SLC27A5 and signet ring cell carcinoma: The results showed that, except in signet ring cell carcinoma (n = 6), the expression of FATP5 in adenocarcinoma (n = 8), mucinous adenocarcinoma (n = 8) and adenosquamous carcinoma (n = 5) was significantly higher than paracancerous tissues, which verified that FATP5 plays an important role in colorectal cancer (Figures 7B–E).
