| 2 | Short mucin 6 alleles are associated with H pylori infection显示文摘AIM: To investigate the relationship between mucin 6 (MUC6) VNTR length and H pylori infection. METHODS: Blood samples were collected from patients visiting the Can Tho General Hospital for upper gastrointestinal endoscopy. DNA was isolated from whole blood, the repeated section was cut out using a restriction enzyme (PvuⅡ) and the length of the allelefragments was determined by Southern blotting. H pylori infection was diagnosed by 14C urea breath test. For analysis, MUC6 allele fragment length was dichotomized as being either long (> 13.5 kbp) or short (≤ 13.5 kbp) and patients were classif ied according to genotype [long- long (LL), long-short (LS), short-short (SS)].RESULTS: 160 patients were studied (mean age 43 years, 36% were males, 58% H pylori positive). MUC6 PvuⅡ-restricted allele fragment lengths ranged from7 to 19 kbp. Of the patients with the LL, LS, SS MUC6 genotype, 43% (24/56), 57% (25/58) and 76% (11/46) were infected with H pylori, respectively (P = 0.003).CONCLUSION: Short MUC6 alleles are associated with H pylori infection. | Thai V Nguyen Marcel JR Janssen Paulien Gritters René HM te Morsche Joost PH Drenth Henri van Asten Robert JF Laheij Jan BMJ Jansen | 2006 | World Journal of Gastroenterology2006，12，37： | 1 |
