Abstract
Underlying diseases might be risk factors for poor prognosis in patients with coronavirus disease (COVID-19); however, we still do not know whether these diseases are independent factors affecting prognosis, which type of underlying diseases are risk factors, and which type of clinical outcomes are affected. We retrospectively reviewed cohort data from 7,590 de-identified patients with COVID-19 who were diagnosed using severe acute respiratory syndrome-coronavirus-2 RNA polymerase chain reaction test up to May 15, 2020. We used linked-medical claims data provided by the Health Insurance Review and Assessment Service in South Korea. Underlying diseases were identified using the diagnostic codes in the patients’ files from January 1, 2019 to December 31, 2019. The total mortality rate was 3.0% in patients with COVID-19. After adjusting for age, sex, and concomitant chronic conditions, we found that congestive heart failure, chronic pulmonary diseases, diabetes without chronic complications, renal diseases, and malignancy were factors that significantly increased the cost of treatment. Cerebrovascular disease, chronic pulmonary disease, and paralysis were found to be independent factors significant in prolonging hospital stay. Diabetes with chronic complications was independently associated with intensive care unit admission. In addition, underlying congestive heart failure (odds ratio [OR], 1.724; P = 0.003), dementia (OR, 1.598; P = 0.012), diabetes with and without chronic complications (OR, 1.821; P = 0.002 and OR, 1.518; P = 0.022, respectively), renal disease (OR, 2.299; P = 0.002), and malignancy (OR, 1.529; P = 0.039) were significant factors associated with death, even after adjustments. Underlying diseases were significant independent factors of the poor prognosis in patients with COVID-19. The effects were variable according to the type of underlying disease and clinical outcome. Therefore, patients with COVID-19 with underlying diseases should be monitored more closely because they are more at risk of a poor prognosis.

Abstract
PURPOSE Despite significant advances have been achieved in cancer therapy, response to conventional treatments like surgery, radiotherapy and chemotherapy varies among individuals. Immunotherapy is known to be an effective strategy for patients who are resistant to the currently available interventions. METHODS Ninety-six male Balb/c mice (aged 6-8 weeks) were selected and divided into twelve groups of eight. Approximately, 1×10(6)of WEHI-164 cells were injected to each mouse for tumor genesis. Five immunotherapy treatments were considered in this study, including Heat Shock Proteins (HSP), Bacillus Calmette-Guérin (BCG), Bifidobacterium, Immuno-Modulator Drug (IMOD) and Thalidomide. After tumor formation, the groups were treated with one or more of these therapies. Tumor size and survival rate was regularly monitored. RESULTS Depending on the treatment group, tumor sizes were different. In some groups, combined treatments demonstrated more inhibitory effects on tumor growth rate. The mice in group (IMOD+ Thalidomide) had the lowest survival rate but group (BCG+ HSP+ Thalidomide) survived until the end of the experiment. CONCLUSION The (HSP+ BCG+ Thalidomide) group exhibited satisfactory outcomes and two third of the mice in this group went into complete remission. Some combination therapies in test groups had significant impacts on survival and tumor growth rate.

Abstract
Despite the widening interest in the possible association between bacteria and different stages of cancer development, our knowledge in its relation to oral cancers remains inadequate. The aim of this review article is to derive a better understanding on the role of various micro-organisms in the etiogenesis of oral cancers through all the available data on the pubmed. Different bacteria have been proposed to induce carcinogenesis either through induction of chronic inflammation or by interference, either directly or indirectly, with eukaryotic cell cycle and signaling pathways, or by metabolism of potentially carcinogenic substances like acetaldehyde causing mutagenesis. Studies have shown diversity of isolated bacterial taxa between the oral cancer tissue specimens and the control, with Exiguobacterium oxidotolerans, Prevotella melaninogenica, Staphylococcus aureus and Veillonella parvula being specific for tumorogenic tissues. Most isolates are saccharolytic and acid tolerant. Streptococcus anginosus, commonly linked with esophageal and pharyngeal cancers, is not of significance in oral cancers. Similarly, significant salivary specificity is noted for three bacteria, namely, Capnocytophaga gingivalis, P. melaninogenica, and Streptococcus mitis in oral cancer patients, making these species salivary markers for the early detection of oral cancers and thus improving the survival rate significantly. Also, such high degree of bacterial specificity in oral cancers has also provoked the designing of new treatment options for cancer prevention by way of vaccine delivery. However, for the success of these steps, a deeper exploration into this subject with a greater understanding is warranted.

Abstract
The incidence of malignancy in transplant recipients is known to be higher than the same in the general population. However, the types of malignancies vary geographically, and the relative risks (RR) for malignancy in transplant recipients, compared with that of the general population, also differ country-by-country. In this study, we investigated the incidence and characteristics of malignancies after renal transplantation in a single center. A total of 2630 renal recipients who underwent surgery between April 1979 and June 2007 were enrolled in this study. The cumulative and interval incidences of malignancies were calculated for every 3 years post-transplantation. One-hundred ninety cases of postrenal transplant malignancies among 177 recipients (6.73%) were reported until 2007. The post-transplant malignancies were detected from 6 to 290 months after transplantation, with a mean duration of 112.6 +/- 66.0 months. Skin cancer [35 (18.4%)] was the most common post-transplant malignancy, followed by thyroid [25 (13.2%)], stomach [22 (11.6%)], colorectal [22 (11.6%)], and urologic cancers [19 (10.0%)]. As the post-transplant period increased, the interval incidence of malignancy correspondingly increased. Virus-related malignancies, such as Kaposi's sarcoma and cervical cancer, developed earlier within the post-transplant period, while urologic cancer, colorectal cancer developed late in the post-transplant period. The recipient's age at the time of transplantation was the sole independent risk factor for post-transplant malignancy based on the multivariate analysis (RR = 2.723, P < 0.0001 in the >50-year-old age group). We should establish strategies for post-transplant malignancy-screening based on the recipient's age at the time of transplantation, the post-transplant interval, and the national trend of post-transplant malignancy.

Abstract
Several infectious diseases are considered to play a causal role in cancer aetiology. It is estimated that in 2003 in the Netherlands at maximum 2553 new cancer cases (3.5% of all new cancer cases) were attributable to infection. This is considerably lower than globally (17.8%) and in developed countries in general (7.7%), as previously estimated by Parkin. Most likely the explanation is that the prevalence of infections in the Netherlands is lower. Infectious agents that cause the highest number of cancer cases in the Netherlands, as well as globally, are Helicobacter pylori (stomach cancer) and the human papilloma virus (mainly cervical cancer).

Abstract
Recent research implicates viral infection as a factor that may contribute to the risk of prostate cancer. Allelic variation at the RNASEL locus is associated with the risk of infection by a newly discovered retrovirus called XMRV, and with hereditary risk of prostate cancer. This evidence suggests that the RNASEL locus has undergone antagonistic coevolution with the retrovirus over evolutionary time. If this is the case, then both the RNASEL locus and the retrovirus should show evidence of positive selection. Here we use molecular-evolutionary methods to investigate the prediction that the RNASEL locus will exhibit evidence of positive selection. We find evidence that positive selection has acted on this locus over evolutionary time. We further find, using a Bayesian estimation procedure, that Asp541Glu, which was found to be associated with prostate cancer risk in Caucasians in a recent meta-analysis, shows an elevated probability of positive selection. Previous studies provide evidence for rapid evolution of the infection-mediating gag gene in the XMRV retrovirus. Taken together, these results suggest that antagonistic coevolution may have occurred between a specific host locus involved in immune defense (RNASEL) and a viral pathogen. In turn, genetic variation associated with this apparent coevolution may influence susceptibility to prostate cancer.

Abstract
Hepatosplenic gammadelta T-cell lymphoma (HSTL) is a clinicopathological entity associated with an immunocompromised status in approximately 25% of patients. Herein is described a case of HSTL in a 53-year-old Brazilian man with seven previous malaria infections, initially misdiagnosed as a hyperreactive splenomegaly due to chronic malaria. A characteristic lymphoid infiltrate was observed in spleen, liver and bone marrow sinusoids/sinuses. Neoplastic cells had a CD45RO+, CD2+, CD7+, CD3+, CD5-, CD8+, CD56+, perforin+, FasL-negative, T-cell receptor (TCR)alphabeta-negative, TCRgammadelta+ profile. Analyses of gamma and delta TCR rearrangements confirmed diagnosis of gammadelta T-cell lymphoma by detecting VgammaI/Vdelta1-Jdelta1 clonal rearrangements. Sensitive polymerase chain reaction (PCR) for Plasmodium falciparum, Epstein-Barr virus and herpesvirus-8 failed to demonstrate infection. The disease progressed to a fatal outcome following cutaneous infiltration and leukemic proliferation. The authors also comment on the association of lymphoma and infection, focusing on PCR diagnosis of TCRgamma and delta clonal rearrangements and the presumed pathogenic events leading to HSTL in the context of chronic malaria infection. Initial lymphomagenic stages might not be direct consequences of antigenic stimulation of Vdelta1 T-cells, but might depend on interactions between gammadelta T and B cells during cooperative or regulatory responses to Plasmodium sp.

Abstract
Research has found that certain bacteria are associated with human cancers. Their role, however, is still unclear. Convincing evidence links some species to carcinogenesis while others appear promising in the diagnosis, prevention or treatment of cancers. The complex relationship between bacteria and humans is demonstrated by Helicobacter pylori and Salmonella typhi infections. Research has shown that H. pylori can cause gastric cancer or MALT lymphoma in some individuals. In contrast, exposure to H. pylori appears to reduce the risk of esophageal cancer in others. Salmonella typhi infection has been associated with the development of gallbladder cancer; however S. typhi is a promising carrier of therapeutic agents for melanoma, colon and bladder cancers. Thus bacterial species and their roles in particular cancers appear to differ among different individuals. Many species, however, share an important characteristic: highly site-specific colonization. This critical factor may lead to the development of non-invasive diagnostic tests, innovative treatments and cancer vaccines.

Abstract
Recent data has shown that viruses such as vesicular stomatitis virus (VSV), a relatively non-pathogenic, negative-stranded RNA virus, can preferentially replicate in malignant cells and less so in normal cells. VSV appears able to carry out this function in transformed cells since these hosts exhibit the hallmarks of flawed host defense, probably involving the interferon system, which is essential for preventing virus replication. The simple genetic constitution of VSV, lack of any known transforming, integrating or reassortment properties, extensive knowledge relating to its interaction with the immune system and the ability to genetically manipulate this agent affords an ideal opportunity to exploit the oncolytic and gene targeting potential of this innocuous virus. Thus, aside from preferentially targeting malignant cells VSV recombinants could be generated that could increase a tumor's susceptibility to chemotherapeutic agents and/ or importantly, the host immune response. Collectively, our data and others demonstrate that VSV as well as other RNA viruses could provide a promising and exciting approach to cancer therapy.

Abstract
The Fanconi anemia (FA) group C protein, FANCC, interacts with STAT1 following stimulation with IFN-gamma and is required for proper docking of STAT1 at the IFN-gamma receptor alpha-chain (IFN-gammaRalpha, IFN-gammaR1). Consequently, loss of a functional FANCC results in decreased activation of STAT1 following IFN-gamma stimulation. Because type I IFN receptors influence the function of type II receptors, and vice versa, we conducted experiments designed to determine whether type I IFN-induced activation of other STAT proteins is compromised in FA-C cells and found that activation of STAT 1, 3, and 5 is diminished in type I IFN-stimulated cells bearing Fancc-inactivating mutations. We also determined that the reduced activation of STATs was accompanied by significant reduction of type I IFN-induced tyrosine kinase 2 and Jak1 phosphorylation. Because tyrosine kinase 2 plays a role in differentiation of Th cells, we quantified cytokine secretion from CD4+ cells and in vitro generated CD4+ Th cell subsets from splenocytes of Fancc null mice to that of heterozygous mice and discovered reduced CD4+ IFN-gamma secretion in the Fancc-/- mouse, indicating impaired Th1 differentiation. We suggest that Fancc mutations result in a subtle immunological defect owing to the failure of FANCC to normally support Jak/STAT signaling.

Abstract
While for most cancers incidence and mortality are decreasing, those of non-Hodgkin's lymphoma (NHL) are steadily increasing. Research to define reasons for this increase is extensive, but has not yet resolved them. We have conducted a literature analysis on trends regarding changes in the incidence, geographic distribution, and etiologic factors of NHL. From our own and previous analyses, an increasing NHL incidence at a rate of 3-4% per year was observed for the 1970s and 1980s. This stabilized in the 1990s, nevertheless still with an annual rise of 1-2%, resulting in almost a doubling of the NHL incidence. This rise has been noted worldwide, particularly in elderly persons >55 years. Concerning gender subgroups, a male predominance throughout all age groups is apparent. Although the NHL incidence has historically been higher in whites than blacks, disproportional increases have recently been observed in the latter group. Increases in high-grade NHL and extranodal disease are predominant. Differences in geographic distribution are striking for follicular lymphoma, which is more common in Western countries than elsewhere. Asians have higher rates of aggressive NHL, T-cell lymphomas, and extranodal disease. In the Middle East, high rates of intestinal extranodal disease are observed, whereas in Africa, endemic Burkitt's lymphoma accounts for a substantial proportion. Risks for developing NHL include immunosuppression and a causal link between infectious agents, and lymphomagenesis has also been determined, particularly for human T-cell leukemia/lymphoma virus type 1 (HTLV-1), Epstein-Barr virus (EBV), and Helicobacter pylori infections. Exposure to environmental agents and occupational risks have been studied; however, their significance is as yet uncertain.

Abstract
A population-based, incidence case-control study was conducted among women in upstate New York to determine whether pesticide exposure is associated with an increase in risk of non-Hodgkin lymphoma (NHL) among women. The study involved 376 cases of NHL identified through the State Cancer Registry and 463 controls selected from the Medicare beneficiary files and state driver's license records. Information about history of farm work, history of other jobs associated with pesticide exposure, use of common household pesticide products, and potential confounding variables was obtained by telephone interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using an unconditional logistic regression model. The risk of NHL was doubled (OR = 2.12; 95% CI, 1.21-3.71) among women who worked for at least 10 years at a farm where pesticides were reportedly used. When both farming and other types of jobs associated with pesticide exposure were combined, there was a progressive increase in risk of NHL with increasing duration of such work (p = 0.005). Overall cumulative frequency of use of household pesticide products was positively associated with risk of NHL (p = 0.004), which was most pronounced when they were applied by subjects themselves. When exposure was analyzed by type of products used, a significant association was observed for mothballs. The associations with both occupational and household pesticides were particularly elevated if exposure started in 1950-1969 and for high-grade NHL. Although the results of this case-control study suggest that exposure to pesticide products may be associated with an increased risk of NHL among women, methodologic limitations related to selection and recall bias suggest caution in inferring causation.

Abstract
Iatrogenic Kaposi's sarcoma develops in patients undergoing immunosuppressive treatment and is considered to be induced by activation of latent HHV8. In most cases the first manifestation of Kaposi's sarcoma develops after 1 year from when the drug was first administered. In a recent study from Italy on HHV8 positivity in patients with Kaposi's sarcoma, it was found that 52% of the control group were positive (Masini C., et al. G Ital Dermatol Venereol 1999; 134: 315-320). For this reason we could expect a larger number of cases of iatrogenic Kaposi's sarcoma given the number of patients who undergo immunosuppressive treatment for one reason or another. Thus, we have to look to a contemporaneous presence of other factors that co-operate with the HHV8. We present a case of a 49-year-old woman, HHV8 and HCV positive, who develops a Kaposi's sarcoma after 9 months of steroid therapy (methylprednisolone 16 mg/die). The low dose of steroids prescribed to our patient and the fact that the first skin manifestation developed after a shorter period than average from the start of therapy do not explain the acute onset of an extensive Kaposi's sarcoma even taking into account the HHV8 positive status. Both HHV8 and HCV produce proteins, such as IL6 and IL8 which are able to control cell growth. It can be supposed that the contemporaneus presence of the two viruses created a sinergy for the onset of the Kaposi's sarcoma.

Abstract
BACKGROUND Tobacco smoking is the most important but not the only risk factor in lung carcinoma. There is evidence that certain infections, which cause chronic inflammatory reactions, can also induce tumour development. It has recently been shown that patients with chronic pulmonary diseases present a high rate of subclinical Pneumocystis infection, and that the latter is able to induce inflammatory responses and alveolar cell alterations. The possible role of Pneumocystis infection in the development of lung neoplasms thus deserves consideration. MATERIAL AND METHODS Polymerase chain reaction has been used to analyze the presence of DNA of two independent loci of the Pneumocystis genome: the mitochondrial region (mtLSU rRNA) and the gene encoding for the dihydropteroate synthase enzyme, in paraffin-embedded tissue blocks of 10 cases of small cell lung carcinoma (SCLC) and 10 cases of nonsmall cell lung carcinoma (NSCLC) with similar demographic and clinical characteristics. Five cases without lung pathology, and two cases of Pneumocystis pneumonia were also analyzed as controls. RESULTS DNA of the microorganism was found in all the cases of SCLC but in only two of the NSCLC, and in none of the controls without pulmonary disease - thus implying a statistically significant association (P < 0.0001) between subclinical Pneumocystis infection and SCLC. CONCLUSIONS While the nature of this association is not clear, it nevertheless constitutes an important finding - either the infection is specifically facilitated by this tumour or induces the development of this type of neoplasm in combination with other factors.

Abstract
A population-based, incidence case-control study was conducted among women in upstate New York to determine whether histories of certain infections and antibiotic use are associated with risk of non-Hodgkin's lymphoma (NHL). Our study involved 376 cases of NHL identified through the New York State Cancer Registry and 463 controls selected from the Medicare beneficiary files and state driver's license records. Information about use of common medications including antibiotics, history of selected infectious diseases and potential confounding variables was obtained by telephone interview. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using an unconditional logistic regression model. There was a progressive increase in risk of NHL with increasing frequency and duration of systemic antibiotic use, as assessed over the period of 2-20 years before the interview. The ORs for the highest exposure categories, >/=36 episodes and >/=366 days of use, were 2.56 (95% CI 1.33-4.94) and 2.66 (95% CI 1.35-5.27), respectively. These associations were primarily due to antibiotic use against respiratory infections and dental conditions. Moreover, the association with frequency of antibiotic use for respiratory infections was pronounced for marginal zone B-cell lymphoma and for respiratory tract lymphoma. Analyses by class of antibiotics did not suggest that a general cytotoxic effect of antibiotics was responsible for these increased risks. Although recall bias and selection bias remain potential concerns in our study, the results are generally consistent with the hypothesis that persistent infection/inflammation predisposes individuals to the development of NHL. However, a direct role of antibiotics in NHL induction has not been ruled out.

Abstract
Because oncogenic DNA viruses establish persistent infections in humans, continuous immunosurveillance for neoplastic cells is required to prevent virus-induced tumors. Antigen-specific CD8+ T lymphocytes are critical in vivo effectors for eliminating virus-infected and virus-transformed cells. Investigation into the induction, regulation, and maintenance of CD8+ T cells specific for these viruses is hindered by the lack of tractable animal models that mimic natural infection. Resistance to tumors induced by polyoma virus, a persistent natural mouse DNA virus, is mediated by polyoma-specific CD8+ T cells. Mice susceptible to polyoma virus tumorigenesis mount a smaller, albeit still considerable, expansion of anti-polyoma CD8+ T cells; importantly, these antiviral CD8+ T cells lack cytotoxic activity while retaining the phenotype of cytotoxic T lymphocyte (CTL) effectors. In this review, we will discuss potential in vivo mechanisms that regulate the functional competence of anti-polyoma CD8+ T cells, particularly in the context of chronic antigenic stimulation provided by persistent viral infections and tumors.

Abstract
BACKGROUND Hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC) expresses hepatitis B surface antigen (HBsAg) on its cell surface, and this may serve as a tumor-associated antigen. It was shown previously that adoptive transfer of immunity against HBsAg facilitates the suppression of experimental human HCC-expressing HBsAg in athymic mice. The authors recently showed that it was possible to augment the anti-HBV immune response through induction of oral immune regulation for HBV-associated antigens. The objective of this study was to evaluate the effect of oral immune regulation for HBV antigens on the growth of HBsAg-expressing HCC. METHODS Recipient athymic Balb/c mice were irradiated sublethally and injected with 10(7) human hepatoma cells followed by the adoptive transfer of 2 x 10(6) splenocytes from donor mice. Four groups of donor Balb/c mice were studied: Two groups were immune modulated through oral administration of HBV antigens (HBsAg, PreS1, and Pre S2) or bovine serum albumin (BSA). Two control groups were immunized for HBsAg and fed HBV antigens or BSA. Recipient mice were followed for tumor volume and serum alpha-fetoprotein (aFP) levels. The humoral immune response was determined by measuring serum HBs antibodies. HBV specific T-cell immune modulation was assessed in vitro by HBV specific T-cell proliferation and interferon gamma (IFNgamma) ELISPOT assays as well as cytokine expression by reverse transcriptase-polymerse chain reaction assays. RESULTS The adoptive transfer of orally immune modulated HBV splenocytes induced complete tumor suppression in recipient mice compared with control mice transplanted with nonimmune modulated cells (BSA), which showed significant tumor growth (serum aFP levels were 3.5 ng/mL and 2320.0 ng/mL, respectively). Control mice transplanted with anti-HBs immunized cells (with or without oral immune modulation) manifested similar tumor suppression (3.5 ng/mL and 0.5 ng/mL, respectively). Immunoregulation for HBV antigens augmented the HBV specific T-cell immune response, as manifested by an increase in HBV specific T-cell proliferation and IFNgamma ELISPOT assays in mice orally immune regulated with HBV proteins compared with naïve mice. Tumor suppression was mediated through increased IFNgamma production in immune regulated and immunized mice. CONCLUSIONS The induction of oral immune regulation for HBV antigens modulated the antitumor immune response, thus suppressing the growth of HCC in mice. This effect was mediated by the enhancement of anti-HBV specific T-cell immunity.

Abstract
At the present time, the etiology of epithelial ovarian cancer is poorly understood. It has recently been recognized that certain chronic infectious agents may contribute to carcinogenesis by inducing a state of persistent inflammation. Since the female upper genital tract is a frequent site of chronic infections, we propose various strategies that may be useful for determining the potential role of chronic infection and persistent inflammation in the pathogenesis of epithelial ovarian cancer.

Abstract
The mechanism by which hepatocellular carcinoma (HCC) develops and the role of the hepatitis B virus (HBV) in inducing tumors, are not yet well understood. Patients persistently infected with HBV tend to have a defective immune response against the virus, which fails to clear the virus and also induces liver injury. This defective response may also have an inducible effect on the virus and on cells that express HBV antigens, as well as play a role in the growth of neoplasm. It is possible that one of the mechanisms of tumor growth is related to a deviant immune response towards viral or tumor associated antigens. We describe two responses against the tumor. A 'good' response that would suppress the tumor and a 'bad' response that would promote it and theorize that the net balance between 'bad' and 'good' responses of the immune system towards a cancerous cell and/or antigen will predict whether a tumor grows or is suppressed. Oral tolerance involves the induction of immunological hyporesponsiveness towards specific antigens. It was shown that oral tolerance induces antigen-specific immune suppression towards tumor-associated-antigens by feeding of HBV or other tumor proteins. We hypothesize that induction of immune tolerance towards tumor-associated antigens will suppress the immune response towards these antigens, thus reducing the 'bad' response. The proposed new treatment strategy would redirect the focus from augmenting anti-tumor immune responses to inducing host tolerance towards the tumor.

Abstract
Nuclear factor-kappaB (NF-kappaB) is a transcriptional regulator of inducible expression of genes including cyclooxygenase-2 (COX-2), regulating cell proliferation. NF-kappaB is kept silent in the cytoplasm via interaction with the inhibitory protein IkappaBalpha and transmigrated into the nucleus upon activation. However, constitutive NF-kappaB has been found in the nucleus of some cancer cells. We investigated the role of NF-kappaB in COX-2 expression and cell proliferation in human gastric cancer AGS cells. AGS cells were treated with antisense oligodeoxynucleotide (AS ODN) or sense oligodeoxynucleotide (S ODN) for the NF-kappaB subunit p50, or they were transfected with a mutated IkappaBalpha gene (MAD-3 mutant) or a control vector, pcDNA-3. AGS cells were treated with COX-2 inhibitors such as indomethacine and NS-398 or prostaglandin E2. mRNA expression for COX-2, and protein levels for p50, IkappaBalpha, and COX-2 were determined by reverse transcription polymerase chain reaction and Western blot analysis. The NF-kappaB levels were examined by electrophoretic mobility shift assay. Thromboxane B2 (TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) levels were determined by enzyme-linked immunosorbent assay. Cell proliferation was assessed by viable cell counting, [3H] thymidine incorporation, and colony formation. The nuclear level of p50 decreased in AGS cells treated with AS ODN. The IkappaBa mutant was observed in cells transfected with the mutated IkappaBa gene. NF-kappaB was inhibited in cells treated with AS ODN or transfected with the mutated IkappaBalpha gene, compared with the cells treated with S ODN or transfected with control vector. Cell proliferation, mRNA expression and protein level of COX-2, and production of TXB2 and 6-keto-PGF1alpha were inhibited in cells treated with AS ODN or transfected with the mutated IkappaBalpha gene, which had lower NF-kappaB levels than cells treated with S ODN or transfected with control vector. COX-2 inhibitors suppressed cell proliferation and production of TXB2 and 6-keto-PGF1alpha, in a dose-dependant manner. Prostaglandin E2 prevented the inhibition of proliferation in cells treated with AS ODN or transfected with the mutated IkappaBalpha gene. In conclusion, NF-kappaB mediates COX-2 expression, which may be related to cell proliferation, in human gastric cancer cells.
