When we analysed the overexpression of a MACC1-GFP fusion protein in addition in the unrelated CRC cell line HT29, we could validate the increase of S100P expression in HT29/MACC1-GFP cells, compared to HT29/GFP control cells (P < 0.05; Fig. 1c). The gene discussed is MACC1; the disease is colorectal carcinoma.
