Abstract:
Objective To detect expression of SNCG and CXCR4 mRNA in gastric adenocarcinoma and evaluate its function in carcinogenesis, progression, infiltration, and metastasis, as well as the correlation of these proteins.
Methods The expression of SNCG and CXCR4 mRNAs was detected using reverse transcription-polymerase chain reaction in gastric adenocarcinoma and normal gastric mucosa.
Results The expression of SNCG and CXCR4 mRNAs was obviously higher in gastric adenocarcinoma than in normal gastric mucosa (P < 0.01). The expression of SNCG mRNA was closely correlated with tumor infiltration depth (P < 0.05) and lymph node metastasis (P < 0.01). The expression of CXCR4 mRNA closely correlated with lymph node metastasis (P < 0.01). The expression of SNCG and CXCR4 mRNAs positively correlated in 29 cases of gastric adenocarcinoma (r=0.346, P < 0.05).
Conclusion SNCG and CXCR4 may be overexpressed in tumor tissue and may have important functions in tumorigenesis, progression, infiltration, and metastasis of gastric adenocarcinoma.
