The expression of lincRNAs were not significantly different between HER2-negative and HER2-positive breast cancer tissues (for lincRNA-BC2, P = 0.542; for lincRNA-BC4, P = 0.866; for lincRNA-BC5, P = 0.176; lincRNA-BC8, P = 0.166) (Figure 4A). The gene discussed is ERBB2; the disease is breast cancer.
