Transcripts of other SLC family members involved in cell metabolism, eg. SLC2A2 (GLUT2), SLC2A3 (GLUT3), and SLC16A1 (monocarboxylic acid transporter 1; MCT), are also overexpressed in ESCC patients (Supplementary Table 5). This evidence concerns the gene SLC2A2 and esophageal squamous cell carcinoma.
