Abstract
Triple-negative breast cancer (TNBC) chemoresistance hampers the ability to effectively treat patients. Identification of mechanisms driving chemoresistance can lead to strategies to improve treatment. Here, we revealed that protein arginine methyltransferase-1 (PRMT1) simultaneously methylates D-3-phosphoglycerate dehydrogenase (PHGDH), a critical enzyme in serine synthesis, and the glycolytic enzymes PFKFB3 and PKM2 in TNBC cells. 13C metabolic flux analyses showed that PRMT1-dependent methylation of these three enzymes diverts glucose toward intermediates in the serine-synthesizing and serine/glycine cleavage pathways, thereby accelerating the production of methyl donors in TNBC cells. Mechanistically, PRMT1-dependent methylation of PHGDH at R54 or R20 activated its enzymatic activity by stabilizing 3-phosphoglycerate binding and suppressing polyubiquitination. PRMT1-mediated PHGDH methylation drove chemoresistance independently of glutathione synthesis. Rather, activation of the serine synthesis pathway supplied α-ketoglutarate and citrate to increase palmitate levels through activation of fatty acid synthase (FASN). Increased palmitate induced protein S-palmitoylation of PHGDH and FASN to further enhance fatty acid synthesis in a PRMT1-dependent manner. Loss of PRMT1 or pharmacologic inhibition of FASN or protein S-palmitoyltransferase reversed chemoresistance in TNBC. Furthermore, IHC coupled with imaging MS in clinical TNBC specimens substantiated that PRMT1-mediated methylation of PHGDH, PFKFB3, and PKM2 correlates with chemoresistance and that metabolites required for methylation and fatty acid synthesis are enriched in TNBC. Together, these results suggest that enhanced de novo fatty acid synthesis mediated by coordinated protein arginine methylation and protein S-palmitoylation is a therapeutic target for overcoming chemoresistance in TNBC. SIGNIFICANCE PRMT1 promotes chemoresistance in TNBC by methylating metabolic enzymes PFKFB3, PKM2, and PHGDH to augment de novo fatty acid synthesis, indicating that targeting this axis is a potential treatment strategy.

Abstract
This study aimed to establish an exposure method that can induce homogeneous lesions with minimal inter-individual variability. The distribution of lesions induced by bleomycin (BLM) administration was also analyzed. C57BL mice were intrabronchially administered 20 µL of BLM (3 mg/mL) using a bronchoscope in the left or right bronchus. The mice were sacrificed 14 days after administration, and their lungs were evaluated histopathologically. BLM-induced inflammatory lesions were widely observed in the lungs. In the left bronchus-treated group, lesions were uniformly observed throughout the lobe, and no individual differences were noted. Meanwhile, in the right bronchus-treated group, individual differences in the distribution of the pulmonary lesions were observed. The distribution of lesions differed among the four lobes of the right lung owing to their anatomical features. Administration into the left bronchus is recommended for highly homogeneous lung exposure and for establishing models that contribute to highly accurate toxicity and efficacy evaluations.

Abstract
The development of regenerative medicine using cell therapy is eagerly awaited for diseases such as spinal cord injury (SCI), for which there has been no radical cure. We previously reported the direct conversion of human fibroblasts into neuronal-like cells using only chemical compounds; however, it is unclear whether chemical compound-induced neuronal-like (CiN) cells are clinically functional. In this study, we partially modified the method of inducing CiN cells (termed immature CiN cells) and examined their therapeutic efficacy, in a rat model of SCI, to investigate whether immature CiN cells are promising for clinical applications. Motor function recovery, after SCI, was assessed using the Basso, Beattie, and Bresnahan (BBB) test, as well as the CatWalk analysis. We found that locomotor recovery, after SCI in the immature CiN cell-transplanted group, was partially improved compared to that in the control group. Consistent with these results, magnetic resonance imaging (MRI) and histopathological analyses revealed that nerve recovery or preservation improved in the immature CiN cell-transplanted group. Furthermore, transcriptome analysis revealed that immature CiN cells highly express hepatocyte growth factor (HGF), which has recently been shown to be a promising therapeutic agent against SCI. Our findings suggest that immature CiN cells may provide an alternative strategy for the regenerative therapy of SCI.

Abstract
Neutrophils are critical mediators during the early stages of innate inflammation in response to bacterial or fungal infections. A human hematopoietic system reconstituted in humanized mice aids in the study of human hematology and immunology. However, the poor development of human neutrophils is a well-known limitation of humanized mice. Here, we generate a human granulocyte colony-stimulating factor (hG-CSF) knockin (KI) NOD/Shi-scid-IL2rgnull (NOG) mouse in which hG-CSF is systemically expressed while the mouse G-CSF receptor is disrupted. These mice generate high numbers of mature human neutrophils, which can be readily mobilized into the periphery, compared with conventional NOG mice. Moreover, these neutrophils exhibit infection-mediated emergency granulopoiesis and are capable of efficient phagocytosis and reactive oxygen species production. Thus, hG-CSF KI mice provide a useful model for studying the development of human neutrophils, emergency granulopoiesis, and a potential therapeutic model for sepsis.

Abstract
BACKGROUND/AIM The present study assessed whether and how tumor cells undergoing hypoxia contribute to disease progression after moving to areas with different oxygen conditions. MATERIALS AND METHODS Human colorectal carcinoma HCT116 cells cultured under mild hypoxia were subjected to in vivo experiments using transfer to immunodeficient murine recipients and to in vitro experiments using pharmacological inhibition of fatty acid β-oxidation (FAO). RESULTS Bone involvement and hepatic metastases were accelerated in transfer models of hypoxically cultured HCT116 cells. Hypoxic HCT116 cells exhibited FAO-dependent glycogen synthesis. FAO-dependent and -independent induction of gene expression also occurred under hypoxia. The distribution of glucose transporter 1 expression compared with heme oxygenase 1 expression in HCT116 cell spheroids seemed consistent with differential dependence of hypoxic expression of these molecules on FAO. CONCLUSION These results provide insights into the contribution of hypoxia to tumor progression and the relevance of FAO.

Abstract
We investigated the viability of a combined repeated dose toxicity study, including toxicokinetics (TK), in common marmosets according to the ICH-S4, ICH-S3A and ICH-S7A Guidelines using valsartan as test article whose non-clinical repeated dose toxicity studies had been conducted using this species for regulatory purpose. Valsartan was administered orally to 3 animals/sex at 200 mg/kg/day for 2 weeks. In addition to the routine parameters in repeated dose toxicity studies, safety pharmacology parameters (examinations of the central nervous, respiratory and cardiovascular systems) were also evaluated. The Plasma Micro Sampling Toxicokinetics (PMS-TK) method required ultrasensitive quantitation, was employed to evaluate the relationship between toxic changes and plasma concentrations as well as the effects of frequent blood sampling in individual animals. In valsartan, toxic findings (a deteriorated physical condition; moribundity of one male and one female on Day 14; sporadic vomitus; decreases in body weights and food consumption; decreases in erythrocytic parameters; and renal changes such as an increase in urea nitrogen, dilation of the tubules and hypertrophy of the tubular epithelium) were similar and plasma concentrations comparable to the results in the approval information. Furthermore, no side effects caused by frequent blood sampling were confirmed in the negative control group. Consequently, a combined repeated dose toxicity study including TK analysis using the PMS-TK method is viable in common marmosets and contributes to animal welfare.

Abstract
We generated a novel mouse strain expressing transgenic human interleukin-15 (IL-15) using the severe immunodeficient NOD/Shi-scid-IL-2Rγnull (NOG) mouse genetic background (NOG-IL-15 Tg). Human natural killer (NK) cells, purified from the peripheral blood (hu-PB-NK) of normal healthy donors, proliferated when transferred into NOG-IL-15 Tg mice. In addition, the cell number increased, and the hu-PB-NK cells persisted for 3 months without signs of xenogeneic graft versus host diseases (xGVHD). These in vivo-expanded hu-PB-NK cells maintained the original expression patterns of various surface antigens, including NK receptors and killer cell immunoglobulin-like receptor (KIR) molecules. They also contained significant amounts of granzyme A and perforin. Inoculation of K562 leukemia cells into hu-PB-NK-transplanted NOG-IL-15 Tg mice resulted in significant suppression of tumor growth compared with non-transplanted mice. Furthermore, NOG-IL-15 Tg mice allowed for engraftment of in vitro-expanded NK cells prepared for clinical cell therapy. These cells exerted antibody-dependent cell-mediated cytotoxicity (ADCC) on Her2-positive gastric cancer cells in the presence of therapeutic anti-Her2 antibody, and subsequently suppressed tumor growth. Our results collectively suggest that the NOG-IL-15 Tg mice are a useful model for studying human NK biology and evaluating human NK cell-mediated in vivo cytotoxicity.

Abstract
INTRODUCTION Heat-denatured 99mTc-labeled red blood cells (RBCs) are used for detecting splenic tissues with scintigraphy. The present study aimed to evaluate the feasibility of using heat-denatured [18F]fluorodeoxyglucose ([18F]FDG)-labeled RBCs in detecting splenic tissues using positron emission tomography (PET) in rats. METHODS RBCs were washed with phosphate buffered saline, labeled with [18F]FDG at 38°C, and heat-denatured at 50°C for 15 min. In vitro stability was assessed by measuring extracellular radioactivity during the 0-180 min incubation at 37°C. Thin layer chromatography (TLC) of the extracellular fluid was performed. The autologous RBCs were intravenously injected in four rats and PET scanning was simultaneously performed for 30 min. Time-activity curves of several organs, including the spleen, were analyzed on the PET images. RESULTS Labeling efficiency was 92%. Low levels of radioactivity were released from the labeled RBCs for 180 min. TLC revealed that 80% of the released radioactivity was due to [18F]FDG-6-phosphate. Whole body images showed strong uptake of heat-denatured [18F]FDG-labeled RBCs in the spleen soon after injection in all four rats. Time-activity curves revealed that the splenic uptake continued to increase for 30 min and the amount of radioactivity in the other organs, except the urinary bladder, decreased after the initial surge. CONCLUSIONS Heat-denatured [18F]FDG-labeled RBCs are suitable spleen-specific agents for PET. This method is clinically relevant as an alternative for heat-denatured 99mTc-labeled RBC scintigraphy.

Abstract
Background Red blood cells (RBCs) labeled with single-photon emitters have been clinically used for blood-pool imaging. Although some PET tracers have been introduced for blood-pool imaging, they have not yet been widely used. The present study investigated the feasibility of labeling RBCs with 18F-2-deoxy-2-fluoro-D-glucose (18F-FDG) for blood-pool imaging with PET. RBCs isolated from venous blood of rats were washed with glucose-free phosphate-buffered saline and labeled with 18F-FDG. To optimize labeling efficiency, the effects of glucose deprivation time and incubation (labeling) time with 18F-FDG were investigated. Post-labeling stability was assessed by calculating the release fraction of radioactivity and identifying the chemical forms of 18F in the released and intracellular components of 18F-FDG-labeled RBCs incubated in plasma. Just after intravenous injection of the optimized autologous 18F-FDG-labeled RBCs, dynamic PET scans were performed to evaluate in vivo imaging in normal rats and intraabdominal bleeding models (temporary and persistent bleeding). Results The optimal durations of glucose deprivation and incubation (labeling) with 18F-FDG were 60 and 30 min, respectively. As low as 10% of 18F was released as the form of 18F-FDG from 18F-FDG-labeled RBCs after a 60-min incubation. Dynamic PET images of normal rats showed strong persistence in the cardiovascular system for at least 120 min. In the intraabdominal bleeding models, 18F-FDG-labeled RBC PET visualized the extravascular blood clearly and revealed the dynamic changes of the extravascular radioactivity in the temporary and persistent bleeding. Conclusions RBCs can be effectively labeled with 18F-FDG and used for blood-pool imaging with PET in rats.

Abstract
Liver metastases of colorectal cancers significantly affect the prognoses of patients. To further understand the biological aspects of the metastatic phenotypes, we established the highly liver-metastatic human colorectal cancer cell subline SW48LM2. The subline was established through the serial intrasplenic transfer of cells derived from poor but visible hepatic tumor foci formed by parental SW48 cells and transferred to NOD/SCID/IL-2Rγc(null) mice. The growth, both under monolayer culture conditions and during the formation of subcutaneous tumors, was similar between the two cell lines, although there were morphological differences in the in vitro spheroid formation. Of 41 molecules reportedly associated positively or negatively with tumor progression, four were overexpressed and four were underexpressed in SW48LM2 cells. Notably, this liver-metastatic cell subline exhibited a strongly reduced expression of the ecto-5'-nucleotidase CD73 as well as an altered metabolism of purine nucleotides. Previous studies showed a positive correlation between CD73 expression and metastatic cancer phenotypes. A reduced CD73 expression in tumor cells, however, may contribute to obtaining insight into the mechanisms of liver metastases.

Abstract
Abstract
There have been a number of reports mentioning the significance of adaptation of cancer cells to hypoxic environments in tumor growth, invasion, and metastases. However, understanding of molecular aspects based on in vivo evidence still remains insufficient. We established an in vivo tumor progression model by transfer of human colorectal cancer HCT116 cells cultured under hypoxia to NOD/Shi-scid, IL-2Rγnull (NOG) mouse recipients. The hypoxic culture resulted in invasive proliferation of subcutaneous tumors. Immnohistochemical staining for molecular markers, such as E-cadherin, vimentin and BCRP1, demonstrated that adaptation of HCT116 cells to hypoxia was associated with increased frequencies of epithelial-mesenchymal transition and cancer stem cell-like appearance. To investigate the molecular basis of such effects of hypoxia on tumor progression, biological and molecular profiles of HCT116 cultured under hypoxia were analyzed. The hypoxic culture resulted in slowing cell cycling and increase in the side population cell frequency, suggesting induction of stemness. Capillary electrophoresis-mass spectrometric analysis revealed altered metabolism in hypoxic HCT116 cells, which appeared to be associated with adaptation to hypoxia. Gene expression profiling of the cultured cells under pharmacological inhibition of p53, which is not mutated in HCT116 cells, presented evidence for dependence of the adaptation to chronic mild but not acute severe hypoxia on p53 function. Our results provided insights into molecular basis of tumor progression critically directed by hypoxia.

Abstract
We aimed to examine metabolism of human cancer in vivo and utilized superimmunodeficient NOG mice as an experimental model of hepatic metastasis, where human colon cancer cell line HCT116 transfected with Venus, the mutant GFP was injected intrasplenically. The mice were pretreated with Pd-porphyrin to quantify local O(2) tension through intravital phosphorescence assay. In this model, a majority of metastatic foci occurred in periportal regions but not in central regions. At 1 week after the transplantation, a PO(2) drop in periportal regions was minimal without any notable decrease in microvascular blood flow. Under these conditions, there was a negative correlation between the size of metastatic foci and the lobular O(2) consumption, suggesting that the tumor O(2) consumption is smaller than that in the residual liver. At 2 weeks, portal PO(2) was significantly smaller than controls, while the central PO(2) was not comparably decreased, indicating that metastatic foci increased the O(2) consumption, while the residual liver decreased it. These results suggest metastatic tumors derived from human colon cancer exhibit notable aerobic metabolism during their developmental process, compromising respiration of the rest of the tissue regenerated during tumor development.

Abstract
Thrombospondin (TSP) 2 interacts with matrix metalloproteinases (MMPs) and matrix serine proteases such as plasminogen activator (PA). Malignant melanoma is an aggressive human neoplasm showing aggressive metastatic features. We examined the effects of TSP2 gene introduction in the human malignant melanoma cell line A375. We established three clones transfected with human TSP2 (A375/TSP2). The in vitro invasiveness was remarkably suppressed (42-61%) in the TSP2-transfectants, while growth properties were preserved. The A375/TSP2 showed significantly decreased liver metastatic potential (liver weight: 3.88+/-0.30 g in A375/TSP2, 7.07+/-0.67 g in vector-transfectant (A375/V), p<0.01, Mann-Whitney U test) in super immuno-deficient mice (NOD/SCID/gammacnull, NOG). The PA inhibitor-1 (PAI-1) and PAI-2 mRNAs were significantly overexpressed in A375/TSP2. The increased activities of PAI-1 and PAI-2 were confirmed by reverse zymography. The vascularity of metastatic lesions was significantly decreased in A375/TSP2 (vascular density: 0.62+/-0.15% in A375/TSP2, 4.96+/-0.61% in A375/V, p<0.01, Welch test). These results suggest that TSP2 suppresses hematogenous metastasis through microenvironment-modification including PAI up-regulation and anti-vascularization in human malignant melanoma.

Abstract
The transmembrane chemokine CXCL 16 (CXCL16), which is the same molecule as the scavenger receptor that binds phosphatidylserine and oxidized lipoprotein (SR-PSOX), has been shown to mediate chemotaxis and adhesion of CXC chemokine receptor 6-expressing cells such as NKT and activated Th1 cells. We generated SR-PSOX/CXCL16-deficient mice and examined the role of this chemokine in vivo. The mutant mice showed a reduced number of liver NKT cells, and decreased production of IFN-gamma and IL-4 by administration of alpha-galactosylceramide (alphaGalCer). Of note, the alphaGalCer-induced production of IFN-gamma was more severely impaired than the production of IL-4 in SR-PSOX-deficient mice. In this context, SR-PSOX-deficient mice showed impaired sensitivity to alphaGalCer-induced anti-tumor effect mediated by IFN-gamma from NKT cells. NKT cells from wild-type mice showed impaired production of IFN-gamma, but not IL-4, after their culture with alphaGalCer and APCs from mutant mice. Moreover, Propionibacterium acnes-induced in vivo Th1 responses were severely impaired in SR-PSOX-deficient as well as NKT KO mice. Taken together, SR-PSOX/CXCL16 plays an important role in not only the production of IFN-gamma by NKT cells, but also promotion of Th1-inclined immune responses mediated by NKT cells.

Abstract
To examine the drug efficacy of a novel farnesyltransferase inhibitor (FTI), CH4512600, in vivo, we developed a reliable liver metastasis model of human colon cancer using NOD/Shi-scid IL2Rgamma(null) (NOG) mice. Eleven human colon cancer cell lines were examined for their ability to form diverse metastatic foci in the livers of NOG mice. When inoculated with 10(4) COLO320DM, HCT 116, HT-29, WiDr, LoVo and LS174T cells, liver metastasis was evident in 100% (6/6), 100% (6/6), 88.9% (8/9), 87.5% (7/8), 83.3% (5/6) and 50.0% (3/6) of the NOG mice, respectively. CaCo2, COLO201, LS123, SW48 and SW1417 showed no metastasis when seeded at 10(4) cells even in NOG mice. The mRNA expression levels and genetic mutations of N, H and K-RAS genes, which directly affect the levels of cellular RAS protein that would be molecular target for FTI, were also examined in these six metastatic human colon cancer cell lines for molecular biological and genotypic characteristics. Only three cell lines had a point mutation in the RAS oncogene. LS174T cell line had a point mutation of the K-RAS gene at codon 12 (gly12 --> asp; G12D), and HCT 116 and LoVo cell lines had a point mutation of the K-RAS gene at codon 13 (gly13 --> asp; G13D). Relative gene expression levels of N, H and K-RAS genes in the HCT 116 cell line were 2.6-5.0-fold lower than that of LS174T and LoVo cell lines. We selected HCT 116 cell line from our liver metastasis model for evaluation of FTI CH4512600 efficacy in vivo. Using the NOG mouse liver metastasis model, we demonstrated the effectiveness of FTI CH4512600 to suppress tumor growth in vivo and to prolong mouse survival significantly from 36.9+/-2.9 to 50.3+/-9.4 days.

Abstract
The GB-04-JCK xenograft line of human gallbladder small cell carcinoma was established in nude mice by serial transplantation. The xenotransplantability has been maintained for more than 20 years. The carcinoma cells grew in a solid-sheet pattern and were found to have hyperchromatic nuclei, finely dispersed chromatin and inconspicuous nucleoli in the primary gallbladder tumor, as well as in the established xenograft GB-04-JCK The carcinoma cells also had Grimelius argyrophil granules, electron-dense neuroendocrine granules bounded by a single membrane. The xenograft line retained histological and immunohistochemical characteristics of the primary gallbladder tumor and is the first reported xenotransplantable tumor of human gallbladder small cell carcinoma.

Abstract
Glutamate cysteine ligase (GCL) is a key enzyme in glutathione (GSH) synthesis, and is thought to play a significant role in the intracellular detoxification of anticancer drugs, especially of cisplatin (CDDP). GCL is composed of a modifier or light chain subunit (GCLM) and a catalytic or heavy chain subunit (GCLC). It was unclear whether the subunits are essential to CDDP-resistance. We examined the gene expression of GCLM and GCLC in 39 xenografts of human non-small cell lung cancer [NSCLC; 10 adenocarcinoma (Ad), 17 squamous cell carcinoma (Sq) and 12 large cell carcinoma (La)] by real-time polymerase chain reaction (PCR) with human-specific primers. Drug sensitivity to CDDP was evaluated in the 9 xenografts (4 Ad, 2 Sq and 3 La) using an in vivo drug sensitivity test. There was a significant association between the expression of GCLM and GCLC mRNA in each xenograft (Fisher's test, p<0.045). Squamous cell carcinoma xenografts significantly showed higher expression of GCLM gene than adenocarcinoma xenografts (p=0.023, t-test), while there was no significant difference in GCLC gene expression levels between each histopathological xenograft. Three of nine xenografts were sensitive to CDDP (Mann-Whitney U test, p<0.01, one-sided), while the other 6 xenografts were resistant. There was a significant relationship between drug sensitivity to CDDP and the co-overexpression of GCL subunits (chi2 test for independence, Yates' correction, p=0.014). These results suggested that the co-overexpression of GCL subunits correlated with CDDP-resistance in human NSCLC xenograft in vivo.

Abstract
To date, no single or multiple molecular markers have been successful in predicting sensitivity of individual patients to anti-cancer drugs. As the nature of a specific cancer is considered to be defined by the proteins being expressed in the tumor cells, systematic analysis of gene-expression profiles may provide information reflecting sensitivity of a given tumor to certain drugs. Recent progress in genome technology has enabled us to examine expression profiles of thousands of genes in a single experiment. We used this approach to examine 13 xenografts of human tumors implanted into nude mice for sensitivity to an orally active, selective epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), ZD1839 (Iressa). To identify genes that might be associated with sensitivity to this drug we used a cDNA microarray representing 23,040 genes to analyze expression profiles of the 13 xenografts and identified 114 genes whose expression levels correlated significantly with sensitivity of the tumors to ZD1839. We then investigated alteration of expression profiles in response to the ZD1839 treatment in four non-small cell lung cancer (NSCLC) xenografts, of which two (LC6 and LC11) were sensitive and the other two (Lu116 and L27) were resistant to this EGFR-TKI. Systematic analysis of expression at various time points during oral treatment for 14 days, compared with corresponding untreated samples, identified a set of genes whose expression levels changed in the two sensitive tumors but not in the two resistant tumors. The data obtained here should provide useful information on the molecular mechanism underlying clinical responses to EGFR-TKIs, aid the development of novel therapies for lung cancer, and potentially identify predictive molecular markers for sensitivity to ZD1839.
