The expression of LUCAT1 and miR-181a-5p in tissues and cells. RT-qPCR was used to detect expression levels of LUCAT1 in BC tumor tissues and adjacent tissues (a, b), and cells including normal MCF-10A cells and breast cancer cell lines SKBR3, MCF7, MDA-MB-231, MDA-MB-468, MDA-MB-435 (c), demonstrating that LUCAT1 was overexpressed. RT-qPCR was used to detect expression levels of miR-181a-5p in BC tumor tissues and adjacent tissues (d), and cells including normal MCF-10A cells and breast cancer cell lines SKBR3, MCF7, MDA-MB-231, MDA-MB-468, MDA-MB-435, demonstrating that miR-181a-5p was expressed lowly (e). *p < 0.05, n = 31
