GIPC1 and colorectal neoplasm: When classifying the tumors in a low and a high MACC1 expressing group, GIPC1 expression was higher in those colorectal tumors that also express MACC1 at high levels (median 69.72 GIPC1 mRNA/% calibrator vs. 46.78 GIPC1 mRNA/% calibrator in the low expressing group, P=0.014; Figure 5D).
