Steamed Ginger Extract Exerts Anti-inflammatory Effects in Helicobacter pylori-infected Gastric Epithelial Cells through Inhibition of NF-κB. J Cancer Prev 2021; 26:289-297. [PMID: 35047455 PMCID: PMC8749313 DOI: 10.15430/jcp.2021.26.4.289] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 12/22/2021] [Accepted: 12/23/2021] [Indexed: 12/13/2022] Open
Abstract
Ginger (Zingiber officinale) has traditionally been used as a treatment for inflammatory diseases in the Asian region. Recently, anti-inflammatory effects of steamed ginger extract (GGE03) have been reported, but its association with Helicobacter pylori (H. pylori)-induced gastritis has not been investigated. The purpose of this study was to assess the anti-inflammatory activity of GGE03 in H. pylori-infected gastric epithelial cells. Our studies revealed that the GGE03 suppressed the growth of H. pylori. GGE03 markedly reduced the expression of the H. pylori-induced pro-inflammatory cytokines including interleukin (IL)-8, TNF-α, IL-6, inducible NOS (iNOS) and IFN-γ. We also demonstrated that GGE03 treatment inhibited the H. pylori-activated NF-κB signaling pathway. In addition, the treatment with GGE03 significantly attenuated nitric oxide production and myeloperoxidase activity in H. pylori-infected gastric epithelial cells. These anti-inflammatory effects of GGE03 were more effective than ginger extract. Finally, we investigated the minimum effective concentration of GGE03 to inhibit H. pylori-induced inflammation. Our findings suggest that GGE03 not only inhibits the growth of H. pylori, but also attenuates H. pylori-induced inflammation.

[PMID: 33409257 PMCID: PMC7783239 DOI: 10.15430/jcp.2020.25.4.244] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2020] [Revised: 12/10/2020] [Accepted: 12/12/2020] [Indexed: 12/16/2022] Open
Abstract
Helicobacter pylori is recognized as a risk factor for gastric carcinogenesis. The chronic exposure of gastric epithelium to H. pylori induces a prolonged inflammatory state that may progress to gastric cancer. Astaxanthin, a pinkish antioxidant carotenoid, abundant in marine organisms, is known for its protective effect against inflammation and multiple types of cancer. The purpose of this study was to examine the effect of astaxanthin on H. pylori-induced oxidative injury, inflammation, and oncogene expression in gastric mucosal tissues of the infected mice. Mice were inoculated using oral gavage with H. pylori suspension (108 colony forming unit of H. pylori/0.1 mL) for three days, after which they were fed astaxanthin-supplemented diet (5 mg/kg body weight/day for seven weeks). The effects of astaxanthin on H. pylori-induced increase in lipid peroxide (LPO) production, myeloperoxidase (MPO) activity, expression of the inflammatory cytokine IFN-γ and oncogenes (c-myc and cyclin D1), and the accompanying histologic changes in gastric mucosal tissues were evaluated. H. pylori infection increased the level of LPO, MPO activity, and the expression of IFN-γ, c-myc, and cyclin D1 in gastric mucosal tissues of mice. H. pylori infection induced neutrophil infiltration and hyperplasia of gastric mucosa. Astaxanthin supplementation attenuated these effects. In conclusion, consumption of astaxanthin-rich foods may prevent H. pylori-associated oxidative damage and inflammatory and oncogenic responses in gastric mucosal tissues.

Abstract
BACKGROUND/AIMS Toll-like receptors (TLRs), particularly TLR2 and TLR4, take part in elicitation of immune responses against Helicobacter pylori (H. pylori). This study aimed to investigate the relationship between single nucleotide polymorphisms (SNP) rs3804099 in the TLR2 gene and rs4986790 in the TLR4 gene with H. pylori infection and peptic ulcer (PU). MATERIALS AND METHODS Blood specimens were obtained from 350 individuals, including 100 H. pylori-infected patients with PU, 125 H. pylori-infected asymptomatic subjects (AS), and 125 non-infected healthy subjects (NHS). The DNA was extracted, and the SNPs were determined using ARMS-PCR method. RESULTS The frequency of CT genotype at TLR2 SNP rs3804099 in both the PU and AS groups was significantly higher than in the NHS group (p<0.05). In total H. pylori-infected individuals (PU+AS), the frequency of the CT genotype at rs3804099 was also significantly higher than in the NHS group (p<0.005). The frequency of the CC genotype at rs3804099 in PU+AS was markedly lower than in the NHS group (p=0.066). PU patients carried CT genotype more frequently than total healthy individuals (AS+NHS) (p<0.03). The distribution of the TT genotype was lower, whereas the frequency of the CT genotype was higher in AS individuals infected with CagA+ strains than those infected with CagA- strains (p<0.03). No significant differences were found among the PU, AS, and NHS groups regarding the genetic differences at rs4986790 in the TLR4 gene. CONCLUSION These results provide evidence regarding the association of the rs3804099 in the TLR2 gene with H. pylori infection and PU. The rs3804099 may affect vulnerability to H. pylori infection, particularly to CagA+ strains of bacteria.

Abstract
Background The pro- and anti-inflammatory cytokines play an important role in the immune response against H. pylori infection. The proinflammatory cytokines of Th17 cells have been suggested to play a major role in H. pylori infection and resulting gastric inflammation. Objective The objective of this study was to compare the expression of selected inflammatory cytokines (IL-10, IL-17, IL-21, IL-23, and TNF-α) in H. pylori-infected patients and healthy controls and to understand their association with H. pylori infection and disease severity. Results The expression levels of IL-17 and IL-23 were significantly higher in H. pylori-infected patients. The expression of IL-21 was also higher in H. pylori-positive patients but there was no significant association with infection. IL-17 expression showed a significant increase with the severity of chronic gastritis. Conclusion The proinflammatory cytokine, IL-17, shows a significant association with H. pylori infection and disease severity in a Sri Lankan dyspeptic patient population.

Abstract
PURPOSE Tumor necrosis factor alpha (TNF-α), a multifunctional cytokine, is involved in apoptosis, cell proliferation, cell survival, and inflammation. It plays a dual role in cancer development and progression. It has been revealed that polyunsaturated fatty acids (PUFAs) modulate the production and activity of TNF family cytokines. The objective of the present study was to evaluate the effect of PUFAs on messenger RNA expression levels of TNF-α in patients with gastric adenocarcinoma. METHODS Thirty-four chemotherapy-naive patients diagnosed with gastric adenocarcinoma were randomly divided into two groups. The first group (17 individuals) received cisplatin without supplements and the second group (17 individuals) received cisplatin plus orally administered PUFA supplements for 3 weeks, based on treatment strategies. The gastric biopsy samples were obtained from all participants before and after treatment, and TNF-α mRNA expression levels were evaluated by quantitative real-time PCR procedure. RESULTS Our findings revealed that TNF-α mRNA expression is downregulated in group II, after receiving cisplatin and omega fatty acid supplement for 3 weeks. However, this difference is not statistically significant (p > 0.05). TNF-α mRNA expression did not show significant alteration in group I, after receiving cisplatin alone. CONCLUSIONS Taken together, we concluded that omega fatty acids reduce TNF-α expression at the mRNA level in patients with gastric adenocarcinoma. These data suggest that TNF-α may act as a potential target for the therapy of human gastric adenocarcinoma.

Abstract
Gastroduodenitis caused by H. pylori, often acquired in early childhood, is found in about 50% of the adult population. Although H. pylori infections can remain asymptomatic, its virulence factors usually trigger epithelial vacuolization and degeneration, loss of microvilli, disintegration of cytoplasm, and leukocyte accumulation. It is believed that leukocyte infiltration is driven by cytokines produced locally in infected tissue. However, so far little is known about changes in serum cytokines in juvenile patients infected with H. pylori. Serum cytokine profiles were analyzed in 62 juvenile patients diagnosed with gastroduodenitis using the Bio-Plex multiplex assay. H. pylori infection was confirmed in 32 patients, while 30 patients were H. pylori-free. Cytokines CXCL5 and CXCL6, potent neutrophil chemoattractants, were upregulated in all patients diagnosed with gastroduodenitis. Serum levels of IL8, a prototype neutrophil attractant, remained unchanged in subjects with gastroduodenitis relative to controls. Therefore, our data suggest that CXCL5 and CXCL6 play a role in directing neutrophil trafficking into inflamed gastroduodenal tissue. In addition, the CCL25/GM-CSF ratio differed significantly between H. pylori-positive and -negative juveniles. Further, study is needed to evaluate the role of CCL25 and GM-CSF in the pathogenesis of the different etiologies of gastroduodenitis.

Abstract
There have been few studies concerning the cytokine profiles in gastric mucosa of Helicobacter pylori-infected patients with normal mucosa, chronic gastritis, and gastric carcinoma (GAC).In the present study, we aimed to elucidate the genomic expression levels and immune pathological roles of cytokines-interferon (IFN)-γ, tumor necrosis factor (TNF)-α, interleukin (IL)-4, IL-6, IL-10, transforming growth factor (TGF)-β, IL-17A, IL-32-in H pylori-infected patients with normal gastric mucosa (NGM; control), chronic active gastritis (CAG), and GAC. Genomic expression levels of these cytokines were assayed by real-time PCR analysis in gastric biopsy specimens obtained from 93 patients.We found that the genomic expression levels of IFN-γ, TNF-α, IL-6, IL-10, IL-17A mRNA were increased in the CAG group and those of TNF-α, IL-6, IL-10, IL-17A, TGF-β mRNA were increased in the GAC group with reference to H pylori-infected NGM group.This study is on the interest of cytokine profiles in gastric mucosa among individuals with normal, gastritis, or GAC. Our findings suggest that the immune response of gastric mucosa to infection of H pylori differs from patient to patient. For individual therapy, levels of genomic expression of IL-6 or other cytokines may be tracked in patients.

Abstract
Different amounts of ingested alcohol can have distinct effects on the human body. However, there is limited research on chronic alcohol consumption with Helicobacter pylori infection. We sought to investigate the relationship between the cytokine profile, oxidative balance and H. pylori infection in subjects with chronic alcohol consumption. A total of 142 subjects were divided into three groups: 59 subjects with chronic alcohol ingestion and H. pylori infection (group A); 53 subjects with chronic alcohol ingestion without H. pylori infection (group B); and 30 control subjects (group C). The serum levels of CagA, interleukin (IL)-10, E-selectin, TNF-α, malondialdehyde (MDA) and superoxide dismutase (SOD) activity were measured by enzyme-linked immunosorbent assay (ELISA). We found that the ages and serum H. pylori CagA levels among the three groups, as well as both the mean drinking age and the mean daily alcohol consumption between groups A and B, were matched and comparable. Comparing the BMIs among the three groups, the BMI differences were found to be statistically significant (F=3.921, P<0.05). Compared with group C, the BMIs in groups A and B were significantly higher (P<0.001 and P<0.01, respectively); however, the BMI differences between group A and group B were not statistically significant (P>0.05). Additionally, no differences in the serum CagA levels were found in comparisons among the groups (all P>0.05). The serum IL-10 and E-selectin levels in group A were significantly lower than those in group B (serum IL-10: P<0.05; E-selectin: P<0.05). The serum IL-10 in group A was significantly higher than that in group C (P<0.01); the serum E-selectin levels in group A did not significantly differ compared with those in group C (P>0.05). Furthermore, the serum IL-10 and E-selectin levels in group B were significantly higher than those in group C (serum IL-10: P<0.001; E-selectin: P<0.05); however, the serum TNF-α levels did not differ among groups (all P>0.05). Although the serum levels of MDA and SOD in groups A and B were slightly lower than those in group C, there were no significant differences among groups (all P>0.05). In conclusion, we believe that H. pylori infection might cause a significant inhibition of certain cytokine profiles in subjects with chronic alcohol ingestion. Moreover, chronically ingested alcohol may exert an adjusted inflammatory effect, but there was no association between H. pylori infection, chronic alcohol consumption and oxidative balance.

Abstract
The aim of the present study was to determine the preventive effect of insect tea against reserpine-induced gastric ulcers in ICR mice. A high (800 mg/kg) dose of insect tea reduced the serum levels of the proinflammatory cytokines interleukin (IL)-6, IL-12, tumor necrosis factor (TNF)-α and interferon (IFN)-γ compared with those in mice treated with a low (400 mg/kg) dose and the control mice. The serum levels of somatostatin (SS) and vasoactive intestinal peptide (VIP) in mice treated with insect tea were higher compared with those in the control mice; however, the serum levels of motilin (MOT) and substance P (SP) were lower in mice treated with insect tea than in the control mice. Gastric ulcer inhibitory rate of the insect tea treatment group of mice were much lower compared to the control mice, and the high concentration treated mice were similar to the ranitidine treated mice. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in mice treated with insect tea were higher compared with those in control mice, and similar to those in normal mice and ranitidine-treated mice. The nitric oxide (NO) and maleic dialdehyde (MDA) levels of mice treated with a high concentration of insect tea compared with the normal group were close. Using quantitative polymerase chain reaction (qPCR) assays, the present study revealed that insect tea significantly induced inflammation in the tissues of mice by downregulating the expression of nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2, and upregulating the expression of nuclear factor of κ light polypeptide gene enhancer in B-cells inhibitor α (IκB-α). These results suggest that insect tea is as effective at preventing gastric ulcers as the gastric ulcer drug, ranitidine and it can be used as medicine.

Abstract
This project's aim was to determine the reserpine-induced gastric ulcer preventive effect of polysaccharide of Larimichthys crocea swim bladder (PLCSB) in ICR mice. The anti-gastric ulcer effects of polysaccharide of Larimichthys crocea swim bladder was evaluated in mice model using morphological test, serum levels assay, cytokine levels assay, tissue contents analysis, reverse transcription-polymerase chain reaction (RT-PCR) analysis and western bolt assay. High concentration (50 mg/kg dose) of PLCSB reduced IFN-γ as compared to low concentration (25 mg/kg dose) and control mice. SS and VIP serum levels of PLCSB treated mice were higher than those of control mice, and MOT and SP serum levels were lower than control mice. Gastric ulcer inhibitory index of PLCSB treatment groups mice were much lower than control mice, and the high concentration treated mice were similar to the ranitidine treated mice. The SOD and GSH-Px activities of PLCSB treated mice were higher than control mice, close to normal mice and ranitidine treated mice. PLCSB treated mice also showed the similar contents of NO and MDA to normal group. By RT-PCR and western blot assay, PLCSB significantly induced inflammation in tissues of mice by downregulating NF-κB, iNOS, and COX-2, and upregulating IκB-α. These results suggest that PLCSB showed a good gastric ulcer preventive effect as the gastric ulcer drug of ranitidine. Polysaccharide of Larimichthys crocea swim bladder may be used as a drug material from marine products.

Abstract
Yellow tea is a traditional Chinese drink widely used in Asia. The aim of this study was to determine the antioxidant activity of yellow tea and its preventive effect on gastric injury. The antioxidant effects were determined by measuring the 1,1-diphenyl-2-picryhydrazyl (DPPH) free radical- and hydroxyl radical-scavenging activity. The yellow tea extract demonstrated high antioxidant activity in the assays of DPPH and hydroxyl radical-scavenging activity. Additionally, an animal model was used to investigate the preventive effect of yellow tea on gastric injury. High concentrations of yellow tea reduced the levels of the serum pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-α to a greater extent than low concentrations. The extent of the gastric injury was significantly reduced by yellow tea, which demonstrated its anti-inflammatory properties. Yellow tea demonstrated the strongest inhibitory effect (74.6%) against gastric injury when administered at a dose of 1,000 mg/kg by gavage. These results suggest that yellow tea possesses good antioxidant activity and a preventive effect on gastric injury in vivo.
