LUCAT1 and breast cancer: This interaction between LUCAT1 and miR-181a-5p translated to the observation that miR-181a-5p mediated the tumor-promoting effects of ectopic overexpression of LUCAT1, as evidenced by the attenuated in vitro BC cell proliferation and in vivo tumor growth after co-transfection of miR-181a-5p mimic and pc-LUCAT1.
