E2F1 and endometrial endometrioid adenocarcinoma: For example, an L-FFL motif constituted by E2F1, miR-15b, and IQCH-AS1, and an M-FFL motif made of E2F1, miR-15b and BCL2 formed a complex L-M-FFL motif in uterine corpus endometrioid carcinoma, but only the L-FFL motif correlated with patient survival (P=0.002, Figure 5D).
