NRBP2 and cancer: The colony formation assays also suggested that less colonies were formed by cancer cells in the setting of NRBP2 overexpression when the same number of cells were plated (oe-NC vs. oe-NRBP2: TPC-1: 213.41 vs. 132.58, p = 0.0007; CAL62 = 185.27 vs. 18.31, p = 0.0013) (Figure 2(d)).
