dc.description.abstract | H.pylori enhances mesenchymal-EMT markers and CD44-immunostaining in gastric non-cancerous mucosa and eradicating H.pylori reduces this, suggesting H.pylori plays a role in initiating gastric cancer by recruiting CSCs via EMT and anti-H.pylori therapy can prevent gastric cancer in H.pylori-infected individuals.We know little concerning the expression of transforming growth factor-beta 1 (TGF-beta 1) and TGF-beta 1-induced epithelial-mesenchymal transition (EMT) markers in gastric mucosa and their changes after eradication of Helicobacter pylori infection have not yet been clarified. In the present study, we compared the time course of messenger RNA (mRNA) expression of TGF-beta 1 and five EMT markers (Twist, Snail, Slug, vimentin and E-cadherin) in 111 controls, 55 patients with gastric dysplasia and 71 patients with early gastric cancer, following eradication of H.pylori. mRNA levels in non-cancerous gastric mucosa were measured using quantitative real time-polymerase chain reaction and the histologic findings of gastric mucosa were compared before and after eradication. The average duration of follow-up was 46.7 months (6.0-112.4). The levels of TGF-beta 1, Twist, Snail, Slug and vimentin mRNA, in addition to levels of CD44 detected by immunohistochemistry, showed all up-regulation in patients with dysplasia or early gastric cancer compared with controls (P < 0.05); moreover, the mRNA levels of E-cadherin, an epithelial marker, were decreased in these patients compared with the control group (P < 0.001). Eradication of H.pylori reduced the expression of TGF-beta 1, Twist, Snail, Slug and vimentin mRNA (P-value for slope < 0.001), as well as the immunohistochemical expression of CD44 (P = 0.014), whereas it enhanced the expression of E-cadherin (P-value for slope < 0.05). Thus, H.pylori infection may trigger the TGF-beta 1-induced EMT pathway and the emergence of gastric cancer stem cells (CSCs). Its eradication may prevent the carcinogenesis of gastric cancer by inhibiting these two pathways. | - |
