, HDAC2 and SIRT1 in different tumor stages. We included 182 patients with a stage I disease, 227 patients with a stage II disease and 51 patients with a stage III tumor. (A) Boxplot showing the percentage of positive tumor cells for LSD1 versus the TNM tumor stage (I-III) at moment of diagnosis. (B) HDAC2 expression levels versus TNM tumor stage shown in a boxplot. (C) The expression levels of SIRT1 versus TNM tumor stage represented in a boxplot. The thick horizontal lines represent the mean percentage of positive tumor cells in each category. Outliers are represented by circles. The p-values were calculated using the one-way ANOVA method and p-values ≤0.05 are considered as significant.Back to article page
