Abstract
AIM: To detect the expression of Wnt3, Wnt3a, Wnt5a, Wnt8a and β-catenin in chronic atrophic gastritis (CAG) and gastric carcinoma (GC), and to investigate the role of the Wnt signaling pathway in the pathogenesis of GC.
METHODS: The mRNA expression of Wnt3, Wnt3a, Wnt5a and Wnt8a in 26 fresh CAG and 40 GC tissue samples was examined using Real-time RT-PCR. The protein expression of β-catenin was detected by Western blot.
RESULTS: The mRNA expression levels of Wnt3 and Wnt3a were significantly increased in GC (1.9940 ± 0.1311 vs 1.3349 ± 0.2487, P < 0.05; 2.3033 ± 0.3979 vs 1.2835 ± 0.2815, P < 0.05) and were associated with lymph node metastasis and TNM stage. The expression of Wnt5a and Wnt8a did not significantly differ between CAG and GC (both P > 0.05). Western blot analysis showed that the relative expression of β-catenin protein was significantly elevated in GC compared with CAG (0.6290 ± 0.1369 vs 0.2341 ± 0.0975, P < 0.05).
CONCLUSION: Our results suggest that Wnt3 and Wnt3a may be critically involved in the activation of the Wnt signaling pathway and in the carcinogenesis and progression of GC.
