Abstract
PURPOSE Gastritis caused by infection with Helicobacter pylori is characterized by chronic inflammation and damage in gastric tissue, which is a main risk factor for gastric cancer. Associated with H. pylori, the TP53 gene tumor suppressor and the cell adhesion glycoprotein epithelial cadherin develop a relevant role in the integrity and carcinogenesis of the epithelium. We aimed to detection of H. pylori and its main virulence markers and measured the messenger RNA (mRNA) expression levels of E-cadherin and TP53 genes. METHODS The detection of H. pylori and its virulence markers, as well as the mRNA expression levels of E-cadherin and TP53 genes, were obtained for 161 samples of gastric biopsies including 37 with normal gastric tissue, 70 with gastritis, 24 from neoplastic tissue, and 27 from adjacent non-neoplastic by means of a quantitative real-time polymerase chain reaction. RESULTS The mRNA expression levels of E-cadherin and TP53 were found to be decreased in patients with gastritis, independently of H. pylori infection. In samples from gastric patients, the neoplastic tissue showed an accentuated decrease of expression; on the other hand, the expression of E-cadherin was normal in adjacent non-neoplastic. CONCLUSIONS No evidence was found of the involvement of the cagA and vacA genes in the decreased expression of E-cadherin and TP53. The process of carcinogenesis is complex, and the decrease of the E-cadherin gene expression and TP53 gene expression appears to contribute significantly.

Abstract
AIM: To explore whether recombinant human lactoferrin (rhLF) plus triple therapy can increase the rate of Helicobacter pylori(H. pylori) eradication, reduce gastric mucosal inflammation, and inhibit vacuolating cytotoxin (VacA) mRNA expression.
METHODS: One hundred and ninety-two H. pylori ATCC43504 infected Babl/c mice with gastritis were randomly divided into four groups: A (rhLF+standard triple therapy), B (rhLF alone), C (standard triple therapy alone), and D (saline). H. pyloricolonization of the gastric mucosa was assessed by silver staining. Gastric mucosal inflammation was assessed by HE staining. Tumor necrosis factor (TNF)-α content was determined by ELISA. VacA mRNA expression was detected by RT-PCR.
RESULTS: Compared with group D, the rate of H. pylori colonization and gastric mucosal inflammation score decreased significantly in groups A, B, and C (P < 0.05). Compared with groups B and C, the rate of H. pylori colonization and gastric mucosal inflammation score decreased significantly in group A (P < 0.05). rhLF plus standard triple therapy significantly decreased gastric TNF-α content (28.64 pg/mL ± 12.07 pg/mL vs 300.16 pg/mL ± 59.1 pg/mL, 54.96 pg/mL ± 15.02 pg/mL, 503.25 pg/mL ± 1.35 pg/mL, P < 0.01) and VacA mRNA expression (P < 0.01) compared with groups B, C and D.
CONCLUSION: rhLF combined with triple therapy can improve H. pylori eradication rate, reduce gastric mucosal inflammation possibly by inhibiting proinflammatory factor release, and effectively inhibit VacA mRNA expression.

Abstract
OBJECTIVES The APC gene mutation triggers familial adenomatous polyposis (FAP) and approximately 80% of sporadic colorectal cancers. FAP summarizes the natural history of colorectal cancer because low- and high-grade dysplastic lesions and adenocarcinoma are simultaneously present in the same patients free from individual and environmental variability factors. Estrogen receptor beta (ERβ) has recently been suggested as the most likely mediator of estrogen-related anti-carcinogenic effects in Apc(Min-/+) mice and humans. In this study we assessed the ERβ expression in the intestinal mucosa of FAP patients to verify its possible involvement in tumor progression in colorectal cancer. MATERIAL AND METHODS ERβ and ERα expression, cell proliferation (Ki-67) and apoptosis (TUNEL), were evaluated on archival biopsy material from six patients with FAP who underwent colectomy. RESULTS A progressive significant decrease of ERβ expression was observed in the different stages of the disease as compared to normal mucosa (p < 0.001). Interestingly, a decreased ERβ expression was directly correlated with apoptosis (r = 0.76, p < 0.001), and inversely correlated with cell proliferation (r = 0.54, p < 0.05). CONCLUSIONS ERβ expression is related to the severity of the disease, supporting the role of ERβ as a relevant biomarker of tumor progression and possible chemopreventive target in patients at risk of colonic neoplasia.

Abstract
Hepatocarcinogenesis is a process attributed to progressive genomic changes that alter the hepatocellular phenotype producing cellular intermediates that evolve into hepatocellular carcinoma (HCC). During the preneoplastic phase, the liver is often the site of chronic hepatitis and/or cirrhosis, and these conditions induce liver regeneration with accelerated hepatocyte cycling in an organ that is otherwise proliferatively at rest. Hepatocyte regeneration is accelerated by upregulation of mitogenic pathways involving molecular and genetic mechanisms. Hepatic growth factors, inhibitors and triggers may also play a role. This process leads to the production of monoclonal populations of aberrant and dysplastic hepatocytes that have telomerase re-expression, microsatellite instability, and occasionally structural aberrations in genes and chromosomes. Development of dysplastic hepatocytes in foci and nodules and the emergence of HCC are associated with the accumulation of irreversible structural alterations in genes and chromosomes even if the genomic basis of the malignant phenotype is largely heterogeneous. Therefore, a malignant hepatocyte phenotype may be produced by changes in genes acting through different regulatory pathways, thus producing several molecular variants of HCC. On these bases, a key point for future research will be to determine whether the deletions are specific, due to particular loci in the minimally deleted regions of affected chromosome arms, or whether they are non-specific with loss of large portions of chromosomes or entire chromosome arms leading to passive deletion of loci. The final aim is the possibility of identifying a step where carcinogenetic processes could be terminated.

Abstract
BACKGROUND The current guidelines suggest the use of triple therapy as first choice treatment of Helicobacter pylori infection, although the eradication failure rate is more than 30%. Current interest in probiotics as therapeutic agents against H. pylori is stimulated not only by the clinical data showing efficacy of some probiotics in different gastrointestinal diseases but also by the increasing resistance of pathogenic bacteria to antibiotics, thus the interest for alternative therapies is a real actual topic. AIM To review in vitro and in vivo studies on the role of probiotics in H. pylori infection focusing on the paediatric literature. MATERIALS AND METHODS Pre-clinical and clinical paediatric studies in English assessing the role of probiotics in H. pylori infection identified by MEDLINE search (1950-2009) were reviewed. RESULTS In vitro studies demonstrated an inhibitory activity of probiotics on H. pylori growth and that this effect is extremely strain specific. Available data in children indicate that probiotics seems to be efficacious for the prevention of antibiotic associated side-effects, and might be of help for the prevention of H. pylori complications by decreasing H. pylori density and gastritis, and for the prevention of H. pylori colonization or re-infection by inhibiting adhesion to gastric epithelial cells. There is no clear evidence that probiotics may increase the H. pylori eradication rate. CONCLUSION Both in vitro and in vivo studies provide evidence that probiotics may represent a novel approach to the management of H. pylori infection.

Abstract
BACKGROUND A pivotal role of oestrogen receptor-beta has been suggested in colon carcinogenesis in humans. However, few data are available on oestrogen receptor-beta in colorectal pre-cancerous lesions. AIM In the present study, we evaluated oestrogen receptor-beta expression and its possible correlation with proliferative activity and apoptosis in colorectal adenomas and normal colon tissue. PATIENTS/METHODS Adenomatous tissue from 25 patients with colonic polyps, and normal tissue from 25 controls were used. Oestrogen receptor-beta expression, colonocyte proliferation (expressed as PCNA positivity) and apoptosis were evaluated. RESULTS In adenomatous tissue, a significant reduction of oestrogen receptor-beta was observed compared to normal mucosa (10.1+/-5.5% vs. 44.2+/-13.7; p<0.03), while the expression of oestrogen receptor-alpha remained unvaried. Cell proliferative activity significantly increased in adenomatous tissue compared to normal mucosa (59.3+/-7.1 vs. 18.5+/-8.8; p<0.0001), doubling the PCNA/apoptosis ratio. An inverse correlation was found between oestrogen receptor-beta and PCNA expression in adenomas (r=-0.81), a datum confirmed by confocal microscopy evaluation. CONCLUSIONS Our data demonstrate, for the first time, a significant reduction of oestrogen receptor-beta expression already in the pre-cancerous phase of colon carcinogenesis. This suggests a role of selective oestrogen receptor-beta agonists in the prevention of colorectal cancer.

Abstract
It is well established that host-bacterium interactions play a critical role in the initiation and progression of periodontal diseases. By the use of inhibitors, it has been shown that mediators associated with the innate immune response significantly contribute to the disease process. Less is known regarding the role of the acquired immune response. To investigate mechanisms by which the acquired immune response to Porphyromonas gingivalis could affect connective tissue, we used a well-documented calvarial model to study host-bacterium interactions. Injection of P. gingivalis stimulated gamma interferon, interleukin 6, macrophage inflammatory protein 2, and monocyte chemoattractant protein 1 expression as determined by real-time PCR. Prior immunization against P. gingivalis significantly enhanced the mRNA levels of these cytokines and chemokines. Similarly, immunization significantly increased and prolonged the formation of a polymorphonuclear leukocyte and mononuclear cell infiltrate (P < 0.05). In addition, the area of connective tissue destruction, osteoclastogenesis, bone loss, mRNA expression of proapoptotic genes, and degree of fibroblast apoptosis were increased in immunized mice (P < 0.05). These results indicate that activation of the acquired immunity by P. gingivalis increases the inflammatory and destructive responses which occur in part through up-regulating the innate immune response and enhancing osteoclastogenesis and fibroblast apoptosis.

Abstract
A 62-year-old Japanese woman with RA received an eradication therapy against Helicobacter pylori in November 1999. Eight weeks later, successful eradication was confirmed by negative results for rapid urease test, pathologic findings, and a fall in anti-H. pylori IgG antibody titer. During the course, parameters for RA activity were exacerbated: C-reactive protein 1.1-4.2 mg/dL, rheumatoid arthritis precipitation antigen 2560-5120 dils., erythrocyte sedimentation rate 52-123 mm/h, and complements CH50 50 to over 60 U/mL. Lansbury index increased from 70% to 105%. Two more weeks later, the patient noticed right shoulder pain. She also complained of bilateral gonalgia two months later, and physical examination revealed increased fluid in the knee joints. Prednisolone was required to control the disease activity. The results of this case suggested that RA patients might experience a deleterious effect on the disease activity following H. pylori eradication possibly through disruption of the established oral tolerance against stress protein such as mycobacterial heat shock protein 65.

Abstract
BACKGROUND Functional probiotics may prevent Helicobacter pylori infection, and some evidence suggests that they also possess antitumor properties. Lactobacillus brevis (CD2) is a functional Lactobacillus strain with peculiar biochemical features, essentially related to the activity of arginine deiminase. This enzyme catalyzes the catabolism of arginine and affects the biosynthesis of polyamines (putrescine, spermidine, and spermine). Polyamines are polycations found in high concentrations in both normal and neoplastic cells. Our aims were: 1, to assess whether oral administration of L. brevis (CD2) affects H. pylori survival in the human gastric mucosa; 2, to evaluate the effects of L. brevis (CD2) on polyamine biosynthesis in gastric biopsies from H. pylori-positive patients. MATERIALS AND METHODS For 3 weeks before endoscopy, 22 H. pylori-positive dyspeptic patients randomly received (ratio 1 : 1) high oral doses of L. brevis (CD2) or placebo. Before and after treatment, H. pylori infection was determined by urea breath test (UBT). In gastric biopsies, ornithine decarboxylase activity and polyamine levels were, respectively, evaluated by a radiometric technique and high-pressure liquid chromatography (HPLC). RESULTS L. brevis (CD2) treatment did not eradicate H. pylori. However, a reduction in the UBT delta values occurred, suggesting a decrease in intragastric bacterial load. Significantly, L. brevis (CD2) induced a decrease in gastric ornithine decarboxylase activity and polyamine levels. CONCLUSIONS Our data support the hypothesis that L. brevis (CD2) treatment decreases H. pylori colonization, thus reducing polyamine biosynthesis. Alternatively, the arginine deiminase activity following L. brevis (CD2) administration might cause arginine deficiency, preventing polyamine generation from gastric cells.
