Expectedly, PTCSC3 led to a markedly decrease in glucose uptake, lactate production and ATP level in both TPC‐1 and BCPAP cell lines (Figure 3A–C), and the lactate levels in tumour tissues from control mice were substantially higher than those in PTCSC3 overexpression group (Figure 3D). This evidence concerns the gene PTCSC3 and neoplasm.
