CLXN and lung adenocarcinoma: We analyzed the expression of EFCAB1 in lung adenocarcinoma from GEPIA data (http://gepia.cancer‐pku.cn/index.html), and the results showed that the level of EFCAB1 mRNA in LUAD was significantly lower than that of adjacent tissues (Figure 1D), but it was not related to clinical stage (Figure 1E), which is consistent with our results.
