Hillman et al found that miR‐200b/c and miR‐217 can bind to mortalin mRNA and decrease its expression in K562 cells.52 Our experiments have shown that overexpression of mortalin can partly reverse the proliferation and migration ability of ovarian cancer cells induced by NF‐κB p65 downregulation. The gene discussed is HSPA9; the disease is ovarian cancer.
