The results suggested that LMAN2 knockdown significantly suppressed tumor growth (Figure 7A) and decreased tumor size (Figure 7B) and tumor weight (Figure 7C) compared with those in the sh‐control group, while the MAPK activator inhibited the sensitivity of MCF‐7/DDP cells to DDP induced by LAMN2 knockdown. The gene discussed is LMAN2; the disease is neoplasm.
