ZBTB4 and breast cancer: miR-106a-5p increases cell migration and invasion by inhibiting the anti-metastatic gene TGFBR2 (transforming growth factor-β receptor 2) in colorectal cancer [16], inhibits the cellular extrinsic apoptotic pathway by targeting FAS in gastric cancer [10], and promotes cell growth and invasion by targeting ZBTB4 (zinc-finger and BTB domain containing 4) in breast cancer [14].
