Abstract
The effects of ionizing radiation to human health are of great concern in the field of space exploration and for patients considering radiotherapy. However, to date, the effect of high-dose radiation on metabolism in the liver has not been clearly defined. In this study, 1H nuclear magnetic resonance (NMR)-based metabolomics combined with multivariate data analysis was applied to study the changes of metabolism in the liver of C57BL/6 mouse after whole-body gamma (3.0 and 7.8 Gy) or proton (3.0 Gy) irradiation. Principal component analysis (PCA) and orthogonal projection to latent structures analysis (OPLS) were used for classification and identification of potential biomarkers associated with exposure to gamma and proton radiation. The results show that the radiation exposed groups can be well separated from the control group. Where the same dose was received, the proton exposed group was nevertheless well separated from the gamma-exposed group, indicating that different radiation sources induce different alterations in the metabolic profile. Common among all high-dose gamma and proton exposed groups were the statistically decreased concentrations of choline, O-phosphocholine and trimethylamine N-oxide, while the concentrations of glutamine, glutathione, malate, creatinine, phosphate, betaine and 4-hydroxyphenylacetate were statistically and significantly elevated. Since these altered metabolites are associated with multiple biological pathways, the results suggest that radiation induces abnormality in multiple biological pathways. In particular, metabolites such as 4-hydroxyphenylacetate, betaine, glutamine, choline and trimethylamine N-oxide may be prediagnostic biomarkers candidates for ionizing exposure of the liver.

Abstract
BACKGROUND & AIMS The hallmarks of hepatic ischemia/reperfusion (I/R) injury, a common clinical problem that occurs during liver surgical procedures, include severe cell death and inflammatory responses that contribute to early graft failure and a higher incidence of organ rejection. Unfortunately, effective therapeutic strategies are limited. Tumor necrosis factor receptor (TNFR)-associated factor (TRAF) 3 transduces apoptosis and/or inflammation-related signaling pathways to regulate cell survival and cytokine production. However, the role of TRAF3 in hepatic I/R-induced liver damage remains unknown. METHODS Hepatocyte- or myeloid cell-specific TRAF3 knockdown or transgenic mice were subjected to an I/R model in vivo, and in vitro experiments were performed by treating primary hepatocytes from these mice with hypoxia/reoxygenation stimulation. The function of TRAF3 in I/R-induced liver damage and the potential underlying mechanisms were investigated through various phenotypic analyses and biological approaches. RESULTS Hepatocyte-specific, but not myeloid cell-specific, TRAF3 deficiency reduced cell death, inflammatory cell infiltration, and cytokine production in both in vivo and in vitro hepatic I/R models, whereas hepatic TRAF3 overexpression resulted in the opposite effects. Mechanistically, TRAF3 directly binds to TAK1, which enhances the activation of the downstream NF-κB and JNK pathways. Importantly, inhibition of TAK1 almost completely reversed the TRAF3 overexpression-mediated exacerbation of I/R injury. CONCLUSIONS TRAF3 is a novel hepatic I/R mediator that promotes liver damage and inflammation via TAK1-dependent activation of the JNK and NF-κB pathways. Inhibition of hepatic TRAF3 may represent a promising approach to protect the liver against I/R injury-related diseases.

Abstract
PURPOSE To investigate the biological effects of titanium ((48)Ti, one of the important heavy ions found in space) in the liver of exposed-mice. MATERIALS AND METHODS We gave adult male CBA/CaJ mice a whole-body exposure to a total dose of 0, 0.1, 0.25 or 0.5 Gy of (48)Ti ions. The liver was collected at 1 week, 1 month, and 6 months post-irradiation (five mice per treatment-group at each harvest-time). Three biological endpoints were used for evaluating the effects of (48)Ti ions: Oxidative-stress, inflammatory responses, and DNA-methylation (5-methylcytosine and 5-hydroxymethylcytosine). RESULTS Our data clearly demonstrated dose-dependent increases in oxidative stress and inflammatory responses in the liver of exposed mice at all time-points (Analysis of Variance or ANOVA, p < 0.05). Significant dose-dependent increases in the levels of 5-methylcytosine were detected at 1 week and 1 month (ANOVA, p < 0.05). At 6 months post-irradiation, a significant increase in the level of 5-methylcytosine was found only in 0.5-Gy-(48)Ti-ion-exposed mice. In contrast, dose-dependent decreases in 5-hydroxymethylcytosine levels were found in the liver of exposed mice (ANOVA, p < 0.05) at all time-points. CONCLUSIONS Chronic oxidative-stress, chronic inflammation, and persistent aberrant DNA-methylation occurred in the liver of (48)Ti-exposed mice. Hence, exposure to (48)Ti ions in space may pose health risks.
