Figure 1. LINC00899 is downregulated in human breast cancer tissues and cell lines. (A) Comparison of the relative LINC00899 expression levels between 26 pairs of breast cancer (BC) tissues and adjacent normal tissues. (B) Comparison of the relative LINC00899 expression levels between the normal human mammary epithelial cells (MCF-10A) and 5 BC cell lines. Data presented as means ± SD, *p< 0.05, **p< 0.01.
