“…Several studies have shown that human breast cancer tissues and cells lines (MDA-MB-468, MCF-7, and Hs578T) reveal the marked overexpression of CBS, CSE, and 3MST compared to normal breast cells [ 31 , 132 , 180 ]. Recently, our research group has highlighted the potential regulation of CBS and CSE in breast cancer cell lines by miR-4317 [ 31 ] and miR-939-5p [ 181 , 182 ]. It is worth mentioning that, recently, miR-548 and miR-193 have been found by our research group to simultaneously target the three synthesizing enzymes in breast cancer: CBS, CSE and 3MST ( Table 2 ) [ 132 , 183 ].…”
