The Western blotting analysis resulted in a level of expression of FZD-10 in the EVs from the GC patients of 1.49 ± 0.396 ratio before surgery, 1.765 ± 0.356 ratio 72 h after surgery, 1.484 ± 0.236 ratio 30 days after surgery, before chemotherapy, and finally 0.324 ± 0.034 30 days after the end of the treatment. The gene discussed is FZD10; the disease is gastric cancer.
