ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expression feature of heterogeneous nuclear ribonucleoprotein K in gastric carcinoma and its clinical significance, and to explore the relationship between hnRNPK expression and Helicobacter pylori L-form infection.</p><p><b>METHODS</b>The expression of hnRNPK protein was examined in 100 cases of gastric carcinoma, 50 paracancerous gastric tissues and 30 matched normal gastric mucosa by Elivision immunohistochemistry and hnRNPK-mRNA by in situ hybridization. Hp-L was detected with Gram staining and immunohistochemical staining.</p><p><b>RESULTS</b>The positive rates of hnRNPK protein and mRNA in gastric carcinoma were 82.0% and 86.0%, respectively, significantly higher than those in the paracancerous gastric tissues and normal controls (P < 0.05). The expression of hnRNPK protein was significantly correlated with histological differentiation, TNM stage and lymph node metastasis (P < 0.05). The positive rates of Hp-L in the three groups were 67.0%, 58.0% and 23.3%, respectively. The positive rate of Hp-L in gastric carcinoma had no significant correlation with it in the paracancerous gastric tissues, but was significantly higher than it in the normal controls (P < 0.05). In gastric carcinoma, the expression of hnRNPK protein was higher in cases of Hp-L positive patients than those of Hp-L negative cases (P < 0.05). Positive correlation existed between the expression of hnRNPK protein and Hp-L infection (r = 0.391, P < 0.01).</p><p><b>CONCLUSIONS</b>There is a higher expression of hnRNPK in gastric carcinoma. Hp-L infection may be associated with the up-regulated hnRNPK expression. The two factors may play a synergetic role in gastric carcinogenesis.</p>
