1The metabolome of induced pluripotent stem cells reveals metabolic changes occurring in somatic cell reprogramming显示文摘新陈代谢对房间功能的每个方面重要,然而,导致的 pluripotent 干细胞(iPSCs ) 的 metabolome 仍然保持大部分未经勘探。这里,我们报导,用一条 untargeted metabolomics 途径,那人的 iPSCs 份额有从他们的父母房间是不同的胚胎的干细胞(转换字符) 的 pluripotent metabolomic 签名,并且那被变化在涉及细胞的呼吸的代谢物描绘。细胞的 bioenergetics 的检查与我们的 metabolomic 分析支持了,并且证明体的房间在 pluripotency 从一个氧化状态变换成一个 glycolytic 状态。有趣地,各种各样的体的房间的 bioenergetics 与他们的 reprogramming 效率相关。我们进一步识别了在 iPSCs 和转换字符之间不同的代谢物,它揭示了在调整体的房间 reprogramming 起一个关键作用的新奇新陈代谢的小径。我们的调查结果是第一全球性分析 iPSCs 的 metabolome,并且提供机械学的卓见进涉及导致 pluripotency,并且在评估 iPSC 和转换字符等价的规定的新层。Athanasia D Panopoulos Oscar Yanes Sergio Ruiz Yasuyuki S Kida Dinh Diep Ralf Tautenhahn Aida Herrerias Erika M Batchelder Nongluk Plongthongkum Margaret Lutz W Travis Berggren Kun Zhang Ronald M Evans Gary Siuzdak Juan Carlos Izpisua Belmonte] 2012Cell Research2012,22,1:12

3Adjuvant therapy sparing in rectal cancer achieving complete response after chemoradiation显示文摘AIM:To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy.METHODS:Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of 5-fluorouracil for five weeks and concomitant radiotherapy.Laparoscopic surgery was planned after 5-8 wk.Patients diagnosed with ypT0N0 stage cancer were not treated with adjuvant therapy according to the protocol.Patients with ypT1-2N0 or ypT3-4 or N+were offered 5-fluorouracil-based adjuvant treatment on an individual basis.An external cohort was used as a reference for the findings.RESULTS:One hundred and seventy six patients were treated with induction chemoradiotherapy and 170underwent total mesorectal excision.Cancer staging of ypT0N0 was achieved in 26/170(15.3%)patients.After a median follow-up of 58.3 mo,patients withypT0N0 had five-year disease-free and overall survival rates of 96%(95%CI:77-99)and 100%,respectively.We provide evidence about the natural history of patients with localized rectal cancer achieving a complete response after preoperative chemoradiation.The inherent good prognosis of these patients will have implications for clinical trial design and care of patients.CONCLUSION:Withholding adjuvant chemotherapy after complete response following standard neoadjuvant chemoradiotherapy and laparoscopic mesorectal excision might be safe within an experienced multidisciplinary team.Xabier García-Albéniz Rosa Gallego Ralf Dieter Hofheinz Gloria Fernández-Esparrach Juan Ramón Ayuso-Colella Josep Antoni Bombí Carles Conill Miriam Cuatrecasas Salvadora Delgado Angels Ginés Rosa Miquel Mario Pagés Estela Pineda Verónica Pereira Aarón Sosa Oscar Reig Iván Victoria Luis Feliz Antonio María de Lacy Antoni Castells Iris Burkholder Andreas Hochhaus Joan Maurel 2014World Journal of Gastroenterology2014,20,42:5

5Enhanced expression of interleukin-18 in serum and pancreas of patients with chronic pancreatitis显示文摘AIM: To investigate interleukin-18 (IL-18) in patients with chronic panreatitis (CP). METHODS: We studied 29 patients with CP and 30 healthy controls. Peripheral blood mononuclear cells (PBMC) were isolated and incubated with 50 mmol/L ethanol, lipopolysaccharide (LPS) (doses 25 g/L, 250 g/L, 2500 g/L) and both agents for 24 h. Levels of IL-18 in the supernatants, and levels of IL-18, IL-12, interferon (IFN)-γ and soluble CD14 in the serum were analysed by ELISA technique. Expression of IL-18 in PBMC was investigated by reverse-transcription (RT)-PCR. IL-18 protein levels in CP tissue and in normal pancreas were studied by ELISA technique. IL-18 levels in PBMC and pancreatic tissue were determined by Westernblot. Im-munohistochemistry for pancreatic IL-18 expression was performed. RESULTS: In patients, IL-18 serum levels were signifi-cantly enhanced by 76% (mean: 289.9 ± 167.7 ng/L) compared with controls (mean: 165.2 ± 43.6 ng/L; P < 0.0005). IL-12 levels were enhanced by 25% in patients (18.3 ± 7.3 ng/L) compared with controls (14.7 ± 6.8ng/L, P = 0.0576) although not reaching the statistical significance. IFN-γ and soluble CD14 levels were not in-creased. In vitro, LPS stimulated significantly and dose-dependently IL-18 secretion from PBMC. Incubation with ethanol reduced LPS-stimulated IL-18 secretion by about 50%. The mRNA expression of IL-18 in PBMC and the response of PBMC to ethanol and LPS was similar in CP patients and controls. In PBMC, no significant differences in IL-18 protein levels were detected between patients and controls. IL-18 protein levels were increased in CP tissues compared to normal pancreatic tissues. IL-18 was expressed by pancreatic acinar cells and by infiltrating inflammatory cells within the pancreas. CONCLUSION: IL-18 originates from the chronically inflammed pancreas and appears to be involved in the fibrotic destruction of the organ.Alexander Schneider Stephan L Haas Ralf Hildenbrand Sren Siegmund Iris Reinhard Helmut Nakovics Manfred V Singer Peter Feick 2006World Journal of Gastroenterology2006,12,40:4
