SLC2A belongs to the solute carrier 2 family with 14 isomers (SLC2A1–14) have been currently identified, which are involved in transmembrane transport of carbohydrates.34 SLC2A expression was significantly upregulated in tumour cells and promoted glucose metabolism.35 According to the location of extracellular long loops in the structure of SLC2A proteins, SLC2A can be divided into three types. Here, SLC2A1 is linked to neoplasm.
