Abstract
Regulatory T cells (Tregs) play a central role in modulating adaptive immune responses in humans and mice. The precise biological role of non-canonical nuclear factor 'κ-light-chain-enhancer' of activated B cells (NFKB) signaling in human Tregs has yet to be fully elucidated. To gain insight into this process, a Treg-like cell line (MT-2) was genetically modified using CRISPR/Cas9. Interestingly, NFKB2 knockout MT-2 cells exhibited downregulation of FOXP3, while NFKB1 knockout did not. Additionally, mRNA expression of FOXP3-dependent molecules was significantly reduced in NFKB2 knockout MT-2 cells. To better understand the functional role of the NFKB signaling, the NFKB1/NFKB2 loci of human primary Tregs were genetically edited using CRISPR/Cas9. Similar to MT-2 cells, NFKB2 knockout human Tregs displayed significantly reduced FOXP3 expression. Furthermore, NFKB2 knockout human Tregs showed downregulation of FOXP3-dependent molecules and a diminished suppressive function compared to wild-type and NFKB1 knockout Tregs. These findings indicate that non-canonical NFKB signaling maintains a Treg-like phenotype and suppressive function in human Tregs through the FOXP3-dependent regulatory T cell program.

Abstract
Background/Aim Elevated blood fibronectin (FN) levels have been observed in various cancers; however, their significance is controversial. We measured sialyl-fibronectin (S-FN), a type of FN secreted by tumor cells in the blood, and investigated whether blood S-FN secretion is associated with cancer malignancy and recurrent metastases. Materials and Methods We constructed an enzyme-linked immunosorbent assay (ELISA) system that recognizes S-FN as an antigen and measured the amount of S-FN secreted into the blood of 89 patients with breast tumors. The relationship between S-FN secretion and prognostic predictors was analyzed. Immunostaining was performed to identify the site of S-FN secretion in the breast tissue. Results Among the 82 patients, 21 (25.6%, 21/82) and 61 (74.4%, 61/82) were blood S-FN-positive and S-FN-negative, respectively. Regarding prognostic predictors, blood S-FN-positive and S-FN-negative patients showed significant difference in locoregional recurrence (p=0.026), remote metastases (p=0.049), and histological margins (p=0.001). Locoregional recurrence was associated with positive histological margins in S-FN-positive patients. However, remote metastases were associated with N-factor and histological classification (HC) in S-FN-negative patients. Furthermore, S-FN particles were detected in the cytoplasm of breast cancer cells through immunostaining. After the onset of recurrent metastases, two S-FN-positive and six S-FN-negative patients received anticancer drug treatment; however, further progression was observed in five S-FN-negative patients. Conclusion S-FN-positive patients are less likely to develop distant metastases, have a better prognosis, and may be less resistant to therapeutic agents than S-FN-negative patients, which contain many epithelial-mesenchymal transition cells.

Abstract
Type 1 ryanodine receptor (RYR1) is a Ca2+ release channel in the sarcoplasmic reticulum (SR) of the skeletal muscle and plays a critical role in excitation-contraction coupling. Mutations in RYR1 cause severe muscle diseases, such as malignant hyperthermia, a disorder of Ca2+-induced Ca2+ release (CICR) through RYR1 from the SR. We recently reported that volatile anesthetics induce malignant hyperthermia (MH)-like episodes through enhanced CICR in heterozygous R2509C-RYR1 mice. However, the characterization of Ca2+ dynamics has yet to be investigated in skeletal muscle cells from homozygous mice because these animals die in utero. In the present study, we generated primary cultured skeletal myocytes from R2509C-RYR1 mice. No differences in cellular morphology were detected between wild type (WT) and mutant myocytes. Spontaneous Ca2+ transients and cellular contractions occurred in WT and heterozygous myocytes, but not in homozygous myocytes. Electron microscopic observation revealed that the sarcomere length was shortened to ∼1.7 µm in homozygous myocytes, as compared to ∼2.2 and ∼2.3 µm in WT and heterozygous myocytes, respectively. Consistently, the resting intracellular Ca2+ concentration was higher in homozygous myocytes than in WT or heterozygous myocytes, which may be coupled with a reduced Ca2+ concentration in the SR. Finally, using infrared laser-based microheating, we found that heterozygous myocytes showed larger heat-induced Ca2+ transients than WT myocytes. Our findings suggest that the R2509C mutation in RYR1 causes dysfunctional Ca2+ dynamics in a mutant-gene dose-dependent manner in the skeletal muscles, in turn provoking MH-like episodes and embryonic lethality in heterozygous and homozygous mice, respectively.

Abstract
Abstract
Breast cancer is frequently characterized by calcifications in mammography. Although breast calcifications were previously thought to be produced passively as the final stage of cell regression, recent studies have shown active production. In another context, vascular smooth muscle cells have been found to produce vascular calcifications by acquiring osteoblast-like characteristics. The same mechanism has been suggested to account for breast calcifications. A report showed that breast calcifications are clearly generated by the mouse breast cancer cell line 4T1 through osteoblast-like characteristics. However, the details underlying such a mechanism of mammary calcification is unknown. Understanding this mechanism will improve diagnostic accuracy for breast cancer. We induced calcifications using osteogenic cocktail on the human breast cancer cell line MDA-MB-231. Our hypothesis was that breast cancer calcifications are generated in a process similar to that of osteoblast differentiation. By a comprehensive analysis of transcription compared with osteoblastic cell line MC3T3-E1 in a microarray, we showed that placental alkaline phosphatase (PLAP) is involved in producing calcifications through PI3K-Akt signaling pathways. Herein, we demonstrated that calcifications occur and that alkaline phosphatase enzyme activity increases in MDA-MB-231 cells cultured using an osteogenic cocktail-containing medium. Microarray transcript analysis showed that the PI3K-Akt signaling pathway was significantly involved, with recruitment of placental alkaline phosphatase. Calcifications and alkaline phosphatase enzyme activity were suppressed by silencing placental alkaline phosphatase using a small interfering RNA. Inhibition of the PI3K-Akt signaling pathway suppressed phospho-c-Jun and placental alkaline phosphatase and resulted in absence of calcifications. These findings reveal that breast cancer cells acquire alkaline phosphatase enzyme activity via placental alkaline phosphatase expression and suggest that breast calcification formation is closely associated with the PI3K-Akt signaling pathway. Our results suggest that PLAP produces ALP enzyme activity required for calcification in MDA-MB-231 cells. PLAP is clinically expressed in some breast cancers. A report showed that dexamethasone induces PLAP enzyme activity and mRNA in the human breast cancer BC-M1 cell line. Therefore, dexamethasone in osteogenic cocktail may be associated with PLAP expression in the MDA-MB-231 cells. On the other hand, c-Jun binds to the promoter region of ALPP in MDA-MB-231, and we showed that c-Jun phosphorylation appears in MDA-MB-231 cells cultured using osteogenic cocktail. We suggest that PLAP transcript would be activated when phospho-c-Jun enters the nucleus and binds to the promoter region of PLAP. Our proposed mechanism in breast calcifications is that osteogenic cocktail induces c-Jun phosphorylation via PI3K-Akt signaling pathway and that PLAP transcription would be activated when phospho-c-Jun enters the nucleus and binds to the promoter region of PLAP. Future research might assess whether increased PLAP levels are the main driver of intracellular calcifications in breast cancer, as well as whether the PI3K-Akt signaling pathway has a similar effect in vivo that we demonstrated to cause calcifications in vitro.

Abstract
BACKGROUND Compared to two-dimensional cultures, three-dimensional (3D) cultures have many advantages in cancer studies. Nevertheless, their implementation is unsatisfactory. This study aimed to develop an anchorage-dependent 3D culture model for colorectal cancer research. MATERIALS AND METHODS Human HCT116, DLD-1 and SW620 colorectal cell lines were cultured in a gelatin sponge, and its applicability for morphological examination was studied. RESULTS The resulting specimens were suitable for scanning electron microscopy, transmission electron microscopy, and immunohistochemical examination. HCT116 formed smaller structures and migrated through the pores of the sponge. DLD-1 formed larger structures with tight cell-to-cell adhesion. SW620 also formed large structures but small clustered cells tended to attach to the anchorage more favorably. Immunohistochemical staining demonstrated phosphorylated yes-associated protein (YAP) localized near the attachment site in HCT116 cells. CONCLUSION Because the gelatin sponge provided suitable anchorage and the cultured cells formed distinguishable 3D structures, this method may be useful for further colorectal cancer research.

Abstract
Background The recent trend of pharmaceutical companies commercializing new objects as new drugs based on the findings of academic medical researchers, commonly categorizing them as "academic drug discovery" is increasingly gaining popularity in the pharmaceutical industry. Studies state that academic researchers based in universities have lower motivation to apply for patents. However, none of the studies evaluated the existence and extent of the "motivation for patent" in academic researchers, being lower than that of pharmaceutical companies. This study assesses two hypotheses; H1: academic medical researchers are less likely to believe that the patent system is necessary for pharmaceuticals, and thus have diminished interest in the commercialization of their research findings when compared to those in the pharmaceutical industry, H2: apprehension of the raison d'être of the patent system affects positive impressions on patents among academic medical researchers. Methods From February to March 2020, an anonymous survey was conducted among academic medical researchers, pharmaceutical industry professionals, and IP researchers based in Japan. Overall response rate was 27.4% (192/700). We conducted an analysis of variance for H1 and used the PLS-SEM model for H2 in order to verify the hypotheses. Results The results confirmed that the mean calculated from the responses of the academic medical researchers was significantly lower than the mean of pharmaceutical company personnel when responses to patenting an emerging technology or drug for the advancement of medicine were analyzed. In addition, we found that a causal relationship between academic medical researchers' understanding of patents and their positive impressions on patents, depending on the degree to which they consider that the patent system is to encourage and promote new inventions. Conclusion We conclude that a contrasting perception of patents not only exists between academic medical researchers and pharmaceutical company personnel but also it is caused by their apprehension of patents. More efforts to promote the raison d'être of the patent system among academic medical researchers will enable them to view pharmaceutical patents in a more positive light. Through this study, the pertinence to promote academic drug discoveries has been uncovered.

Abstract
Background Banana juice is becoming a popular beverage in Japan and the number of soft-drink stands or shops that take great care and pride in the quality of their products has been increasing. This study aims to measure the scent of banana juice from different brands using the electronic (e-) nose FF-2A in order to identify the characteristics, time-related changes, and the differences among them. Methods We standardized the scent value of banana juice measured using FF-2A and determined the absolute value in three different shops. We compared the similarities in samples from each shop with axis data created using standardized measurement. With FF-2A we identified the scent common to all banana juice samples from the composite scent and numerically showed the similarity to the reference gas. Results The juices from each shop had their own characteristics and we were able to identify the difference between some of these. The response of FF-2A varied according to the increase/decrease in the number of characteristic molecules measured by GC-MS such as overtime fluctuations in the gas. These data were shown along with the differences between the various banana juices. Conclusions FF-2A was able to identify the scent of banana juice at each banana shop as well as time-related changes. By combining GC-MS, we were able to evaluate scent components that changed over time. The results using the electronic nose may prove useful for objective evaluation and comparison of scent with other types of juices.

Abstract
BACKGROUND/AIM Nicotinamide phosphoribosyl-transferase (NAMPT) is a rate-limiting enzyme in the pathway synthesizing nicotinamide adenine dinucleotide (NAD (+)) from nicotinamide (NAM). Glioma tissues exhibit up-regulated NAMPT expression associated with a poor prognosis of patients. To determine if NAMPT can be a molecular therapeutic target, we investigated the effects of short hairpin RNA (shRNA)-mediated NAMPT down-regulation. MATERIALS AND METHODS We designed shRNA to NAMPT and transfected to T98G cells. The characteristics of these cells were analyzed. RESULTS The NAMPT shRNA-transfected cells exhibited delayed cell growth. However, there was no difference in the increase of sensitivity to temozolomide (TMZ) or X-ray irradiation between the NAMPT and scramble shRNA-transfected cells. The expression of NAMPT in the NAMPT shRNA-transfected cells increased with cell passage. Additionally, the shRNA-mediated transfection was associated with enhanced expression of quinolinic acid phosphoribo-syltransferase (QPRT). CONCLUSION shRNA-mediated NAMPT down-regulation may not decrease the NADt to a sufficient level to increase TMZ/radiation sensitivity.

Abstract
BACKGROUND/AIM The expression of corticotropin-releasing hormone (CRH)-related peptides involved in stress response in colorectal cancer has been reported. We examined the involvement of CRH-related peptides in cellular stress caused by anticancer drugs in colorectal cancer. MATERIALS AND METHODS Changes in the expression levels of CRH-related peptides and their receptors in HCT116, DLD-1, and SW480 cell lines after fluorouracil (5-FU) loading were evaluated. Effects of the receptor antagonist against DNA synthesis disorder caused by 5-FU and SN-38 were evaluated using the 3H-labeled deoxyribonucleoside incorporation assay. RESULTS No changes in the mRNA expression levels of CRH-related peptides (UCN and UCN2) -and their receptors (CRHR1 and CRHR2) were observed. Addition of antagonists to cells with DNA synthesis disorder caused by 5-FU and SN-38 showed no differences in the incorporation of 3H-labeled deoxyribonucleoside. CONCLUSION CRH-related peptides showed no effect on the stress response to anticancer drugs nor on DNA synthesis disorder in colorectal cancer.

Abstract
Chemotherapy resistance (congenital or acquired) is one of the principal challenges for the treatment of pancreatic carcinoma. Recent evidence has demonstrated that epithelial to mesenchymal transition (EMT) is associated with chemoresistance in pancreatic carcinoma cells. However, the molecular mechanism underlying the development of chemoresistance remains unknown, and limited therapeutic options are available. Therefore, to anticipate individual chemosensitivity or acquired chemoresistance for patients with pancreatic carcinoma, predictive biomarkers are urgently required. Extensive evidence suggests that microRNAs (miRNAs) serve a crucial role in regulating EMT. The aim of this study was to examine the potential role of miRNA (miR)‑200b and miR‑301 in predicting the chemo‑responses to treatment for pancreatic carcinoma. The present results demonstrate that miR‑200b expression predicted chemo‑sensitivity and may have potential as a biomarker. In six different pancreatic carcinoma cell lines (Capan‑1, Capan‑2, Panc‑1, MIAPaCa‑2, BxPC‑3 and PL45 cells), the expression of miR‑200b correlated positively with chemosensitivity. Moreover, the enhanced expression of miR‑200b increased chemosensitivity and induced mesenchymal to epithelial transition. Conversely, miR‑301 modulated gemcitabine resistance and induced EMT through the downregulation of cadherin 1 expression. In addition, gemcitabine‑resistant cells (Capan‑2 and Panc‑1) exhibited upregulated miR‑301 expression and downregulated gemcitabine‑induced apoptosis. In summary, these two miRNAs may serve roles as biomarkers in pancreatic carcinoma, miR‑200b expression may predict chemosensitivity, and elevated miR‑301 expression may have potential applications in the prediction of acquired gemcitabine resistance.

Abstract
BACKGROUND Anticoagulation therapy is often used to prevent stroke in patients with thyroid cancer. However, the effects of heparin and protamine on thyroid cancer are unknown; therefore, we examined the response of thyroid cancer cell lines to heparin and protamine. MATERIALS AND METHODS Cytotoxic assay for heparin-protamine treatment was examined on SW1736, 8505c and 8305c cell lines. RESULTS The half-maximal inhibitory concentration of the heparin-protamine treatment was 82.1 μg/ml for the SW1736 cell line, 10.4 μg/ml for 8505c, and 17.8 μg/ml for 8305c. Each cell line expresses fibronectin, with SW1736 expressing mutant fibronectin; thus, it is possible that mutant fibronectin may prevent the antitumor effect in SW1736 cells. CONCLUSION The SW1736 cell line did not show any antitumor effect after heparin-protamine treatment. Further research is needed on why heparin-protamine treatment does not exert an antitumor effect on SW1736 cells, and the results of this research could mean that the heparin-protamine treatment might be used to provide antitumor effects in some thyroid cancer cases.

Abstract
Glioblastoma multiforme (GBM) is a treatment-resistant malignancy with poor prognosis. Temozolomide (TMZ) is widely used as a first-line drug for GBM. Although this improves patient prognosis, it does not completely eradicate the tumour. Even after total surgical resection, GBM can exhibit uncontrollable invasiveness at the tumour margins owing to activation of matrix metalloproteinases (MMPs) such as MMP-2 and -9; these degrade collagen IV in the basement membrane, which normally prevents cancer invasion. TMZ induces DNA damage and activates transcription factors including c-jun, c-fos, nuclear factor-κβ, and early growth response protein-1, which have putative binding sites on the MMP-9 promoter. TMZ may therefore enhance tumour invasion by stimulating MMP-9 transcription and enzymatic activity. To test this hypothesis, we investigated MMP-2 and -9 mRNA transcription and activity in GBM cell lines treated with TMZ. Human A172 GBM cells were exposed to TMZ (25% and 50% inhibitory concentrations) for 24 or 48h; cell cycle distribution and mRNA levels of MMP-2 and -9 were evaluated using flow cytometry and semi-quantitative reverse transcription PCR, respectively. MMP-2 and -9 enzymatic activities were assessed using gelatin zymography in human A172 and U373 MG GBM cells exposed to TMZ under the same conditions. TMZ altered A172 cell cycle distribution, but not MMP-2 or -9 mRNA levels. TMZ did not affect MMP-2 or -9 enzymatic activities in A172 or U373 MG cells. These findings indicated that TMZ is therefore unlikely to promote GBM invasiveness.

Abstract
For serving green tea, there are two prominent methods: steeping the leaf or the powdered leaf (matcha style) in hot water. The purpose of the present study was to reveal chemical and functional differences before and after the powdering process of green tea leaf, since powdered green tea may contribute to expanding the functionality because of the different ingesting style. In this study, we revealed that the powdering process with a ceramic mill and stirring in hot water increased the average extracted concentration of epigallocatechin gallate (EGCG) by more than three times compared with that in leaf tea using high-performance liquid chromatography (HPLC) and liquid chromatography-tandem mass Spectrometry (LC-MS/MS) analyses. Moreover, powdered green tea has a higher inhibition effect of reactive oxygen species (ROS) production in vitro compared with the same amount of leaf tea. Our data suggest that powdered green tea might have a different function from leaf tea due to the higher catechin contents and particles.

Abstract
Cell division, during which a mother cell usually divides into two daughter cells during one cell cycle, is the most important physiological event of cell biology. We observed one-to-four cell division during imaging of live SW1736 human thyroid anaplastic carcinoma cells transfected with a plasmid expressing the hybrid protein of green fluorescent protein and histone 2B (plasmid eGFP-H2B). Analysis of the images revealed a mother cell divided into four daughter cells. And one of the abnormally divided daughter cells subsequently formed a dinucleate cell.

Abstract
BACKGROUND Transduction of foreign molecules into cells is an important technique to investigate the functions of corresponding molecules and/or targets. Recently, a mass-producible nanoprinting perforator was devised enabling for large-scale, high-performance drug or nucleic-acid transfer into cells without cell damage. Since little is known on the performance of the system, we investigated its effects on a malignant glioma cell line. MATERIALS AND METHODS Photosensitization was performed by the Cell Stamper CP-01. The malignant U373MG glioma cell line was used for transduction. RESULTS Photosensitization transduced FITC-conjugated albumin into cells. Trypan blue inclusion test demonstrated membrane disintegration by the procedure and scanning electron microscopy disclosed perforation of the cell membrane. CONCLUSION Local oxidation reaction during the nanoprinting caused reversible membrane perforation. Morphological findings from the current study support the above mechanism, therefore the specific printing system might be convenient for transduction of foreign molecules into malignant glioma cells.

Abstract
Recent advances in genomic technology and genome-wide analysis have identified key molecular alterations that are relevant to the diagnosis and prognosis of brain tumors. Molecular information such as mutations in isocitrate dehydrogenase (IDH) genes or 1p/19q co-deletion status will be more actively incorporated into the histological classification of diffuse gliomas. BRAF V600E mutations are found frequently in circumscribed low-grade gliomas such as pleomorphic xanthoastrocytoma (PXA) and extra-cerebellar pilocytic astrocytoma, or epithelioid glioblastomas (E-GBM), a rare variant of GBM. This mutation is relatively rare in other types of diffuse gliomas, especially in adult onset cases. Here, we present an adult onset case of IDH wild-type/BRAF V600E-mutated diffuse glioma, evolving from grade III to grade IV. The tumor displayed atypical exophytic growth and had unusual histological features not fully compatible with, but indicative of PXA and E-GBM. We discuss differential diagnosis of the tumor, and review previously described diffuse gliomas with the BRAF V600E mutation.

Abstract
The present study investigated the relationship between microRNA-203 (miR-203) and the p53 upregulated modulator of apoptosis (Puma) in colon (HCT116) and lung cancer (A549) cells. Colon and lung cancer cell lines were selected for this study since a relationship between p53/miR-203 and p53/Puma has been established in both cancers. In the present study, adriamycin and nutlin-3 were used to activate p53, which induced both miR-203 and Puma expression in HCT116 cells. In contrast, HCT 116 cells with downregulated p53 showed decreased miR-203 and Puma expression. Importantly, we found that overexpressed miR-203 in HCT116 cells resulted in significantly increased Puma expression (P<0.05). Based on these findings, we hypothesized that another limb of the p53/Puma axis depends on miR-203 expression. To further validate this relationship, we used lung cancer cells (A549) and found that activated p53 increased both miR-203 and Puma expression. In addition, we found that Puma expression remained elevated in cells with overexpressed miR-203 in the presence of p53 downregulation. Cumulatively, our data purport that p53 not only increased Puma expression directly, but that it may also do so through miR-203. Additionally, functional studies revealed that miR-203 overexpression induced apoptosis and inhibited cell invasiveness.

Abstract
Corticotropin-releasing factor (CRF) and its family of peptides, i.e., urocortins (UCNs), play a critical role in systemic and peripheral stress-response systems and are widely expressed not only in normal tissues but also in various types of cancer cells. Given limited understanding of the mechanism of UCN I secretion, we investigated the UCN I secretory pathway in human neural stem cells (HNSCs) and in two glioblastoma cell lines, e.g., A172 and U-138 MG. Immunoreactivities for CRF receptors were detected in A172 glioblastoma cells, but not in HNSCs or U-138 glioblastoma cells, while UCN I immunoreactivity was detected in A172 and U-138 MG glioblastoma cell lines by both light field and electron microscopy. Interestingly, electron microscopy revealed UCN I immunoreactivtiy in vesicle-like structures in the plasma membrane of the glioblastoma cells. Tracking of a hybrid fluorescent protein containing a UCN I signal peptide expressed in A172 human glioblastoma cells revealed that fluorescence in secretory granules could be decreased by cycloheximide (100μg/ml), indicating that the forward transport of secretory granules containing fluorescent protein was not altered by the inhibition of protein synthesis by cycloheximide. Retrograde transport and the fusion of fluorescent granules in A172 human glioblastoma cells was induced by brefeldin A (10μg/ml), indicating that UCN I secretory granules may be transported via the constitutive pathway. Based on these results, it appears that UCN I is secreted from human glioblastoma cells by exocytosis through constitutive secretory granules, indicating that transcription of UCN I mRNA may be correlated to secretion of UCN I protein.

Abstract
Cholangiocarcinoma is a disease with a poor prognosis. A human cholangiocarcinoma cell line, TK, was previously established to enable further understanding of the disease. We conducted this investigation to determine whether or not the TK line is useful for pharmacokinetic study of the chemotherapeutic agent gemcitabine (GEM). Along with the BXPC3 human pancreatic adenocarcinoma cell line, the sensitivity to and effects on the TK cell line of GEM were compared. The influence of deoxycytidine kinase (dCK) transduction was also comparatively investigated. The effects of GEM in terms of drug sensitivity of the TK cell line, cell cycle and levels of transcripts of key enzymes were comparable to the BXPC3 cell line. Responses to the drug were similar in both cell lines. In contrast to pancreatic carcinoma, cell lines for research on cholangiocarcinoma have been limited. This study suggests the application of the TK cell line to the pharmacokinetic study of the chemosensitization of therapeutic drugs, such as GEM.

Abstract
Cholangiocarcinoma is an intractable carcinoma originating from the bile duct epithelium. To gain an understanding of the cell biology of cholangiocarcinoma, in vitro cell culture is valuable. However, well‑characterized cell lines are limited. In the present study, the morphology of the TK cholangiocarcinoma cell line was analyzed by three‑dimensional culture. Dispersed TK cells were injected into a gelatin mesh scaffold and cultivated for 3‑20 days. The morphology of the TK cells was investigated by phase‑contrast microscopy, optical microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). TK cells were observed to proliferate three-dimensionally in the scaffold. The cells exhibited a globoid structure and attached to the scaffold. The SEM observation demonstrated typical microvilli and plicae on the surface of the structure. Light microscopy and TEM confirmed intercellular and cell‑to‑scaffold attachment in the three‑dimensional mesh. The culture also exhibited the formation of a duct-like structure covered by structured microvilli. In conclusion, three‑dimensional culture of TK cells demonstrated the morphological characteristics of cholangiocarcinoma in vitro. Production of high levels of carbohydrate antigen (CA)19‑9, CA50 and carcinoembryonic antigen was previously confirmed in the TK cell line. As a characteristic morphology was demonstrated in the present study, the TK cholangiocarcinoma cell line may be useful as an experimental model for further study of cholangiocarcinoma.

Abstract
The possibility of nanoparticle (NP) uptake to the human central nervous system is a major concern. Recent reports showed that in animal models, nanoparticles (NPs) passed through the blood–brain barrier (BBB). For the safe use of NPs, it is imperative to evaluate the permeability of NPs through the BBB. Here we used a commercially available in vitro BBB model to evaluate the permeability of NPs for a rapid, easy and reproducible assay. The model is reconstructed by culturing both primary rat brain endothelial cells and pericytes to support the tight junctions of endothelial cells. We used the permeability coefficient (Papp) to determine the permeability of NPs. The size dependency results, using fluorescent silica NPs (30, 100, and 400 nm), revealed that the Papp for the 30 nm NPs was higher than those of the larger silica. The surface charge dependency results using Qdots® (amino-, carboxyl-, and PEGylated-Qdots), showed that more amino-Qdots passed through the model than the other Qdots. Usage of serum-containing buffer in the model resulted in an overall reduction of permeability. In conclusion, although additional developments are desired to elucidate the NPs transportation, we showed that the BBB model could be useful as a tool to test the permeability of nanoparticles.

Abstract
BACKGROUND Papillary thyroid carcinoma often has lymph node metastasis, compared with follicular thyroid carcinoma. The study showed that epithelial-mesenchymal transition occurs in carcinoma cells during the first stage of metastasis, where some extracellular matrix molecules are secreted in large quantities. Sialic acid carried by fibronectin as the antigen of the monoclonal antibody (MoAb) JT-95, was detected in 90% of papillary thyroid carcinoma cases, and in a few follicular thyroid carcinomas, in the extracellular matrix of thyroid carcinoma cells. OBJECTIVES The current study was conducted to investigate the association between increasing the number of extracellular matrix molecules, fibronectin, and lymph node metastasis. We also co-cultured a thyroid carcinoma cell line and lymphocyte cell line, with and without MoAb JT-95, in order to investigate the mechanism of cell to cell interaction. PATIENTS AND METHODS Immunostaining with JT-95 was performed in 45 papillary thyroid carcinoma cases, and 20 follicular type tumors, to investigate the association between the quantity of fibronectin expression and the frequency of lymph node metastasis. The thyroid carcinoma cell line (SW1736), which secreted fibronectin, and the B cell-lymphoma cell line (Daudi), which held integrin on the cell surface, were co-cultured to observe the adhesion of cells to each other. The SW1736 cell line, pretreated with JT-95, was also co-cultured with the Daudi cell line. RESULTS There were 39 cases with lymph node metastasis in 59 malignant tumors, and 0 cases in 6 benign follicular type tumors. The staining scores by JT-95 of the 39 tumors with lymph node metastasis were 5+ in eight cases and 6+ in 31 cases. On the other hand, the scores of 20 malignant tumors without lymph node metastasis were < 4+ in all of the cases. In the co-cultured assay, numerous adhesions were observed between the SW1736 and Daudi cells. In contrast, the inhibition of adherences was observed in proportion to the concentrations of JT-95. CONCLUSIONS Increased fibronectin expression in thyroid malignancies is correlated with lymph node metastasis.

Abstract
BACKGROUND Urocortin is analogous to corticotrophin-releasing factors (CRFs) and a member of the CRF family. We previously demonstrated that urocortin mRNAs were expressed in both human and rat glioma cell lines, and that some of these lines transcribed the receptors. We hypothesize that urocortin might also be expressed in a gastric cancer cell line. The aim of the present study was to clarify the expression of mRNAs of urocortin1 (UCN1), -2 and -3 and of CRF and CRF receptors 1 and 2 in a gastric cancer cell line. MATERIALS AND METHODS STKM-1 a poorly-differentiated adenocarcinoma cell line was used. Transcripts in the cells were analyzed using cDNA. The fluctuation of mRNA with cellular stress, such as the one caused by a chemotherapeutic agent, serum supplementation and forskolin was examined. RESULTS Transcripts of UCN1, -2 and CRFR2 were expressed. No changes in transcription of UCN1 and UCN2 were observed with cellular stress. However, expression of CRFR2 mRNA transcripts significantly increased after an initial 24-h exposure to forskolin. CONCLUSION Expression of the mRNAs of UCN1, 2 and CRFR2 was confirmed in the human gastric cancer cell line, STKM-1. Although the quantity of CRFR2 transcripts varied with forskolin, the overall transcription pattern was not influenced by cellular stimuli.

Abstract
Electronic noses have the benefit of obtaining smell information in a simple and objective manner, therefore, many applications have been developed for broad analysis areas such as food, drinks, cosmetics, medicine, and agriculture. However, measurement values from electronic noses have a tendency to vary under humidity or alcohol exposure conditions, since several types of sensors in the devices are affected by such variables. Consequently, we show three techniques for reducing the variation of sensor values: (1) using a trapping system to reduce the infering components; (2) performing statistical standardization (calculation of z-score); and (3) selecting suitable sensors. With these techniques, we discriminated the volatiles of four types of fresh mushrooms: golden needle (Flammulina velutipes), white mushroom (Agaricus bisporus), shiitake (Lentinus edodes), and eryngii (Pleurotus eryngii) among six fresh mushrooms (hen of the woods (Grifola frondosa), shimeji (Hypsizygus marmoreus) plus the above mushrooms). Additionally, we succeeded in discrimination of white mushroom, only comparing with artificial mushroom flavors, such as champignon flavor and truffle flavor. In conclusion, our techniques will expand the options to reduce variations in sensor values.

Abstract
Spinal tuberculosis is a condition characterized by massive resorption of the spinal vertebrae due to the infection with Mycobacterium tuberculosis (Mtb). However, the pathogenesis of spinal tuberculosis has not been established because it was almost completely eradicated by the establishment of antibiotic treatment in the mid-20th century. In this study, we investigated the inflammatory responses of human multinucleated osteoclasts infected with virulent Mtb strain. We found that the intracellular Mtb infection of multinuclear osteoclasts resulted in the rapid growth of Mtb and an osteolytic response, rather than inflammation. In response to Mtb infection, the mononuclear osteoclast precursors produced proinflammatory cytokines including tumor necrosis factor (TNF)-α, an intrinsic characteristic they share with macrophages. In contrast, highly fused multinucleated osteoclasts incapacitated the production of these cytokines. Instead, the intracellular Mtb inside multinuclear osteoclasts escaped from the endosome/phagosome, leading to a different pattern of osteoclast activation, with the production of chemokines such as CCL5, CCL17, CCL20, CCL22, CCL24, and CCL25. Moreover, intracellular infection with an avirulent Mtb strain resulted in diminished production of these chemokines. These findings indicate that intracellular Mtb infection in multinuclear osteoclasts reprograms osteoclast development via the dysregulation of cytokines and chemokines.

Abstract
BACKGROUND Urocortin and corticotropin-releasing factors (CRFs) and their receptors are expressed in many organs, including the central nervous system. In this study, the expression of mRNAs of urocortin 1, 2, 3, and CRF and CRF receptors 1 and 2 in malignant glioma, was examined. MATERIALS AND METHODS The RNAs of human and rat glioma cell lines were isolated. Transcripts in these cells were analyzed using cDNA. In addition, the effects of proliferative and cytotoxic stimulation by serum supplementation, ionizing radiation, and the antineoplastic agent temozolomide were investigated. RESULTS Human and rat cells transcribed urocortin. CRF receptors were detected in human glioma cells. When human KNS42 cells were exposed to stimulation, transcription was altered according to the specific condition. CONCLUSION Expression of mRNAs of urocortin and CRF receptors was confirmed in human glioma cell lines. Although the quantities of transcripts varied with the proliferative and cytotoxic stimulation, the overall transcription pattern was not influenced by these stimuli.

Abstract
BACKGROUND We have established a mouse model of spontaneous deafness by sib-inbreeding over 10 years. The mouse was designated as kuru(2) and has been previously reported in this Journal. MATERIALS AND METHODS In order to identify the genetic abnormality, the mouse was back-crossed to Mus musculus castaneus (CAST), and myosine 15 or myoXV on chromosome 11 was assumed to be the responsive gene. The background abnormality was identified by gene sequencing. RESULTS Deletion of 2446 base pairs occurred in the mouse (from 28795 to 31241 in the complete sequence of the Mus musculus unconventional myosin-15 gene; NCBI accession: AF144093). DISCUSSION The myosin ATP-binding site is present in the deleted area. Considering the function that the affected area regulates and previous reports, hearing loss of the examined mouse is attributable to the abnormality of the myoXV gene and this mouse might be another type of shaker-2 deaf mouse.

Abstract
Tetrahydrouridine (THU) is a well characterized and potent inhibitor of cytidine deaminase (CDA). Highly expressed CDA catalyzes and inactivates cytidine analogues, ultimately contributing to increased gemcitabine resistance. Therefore, a combination therapy of THU and gemcitabine is considered to be a potential and promising treatment for tumors with highly expressed CDA. In this study, we found that THU has an alternative mechanism for inhibiting cell growth which is independent of CDA expression. Three different carcinoma cell lines (MIAPaCa-2, H441, and H1299) exhibited decreased cell proliferation after sole administration of THU, while being unaffected by knocking down CDA. To investigate the mechanism of THU-induced cell growth inhibition, cell cycle analysis using flow cytometry was performed. This analysis revealed that THU caused an increased rate of G1-phase occurrence while S-phase occurrence was diminished. Similarly, Ki-67 staining further supported that THU reduces cell proliferation. We also found that THU regulates cell cycle progression at the G1/S checkpoint by suppressing E2F1. As a result, a combination regimen of THU and gemcitabine might be a more effective therapy than previously believed for pancreatic carcinoma since THU works as a CDA inhibitor, as well as an inhibitor of cell growth in some types of pancreatic carcinoma cells.

Abstract
The effects of corticotropin-releasing hormone, also known as corticotropin-releasing factor (CRF), on the cardiovascular system have been intensively researched since its discovery. Moreover, the actions of urocortin (Ucn) I on the cardiovascular system have also been intensively scrutinized following the cloning and identification of its receptor, CRF receptor type 2 (CRFR2), in peripheral tissues including the heart. Given the cardioprotective actions of CRFR2 ligands, the clinical potential of not only Ucn I but also Ucn II and III, which were later identified as more specific ligands for CRFR2, has received considerable attention from researchers. In addition, recent work has indicated that CRF type 1 receptor may be also involved in cardioprotection against ischemic/reperfusion injury. Here we provide a historical overview of research on Ucn I and related agents, their effects on the cardiovascular system, and the clinical potential of the use of such agents to treat cardiovascular diseases.

Abstract
Aldosterone, a specific mineralocorticoid receptor (MR) agonist and a key player in the development of hypertension, is synthesized as a final product of renin-angiotensin-aldosterone system. Hypertension can be generally treated by negating the effects of angiotensin II through the use of angiotensin-converting enzyme inhibitors (ACE-Is) or angiotensin II type 1 receptor antagonists (ARBs). However, the efficacy of angiotensin II blockade by such drugs is sometimes diminished by the so-called "aldosterone breakthrough" effect, by which ACE-Is or ARBs (renin-angiotensin system (RAS) inhibitors) gradually lose their effectiveness against hypertension due to the overproduction of aldosterone, known as primary aldosteronism. Although MR antagonists are used to antagonize the effects of aldosterone, these drugs may, however, give rise to life-threatening adverse actions, such as hyperkalemia, particularly when used in conjunction with RAS inhibitors. Recently, several groups have reported that some dihydropyridine Ca(2+) channel blockers (CCBs) have inhibitory actions on aldosterone production in in vitro and in the clinical setting. Therefore, the use of such dihydropyridine CCBs to treat aldosterone-related hypertension may prove beneficial to circumvent such therapeutic problems. In this paper, we discuss the mechanism of action of CCBs on aldosterone production and clinical perspectives for CCB use to inhibit MR activity in hypertensive patients.

Abstract
BACKGROUND Malignant glioma is an invasive disease of the central nervous system. One of the factors that regulate growth of these tumors is expression of epidermal growth factor receptor (EGFR) in the cells. This study investigated the effects of down-regulation of EGFR on cell proliferation, cell cycle and cytotoxicity to antineoplastic agent. MATERIALS AND METHODS A short hairpin RNA transcription vector targeting EGFR was transfected into KNS42 cells. Growth curve, cell cycle and sensitivity to temozolomide of the cells were assessed. RESULTS Transfection inhibited EGFR expression by 50.5%. It prolonged cell doubling time by 25.7%. However, it did not meaningfully alter the cell cycle populations nor increase sensitivity to temozolomide. CONCLUSION Suppressing expression of EGFR inhibited cell proliferation. However, unlike PTEN expression or ROCK1 down-regulation, it did not alter the cell cycle or increase sensitivity to temozolomide.

Abstract
Among the immunoglobulins, IgM class-antibodies are now considered to be potent immunological reagents for anticancer remedies. However, only a few reports are available about the effective labeling of IgM with enzymes, fluorescence, or other bioreactive reagents. Here, we report an effective application of luminescent semiconductive nanoparticles, quantum dots (QDs), as a labeling material of the IgM antibody. The CdSe carboxyl QDs were reacted with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride and N-hydroxysulfo- succinimide in 2-(morpholino) ethanesulfonic acid. The reacted QDs were then coupled to JT95 IgM antibody, which recognizes thyroid carcinoma associated antigen. The specificity and activity of the conjugates were tested by immunoblot, immunoquantitive assay and immunohistological imaging. The QDs were firmly conjugated with JT95 IgM monoclonal antibody. In immunoblot assay, QD-JT95 conjugates directly detected the target molecules without obstructing the binding site. In immunoquantitive assay, the conjugates could quantify the antigen in the range of 1.56-100 μg/mL. Also, QDs-labeled antibody detected the antigen on plasma membrane. Our results demonstrate that labeling of JT95 and other IgM class antibodies with QDs is feasible. This approach may be an important method for the medical application of IgM in the diagnosis and treatment of cancers.

Abstract
BACKGROUND Deletions or mutations of the phosphatase and tensin homolog (PTEN) are frequently observed in malignant glioma and are responsible for progression of the disease. Since the molecule is a promising target for gene therapy, the effects of PTEN on glioma proliferation in combination with the anti-neoplastic agent, temozolomide, and ionizing radiation were investigated. MATERIALS AND METHODS An adenoviral vector encoding PTEN was used. After infection, changes in proliferation, the cell cycle, as well as drug- and radiosensitivity were investigated. RESULTS Expression of PTEN led to a 1.21-fold prolongation of the doubling time of the cells. It reduced G(1) and increased G(2)/M populations. Forced PTEN expression conferred sensitivity to temozolomide and/or ionizing radiation. CONCLUSION In addition to counteracting cell proliferation, expression of PTEN presented advantages in the chemo- and radiosensitivity of glioma cells. Methods for up-regulation of PTEN may have a role in increasing the efficacy of current adjuvant therapies.

Abstract
BACKGROUND Papillary thyroid carcinoma (PTC) is often accompanied by lymph node metastasis (LNM), compared with follicular thyroid carcinoma (FTC). Sialic acid is carried by fibronectin (sFN) as the antigen of monoclonal antibody (MoAb) JT-95 detected in 90% of PTC, and a few cases of FTC. PATIENTS AND METHODS JT-95 staining was performed in 9 PTC and 20 follicular type tumors to investigate the relationship between the expression of sFN and the frequency of LNM. RESULTS There were 11 cases with LNM from 23 malignant tumors, and no cases of LNM from 6 benign follicular type tumors. The staining scores by JT-95 of the 11 tumors with LNM were 5+ in 4 cases, and 6+ in 7 cases. On the other hand, the scores of 12 malignant tumors without LNM were <4+ in all cases. CONCLUSION An increase of sFN expression in thyroid malignancies is correlated with LNM.

Abstract
BACKGROUND Malignant glioma is one of the most intractable diseases in the human body. Rho-kinase (ROCK) is overexpressed and has been proposed as the main cause for the refractoriness of the disease. Since efficacious treatment is required, this study investigated the effect of inhibition of ROCK isoforms. MATERIALS AND METHODS The short hairpin RNA transcription vector was transfected into the RT2 rat glioma cell line and the characteristics of the cells were investigated. The effect of nimustine hydrochloride (ACNU) anti-neoplastic agent on cells was also measured. RESULTS Inhibition of ROCK isoforms did not alter cell growth. Cell cycle analysis revealed that ROCK1 down-regulation reduced the G(0) phase population and ROCK2 down-regulation reduced the G(2)/M phase population. When ROCK1-down-regulated cells were exposed to ACNU, they demonstrated susceptibility to the agent. CONCLUSION The roles of ROCK1 and ROCK2 may be different in glioma cells. Furthermore, the combination of ROCK1 down-regulation and an anti-neoplastic agent may be useful for the therapy of malignant glioma.

Abstract
Chemokines are characterized by the homing activity of leukocytes to targeted inflammation sites. Recent research indicates that chemokines play more divergent roles in various phases of pathogenesis as well as immune reactions. The chemokine receptor, CCR1, and its ligands are thought to be involved in inflammatory bone destruction, but their physiological roles in the bone metabolism in vivo have not yet been elucidated. In the present study, we investigated the roles of CCR1 in bone metabolism using CCR1-deficient mice. Ccr1(-/-) mice have fewer and thinner trabecular bones and low mineral bone density in cancellous bones. The lack of CCR1 affects the differentiation and function of osteoblasts. Runx2, Atf4, Osteopontin, and Osteonectin were significantly up-regulated in Ccr1(-/-) mice despite sustained expression of Osterix and reduced expression of Osteocalcin, suggesting a lower potential for differentiation into mature osteoblasts. In addition, mineralized nodule formation was markedly disrupted in cultured osteoblastic cells isolated from Ccr1(-/-) mice. Osteoclastogenesis induced from cultured Ccr1(-/-) bone marrow cells yielded fewer and smaller osteoclasts due to the abrogated cell-fusion. Ccr1(-/-) osteoclasts exerted no osteolytic activity concomitant with reduced expressions of Rank and its downstream targets, implying that the defective osteoclastogenesis is involved in the bone phenotype in Ccr1(-/-) mice. The co-culture of wild-type osteoclast precursors with Ccr1(-/-) osteoblasts failed to facilitate osteoclastogenesis. This finding is most likely due to a reduction in Rankl expression. These observations suggest that the axis of CCR1 and its ligands are likely to be involved in cross-talk between osteoclasts and osteoblasts by modulating the RANK-RANKL-mediated interaction.

Abstract
BACKGROUND To explore the intracranial behaviors of glioma, a three-dimensional culture was devised and the morphology of four cell lines was examined. MATERIALS AND METHODS Bioabsorbable and degradable gelatin was used as the scaffold and T98G, A172, KNS42, and U118MG representative standard malignant glioma cell lines were cultured three-dimensionally. RESULTS When grown, the cells demonstrated characteristic conformations. The U118MG cells dispersed with numerous fiber formations. In contrast, the KNS42 and A172 cells aggregated, adhering to each other, resulting in the formation of balloon-like structures. The T98G cells demonstrated an intermediate character. CONCLUSION The cell lines showed distinct characteristics in three-dimensional culture. This culture method may have a role in elucidating the fundamental character of cells in the human body.

Abstract
The prognosis of pancreatic cancer remains poor, and the standard first-line chemotherapy with gemcitabine (GEM) has a response rate of less than 20%. Since expression of deoxycytidine kinase (dCK) seems important for improvement of GEM sensitivity, overexpression of dCK was investigated using pancreatic cancer cell lines (Panc-1, MIAPaCa-2 and BxPC-3). dCK gene was introduced into the cell lines by retrovirus and changes in IC50 were examined. Sensitivity of two pancreatic cancer cell lines to GEM elevated dramatically in comparison with control cells, but change of sensitivity remained at 1.8 times in BxPC-3. Since addition of tetrahydro uridine (THU), an inhibitor of deoxycytidine deaminase (CDA), increased the sensitivity 54-fold, overexpression of CDA seems to be the mechanism for improvement of the sensitivity. In conclusion, dCK is a key enzyme of GEM, but resistance of GEM is not improved in all pancreatic cancer cells by overexpression of dCK. Combination treatment based on expression of GEM metabolism-related gene may become an effective therapy in the future.

Abstract
BACKGROUND Smell provides important information about the quality of food and drink. Most well-known for their expertise in wine tasting, sommeliers sniff out the aroma of wine and describe them using beautiful metaphors. In contrast, electronic noses, devices that mimic our olfactory recognition system, also detect smells using their sensors but describe them using electronic signals. These devices have been used to judge the freshness of food or detect the presence of pathogenic microorganisms. However, unlike information from gas chromatography, it is difficult to compare odour information collected by these devices because they are made for smelling specific smells and their data are relative intensities. METHODOLOGY Here, we demonstrate the use of an absolute-value description method using known smell metaphors, and early detection of yeast using the method. CONCLUSIONS This technique may help distinguishing microbial-contamination of food products earlier, or improvement of the food-product qualities.

Abstract
Mars is a CO(2)-abundant planet, whereas early Earth is thought to be also CO(2)-abundant. In addition, water was also discovered on Mars in 2008. From the facts and theory, we assumed that soda fountains were present on both planets, and this affected amino acid synthesis. Here, using a supercritical CO(2)/liquid H(2)O (10:1) system which mimicked crust soda fountains, we demonstrate production of amino acids from hydroxylamine (nitrogen source) and keto acids (oxylic acid sources). In this research, several amino acids were detected with an amino acid analyzer. Moreover, alanine polymers were detected with LC-MS. Our research lights up a new pathway in the study of life's origin.

Abstract
BACKGROUND Malignancies affecting the central nervous system are intractable to conventional therapies thereby requiring an alternative strategy, such as ultrasound irradiation. MATERIALS AND METHODS We originally designed a transducer for intracranial insonation and investigated the effect of 210.4 kHz ultrasound on malignant glioma cells. RESULTS The insonation of 2.61 W/cm2 effectively disrupted the malignant cells. This effect was reinforced by the echo-contrast agent, Levovist. The condition was applied to tumor-bearing animals and external insonation inhibited subcutaneous tumor growth. It also repressed the growth of intracranially implanted tumors and prolonged survival of the animals. When Levovist was stereotactically injected into the tumors, the effect of insonation was significantly enhanced. CONCLUSION A neuronavigation system or stereotactic device has been used commonly for patients with brain tumor. Administration of combination therapy consisting of insonation and a local echo-contrast agent will have a role in improving the treatment for malignant gliomas.
