In order to further confirm the authenticity of this conclusion, 40 GAC pairs of cases were used and paired with paracancer tissues obtained clinically in our center to study the differences in RNA (n = 40, Figure 1e) and protein (n = 2, Figure 1f) expression of SMPDL3B, and SMPDL3B was also shown to be substantially expressed in gastric cancer tissues, according to the findings. The gene discussed is SMPDL3B; the disease is gastric cancer.
