RIPK4 and gastric cancer: Table 2 displays the results. The RIPK4 protein expression level was significantly correlated with the N and TNM stages of GC patients (p < 0.05). In contrast, there was no correlation with the age, gender, T stage, and differentiation degree of GC patients (p > 0.05), suggesting that RIPK4 protein expression in GC tissue has a certain predictive effect on the lymph node metastasis and TNM staging of GC patients.
