Abstract
Fibrosis is an important pathological mechanism in heart failure (HF) and is associated with poor prognosis. We analyzed fibrosis in HF patients using transcriptomic data. Genes differentially expressed between normal control and congestive HF (CHF) dogs included P3H1, P3H2, P3H4, P4HA2, PLOD1 and PLOD3, which belong to the 2-oxoglutarate-dependent dioxygenases (2OGD) superfamily that stabilizes collagen during fibrosis. Quantitative polymerase chain reaction analysis demonstrated 2OGD gene expression was increased in CHF samples compared with normal left ventricle (LV) samples. 2OGD gene expression was repressed in angiotensin converting enzyme inhibitor-treated samples. These genes, activated the hydroxylation of proline or lysin residues of procollagen mediated by 2-oxoglutaric acid and O2, produce succinic acid and CO2. Metabolic analysis demonstrated the concentration of succinic acid was significantly increased in CHF samples compared with normal LV samples. Fibrosis was induced in human cardiac fibroblasts by TGF-ß1 treatment. After treatment, the gene and protein expressions of 2OGD, the concentration of succinic acid, and the oxygen consumption rate were increased compared with no treatment. This is the first study to show that collagen-related 2OGD genes contribute to HF during the induction of fibrosis and might be potential therapeutic targets for fibrosis and HF.

Abstract
Starvation-resistant renal cell carcinoma (RCC) cell lines are considered dormant-state cells that survive even under glucose starvation. The cellular biological and global transcriptional analysis using these cells identified potential markers of chemotherapy-resistant RCC and therapeutic agent candidates. Recently, we showed that ARL4C was a predictive biomarker for poor prognosis in patients with chemotherapy-resistant RCC by the global transcriptional analysis of patient primary tissues. The objective of this study was to identify the characteristics of chemotherapy-resistant RCC by the global transcriptional analysis of primary tissues of patients with RCC and RCC cell lines. The connective global transcriptional analysis showed that two starvation-resistant RCC cell lines, SW839 and KMRC-1, were strongly correlated to tissues of patients with chemotherapy-resistant RCC and showed high expressions of invasive- and proliferation-related genes. We found fibronectin (FN1) expression was a predictive biomarker in some patients with chemotherapy-resistant RCC, which especially correlated with two starvation-resistant RCC cell lines. These results indicate these cell lines emulate chemotherapy-resistant RCC and might be useful in the search for markers to predict poor prognosis and in the development of therapeutic agents and their index markers for chemotherapy-resistant RCCs.

Abstract
Renal cell carcinoma (RCC) has the high mortality rate among urological malignancies. The development of RCC cannot be effectively reduced by molecular targeted therapies based on nutrient deprivation, such as inhibition of tumor angiogenesis. The objective of this study was to identify predictive biomarkers of poor prognosis and therapeutic molecular targets in patients with RCC. Two independent cohorts were analyzed in the present study. Global transcriptomics were used in the first cohort (43 patients with RCC) to identify biomarker genes. Each identified biomarker was subsequently analyzed using immunohistochemistry in the second cohort (97 patients with RCC). Following transcriptomics, biomarkers were evaluated using receiver operating characteristic curve analysis. Predictive accuracy for poor survivals was assessed using the log-rank test and Cox multivariate analysis. Global transcriptomic analysis in the first cohort focusing on cases with survival periods <2 years after initial diagnosis of metastasis detected seven overexpressed genes, which correlated with poor prognosis. The ADP-ribosylation factor-like 4C (ARL4C) exhibited the best accuracy in the receiver operating characteristic curve analysis and predicted poor survival in the first cohort (log-rank test, P<0.001; Cox multivariate analysis, hazard ratio =167, P=0.005). In the second cohort, the expression of ARL4C was semi-quantitatively evaluated through immunohistochemistry. Twenty-seven cases showed high levels of ARL4C, confirming a significant association with shorter survivals (log-rank test, P<0.001; Cox multivariate analysis, hazard ratio =9.41, P=0.004). ARL4C was shown to be a predictive biomarker for poor prognosis in patients with RCC and may be a novel target in the treatment of RCC.

Abstract
Dormant cancer cells are deprivation-resistant, and cause a number of problems for therapeutic approaches for cancers. Renal cell carcinomas (RCCs) include deprivation-resistant cells that are resistant to various treatments. In this study, the specific characteristics of deprivation-resistant cells were transcriptionally identified by next generation sequencing. The hypoxia-inducible factors (HIF) transcription factor network was significantly enhanced in deprivation-resistant RCCs compared to the sensitive RCCs. Deprivation-resistant RCCs, that had lost Von Hippel-Lindau tumor suppressor expression, expressed hydroxyl-HIF2-alpha in the nucleus, but not sensitive-RCCs. Hydroxyl-HIF-alpha was also expressed in nuclei of RCC tissue samples. Knockdown for HIF2-alpha, but not HIF1-alpha, induced cell death related to a reduction in HIF-related gene expression in deprivation-resistant RCC cells. Chetomin, a nuclear HIF-inhibitor, induced marked level of cytotoxicity in deprivation-resistant cells, similar to the knockdown of HIF2-alpha. Therefore, hydroxyl-HIF2-alpha might be a potential therapeutic target for RCCs.

Abstract
BACKGROUND Phenylketonuria (PKU) is caused by a defect in phenylalanine hydroxylase (PAH). More than 500 mutations have been reported for the gene encoding PAH. However, approximately 1%-5% of these include large deletions and large duplications that cannot be detected by conventional methods. METHODS In this report we tried to fully characterize a PAH-deficient patient. The patient was a 2-year-old Japanese boy who was diagnosed with classical PKU at the time of neonatal screening, which was confirmed by the tetrahydrobiopterin-loading test. PCR-related direct sequencing and multiplex ligation-dependent probe amplification (MLPA) were used to analyze of the PAH of the patient. RESULTS Using PCR-related direct sequencing method, we could detect only a heterozygous novel missense mutation: p.136G>C (p.G46R). A second mutation was detected by MLPA. The patient was heterozygous for a novel large deletion of exons 12 and 13: c.1200-?_1359+?del (EX12_13del). For genetic counseling, an accurate genetic diagnosis is often necessary. CONCLUSIONS Through a combination of MLPA and conventional methods, the success rate of PAH mutation identification can be close to 100%.

Abstract
Cholangiocarcinoma is one of the most serious diseases in northeast Thailand, where its incidence is reported to be the highest in the world. We tried to develop a new method to detect cholangiocarcinoma in the early stages using serum proteins. We found that after fluorescent labeling of the sugar moiety of serum proteins, a new peak was identified, which might be a promising marker for cholangiocarcinoma.

Abstract
Increased levels of N-linked (β-N- acetylglucosamine)2 [N-GlcNAc2]-modified proteins have been recognized to be an effective response to glucose deprivation. In the first step of this study, using a next generation sequencer, we investigated the global transcriptional changes induced by glucose deprivation in a T24 bladder carcinoma cell line, producing N-GlcNAc2-modified proteins under glucose deprivation. Our transcriptome analysis revealed significant up-regulation of the UDP-GlcNAc biosynthesis pathway and unfolded protein response genes, and down-regulation of G2/M transition-related genes containing mitotic kinases. Our biological analysis confirmed that N-GlcNAc2-modified proteins were localized with BiP proteins in the ER. G2/M arrest was caused by glucose deprivation in T24 cells. Moreover, the knockdown of unfolded protein response genes induced the expressional recovery of mitotic kinases under glucose deprivation. Taken together, our results suggest N-GlcNAc2-modified proteins produced under glucose deprivation caused unfolded protein response in the ER, and that this response induced G2/M arrest.

Abstract
Respiratory failure is one of the major causes of death in patients with paraquat poisoning. In paraquat-poisoned lungs, abnormal extracellular matrix regulation occurs. The aim of the present study is to determine whether serum concentrations of type IV collagen and tissue inhibitor of metalloproteinase-1 (TIMP-1) are altered during the course of paraquat poisoning and whether haemoperfusion therapy affects these concentrations. Twenty-one patients were admitted within 3 h after ingestion of paraquat and all patients received direct haemoperfusion therapy. Five out of 21 patients survived and 16 patients died within 28 days. Plasma paraquat concentrations in non-survivors (5740 +/- 380 microg l(-1)) were not significantly different from those in survivors ( 5920 +/- 280 microg l(-1)) before treatment. Haemoperfusion reduced these concentrations in both non-survivors (120 +/- 7 microg l(-1)) as well as survivors (136 +/- 9 microg l(-1)) on day 5. Serum concentrations of type IV collagen and TIMP-1 in survivors showed little change between day 1 (type IV collagen, 90.4 +/- 3.6 ng ml(-1); TIMP-1, 172.2 +/- 7.0 ng ml(-1)) and day 5 (type IV collagen, 92.6 +/- 4.2 ng ml(-1); TIMP-1, 174.2 +/- 7.2 ng ml(-1)). In contrast, these concentrations in non-survivors on day 5 (type IV collagen, 143.6 +/- 7.8 mg ml(-1); TIMP-1, 246.8 +/- 13.6 ng ml(-1)) were significantly higher than those on day 1 (type IV collagen, 88.4 +/- 4.2 ng ml(-1), P < 0.01; TIMP-1, 170.6 +/- 9.2 ng ml(-1), P < 0.05). These data suggest that serum concentrations of type IV collagen and TIMP-1 may be useful indicators for the development of respiratory failure in patients with paraquat poisoning.

Abstract
AIMS The present study assessed whether the serum concentrations of tissue inhibitor of metalloproteinase 1 (TIMP-1) and cytokines are altered in patients with fulminant hepatitis and whether plasma exchange affects these concentrations. METHODS Fifteen patients with fulminant hepatitis, 14 patients with severe acute hepatitis, and 20 healthy controls were included in this study. The serum levels of tumor necrosis factor alpha (TNF-alpha), interleukin 1beta (IL-1beta), interleukin 6 (IL-6), transforming growth factor beta (TGF-beta), and TIMP-1 were determined in all patients upon hospital admission and before and after a single course of plasma exchange in the patients with fulminant hepatitis. RESULTS Ten out of the 15 patients with fulminant hepatitis and all patients with severe acute hepatitis survived. Serum TNF-alpha, IL-6, TGF-beta, and TIMP-1 levels in patients with fulminant hepatitis were significantly higher than the levels in patients with severe acute hepatitis (p < 0.01). IL-1beta was not detectable in either group. Plasma exchange reduced the increased serum concentrations of TNF-alpha, IL-6, TGF-beta, and TIMP-1 in patients with fulminant hepatitis (p < 0.01). CONCLUSIONS These data suggest that increased serum levels of TIMP-1 and cytokines may reflect severe hepatic inflammation and that plasma exchange is an effective therapy to reduce these levels.

Abstract
The 5' untranslated sequence (5' UTS) of platelet-derived growth factor B (PDGF-B/c-sis) mRNA is highly preserved through evolution, and inhibits translation of downstream coding sequences. In this study, using Northern analysis we identified two PDGF-B/c-sis mRNAs (3.5 kb and 2.6 kb) expressed in normal developing rat brain. In contrast to the constitutive expression of 3.5 kb mRNA, the expression of 2.6 kb mRNA increased markedly in accordance with those stages of brain development at which we had previously demonstrated an increased immunoreactivity for PDGF-B/c-SIS in neurons (Sasahara et al., 1992). By PCR cloning and the RNase protection assay, we determined the complete sequence of rat PDGF-B/c-sis, and found that the 2.6 kb transcript was a form of the 3.5 kb message truncated at the 5' end, and that the predominant 2.6 kb mRNA commenced 15 nt upstream of the signal peptide. Accordingly, it is suggested that the truncation of 5' UTS contributes to the expression of PDGF-B/c-SIS protein in the CNS. Lack of translational inhibitory 5' UTS of PDGF-B/c-sis transcript and resultant efficient protein translation have been reported in only a few transformed cells and cultured umbilical vein endothelial cells. We have extended this knowledge to the developing rat brain, and suggest that a similar mechanism could operate widely in non-transformed tissue in vivo.

Abstract
The authors examined the case of an adolescent patient with dissociative identity disorder secondary to psychological shock of a transplant rejection response. Psychiatric symptoms consisted of three components: visual hallucinations and delusions as a psychological defense against the anxiety of a transplant rejection; appearance of three personalities including proper self, the dead child (donor), and a prophet with strong predicting power; and a twilight state. These psychiatric symptoms may have been related to two psychological factors: immature personality characteristics formed during hemodialysis, and post-traumatic stress caused by a chronic rejection reaction from the patient's first transplant.

Abstract
Apical hypertrophic cardiomyopathy, a very common disorder in Japan, is characterized by giant negative T waves on the electrocardiogram and abnormal apical hypertrophy on the ventriculogram. This histocompatibility complexes (HLA-A, -B, -C, -DR) of 20 unrelated patients with apical hypertrophic cardiomyopathy (18 male, 2 female) were examined. There was no significant difference in the frequency of HLA-A, -B, -C antigens between patients and controls (n = 100). However, HLA-DR 2 was more frequent in patients with apical hypertrophic cardiomyopathy (65.0%) than controls (33.0%) (p < 0.01). We conclude that apical hypertrophic cardiomyopathy might be associated with genes in the HLA-DR region and that genetic factors linked to HLA play a role in the pathogenesis of this disease.

Abstract
A 68-year-old woman presented with transverse colon cancer invading the liver, duodenum, and pancreas. The patient underwent a curative resection including a right hemicolectomy, partial hepatectomy, and pancreaticoduodenectomy (PD). The pathological examination showed adenocarcinoma of the colon with a direct extension into the duodenum, liver, and pancreas. Several lymph nodes were also involved. The patient is still alive and disease-free 2 years and 6 months after the operation. This case illustrates that even in patients with locally advanced colon cancer, a favorable prognosis can be obtained by aggressive surgery incorporating the resection of the adjacent involved organs.

Abstract
To evaluate the activation of the sorbitol pathway in cardiac muscle in diabetic rats, we measured sorbitol, fructose, and myo-inositol content in cardiac tissue obtained from control and streptozotocin-diabetic rats, with or without an 8-week insulin treatment, using gas chromatography-mass spectrometry (GC-MS). Cardiac fructose and sorbitol content in 10-week diabetic rats increased by 60-fold and 3.9-fold of those of control rats, respectively (P less than .001). In contrast, cardiac myo-inositol content in 10-week diabetic rats decreased to 56% (P less than .025) of the control value. The abnormalities in cardiac fructose, sorbitol, and myo-inositol content were completely normalized by the 8-week insulin treatment, which was initiated 2 weeks after the induction of diabetes. There was no difference in cardiac aldose reductase activity between control and diabetic rats. However, cardiac sorbitol dehydrogenase activity in diabetic rats was 151% (P less than .005) higher than that of control rats, although hepatic sorbitol dehydrogenase activity was not different between the two groups. These results indicate that the sorbitol pathway is significantly activated in cardiac tissue obtained from streptozotocin-induced diabetic rats, which results in the marked cardiac accumulation of fructose.

Abstract
Mortality, morbidity, liver function and regeneration were evaluated in dogs that had undergone simultaneous major resection of the liver and the pancreas. The 10-week survival rate was only 25% in the dogs that underwent 70% hepatectomy with more than 92% pancreatectomy, and many of them died of liver failure. Long-term survival was observed in more than 60% of the dogs after 70% hepatectomy with less than 92% pancreatectomy or after 40% hepatectomy with more than 92% pancreatectomy. The liver regeneration rate was reduced with the extent of the pancreatectomy, and the reduction was remarkable especially when more than 92% of the pancreas was resected. The frequency of diabetes was reduced when the pancreatectomy was combined with hepatectomy. Hyperlipemia and fatty liver were noted in all the dogs of the group that underwent more than 92% pancreatectomy alone. They were observed also in the postoperative diabetic groups but not in non-diabetic groups. The postoperative recovery of hepatic function and liver regeneration were delayed after simultaneous hepatectomy-pancreatectomy. Also, postoperative carbohydrate and lipid metabolism was better maintained in the hepatectomy-pancreatectomy groups than in the pancreatectomy-alone groups.

Abstract
We screened for foodstuffs affecting interferon-beta (IFN-beta) production of human foreskin diploid fibroblasts, in the presence of poly I.poly C, cycloheximide, and actinomycin D. alpha- and beta-caseins stimulated IFN-beta production dose-dependently, but kappa-casein inhibited it. Of the two chymosin fragments of kappa-casein, glycomacropeptide was an inhibitor but p-kappa-casein was not. beta-lactoglobulin stimulated IFN-beta production weakly, but lactoferrin inhibited it strongly. It was also shown that serum contained some factors inhibiting IFN-beta induction and stimulating its production.

Abstract
Plasma levels of epinephrine which correspond to the arrhythmogenic doses were determined during halothane, enflurane, and pentobarbital anesthesia in the dog. The arrhythmogenic dose was established by a series of 3-min infusion of epinephrine at 10-min intervals. The mean values of the arrhythmogenic doses and the corresponding plasma levels of epinephrine were: 2.18 micrograms X kg-1 X min-1 and 38.7 ng/ml during halothane; 11.43 micrograms X kg-1 X min-1 and 206.3 ng/ml during enflurane; and 15.27 micrograms X kg-1 X min-1 and 296.5 ng/ml during pentobarbital anesthesia. The arrhythmogenic plasma levels of norepinephrine during halothane anesthesia was nearly the same as that of epinephrine.
