PURPOSE: The expression of Nitric oxide Synthase (NOS) and aquaporin (AQP) water channels in rat bladder is recently reported. The aim of this study is to evaluate the expression of inducible NOS (iNOS), aquaporin-3 (AQP-3) in cyclophosphamide (CYP) induced rat bladder. MATERIALS AND METHODS: The 32 Sprague-Dawley rats were divided into cystitis group (n=20) and control group (n=12). In cystitis group, 100mg/kg CYP was injected every second day for 1 week whereas in control group, normal saline was injected. After extracting of the bladder and dividing dome, body and trigone of the bladder, independently H&E staining and immunohistochemical staining for iNOS and AQP-3 were performed. Expressions of iNOS and AQP-3 were analyzed with a confocal laser scanning microscope and an image analyzer. RESULTS: The expression of iNOS significantly increased in the mucosa, submucosa layer of dome in cystitis group (p<0.05). The expression of AQP-3 significantly increased in the mucosa, submucosa, vessel layer of dome in cystitis group (p<0.05). CONCLUSIONS: These results suggest that inflammatory change activates NOS and AQP-3 expression in the bladder tissue of rats. These may imply that NOS and AQP-3 have a pathophyiological role in the cyclophophamide induced interstitial cystitis. Further study on the NOS and AQP-3 in bladder is needed for clinical application.

Japanese encephalitis (JE) is a mosquito-borne zoonotic disease that affects approximately 50,000 people annually in Asia, causing 10,000 deaths. Considering the role of pigs as the virus-amplifying host and the economic loss in the swine industry, JE is an important disease for both public and animal health. A nationwide JE virus (JEV) vaccination program has been conducted annually for more than 30 years to prevent severe reproductive disorders in the Korean sow population. Remarkable progress in molecular biology has made it possible to analyze the genome of the vaccine strain at the nucleotide and amino acid levels. However, the scientific record of the current JEV veterinary vaccine has not been reported. Therefore, this article outlines the current JEV vaccine strain used in animals and discusses future directions for developing new veterinary JEV vaccines.

Objective To evaluate effects of sirolimus(a classic autophagy inducer)and starved culture on autophagy of a human cutaneous squamous cell carcinoma cell line A431. Methods Cultured A431 cells and HeLa (a human cervical carcinoma cell line)cells were both classified into 5 groups to be treated with DMEM alone(control group), 0.1%dimethyl sulfoxide alone(DMSO group), 20 nmol/L sirolimus(20?nmol/L sirolimus group), 80 nmol/L sirolimus(80?nmol/L sirolimus group), and Earle′s balanced salt solution(EBSS group)respectively. After 4?hour treatment, Western blot analysis was performed to measure the expressions of autophagy?related markers microtubule?associated protein 1 light chain 3A/3B (LC3A/B) and recombinant gamma?aminobutyric acid receptor associated protein(GABARAP), and acridine orange staining to determine autophagy levels in these cells. Results As Western blot analysis showed, the ratio of LC3A/B?Ⅱto LC3A/B?Ⅰin A431 cells was similar between the control group and DMSO group(P > 0.05), but significantly higher in the 20?nmol/L sirolimus group, 80?nmol/L sirolimus group and EBSS group than in the control group(all P < 0.05). Western blot results from HeLa cells were similar to those from A431 cells. Bivariate correlation analysis revealed that the protein expression of GABARAP was positively correlated with that of LC3A/B ?Ⅰ in both HeLa cells(r = 0.869, 95% CI: 0.807 - 0.999, P = 0.051)and A431 cells(r = 0.837, 95% CI: -0.173 - 0.989, P = 0.037), but negatively correlated with that of LC3A/B?Ⅱ in both HeLa cells(r = -0.742, 95% CI: -0.982 - 0.406, P = 0.042)and A431 cells(r = - 0.684, 95% CI: -0.977 - 0.500, P = 0.047). Acridine orange staining showed that the percentages of autophagosome?positive A431 cells and HeLa cells were significantly increased in both the 80?nmol/L sirolimus group(23.750% ± 0.260% and 33.307% ± 0.715% respectively)and EBSS group(32.450% ± 0.488% and 66.097% ± 1.141% respectively) compared with the control group(15.987% ± 0.242% and 14.117% ± 0.295%, respectively, all P < 0.05). Conclusion The classic autophagy inducer sirolimus and starved culture can upregulate the autophagy level of A431 cells, and GABARAP may be highly correlated with LC3A/B.

OBJECTIVETo access the feasibility of employing metabonomics method in clinical studies. This pilot study intends to introduce nuclear magnetic resonance (NMR)-based metabonomics method to elucidate the metabolism of non-syndromic cleft lip and/or palate (NSCLP) patients.
METHODSHigh-resolution 1H NMR spectroscopy was performed on blood plasma obtained from NSCLP and non-malformed children. All signal of 1H NMR spectra were recognized within MESTRE-v4.7, and the 1H NMR spectra integration into bins (or buckets) across the spectral regions of bin 0.04 was performed automatically in MESTRE-v4.7. The resulting data matrix was further analyzed, which was performed by SIMCA-P 11.0. The principal component analysis (PCA) was applied to the centered data to explore any clustering behavior of the samples.
RESULTSThe results demonstrated the metabonomic difference in plasma between NSCLP and non-malformed children at least lies in 3-Hydroxybutyrate gamma-CH3, arginine and valine. Arginine excretion appeared to be higher in the non-malformed children population, while NSCLP population excreted higher concentrations of 3-Hydroxybutyrate gamma-CH3 and valine.
CONCLUSIONThe present study clearly demonstrated the great potential of the NMR-based metabonomics approach in elucidating the NSCLP plasma metabolism and the possibility of application in clinic diagnosis and screening.

OBJECTIVETo investigate the changes of gene expression file in transitional cell carcinoma of bladder after hepatocyte cell adhesion molecule(hepaCAM) overexpression.
METHODSAffymetrix Human Genome U133 Plus 2.0 Array was used to investigate the changes of gene expression profile between adenovirus-green fluorescent protein(GFP) -hepaCAM group and GFP group in transitional cell carcinoma of bladder EJ cells.Significant Analysis of Microarray(SAM) was used to screen the differentially expressed genes, DAVID software was used to conduct gene ontology analysis and wikiPathway analysis based on the differentially expressed genes. Reverse transcription-polymerase chain reaction and Western blot were applied to verify microarray data.
RESULTSCompared with the GFP group, a total of 2469 genes were up-regulated or down-regulated by more than 2 times in the GFP-hepaCAM group. Among these genes, 1602 genes were up-regulated and 867 were down-regulated.Most of the differentially expressed genes were involved in the function of cell proliferation and cell cycle regulation. The mRNA expressions of nibrin, liver kinase B1, and cyclin D1 detected by reverse transcription-polymerase chain reaction in three different bladder cancer cell lines were consistent with the microarray data.The protein expressions of nibrin and liver kinase B1 in these three cell lines measured by Western blot were consistent with the mRNA expression.
CONCLUSIONSHepaCAM can alter the gene expression profile of bladder cancer EJ cells. The well-known anti-tumor effect of hepaCAM may be mediated by regulating the gene expression via multiple pathways.

The purpose of this retrospective study was to describe cases of feline intermediate- to high-grade alimentary lymphoma regarding signalment, clinical presentation, laboratory findings, response to therapy (modified 25-week University of Wisconsin–Madison [UW-25] vs. COP [cyclophosphamide, vincristine, prednisone]), toxicosis, and outcomes and to identify prognostic factors. Sixteen cats were treated with chemotherapy protocols. Response rates and survival did not differ statistically between the two protocols. The progression-free interval (PFI) and median survival time (MST) in cats achieving a response to therapy were longer than in those with no response [NR] (complete remission [CR] vs. partial remission [PR] vs. NR; PFI, 124 vs. 49 vs. 12 days, p < 0.001; MST, 361 vs. 118 vs. 16 days, p < 0.001). Clinical stage was another prognostic factor for PFI and MST. The PFI and MST in cats in stage I were longer than in those in other stages (PFI, 107 days vs. 30 days; MST, 193 days vs. 54 days). Hematologic and gastrointestinal toxicosis was mostly low grade. In comparing the modified UW-25 protocol with the COP protocol, there was not much difference in the number of neutropenic episodes and grade levels.
