Moreover, in order to evaluate whether CD71 and Claudin18.2 are highly expressed in different stages of cancer development, we analyzed the expression of CD71 and Claudin18.2 in gastric cancer patients with different stages, and Fig. 1B–C showed that both molecules were highly expressed in different stages of gastric cancer, demonstrating that CD71 and Claudin18.2 as dual targets are suitable for all stages of gastric cancer development. Here, TFRC is linked to cancer.
