LINC00632 and breast cancer: Compared with BC cells (MCF‐7, SKBR‐3, MDA‐MB‐231 and HCC‐1937), the corresponding 5‐Fu‐resistant BC cells (MCF‐7/5‐Fu, SKBR‐3/5‐Fu, MDA‐MB‐231/5‐Fu and HCC‐1937/5‐Fu) had elevated CDR1as expression (all P < 0.05) (Figure 1A), indicating that CDR1as may have certain effect on the chemosensitivity of BC cells to 5‐Fu.
