主 题:Cripto-1 Phosphorylation STAT3 Gastric cancer Precancerous lesions Immunohistochemistry
摘 要:AIM:To explore the relationship between Cripto-1 (CR-1) and tyrosine phosphorylation STAT3 (p-STAT3) expressions in gastric cancer (GC) and gastric carcinogensis and ***: The PV9000 immunohistochemical method was used to detect the expression of CR-1 and p-STAT3 in 178 cases of GC, 95 matched normal gastric mucosa, 40 chronic atrophic gastritis (CAG), 48 intestinal meta-plasia (IM) and 25 dysplasia (DYS). RESULTS: The positive rates of CR-1 and p-STAT3 expression were significantly higher in CAG (65.0% and 60.0%), in IM (83.3% and 77.1%), DYS (80.0% and 68%) and GC (71.3% and 60.1%) than in normal gastric mucosa (43.2% and 41.1%, P 0.05), respectively. The expressions of CR-1 and p-STAT3 (78.3% and 66.7%) were signifi cantly higher in GC with lymphnode metastasis than in those without metastasis (53.1% and 42.9%, P 0.05). CR-1 expression was also related to histological and Lauren s types of GC (P 0.001). Furthermore, there was positive relation-ship between CR-1 and p-STAT3 expressions in GC (rk = 0.189, P = 0.002).CONCLUSION: The up-regulation of CR-1 and p-STAT3 may play important roles in gastric carcinogenesis and lymph node metastasis. CR-1 and p-STAT3 expression in GC was positively correlated, and the relevant molecular mechanism requires further investigations.
