Abstract:
Objective To explore the expression levels of YBX1 and FOXA1 in gastric cancer tissues and determine their relationship with prognosis. Methods A total of 131 patients with gastric cancer were studied, and the corresponding adjacent normal tissues of each patient were selected as the control. qRT-PCR and immunohistochemistry were used to detect the expression levels of YBX1 and FOXA1 in cancer tissues and adjacent tissues. The correlation between YBX1 and FOXA1 protein expression in gastric cancer tissues was expressed by Crammer's V coefficient, and the correlation between YBX1 mRNA and FOXA1 mRNA was analyzed by Pearson method. Kaplan-Meier method was used to analyze the relationship between YBX1, FOXA1 protein expression in gastric cancer tissues and the 5-year overall survival rate of patients. Univariate and multivariate Cox regression analyses were used to analyze the factors affecting the prognosis of patients with gastric cancer. Results Compared with paracancerous tissue, the levels of FOXA1 and YBX1 in cancer tissues were lower and higher, respectively (P < 0.05). A negative correlation was observed between YBX1 mRNA and FOXA1 mRNA in gastric cancer (r=-0.675, P < 0.05). The expression of YBX1 and FOXA1 proteins in gastric cancer tissues was negatively correlated (Crammer's V=-0.497, P < 0.001). The expression of YBX1 and FOXA1 proteins in gastric cancer tissue was related to the degree of differentiation, lymph node metastasis, and TNM staging (P < 0.05). The 5-year survival rate of the YBX1 negative expression group and the FOXA1 positive expression group were higher than those of the YBX1 positive expression group, and the FOXA1 negative expression group both P < 0.05). TNM staging and YBX1 were independent risk factors for death in patients with gastric cancer (P < 0.05), and FOXA1 was a protective factor (P < 0.05). Conclusion YBX1 is highly expressed and FOXA1 is lowly expressed in gastric cancer tissues; they are closely related to the disease progression and prognosis of patients with gastric cancer.
