To further demonstrate whether FUT8 overexpression in prostate cancer cells promotes the proliferation of cells in normal or androgen-ablated conditions, we preformed the MTS assay on the LAPC4 cells that were stably selected to overexpress FUT8 (LAPC4-FUT8) or control vectors (LAPC4 Ctr). This evidence concerns the gene FUT8 and Familial prostate cancer.
