For examples, circRNA AGFG1 acts as a sponge of miR-195-5p to promote triple-negative breast cancer progression through regulating CCNE1 expression [10]; miR-760 suppresses human colorectal cancer cell growth by targeting BATF3AP-1/cyclinD1 signaling [11]; MiR-4319 suppresses the malignancy of triple-negative breast cancer by regulating self-renewal of cancer stem cells [12]. This evidence concerns the gene CCNE1 and triple-negative breast carcinoma.
