Abstract
Background: Acute graft-versus-host disease (aGVHD) is a common and severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Some studies have found that the presence of certain specific human leukocyte antigen (HLA) loci could affect the occurrence of aGVHD. Meanwhile, the impact of HLA haplotypes on aGVHD has been rarely studied. This study aimed to investigate the effects of HLA loci and haplotypes on intestinal aGVHD. Methods: Totally, 345 consecutive patients undergoing first HLA-matched sibling peripheral blood stem cell transplantation (PBSCT) from February 2004 to June 2013 at Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, were enrolled in this study. HLA loci and haplotypes of recipients with frequency over 5% were searched and their effects on intestinal aGVHD were investigated. Other important factors including donor age, recipient age, donor-recipient sex combinations, and conditioning regimens were also evaluated using logistic regression. Pure upper gastrointestinal tract aGVHD without diarrhea was excluded because the histological proof was unavailable. The follow-up end-point was 6 months after HSCT. Results: The cumulative incidence of intestinal aGVHD was 19.4%, with 18.0% of the patients classified as classic aGVHD and 1.4% as persistent, recurrent, or late aGVHD. Multivariate analysis showed that HLA-A31 locus (odds ratio [OR] 2.893, 95% confidence interval [CI] [1.054, 7.935], P = 0.039), HLA B40-DR15 (OR 3.133, 95% CI [1.250, 7.857], P = 0.015), and HLA B46-DR9 haplotypes (OR 2.580, 95% CI [1.070, 6.220], P = 0.035), female donor for male recipient (OR 2.434, 95% CI [1.319, 4.493], P = 0.004) were risk factors for intestinal aGVHD. Conclusion: The presence of certain HLA loci and haplotypes may influence the occurrence of intestinal aGVHD in PBSCT with HLA-identical sibling donors.

Abstract
Objective The HLA haplotype has been associated with many autoimmune diseases, but no
associations have been described in sepsis. This study aims to investigate the HLA
system as a possible marker of genetic sepsis susceptibility. Methods This is a prospective cohort study including patients admitted to an intensive
care unit and healthy controls from a list of renal transplant donors. Patients
with less 18 years of age; pregnant or HIV positive patients; those with
metastatic malignancies or receiving chemotherapy; or with advanced liver disease;
or with end-of-life conditions were excluded. The DNA was extracted from the whole
blood and HLA haplotypes determined using MiliPlex®
technology. Results From October 2010 to October 2012, 1,121 patients were included (1,078 kidney
donors, 20 patients admitted with severe sepsis and 23 with septic shock).
HLA-A*31 positive subjects had increased risk of developing sepsis (OR 2.36, 95%CI
1.26-5.35). Considering a p value <0.01, no other significant association was
identified. Conclusion HLA-A*31 expression is associated to risk of developing sepsis.

Abstract
Tumor-specific cytotoxic T lymphocytes (CTLs) from patients with early-stage tumors are usually more efficient at attacking tumor cells than CTLs from the progressing tumor stages. The authors investigated the antitumor activity of CTLs from gastric cancer patents and healthy donors. In this study, peripheral blood lymphocytes (PBLs) from gastric cancer patients and healthy donors were stimulated with HLA-A matched allogeneic gastric cancer cells such as KATO-3, MKN45, and SGC7901. Three different populations of lymphocyte, p5-CTL-KATO, h4-CTL-MKN45, and h4-CTL-KATO, were induced and expanded. Flow cytometry analyses showed that 85.2% to 97.8% of these cells were CD3-positive and 45.5% to 51.2% were CD8-positive. The induced CTLs efficiently kill HLA-A2 or HLA-A24 gastric cancer cells through CTL-mediated cytotoxicity. However, no effects were observed for other cancer cells or HLA-A2 negative gastric cancer cells. The specific cytotoxicity of the induced CTLs was further confirmed by cold-target inhibition and monoclonal antibody blockage. These results suggest that CTL-mediated cytotoxicity specific for tumor cells can be produced by stimulating PBLs from healthy donors using HLA-A matched tumor cells, which will lead to the development of new immunotherapeutic strategies to kill cancer cells.

Abstract
SUMMARY We previously reported acid-extracted natural antigenic peptide (F4.2 [YSWMDISCWI]) of a gastric signet ring cell carcinoma HST-2 cells, recognized by HLA-A*31012-restricted autologous cytotoxic T lymphocytes, TcHST-2 line. In this study, the full-length cDNA (1101 bp), termed c98, predicting a protein composed of 170 amino acids was obtained. Because TcHST-2 cells could lyse the HLA-A31 antigen (+) allogeneic tumor cells that were introduced with c98 gene, this gene was suggested to possess antigenicity. Beginning at N-terminal 61 amino acid, the N-terminal six amino acid sequence that is completely identical to F4.2 was present in c98; however, a sequence of four amino acids in C-terminal was not found. Nevertheless, this peptide, c98(61-70), seemed to be immunogenic, because cells pulsed with c98(61-70) peptide were lysed in a dose-dependent manner by TcHST-2 cells. The c98 gene was expressed ubiquitously in tumor cells as well as in normal tissues. However, some tumor cells, including HST-2 cells, expressed this antigen in a high content, and such cells were lysed by TcHST-2 cells in the context of HLA-A31 antigen. However, TcHST-2 cells did not lyse cells that expressed lower amounts of c98 than HST-2 cells. These data suggested that c98-gene product and/or c98(61-70) peptides could be used as a candidate for tumor vaccines in cancer immunotherapy.

Abstract
INTRODUCTION Recently, several mice models have been used for investigating cancer metastasis. However, there are no metastatic and peritoneal dominated variants from the same parental cell line. AIM AND METHODOLOGY To elucidate the mechanisms of metastasis, we established highly liver metastatic and peritoneal disseminated models in nude mice, and then characterized several factors related to metastasis in these cells. We established a series of well-characterized sublines that showed metastatic potentials to different organ sites of nude mice. Two sublines were selected sequentially from the parental pancreatic cancer cell line, HPC-4, resulting in a highly liver metastatic cell line, HPC-4H4, and a highly peritoneal disseminated cell line, HPC-4P4a. Using these three cell lines, we investigated several biologic properties and mRNA levels of differentially expressed genes involved in cancer metastasis. RESULTS The tumorigenicity, the motile activity, and the adhesive activity of metastatic sublines were higher than those of parental HPC-4 cells. Macroscopic and microscopic findings and the DNA ploidy pattern were the same among the three cell lines. In addition, HPC-4H4 cells expressed clearly higher levels of vascular endothelial growth factor and IL-8 expression than did HPC-4P4a cells. In fluorescence-activated cell sorter analysis of adhesion molecules, the expression of integrin-alpha2 was enhanced in HPC-4 cells, integrin-alphavbeta5 was enhanced in HPC-4H4 cells, and integrin-alpha3 was enhanced in HPC-4P4a cells. Osteopontin, vascular endothelial growth factor, and hepatocyte growth factor were among the genes that were upregulated in HPC-4H4 cells compared with HPC-4P4a cells. HPC-4P4a cells did not metastasize to the liver by intrasplenic injection. Conversely, HPC-4H4 cells metastasized remarkably to the peritoneum by intraabdominal injection. CONCLUSION These sublines are the first reported liver metastatic and peritoneal disseminated models derived from the same parental cell lines. The results of our study suggest that the process of hematogenous metastasis is not the same as that of peritoneal dissemination.

Abstract
We have identified that HER-2/neu-derived peptides are naturally processed as tumor rejection antigens recognized by tumor-specific, HLA-A2-restricted cytotoxic T lymphocytes in gastric cancer. To evaluate candidates for immunotherapy using HER-2/neu-derived, HLA-A2-restricted peptides, we examined the frequency of HLA-A2 relating to HER-2/neu overexpression or the infiltrating grade of tumor-infiltrating lymphocytes (TILs) in Japanese patients with gastric cancer. HER-2/neu-overexpressing tumors detected by immunohistochemistry amounted to 19% of primary gastric cancers and HLA-A2-positive patients with gastric cancer were 31% of primary gastric-cancer cases. Finally, gastric-cancer patients with both HLA-A2-positive and HER-2/neu-overexpressing tumors amounted to 6.6% of these cases. There was no significant difference in the infiltrating grade of TILs between gastric cancers overexpressing HER-2/neu and those that did not. The candidate for HER-2/neu-based immunotherapy with HLA-A2-restricted peptides represent a very limited population of Japanese patients.

Abstract
We established a new cell line, HPC-3P4a, with high peritoneal disseminated potential in nude mice. HPC-3P4a was derived from a human pancreatic carcinoma cell line (HPC-3) that had low capacity for peritoneal dissemination. HPC-3P4a developed peritoneal dissemination in 10 of 11 (90.9%) cases, whereas parental HPC-3 developed peritoneal dissemination in one of six (16.7%) cases. The metastatic foci in the peritoneum showed essentially the same histologic appearance of parental involvement. The tumorigenicity, motility, and adhesive activity of HPC-3P4a to the extracellular matrix were stronger than were those of the HPC-3. In FACS analysis, HPC-3P4a significantly increased the expression of alpha6 and alpha(v)beta5 integrins, while it decreased alpha2 integrin, hCD44H, and hCD44v 10, as compared with HPC-3. The VEGF production of HPC-3P4a was significantly lower than that of HPC-3. Analysis of gene macroarrays showed a variety of cytokines, interleukin, and other immunomodulatory, and their receptors were up-regulated and down-regulated on an mRNA level in HPC-3P4a cells, compared with HPC-3 cells. Intrasplenic injection of HPC-3P4a produced no liver metastasis. We named our original highly liver metastatic cell line HPC-3H4 (previously reported). This HPC-3H4 cell was established by repeated intrasplenic injection from parental cell HPC-3; thus, it developed high liver metastasis. Moreover, HPC-3H4 developed peritoneal dissemination by intra-abdominal injection. In contrast, HPC-3P4a did not develop liver metastasis by intrasplenic injection. These findings are very interesting and might suggest that the process of hematogenous metastasis differed from that of peritoneal dissemination. Thus, this cell line may be useful for investigating the mechanism of peritoneal dissemination in human pancreatic cancer.

Abstract
We established a new cell line, AZ-P7a, with high peritoneal-metastatic potential in nude mice. AZ-P7a cells were derived from the human gastric carcinoma line AZ-521, which has low capacity for peritoneal dissemination. AZ-P7a cells developed peritoneal metastasis in 11 / 14 (78.6%) mice, whereas the parental AZ-521 cells developed metastasis in 2 / 6 (33.3%) mice. The metastatic foci in the peritoneum showed essentially the same histological appearance as those induced by parental cells. The tumorigenicity and the motile activity of AZ-P7a cells were stronger than those of the parental AZ-521 cells; in contrast, adhesion to the extracellular matrix and the production of vascular endothelial growth factor by AZ-P7a cells were decreased. In fluorescence-activated cell sorter (FACS) analysis, AZ-P7a cells expressed significantly greater levels of integrins alpha2, alpha3, alpha5, alpha6 and alphavbeta5, as compared with AZ-521 cells. However, alpha1, alpha4, alphavbeta3, hCD44H, hCD44v3, hCD44v6 and hCD44v10 were not expressed in either cell line. AZ-P7a cells developed no liver metastasis when administered by the intrasplenic injection method, though the highly liver metastatic cell line AZ-H5c showed the same rate of peritoneal dissemination as that exhibited by AZ-P7a cells after intraabdominal injection. These findings suggested that the mechanism of peritoneal dissemination differed from that of hematogenous metastasis. Moreover, the latter appears to be controlled by more complex mechanisms than the former. Thus, this cell line might be useful for investigating the mechanism of peritoneal dissemination of human gastric cancer.

Abstract
Antigenic peptides have been used as a cancer vaccine in melanoma patients and have led to a drastic regression of metastatic tumors. However, few antigens have been identified in non-melanoma tumors. We recently purified a new natural antigenic peptide, designated F4. 2, by biochemical elution from a human gastric signet cell carcinoma cell line and showed that it is recognized by an autologous human histocompatibility antigen (HLA)-A31-restricted cytotoxic T lymphocyte (CTL) clone. Here we describe in vitro induction of F4. 2-specific CTLs from peripheral blood T lymphocytes of HLA-A31( +) gastric cancer patients. The T cells of seven HLA-A31( +) patients with gastric cancers were stimulated in vitro by F4.2-pulsed autologous dendritic cells which had been induced from peripheral blood of each patient by incubation in the presence of granulocyte macrophage colony-stimulating factor (GM-CSF) and IL-4. We tested the cytotoxicity of the T cells against F4.2-loaded C1R-A*31012 by a 6-h (51)Cr release assay after 3 stimulations with F4.2-pulsed dendritic cells. F4.2-specific cytotoxicity was detectable in the stimulated T cells from two of the seven HLA-A31( +) patients. Further, both F4.2-specific CTLs also lysed the gastric cancer cell line, HST-2, from which F4.2 was derived. These results suggest that F4.2 peptide may be useful as an HLA-A31-restricted peptide vaccine in certain patients with gastric cancer.

Abstract
Abstract
Peptides of human melanomas recognized by CD8+ CTLs have been identified, but the nature of those of nonmelanoma tumors remains to be elucidated. Previously, we established a gastric signet ring cell carcinoma HST-2 and HLA-A31 (A*31012)-restricted autologous CTL clone, TcHST-2. In the present study, we determined the natural antigenic peptides of HST-2 cells. The purified preparation of acid-extracted Ags was submitted to the peptide sequencer, and one peptide, designated F4.2 (Tyr-Ser-Trp-Met-Asp-Ile-Ser-Cys-Trp-Ile), appeared to be immunogenic. To confirm the antigenicity of F4.2 further, we constructed an expression minigene vector (pF4.2ss) coding adenovirus E3, a 19-kDa protein signal sequence plus F4.2. An introduction of pF4.2ss minigene to HST-2 and HLA-A31(+) allogeneic tumor cells clearly enhanced and induced the TcHST-2 reactivity, respectively. Furthermore, when synthetic peptides of F4.2 C-terminal-deleted peptides were pulsed to HST-2 cells, F4.2-9 (nonamers), but not F4.2-8 or F4.2-7 (octamer or heptamer, respectively), enhanced the reactivity of TcHST-2, suggesting that the N-terminal ninth Trp might be a T cell epitope. This was confirmed by lack of antigenicity when using synthetic substituted peptides as well as minigenes coding F4.2 variant peptides with Ala or Arg at the ninth position of F4.2. Meanwhile, it was indicated that the sixth position Ile was critically important for the binding to HLA-A31 molecules. Thus, our data indicate that F4.2 may work as an HLA-A31-restricted natural antigenic peptide recognized by CTLs.

Abstract
To investigate of human pancreatic cancer metastasis to the liver, a pancreatic carcinoma line, HPC-3, was injected into the spleens of nude mice. The cells from a few liver metastatic foci of the mice injected with HPC-3 were expanded in vitro and subsequently injected into the spleens of nude mice. By repeating these procedures, we were able to obtain a cell line, designated HPC-3H4. The mice were observed to have liver metastasis in 6 of 6 (100%) cases injected with HPC-3H4, whereas the rate was 0% at 3 weeks after the intrasplenic injection of HPC-3. The tumorigenicity of HPC-3H4 was more rapid than that of HPC-3. The motile activity of HPC-3H4 was also stronger than that of HPC-3, and the adhesion to the extracellular matrix of HPC-3H4 was stronger than that of HPC-3. We also analyzed the cell surface expression of the metastasis-related adhesion molecules. As a result, no substantial changes were observed in the expression level of adhesion molecules. These results suggest that HPC-3H4 is useful for studies aimed at the prevention of liver metastasis.

Abstract
We have derived HLA-A2.1-restricted, gastric cancer-specific cytotoxic T lymphocyte (CTL) lines by repetitive in vitro stimulation of tumor-associated lymphocytes (TAL) with autologous tumor cells. The HER2/neu specificity of these gastric cancer-specific CTLs was demonstrated using HER2/neu-transfected cell lines and HER2/neu-expressing tumors, and with a set of HER2/neu-derived peptide epitopes. Gastric cancer-specific CTLs specifically lysed autologous and allogeneic HLA-A2.1+, HER2/neu+ gastric cancer cells, HER2/neu-transfected C1R/A2 cell lines (HLA-A2.1+, HER2+) and HLA-A2.1-transfected SW626 tumor cell lines (HLA-A2.1+, HER2+). This recognition could be inhibited by anti-HLA-A2 antibody or by cold target HER2/neu-transfected C1R/A2 cells. Our results demonstrate that the HER2/neu-encoded HLA-A2.1-associated epitopes recognized by CTLs are presented as naturally processed peptides on gastric cancer lines. Furthermore, 3 of 19 tested HER2/neu-derived peptide epitopes [HER2(9(106)), HER2(9(369)), HER2(9(689))], which all bound HLA-A2.1 with high (IC50 < 50 nM) affinity, were able to sensitize HLA-A2+ C1R/A2 cells to be recognized by the gastric cancer-specific CTLs, demonstrating the immunodominance of these epitopes. In conclusion, our findings implicate HER2/neu-derived epitopes as potential candidates for novel immunotherapy and vaccine strategies against gastric cancer.

Abstract
We have attempted to detect telomerase activity by Southern blot analysis using a digoxigenin labeled probe (5'-(CCCTTA)6CCCTAA-3') Telomerase activity was detected in all cancer cell lines that were tested, and:the lower limit for detection was 10(3) cells. Although telomerase activity was detected in colon cancer tissues, it was not found in adenoma or normal tissues. Telomerase activity was completely abrogated by heat and RNase treatment of the CHAPS extract. Our results demonstrate that this nonradioisotopic assay is safe and reliable for detecting telomerase activity in cancer cell lines and biopsy samples.

Abstract
Immune recognition of human cancers except melanoma is not well understood at either the cellular or the molecular level. We demonstrate in this study the existence of HLA class-I-restricted and tumor-specific CTL in IL-2-activated TIL (tumor-infiltrating lymphocytes) of all 4 gastric cancer patients tested. We established HLA A2-restricted and adenocarcinoma-specific CTL in 2 HLA A0201+ patients, and HLA A2402-restricted CTL recognizing both adenocarcinoma and squamous-cell carcinomas (SCC) in the 2 remaining HLA A2402+ patients. Further, HLA A3101-restricted and adenocarcinoma-specific CTL were established in 1 of the 2 HLA A2402+ patients who had HLA A3101 allele. HLA A2-, A2402- and A3101-restricted CD8+ CTL clones were established from these parental CTL lines. The 2 HLA A2-restricted CTL lines lysed 8 of 13 HLA A2+ adenocarcinoma cell lines established from different organs (stomach, colon, lung and breast) with different subtypes (HLA A0201, A0206 and A0207). The HLA A2-restricted CTL line recognized 9 and 6 different HPLC fractions of peptides eluted from the HLA A0201+ breast and HLA A0201+ colon adenocarcinoma cell lines, respectively. Allele-specific deletion of HLA A2 or A24 molecules was observed in some tumor lines that were not susceptible to lysis by the CTL lines. These results suggest that TIL of gastric cancer possess CTL recognizing different peptide antigens binding to different HLA-A alleles that are widely expressed on adenocarcinomas and also, to some extent, on SCC from different organs.

Abstract
Although CD8+ killer T cells reacting against human autologous tumor cells have recently been studied in detail, little is known about the cytotoxic mechanism of CD4+ T cells against such tumor cells. In order to investigate this, we have established CD4+ cytotoxic T lymphocyte TcOSC-20 lines. TcOSC-20 showed selective cytotoxic activity against autologous OSC-20 cells, derived from a cancer of the tongue, in an HLA-DR-restricted fashion. HLA-DR8 (DRB1*08032) is the only DR molecule expressed on OSC-20 cells, and anti-DR8 monoclonal antibody could inhibit the cytotoxicity, suggesting that HLA-DRB1*08032 is the tumor rejection antigen-presenting molecule to TcOSC-20. The Fas ligand was expressed on TcOSC-20 lines, and its expression was induced upon mixed lymphocyte-tumor cell culture of autologous peripheral blood lymphocytes. Furthermore, the cytotoxicity of TcOSC-20 was inhibited by anti-Fas ligand antibody. These data imply that TcOSC-20 lines recognize the tumor antigenic peptide presented by HLA-DR8, and exert cytotoxicity against autologous tumor cells via a Fas-mediated cytotoxic pathway.

Abstract
The purpose of this study was to determine the feasibility of a vaccine therapy using tumor necrosis factor (TNF) gene-transduced autologous tumor cells for the treatment of human gastrointestinal cancers, which tend to have lower immunogenicity than other cancers such as melanoma and renal cell carcinoma. We succeeded in establishing primary cultured tumor cells from 12/54 carcinomatous effusions (4 liver cancer patients, 5 gastric cancer patients, 1 pancreatic cancer patient, and 2 colon cancer patients) and in transducing the TNF gene to the tumor cells by using the retrovirus vector MFG-TNF. Even after irradiation, TNF production (0.3-3.5 U/ml per 10(6) cells per 72 hr) was confirmed for 10 of 12 transfectants, and the other two transduced cells were found to have approximately one TNF gene copy. In 7 of the 12 patients, the cytotoxic activity of killer cells to nontransduced autologous tumor cells incubated with these TNF gene transfectants was augmented. This activity was blocked with anti-HLA class I antibody or BrefeldinA (BFA), suggesting that the killer cells were cytotoxic T lymphocytes (CTL) and tumor antigens are presented with HLA class I molecules. Indeed, enhanced expression of HLA class I and/or ICAM-1 molecules on the surface of the TNF gene-transduced tumor cells were observed by fluorescence-activated cell sorting (FACS) analysis. Furthermore, natural killer (NK) and/or lymphokine-activated killer (LAK) activities determined by using K562 or Daudi cells as targets were also enhanced in some of these cases when they were incubated with TNF gene-transduced tumor cells. These findings indicate the feasibility of using TNF gene-transduced tumor cells as a vaccine in gastrointestinal cancer patients.
