LINC02154 and esophageal squamous cell carcinoma: Moreover, although LINC02154 expression was upregulated in both EAC and ESCC as compared to normal esophageal tissues (Supplementary Fig. 1A), when TCGA-ESCA tumors were divided into EACs and ESCCs, the association between the LINC02154 expression level and T stage was not statistically significant, perhaps due to the small numbers of samples in the respective categories (Supplementary Fig. 1B and C).
