Therefore, we analysed the mRNA expression levels of PTTG3P in 63 pairs of GC tissues and adjacent non‐tumours (ANTs) and found that PTTG3P was significantly up‐regulated in 68.3% (43 of 63) of the GC tissues compared with the ANTs (P = 0.021, Fig. 1B). The gene discussed is PTTG3P; the disease is neoplasm.
