| 1 | Anti-inflammatory activity of probiotic Bifidobacterium: Enhancement of IL-10 production in peripheral blood mononuclear cells from ulcerative colitis patients and inhibition of IL-8 secretion in HT-29 cells显示文摘AIM: To determine the anti-inflammatory activity of probiotic Bifidobacteria in Bifidobacteria-fermented milk (BFM) which is effective against active ulcerative colitis (UC) and exacerbations of UC, and to explore the immunoregulatory mechanisms. METHODS: Peripheral blood mononuclear cells (PBMNC) from UC patients or HT-29 cells were co-cultured with heat-killed probiotic bacteria or culture supernatant of Bifidobacterium breve strain Yakult (BbrY) or Bifidobacterium bifidum strain Yakult (BbiY) to estimate the amount of IL-10 or IL-8 secreted. RESULTS: Both strains of probiotic Bifidobacteria contained in the BFM induced IL-10 production in PBMNC from UC patients, though BbrY was more effective than BbiY. Conditioned medium (CM) and DNA of both strains inhibited IL-8 secretion in HT-29 cells stimulated with TNF-α, whereas no such effect was observed with heat- killed bacteria. The inhibitory effect of CM derived from BbiY was greater than that of CM derived from BbrY. DNAs of the two strains had a comparable inhibitory activity against the secretion of IL-8. CM of BbiY induced a repression of IL-8 gene expression with a higher expression of IκB-ζ mRNA 4 h after culture of HT-29 cells compared to that in the absence of CM.CONCLUSION: Probiotic Bifidobacterium strains in BFM enhance IL-10 production in PBMNC and inhibit IL-8 secretion in intestinal epithelial cells, suggesting that BFM has anti-inflammatory effects against ulcerative colitis. | Akemi Imaoka Tatsuichiro Shima Kimitoshi Kato Shigeaki Mizuno Toshiki Uehara Satoshi Matsumoto Hiromi Setoyama Taeko Hara Yoshinori Umesaki | 2008 | World Journal of Gastroenterology2008,14,16: | 37 |
| 2 | Prognostic value of KRAS and BRAF mutations in curatively resected colorectal cancer显示文摘AIM: To investigate the prognostic role of KRAS and BRAF mutations after adjustment for microsatellite instability(MSI) status in Japanese colorectal cancer(CRC) population.METHODS: We assessed KRAS and BRAF mutations and MSI status in 813 Japanese patients with curatively resected, stage Ⅰ-Ⅲ CRC and examined associations of these mutations with disease-free survival(DFS) and overall survival(OS) using uni- and multivariate Cox proportional hazards models.RESULTS: KRAS and BRAF mutations were detected in 312(38%) of 812 and 40(5%) of 811 tumors, respectively. KRAS mutations occurred more frequently in females than in males(P = 0.02), while the presence of BRAF mutations was significantly associated with the female gender(P = 0.006), proximal tumor location(P < 0.001), mucinous or poorly differentiated histology(P < 0.001), and MSI-high tumors(P < 0.001). After adjusting for relevant variables, including MSI status, KRAS mutations were associated with poorer DFS(HR = 1.35; 95%CI: 1.03-1.75) and OS(HR = 1.46; 95%CI: 1.09-1.97). BRAF mutations were poor prognostic factors for DFS(HR = 2.20; 95%CI: 1.19-4.06) and OS(HR = 2.30; 95%CI: 1.15-4.71). Neither the BRAF by MSI interaction test nor the KRAS by MSI interaction test yielded statistically significant results for DFS and OS.CONCLUSION: KRAS and BRAF mutations are associated with inferior survival, independent of MSI status, inJapanese patients with curatively resected CRC. | Shigenori Kadowaki Miho Kakuta Shuhei Takahashi Akemi Takahashi Yoshiko Arai Yoji Nishimura Toshimasa Yatsuoka Akira Ooki Kensei Yamaguchi Keitaro Matsuo Kei Muro Kiwamu Akagi | 2015 | World Journal of Gastroenterology2015,21,4: | 14 |
| 3 | Circulating RNAs as new biomarkers for detecting pancreatic cancer显示文摘Pancreatic cancer remains difficult to treat and has a high mortality rate.It is difficult to diagnose early mainly due to the lack of screening imaging modalities and specific biomarkers.Consequently,it is important to develop biomarkers that enable the detection of early stage tumors.Emerging evidence is accumulating that tumor cells release substantial amounts of RNA into the bloodstream that strongly resist RNases in the blood and are present at sufficient levels for quantitative analyses.These circulating RNAs are upregulated in the serum and plasma of cancer patients,including those with pancreatic cancer,compared with healthy controls.The majority of RNA biomarker studies have assessed circulating microRNAs(miRs),which are often tissue-specific.There are few reports of the tumorspecific upregulation of other types of small noncoding RNAs(ncRNAs),such as small nucleolar RNAs and Piwi-interacting RNAs.Long ncRNAs(IncRNAs),such as HOTAIR and MALAT1,in the serum/plasma of pancreatic cancer patients have also been reported as diagnostic and prognostic markers.Among tissuederived RNAs,some miRs show increased expression even in pre-cancerous tissues,and their expression profiles may allow for the discrimination between a chronic inflammatory state and carcinoma.Additionally,some miRs and IncRNAs have been reported with significant alterations in expression according to disease progression,and they may thus represent potential candidate diagnostic or prognostic biomarkers that may be used to evaluate patients once detection methods in peripheral blood are well established.Furthermore,recent innovations in high-throughput sequencing techniques have enabled the discovery of unannotated tumor-associated ncRNAs and tumor-specific alternative splicing as novel and specific biomarkers of cancers.Although much work is required to clarify the release mechanism,origin of tumor-specific circulating RNAs,and selectivity of carrier complexes,and technical advances must also be achieved,such as creating a consensus normalization protocol for quantitative data analysis,circulating RNAs are largely unexplored and might represent novel clinical biomarkers. | Takahiro Kishikawa Motoyuki Otsuka Motoko Ohno Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Gastroenterology2015,21,28: | 8 |
| 4 | Diagnostic and therapeutic application of noncoding RNAs for hepatocellular carcinoma显示文摘Micro RNAs(mi RNAs) are small,noncoding RNA molecules that regulate gene expression posttranscriptionally,targeting thousands of messenger RNAs. Long noncoding RNAs(lnc RNAs),another class of noncoding RNAs,have been determined to be also involved in transcription regulation and translation of target genes. Since deregulated expression levels or functions of miR NAs and lncR NAs in hepatocellular carcinoma(HCC) are frequently observed,clinical use of noncoding RNAs for novel diagnostic and therapeutic applications in the management of HCCs is highly and emergently e xpe c t e d. H e r e,we s ummar iz e r e c e nt f indings regarding deregulated mi RNAs and lnc RNAs for their potential clinical use as diagnostic and prognostic biomarkers of HCC. Specifically,we emphasize the deregulated expression levels of such noncoding RNAs in patients' sera as noninvasive biomarkers,a field that requires urgent improvement in the clinical surveillance of HCC. Since nucleotide-based strategies are being applied to clinical therapeutics,we further summarize clinical and preclinical trials using oligonucleotides involving the use of miR NAs and small interfering RNAs against HCC as novel therapeutics. Finally,we discuss current open questions,which must be clarified in the near future for realistic clinical applications of these new strategies. | Chikako Shibata Motoyuki Otsuka Takahiro Kishikawa Motoko Ohno Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Hepatology2015,7,1: | 7 |
| 5 | Novel therapeutic approaches for hepatitis B virus covalently closed circular DNA显示文摘Hepatitis B virus(HBV) infection is a major global health problem. Although current therapies, such as the use of nucleos(t)ide analogs, inhibit HBV replication efficiently, they do not eliminate covalently closed circular DNA(ccc DNA), which persists in hepatocyte nuclei. As HBV ccc DNA is a viral transcription template, novel therapeutic approaches to directly target HBV ccc DNA are necessary to completely eradicate persistent HBV infections. HBV ccc DNA levels in HBV-infected human liver cells are extremely low; thus, more reliable and simple measurement methods are needed to correctly monitor their levels during therapeutic treatment. Although reverse transcription-polymerase chain reaction or Southern blot procedures are currently used in research studies, these methods are not completely reliable and are also time-consuming and labor-intensive. Genome editing technologies, such as zinc finger nucleases, transcription activator-like effector nucleases, and the clustered regularly interspaced short palindromic repeats/Cas9(CRISPR/Cas9) system, which are designed to target specific DNA sequences, represent highly promising potential therapeutic tools. In particular, the CRISPR/Cas9 system is an easily customizable sequencespecific nuclease with high flexibility and may be the most feasible approach to target HBV ccc DNA. Further research to develop easier, safer, and more effective protocols should be pursued. | Motoko Ohno Motoyuki Otsuka Takahiro Kishikawa Takeshi Yoshikawa Akemi Takata Kazuhiko Koike | 2015 | World Journal of Gastroenterology2015,21,23: | 5 |
