The mRNA expression levels of SLC1A3 in tumour tissues from the clinical samples (n = 3) were evaluated using qPCR and found to be significantly higher than those in non‐cancerous tissues (Figure 1C, P < 0.05), a result was further confirmed by Western blotting (Figure 1D, P < 0.001). This evidence concerns the gene SLC1A3 and neoplasm.
