LTB4R and breast cancer: A comparison of modTNBC samples (moderately methylated modTNBC cluster; red dashed rectangle in Figure 1) and six samples of normal breast tissue (NORM, green dashed rectangle in Figure 1) by CpG pair methylation level at different distances from the LTB4R gene transcription start site using the Mann–Whitney test showed statistically significant abnormal hypomethylation in breast cancer TN tissues (p < 0.05) at position +149 from the LTB4R TSS (Figure 2).
