The results showed that the mRNA levels of FN1 were generally higher in gastric cancer tissues and cells, when compared with the levels in matched normal tissues and cells, respectively (Figure 6A,B).We also found that 80% of tumor-derived tissues showed higher FN1 protein levels, whereas most normal gastric tissues exhibited low FN1 protein levels, as compared with the levels in the paired tumor tissues (Figure 6C). Here, FN1 is linked to gastric cancer.
