Abstract
The curdlan gel is a natural material produced by bacteria. It utilizes chemical cross-linking reactions to form a 3D porous composite hydrogel, increasing its porosity and water content, and improving its mechanical properties. It can be used in tissue repair and regenerative medicine. Curdlan-Poly(vinyl alcohol) (PVA) composite hydrogel can rapidly swell within 1 min due to its porous structure. Compression tests confirmed that it still maintains its original mechanical strength, even after five repeated freeze-thaw (FT) processes, making it suitable for long-term cryopreservation. The purpose of this study is to transplant umbilical cord mesenchymal stem cells (UC-MSCs) on Curdlan-PVA composite hydrogel and observe the chondrocytes on the material. The results of using 4',6-diamidino-2-phenylindole (DAPI), hematoxylin and eosin (H&E), calcein-acetoxymethyl ester (calcein AM), and Collagen type II-Fluorescein isothiocyanate (FITC) staining, confirmed that UC-MSCs can attach and differentiate into chondrocytes on 3D Curdlan-PVA composite hydrogel.

Abstract
Neuroblastomas are the most common extracranial solid tumors in children and have a unique feature of neuronal differentiation. Peroxisome proliferator-activated receptor (PPAR)-γ is reported to have neuroprotective effects in addition to having antitumor effects in various cancers. Thus, we aimed to clarify the role of PPAR-γ agonist and antagonist in malignant neuroblastomas, which also possess neuronal features. In MYCN-amplified neuroblastoma CHP212 cells, treatment with the PPAR-γ antagonist GW9662 induced growth inhibition in a dose-dependent manner. In addition, the PPAR-γ antagonist treatment changed cell morphology with increasing expression of the neuronal differentiation marker tubulin beta 3 (TUBB3) and induced G1 phase arrest and apoptosis in MYCN-amplified neuroblastoma. Notably, the PPAR-γ antagonist treatment significantly decreased expression of NMYC, B-cell lymphoma 2 (BCL2) and bromodomain-containing protein 4 (BRD4). It is implied that BRD4, NMYC, BCL2 suppression by the PPAR-γ antagonist resulted in cell growth inhibition, differentiation, and apoptosis induction. In our in vivo study, the PPAR-γ antagonist treatment induced CHP212 cells differentiation and resultant tumor growth inhibition. Our results provide a deeper understanding of the mechanisms of tumor cell differentiation and suggest that PPAR-γ antagonist is a new therapeutic and prevention option for neuroblastomas.

Abstract
BACKGROUND/AIM Among colorectal cancer-associated intestinal microbiota, colibactin-producing (clb+) bacteria are attracting attention. We aimed to clarify the interaction between clb+ Escherichia coli and normal colorectal epithelial cells in vivo and in vitro. MATERIALS AND METHODS Five-week-old female Balb/c mice were divided in an untreated group, a group treated with clb+ E. coli isolated from a Japanese patient with colorectal cancer (E. coli-50), and a group treated with non colibactin-producing E. coli (E. coli-50/ΔclbP). Mice were sacrificed at 18 weeks of treatment. RESULTS Treatment with clb+ E. coli increased positivity for H2A histone family member X phosphorylated at Ser-139 (γH2AX) in epithelial cells of the luminal surface of the mouse rectum but this did not occur in the E. coli-50/ΔclbP and untreated groups. In an in vitro setting, the ratio of apoptotic cells was increased and cell counts were reduced by treatment with clb+ E. coli more than in untreated cells and normal rat colorectal epithelial cells. CONCLUSION E. coli-50 induced DNA damage in the mouse rectum, possibly by direct interaction between clb+ E. coli and normal colorectal epithelial cells. Our findings imply that regulation of clb+ E. coli infection may be a useful strategy for colorectal cancer control.

Abstract
As colon cancer is one of the most common cancers in the world, practical prevention strategies for colon cancer are needed. Recently, treatment with aspirin and/or 5-aminosalicylic acid-related agents was reported to reduce the number of intestinal polyps in patients with familial adenomatous polyposis. To evaluate the mechanism of aspirin and 5-aminosalicylic acid for suppressing the colon polyp growth, single and combined effects of 5-aminosalicylic acid and sodium salicylate (metabolite of aspirin) were tested in the two human colon cancer cells with different cyclooxygenase-2 expression levels and intestinal polyp-derived cells from familial adenomatous polyposis model mouse. The combination induced cell-cycle arrest at the G1 phase along with inhibition of cell growth and colony-forming ability in these cells. The combination reduced cyclin D1 via proteasomal degradation and activated retinoblastoma protein. The combination inhibited the colony-forming ability of mouse colonic mucosa cells by about 50% and the colony-forming ability of mouse intestinal polyp-derived cells by about 90%. The expression level of cyclin D1 in colon mucosa cells was lower than that in intestinal polyp-derived cells. These results suggest that this combination may be more effective in inhibiting cell growth of intestinal polyps through cyclin D1 down-regulation.

Abstract
BACKGROUND/AIM Οverweight and obesity are risk factors for chronic diseases. Dietary calcium has been reported to exert anti-obesity effects. However, the complex modulating effects of calcium intake on obese mice have not been clarified. MATERIALS AND METHODS The effects of calcium intake on body weight/visceral fat mass were examined in the obese mouse model, KK-Ay Results: Body weight gain decreased in mice fed a diet containing 0.4 to 3.2% calcium at the age of 11 and 13 weeks, but not at 12 weeks after normalization for food intake. Calcium intake also decreased serum insulin levels and increased the amount of feces excreted. Fecal deoxycholate levels were lower in the high-calcium group than in the normal diet control group. Furthermore, the ratio of the deoxycholate-producing microbiome in feces decreased. CONCLUSION Dietary calcium has anti-obesity effects in obese KK-Ay mice. Inhibition of insulin production and an increased amount of feces excreted with calcium intake may affect body weight.

Abstract
Artesunate (ART) is a clinically approved antimalarial drug and was revealed as a candidate of colorectal cancer chemopreventive agents in our drug screening system. Here, we aimed to understand the suppressive effects of ART on intestinal tumorigenesis. In vitro, ART reduced T-cell factor/lymphoid enhancer factor (TCF/LEF) promoter transcriptional activity. In vivo, ART inhibited intestinal polyp development. We found that ART reduces TCF1/TCF7 nuclear translocation by binding the Ras-related nuclear protein (RAN), suggesting that ART inhibits TCF/LEF transcriptional factor nuclear translocation by binding to RAN, thereby inhibiting Wnt signaling. Our results provide a novel mechanism through which artesunate inhibits intestinal tumorigenesis.

Abstract
Cutaneous side effects are often observed in patients treated with chemotherapeutic agents, including those treated with epidermal growth factor receptor (EGFR) inhibitors. These side effects are not fatal but often require dose reduction of chemotherapies. The mechanisms of epidermal growth factor receptor inhibition-related dermatologic toxicities are unclear, and prophylactic approaches are not well-established. To explore the mechanisms of the cutaneous side effects induced by epidermal growth factor receptor inhibition, we analyzed the metabolome using human keratinocyte cells. We first demonstrated that afatinib and lapatinib induced apoptosis in HaCaT cells. Using liquid chromatography-mass spectrometry, we detected 676 and 482 metabolites and compounds in the cells and media, respectively. We observed diverse metabolic alterations, including glycolysis, TCA metabolism, and polyamine metabolism, and also found a change in glutathione metabolites after epidermal growth factor receptor inhibition, which led to the accumulation of reactive oxygen species. Supplementation of N-acetyl cysteine partly rescued the afatinib-induced apoptosis, suggesting that reactive oxygen species are involved in the cytotoxicity of skin cells. We observed epidermal growth factor receptor inhibitor-associated comprehensive metabolic changes in human keratinocyte cells, suggesting that oxidative stress evokes cutaneous side effects induced by EGFR inhibition.

Abstract
Colorectal cancer (CRC) is the second leading cause of cancer death worldwide. Therefore, it is important to establish useful methods for preventing CRC. One prevention strategy involves the use of cancer chemopreventive agents, including functional foods. We focused on the well‐known cancer chemopreventive agent curcumin, which is derived from turmeric. However, curcumin has the disadvantage of being poorly soluble in water due to its high hydrophobicity. To overcome this problem, the formation of submicron particles with surface controlled technology has been applied to curcumin to give it remarkably improved water solubility, and this derived compound is named Theracurmin. To date, the preventive effects of Theracurmin on hereditary intestinal carcinogenesis have not been elucidated. Thus, we used Apc‐mutant mice, a model of familial adenomatous polyposis, to evaluate the effects of Theracurmin. First, we showed that treatment with 10‐20 µM Theracurmin for 24 hours reduced nuclear factor‐κB (NF‐κB) transcriptional activity in human colon cancer DLD‐1 and HCT116 cells. However, treatment with curcumin mixed in water did not change the NF‐κB promoter transcriptional activity. As NF‐κB is a regulator of inflammation‐related factors, we next investigated the downstream targets of NF‐κB: monocyte chemoattractant protein‐1 (MCP‐1) and interleukin (IL)‐6. We found that treatment with 500 ppm Theracurmin for 8 weeks inhibited intestinal polyp development and suppressed MCP‐1 and IL‐6 mRNA expression levels in the parts of the intestine with polyps. This report provides a proof of concept for the ongoing Theracurmin human trial (J‐CAP‐C study).

Abstract
Colorectal cancer is the fourth leading cause of cancer death worldwide, and it is important to establish effective methods for preventing colorectal cancer. One effective prevention strategy could be the use of antioxidants. However, the role of the direct antioxidative function of antioxidants against carcinogenesis has not been clarified. Thus, we aimed to determine whether the direct removal of reactive oxygen species by a hydroxyl radical scavenger, NZ-419, could inhibit colorectal carcinogenesis. NZ-419 is a creatinine metabolite that has been shown to be safe and to inhibit the progression of chronic kidney disease in rats, and it is now under clinical development. In the present study, we demonstrated that NZ-419 eliminated reactive oxygen species production in HCT116 cells after H2O2 stimulation and suppressed H2O2-induced Nrf2 promoter transcriptional activity. The administration of 500 ppm NZ-419 to Apc-mutant Min mice for 8 weeks resulted in a decrease in the number of polyps in the middle segment of the small intestine to 62.4% of the value in the untreated control (p < 0.05 vs. control group). As expected, NZ-419 treatment affected the levels of reactive carbonyl species, which are oxidative stress markers in the serum of Min mice. Suppression of the mRNA levels of the proliferation-associated factor c-Myc was observed in intestinal polyps of Min mice after NZ-419 treatment, with a weak suppression of epithelial cell proliferation assessed by proliferation cell nuclear antigen (PCNA) staining in the intestinal polyps. This study demonstrated that NZ-419 suppress the development of intestinal polyps in Min mice, suggesting the utility of radical scavenger/antioxidants as a cancer chemopreventive agent.

Abstract
It has been reported that activation of NF-E2 p45-related factor-2 (NRF2), a transcription factor, induces a variety of antioxidant enzymes, and plays an important role in preventing carcinogenesis. AHCC is a standardized extract of cultured Lentinula edodes mycelia and it has been demonstrated to improve cancer. However, the effects of AHCC on NRF2 have not been examined, and the effects on intestinal adenoma development are not yet fully understood. We first investigated the effects of AHCC (1–5 mg/ml) on NRF2 activity in human colon cancer cell lines by a luciferase reporter gene assay, and found NRF2 transcriptional activities were increased ~12.6-fold. In addition, AHCC dose-dependently increased HO-1 and NQO-1 mRNA levels, and decreased interleukine-6 mRNA levels. Next, we administered 1,000 ppm AHCC for 8 weeks in the diet of Apc mutant Min mice, and found that AHCC significantly reduced the total number of intestinal polyps to 57.7% and to 67.6% of the control value in male and female Min mice, respectively, with suppression of interleukine-6 in the polyp part. These data suggest that AHCC possesses an ability to suppress cellular oxidative stress through activation of NRF2, thereby lowering intestinal polyp development in Min mice.

Abstract
Fermented dairy products comprise many functional components. Our previous study using fermented milk showed that the γ-aminobutyric acid (GABA)-producing Lactococcus lactis 01-7 strain can produce unique metabolites such as antihypertensive peptides, whereas this study was designed to find the unique metabolites in GABA-rich cheese using the 01-7 strain. Metabolites between cheese ripening with the non-GABA-producing L. lactis 01-1 strain (control) and GABA-rich cheese ripening with a mixture of 01-1 and 01-7 strains were compared. GABA and ornithine were detected in GABA-rich cheese using an amino acid analyzer and citrate was detected in the control cheese using HPLC. Metabolome analysis using LC-MS showed that peptides with unknown function and those with antihypertensive activity were higher in the GABA-rich cheese than in the control cheese. Further analysis of the amount of the YLGY derivatives showed that the amount of YL in the GABA-rich cheese was lower than that in the control. PRACTICAL APPLICATIONS: Clarification of metabolites in cheese contributes to the improvement of cheese ripening, thereby providing consumers with unique cheese with good nutritional and functional characteristics. The use of the 01-7 strain as a cheese starter might provide a functional cheese with antihypertensive-, antioxidative-, and anxiolytic-like activities.

Abstract
In conventional research methods for cancer prevention, cell proliferation and apoptosis have been intensively targeted rather than the protection of normal or benign tumor cells from malignant transformation. In this study, we aimed to identify candidate colon cancer chemopreventive drugs based on the transcriptional activities of TCF/LEF, NF-κB and NRF2, that play important roles in the process of malignant transformation. We screened a “validated library” consisting of 1280 approved drugs to identify hit compounds that decreased TCF/LEF and NF-κB transcriptional activity and increased NRF2 transcriptional activity. Based on the evaluation of these 3 transcriptional activities, 8 compounds were identified as candidate chemopreventive drugs for colorectal cancer. One of those, itraconazole, is a clinically used anti-fungal drug and was examined in the Min mouse model of familial adenomatous polyposis. Treatment with itraconazole significantly suppressed intestinal polyp formation and the effects of itraconazole on transcriptional activities may be exerted partly through inhibition of intracellular cholesterol trafficking. This screen represents one of the first attempts to identify chemopreventive agents using integrated criteria consisting of the inhibition of TCF/LEF, NF-κB and induction of NRF2 transcriptional activity.

Abstract
Background Evidence from epidemiological and experimental studies has shown that the etiology of colorectal cancer (CRC) is related to lifestyle, mainly diet. At the same time, there are many foods and beverages that have been shown to provide protection against CRC. We turned our attention to a traditional Japanese food, brown algae, that contains carotenoids and various functional polyphenols, especially fucoxanthin (FX) and fucoxanthinol (FxOH). Results Both FX and FxOH treatments induced apoptosis in a dose-dependent and time-dependent manner as detected by annexin V / propidium iodide and the presence of a subG1 population in human colon cancer HCT116 cells. This apoptotic effect of FxOH was stronger than that of FX. We also found that nuclear factor-kappa B (NF-κB) transcriptional activity was significantly increased by treatment with ≥5 μM FxOH. Thus, we cotreated the cells with FxOH plus NF-κB inhibitor, and the results demonstrated that this cotreatment strongly enhanced the induction of apoptosis compared with the effects of FxOH or NF-κB inhibitor treatment alone and resulted in X-linked inhibitor of apoptosis (IAP) downregulation. Conclusions This study suggested that FxOH is a more potent apoptosis-inducing agent than FX and that its induction of apoptosis is enhanced by inhibiting NF-κB transcriptional activity via suppression of IAP family genes.

Abstract
Caloric restriction (CR) delays the onset of many age-related pathophysiological changes and extends lifespan. White adipose tissue (WAT) is not only a major tissue for energy storage, but also an endocrine tissue that secretes various adipokines. Recent reports have demonstrated that alterations in the characteristics of WAT can impact whole-body metabolism and lifespan. Hence, we hypothesized that functional alterations in WAT may play important roles in the beneficial effects of CR. Previously, using microarray analysis of WAT from CR rats, we found that CR enhances fatty acid (FA) biosynthesis, and identified sterol regulatory element-binding protein 1c (SREBP-1c), a master regulator of FA synthesis, as a mediator of CR. These findings were validated by showing that CR failed to upregulate factors involved in FA biosynthesis and to extend longevity in SREBP-1c knockout mice. Furthermore, we revealed that SREBP-1c is implicated in CR-associated mitochondrial activation through the upregulation of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), a master regulator of mitochondrial biogenesis. Notably, these CR-associated phenotypes were observed only in WAT. We conclude that CR induces SREBP-1c-dependent metabolic remodeling, including the enhancement of FA biosynthesis and mitochondrial activation, via PGC-1α in WAT, resulting in beneficial effects.

Abstract
Sirtuin‐3 (SIRT3) regulates mitochondrial quality and is involved in the anti‐ageing and pro‐longevity actions of caloric restriction (CR). Here, we show that CR upregulates the mature form of SIRT3 and mitochondrial intermediate peptidase (MIPEP), a mitochondrial signal peptidase (MtSPase), in white adipose tissue. We also demonstrate that upregulation of mature SIRT3 is dependent on MIPEP in 3T3‐L1 cells, suggesting that MIPEP may contribute to the maintenance of mitochondrial quality during CRvia activation of SIRT3. This novel mechanism of SIRT3 activation through MIPEP facilitates the elucidation of additional molecular pathways of CR.

Abstract
BACKGROUND Over the past few decades, beef producers in Japan have improved marbling in their beef products. It was recently reported that marbling is not well correlated with palatability as rated by Japanese consumers. This study sought to identify the consumer segments in Japan that prefer sensory characteristics of beef other than high marbling. RESULTS Three Wagyu beef, one Holstein beef and two lean imported beef longissimus samples were subjected to a descriptive sensory test, physicochemical analysis and a consumer (n = 307) preference test. According to consumer classification and external preference mapping, four consumer segments were identified as 'gradual high-fat likers', 'moderate-fat and distinctive taste likers', 'Wagyu likers' and 'distinctive texture likers'. Although the major trend of Japanese consumers' beef preference was 'marbling liking', 16.9% of the consumers preferred beef samples that had moderate marbling and distinctive taste. The consumers' attitudes expressed in a questionnaire survey were in good agreement with the preference for marbling among the 'moderate-fat and distinctive taste likers'. CONCLUSION These results indicate that moderately marbled beef is a potent category in the Japanese beef market. © 2017 Society of Chemical Industry.

Abstract
We recently reported that wearing unstable rocker shoes (Masai Barefoot Technology: MBT) may enhance recovery from marathon race-induced fatigue. However, this earlier study only utilized a questionnaire. In this study, we evaluated MBT utilizing objective physiological measures of recovery from marathon-induced muscle damages. Twenty-five university student novice runners were divided into two groups. After running a full marathon, one group wore MBT shoes (MBT group), and the control group (CON) wore ordinary shoes daily for 1 week following the race. We measured maximal isometric joint torque, muscle hardness (real time tissue elastography of the strain ratio) in the lower limb muscles before, immediately after, and 1, 3, and 8 days following the marathon. We calculated the magnitude of recovery by observing the difference in each value between the first measurement and the latter measurements. Results showed that isometric torques in knee flexion recovered at the first day after the race in the MBT group while it did not recover even at the eighth day in the CON group. Muscle hardness in the gastrocnemius and vastus lateralis showed enhanced recovery in the MBT group in comparison with the CON group. Also for muscle hardness in the tibialis anterior and biceps femoris, the timing of recovery was delayed in the CON group. In conclusion, wearing MBT shoes enhanced recovery in lower leg and thigh muscles from muscle damage induced by marathon running.

Abstract
Caloric restriction (CR) can delay onset of several age‐related pathophysiologies and extend lifespan in various species, including rodents. CR also induces metabolic remodeling involved in activation of lipid metabolism, enhancement of mitochondrial biogenesis, and reduction of oxidative stress in white adipose tissue (WAT). In studies using genetically modified mice with extended lifespans, WAT characteristics influenced mammalian lifespans. However, molecular mechanisms underlying CR‐associated metabolic remodeling of WAT remain unclear. Sterol regulatory element‐binding protein‐1c (Srebp‐1c), a master transcription factor of fatty acid (FA) biosynthesis, is responsible for the pathogenesis of fatty liver (steatosis). Our study showed that, under CR conditions, Srebp‐1c enhanced mitochondrial biogenesis via increased expression of peroxisome proliferator‐activated receptor gamma coactivator‐1α (Pgc‐1α) and upregulated expression of proteins involved in FA biosynthesis within WAT. However, via Srebp‐1c, most of these CR‐associated metabolic alterations were not observed in other tissues, including the liver. Moreover, our data indicated that Srebp‐1c may be an important factor both for CR‐associated suppression of oxidative stress, through increased synthesis of glutathione in WAT, and for the prolongevity action of CR. Our results strongly suggested that Srebp‐1c, the primary FA biosynthesis‐promoting transcriptional factor implicated in fatty liver disease, is also the food shortage‐responsive factor in WAT. This indicated that Srebp‐1c is a key regulator of metabolic remodeling leading to the beneficial effects of CR.

Abstract
Bortezomib (BTZ), a proteasome inhibitor, is widely used in the treatment of multiple myeloma (MM), but a fraction of patients respond poorly to this agent. To identify factors predicting the duration of progression-free survival (PFS) of MM patients on BTZ treatment, the expression of proteasome and endoplasmic reticulum (ER) stress-related genes was quantified in primary samples from patients receiving a combination of BTZ and dexamethasone (BD). Fifty-six MM patients were stratified into a group with PFS<6 months (n=33) and a second group with PFS⩾6 months (n=23). Of the 15 genes analyzed, the expression of activating transcription factor 3 (ATF3) and ATF4 was significantly lower in patients with shorter PFS (P=0.0157 and P=0.0085, respectively). Chromatin immunoprecipitation analysis showed that these ATFs bind each other and transactivate genes encoding the pro-apoptotic transcription factors, CHOP and Noxa, which promote ER stress-associated apoptosis. When either ATF3 or ATF4 expression was silenced, MM cells partially lost sensitivity to BTZ treatment. This was accompanied by lower levels of Noxa, CHOP and DR5. Thus low basal expression of ATF3 and ATF4 may attenuate BTZ-induced apoptosis. Hence, ATF3 and ATF4 could potentially be used as biomarkers to predict efficacy of BD therapy in patients with MM.

The beneficial actions of caloric restriction (CR) could be mediated in part by metabolic remodeling of white adipose tissue (WAT). Recently, we suggested that CR for 6 months increased the expressions of proteins involved in de novo fatty acid (FA) biosynthesis in WAT of 9-month-old rats. Herein, we compared the CR-induced chronological alterations of the expression of mRNAs and/or proteins involved in FA biosynthesis in the WAT and liver of rats subjected to CR starting from 3 months of age and their age-matched controls fed ad libitum. The findings suggested that CR was more effective on FA biosynthesis in WAT than in liver. In WAT, CR markedly increased the expressions of mRNAs and/or proteins involved in FA biosynthesis, including sterol regulatory element-binding protein 1c (SREBP1c), a master transcriptional regulator of FA biosynthesis, throughout the experimental period. Interestingly, the CR-enhanced upregulation was temporally attenuated at 5 months of age. CR markedly increased the nuclear phosphorylated form of Akt only at 3.5 months of age. In contrast, CR significantly reduced the expression of leptin at 9 months of age. The CR-induced upregulation was not observed in obese fa/fa Zucker rats homozygous for nonfunctional leptin receptor. Collectively, these data indicate that the V-shaped chronological alterations in WAT are regulated via SREBP1c, which is probably activated by CR duration-dependent modulation of both insulin and leptin signaling.

Abstract
Texture and ‘tenderness’ in particular, is an important sensory characteristic for consumers’ satisfaction of beef. Objective and detailed sensory measurements of beef texture have been needed for the evaluation and management of beef quality. This study aimed to apply the sensory scales defined in ISO11036:1994 to evaluate the texture of beef. Longissimus and Semitendinosus muscles of three Holstein steers cooked to end-point temperatures of 60°C and 72°C were subjected to sensory analyses by a sensory panel with expertise regarding the ISO11036 scales. For the sensory analysis, standard scales of ‘chewiness’ (9-points) and ‘hardness’ (7-points) were presented to the sensory panel with reference materials defined in ISO11036. As a result, both ‘chewiness’ and ‘hardness’ assessed according to the ISO11036 scales increased by increasing the cooking end-point temperature, and were different between Longissimus and Semitendinosus muscles. The sensory results were in good agreement with instrumental texture measurements. However, both texture ratings in this study were in a narrower range than the full ISO scales. For beef texture, ISO11036 scales for ‘chewiness’ and ‘hardness’ are useful for basic studies, but some alterations are needed for practical evaluation of muscle foods.

Abstract
The role of the growth hormone (GH)-insulin-like growth factor (IGF)-1 axis in the lifelong caloric restriction (CR)-associated remodeling of white adipose tissue (WAT), adipocyte size, and gene expression profiles was explored in this study. We analyzed the WAT morphology of 6-7-month-old wild-type Wistar rats fed ad libitum (WdAL) or subjected to CR (WdCR), and of heterozygous transgenic dwarf rats bearing an anti-sense GH transgene fed ad libitum (TgAL) or subjected to CR (TgCR). Although less effective in TgAL, the adipocyte size was significantly reduced in WdCR compared with WdAL. This CR effect was blunted in Tg rats. We also used high-density oligonucleotide microarrays to examine the gene expression profile of WAT of WdAL, WdCR, and TgAL rats. The gene expression profile of WdCR, but not TgAL, differed greatly from that of WdAL. The gene clusters with the largest changes induced by CR but not by Tg were genes involved in lipid biosynthesis and inflammation, particularly sterol regulatory element binding proteins (SREBPs)-regulated and macrophage-related genes, respectively. Real-time reverse-transcription polymerase chain reaction analysis confirmed that the expression of SREBP-1 and its downstream targets was upregulated, whereas the macrophage-related genes were downregulated in WdCR, but not in TgAL. In addition, CR affected the gene expression profile of Tg rats similarly to wild-type rats. Our findings suggest that CR-associated remodeling of WAT, which involves SREBP-1-mediated transcriptional activation and suppression of macrophage infiltration, is regulated in a GH-IGF-1-independent manner.

Abstract
From the adipose tissues of pork carcasses stored in a refrigerator, Raman spectra were observed in situ by a portable Raman spectrometer. The observed Raman spectra, which were almost completely due to fat, showed clear dependence on the refrigeration time and carcass temperature. This dependence reflected an increase in the crystallinity of the fat and a change in the fraction of the β' polymorph. Evidence of changes in the packing order of the aliphatic chains of acylglycerol molecules was obtained, and the changes lasted for a long time after the temperature reached the lowest point (4.3 °C). Possibilities of using Raman spectrometry as a tool for routine monitoring of the conditions of carcasses as well as for research on the improvement of the mechanical strength of the adipose tissue are discussed.

Abstract
Cytokeratin 19 is a subunit of cytokeratin intermediate filament. CYFRA 21-1 is a new tumor marker using monoclonal antibodies which recognize a fragment of cytokeratin 19. CYFRA 21-1 was measured in cytosol of breast cancer tissues or in sera of patients with breast cancer or benign breast diseases to study the significance of this protein as a tumor marker. The cytosol concentration of CYFRA 21-1 was elevated in cancerous tissue compared to that in adjacent noncancerous tissue, and correlated with the tumor stage or the estrogen receptor status. In the serum, the mean value and positive rate for CYFRA 21-1 (assuming 2.2 ng/ml as the cut-off value) were 0.61 ng/ml (0%) in benign breast diseases, 0.98 ng/ml (6.7%) in stage I/II primary breast cancer, 75.67 ng/ml (60.0%) in stage III/IV primary breast cancer, 45.28 ng/ml (60.0%) in recurrent breast cancer, and 0.64 ng/ml (2.6%) in those with no evidence of recurrence. From the above, we concluded that CYFRA 21-1 could be a tumor marker with high specificity in breast cancer.

Abstract
The hematogenous metastasis of cancer consists of a multistep process. It is surmised that a number of interactions between cancer and endothelial cells occur, with cell adhesion molecules playing certain roles in this process. The authors conducted an investigation on the interaction between human cancer cells and cultured murine endothelial cells (F-2 cells) in vitro, and on its relationship with the metastatic activity of cancer cells in vivo. A correlation was found between the degree of expression of carbohydrate antigens on the cell surface and adhesion of cancer cells to F-2 cells. Five of 13 examined cell lines showed liver metastasis after inoculation to the spleen of nude mice. These cell lines showed not only a strong binding activity to F-2 cells but implantation in F-2 cells in vitro was also observed. These findings suggest that adhesion to, and implantation in endothelial cells are necessary for the induction of distant metastasis. Treatment with antibodies against carbohydrate antigens inhibited the formation of liver metastasis in nude mice. It is possible that strategies to interfere with the function of cell adhesion molecules may be formulated to result in the decreased distant metastasis of cancer.

Abstract
To compare the effects of miglitol [an alpha-glucosidase inhibitor (AGI) absorbed in the intestine] and voglibose (an AGI not absorbed) on plasma glucagon-like peptide-1 (GLP-1) and gastric inhibitory polypeptide (GIP) levels, 26 and 24 Japanese type 2 diabetic patients were randomly assigned to receive miglitol or voglibose, respectively. After 12-week administration of both drugs, during 2-h meal tolerance test, plasma glucose, serum insulin and total GIP were significantly decreased and active GLP-1 was significantly increased. Miglitol group showed a significantly lower total GIP level than voglibose group. Miglitol, but not voglibose, significantly reduced body weight (BW). In all participants, the relative change in BW was positively correlated with that of insulin significantly and of GIP with a weak tendency, but not of GLP-1. In conclusion, both drugs can enhance postprandial GLP-1 responses and reduce GIP responses. The significant BW reduction by miglitol might be attributable to its strong GIP-reducing efficacy.

Abstract
It is considered that high-fat beef is more 'tender' than low-fat beef in Japanese consumers. However, 'tenderness' which has been an important beef characteristic, has not been commonly defined. ISO5492:1992 provides internationally established items for sensory texture analysis with simple definitions, and the items classified under 'chewiness' and 'hardness' as defined in the international standard are characterized as useful texture descriptors for beef. The aim of this study was to investigate the effects of intramuscular fat on beef texture using the ISO5492 texture vocabulary. Longissimus muscles were harvested from Holstein × Japanese black F1 beef steers with different intramuscular fat levels and were subjected to sensory tests by a trained panel using ISO5492:1992 texture terms. Correspondence analysis indicated that the intramuscular fat level was related to both 'chewiness' and 'hardness' and the intensities of these characteristics decreased as intramuscular fat increased. These findings suggest that intramuscular fat improves both 'chewiness' and 'hardness' as defined in ISO5492:1992.

Abstract
BACKGROUND A direct renin inhibitor (DRI) had a benefit in decreasing albuminuria in type 2 diabetic patients having already been treated with angiotensin (Ang) II type 1 receptor blocker (ARB), suggesting that aliskiren may have another effect other than blockade of the traditional renin-angiotensin system (RAS). Recently, prorenin bound to (pro)renin receptor ((P)RR) was found and shown to evoke two pathways; the generation of Ang peptides and the receptor-dependent activation of extracellular signal-related protein kinase (ERK). Because (P)RR is present in the podocytes, a central component of the glomerular filtration barrier, we hypothesized that aliskiren influences the (P)RR-induced two pathways in human podocytes. METHODS Human podocytes were treated with 2 nmol/l prorenin in the presence and absence of an angiotensin-converting enzyme inhibitor (ACEi) imidaprilat, an ARB candesartan, a DRI aliskiren, or the siRNA knocking down the (P)RR mRNA and the intracellular AngII levels and the phosphorylation of ERK were determined. RESULTS The expression of (P)RR mRNA of human podocytes was unaffected by the treatment with RAS inhibitors, but decreased by 69% with the siRNA treatment. The basal levels of intracellular AngII and the prorenin-induced increase in intracellular AngII were significantly reduced by aliskiren and siRNA treatment, compared with imidaprilat and candesartan. The prorenin-induced ERK activation was reduced to control level by the siRNA treatment, but it was unaffected by imidaprilat, candesartan, or aliskiren. CONCLUSIONS Aliskiren is the most potent inhibitor of intracellular AngII levels of human podocytes among RAS inhibitors, although it is incapable of inhibiting the (P)RR-dependent ERK phosphorylation.

Abstract
Previous studies of diabetic patients indicate that increased urinary excretion of certain plasma proteins (molecular radii <55 A), such as IgG, transferrin, and ceruloplasmin, precede the development of microalbuminuria. Moreover, increases in these urinary proteins predict future development of microalbuminuria. To clarify whether blood pressure changes influence urinary excretion of these proteins, we examined relationships between diurnal blood pressure changes measured by ambulatory blood pressure monitoring and urinary excretion of IgG, transferrin, ceruloplasmin, alpha2-macroglobulin (88 A) and albumin (36 A) measured separately during the day and night in 20 healthy controls and 26 normotensive, normoalbuminuric diabetic patients. Diurnal change in systolic blood pressure was not correlated to urinary excretion of either albumin or alpha2-macroglobulin in either diabetic patients or controls. However, statistically significant correlations between diurnal changes in systolic blood pressure and those of urinary excretion of IgG, transferrin and ceruloplasmin were found in diabetic patients but not in controls. The present findings suggest that urinary excretion of IgG, transferrin, and ceruloplasmin are more easily affected than albuminuria by systemic blood pressure changes in normoalbuminuric diabetic patients. This is supported by our previous finding that urinary excretion of IgG, transferrin and ceruloplasmin increased while albuminuria did not following enhanced glomerular filtration rate after acute protein loading, which causes increased glomerular capillary pressure due to afferent arterioles dilation, mimicking diabetic intra-renal hemodynamics. Taken together, these findings suggest that urinary excretion of IgG, transferrin, and ceruloplasmin may be more sensitive indicators of glomerular capillary pressure change than albuminuria in normoalbuminuric diabetic patients.

Abstract
AIMS The aim of this study was to obtain new Lactococcus lactis strains from nondairy materials for use as milk fermentation starters. The genetic and phenotypic traits of the obtained strains were characterized and compared with those of L. lactis strains derived from milk. It was confirmed that the plant-derived bacteria could be used as milk fermentation starters. METHODS AND RESULTS About 2600 lactic acid bacteria were subjected to screening for L. lactis with species-specific PCR. Specific DNA amplification was observed in 106 isolates. Forty-one strains were selected, including 30 strains of milk-derived and 11 of plant-derived, and their phenotypic traits and genetic profiles were determined. The plant-derived strains showed tolerance for high salt concentration and high pH value, and fermented many more kinds of carbohydrates than the milk-derived strains. There were no remarkable differences in the profiles of enzymes, such as lipases, peptidases and phosphatases. Isolates were investigated by cluster analysis based on randomly amplified polymorphic DNA profiles. There were no significant differences between isolates from milk and those from plant. The L. lactis subsp. cremoris strains were clustered into two distinct groups, one composed of the strains having the typical cremoris phenotype and the other composed of strains having a phenotype similar to subsp. lactis. Fermented milk manufactured using the plant-derived strains were not inferior in flavour to that manufactured using the milk-derived strains. CONCLUSIONS Plant-derived L. lactis strains are genetically close to milk-derived strains but have various additional capabilities, such as the ability to ferment many additional kinds of carbohydrates and greater stress-tolerance compared with the milk-derived strains. SIGNIFICANCE AND IMPACT OF THE STUDY The lactic acid bacteria obtained from plants in this study may be applicable for use in the dairy product industry.
