The protein level analysis of the tissues (adjacent tissue, primary tumour tissue, and metastatic tumour tissue from the same GC patients) showed that the p50 protein level slightly fluctuated, while the hTERT protein level gradually increased, and the PLEKHA7 protein level gradually decreased from adjacent tissue to metastatic tissue (Fig. 7C). The gene discussed is NFKB1; the disease is gastric cancer.
