To examine the biological role of XPO1 in liposarcoma, the gene was first suppressed using shRNA targeting to XPO1 resulted in 70–90% silencing of XPO1 protein in liposarcoma cells (LPS141, SW872, MLS402 and SA4) compared to scramble shRNA as shown by western blot analysis (Figure 1E). Here, XPO1 is linked to liposarcoma.
