Abstract
Olive flounder (Paralichthys olivaceus) is one of economically valuable fish species in the East Asia. In comparison with its economic importance, available genomic information of the olive flounder is very limited. The mass mortality caused by variety of pathogens (virus, bacteria and parasites) is main problem in aquaculture industry, including in olive flounder culture. In this study, we carried out transcriptome analysis using the olive flounder gill tissues after infection of three types of pathogens (Virus; Viral hemorrhagic septicemia virus, Bacteria; Streptococcus parauberis, and Parasite; Miamiensis avidus), respectively. As a result, we identified total 12,415 differentially expressed genes (DEG) from viral infection, 1,754 from bacterial infection, and 795 from parasite infection, respectively. To investigate the effects of pathogenic infection on immune response, we analyzed Gene ontology (GO) enrichment analysis with DEGs and sorted immune-related GO terms per three pathogen groups. Especially, we verified various GO terms, and genes in these terms showed down-regulated expression pattern. In addition, we identified 67 common genes (10 up-regulated and 57 down-regulated) present in three pathogen infection groups. Our goals are to provide plenty of genomic knowledge about olive flounder transcripts for further research and report genes, which were changed in their expression after specific pathogen infection.

Abstract
Membrane-bound peptidases play important roles in the regulation of local concentrations of various signalling peptides such as the growth factors, hormones, chemokines and cytokines. That is accomplished by means of their enzyme activity. Recently, membrane-bound peptidases have also been shown to act as receptors, receiving signals from as yet undefined ligands and transducing them into the cell interior. By using either or both of these mechanisms, peptidases interact with fundamental cellular functions: growth, differentiation, activation and death. This study addressed the effects of a T-cell derived cytokine, interferon-gamma (IFN-gamma) on the activity of aminopeptidase N (APN), an ectoenzyme processing several signal peptides. Cells of a myelo-monocytic cell line HL-60 were used as a model system, and APN was assayed at the levels of mRNA, its membrane marker CD13, and the enzyme activity. Regulation of CD13/APN by IFN-gamma was found at all three levels. The direction of regulation was time-dependent: an initial down-regulation seen 24 and 48 hrs after the onset of treatment with IFN-gamma was replaced by an up-regulation after 72 and/or 96 hrs. Up-regulation of CD13/APN observed after 96 hrs was preceded by an up-regulation of APN mRNA reaching its maximum after 72 hrs. The IFN-gamma-induced regulation of APN was due to membrane aminopeptidase N, since it could be completely abrogated by an APN blocking antibody WM-15. The delayed up-regulation of CD13/APN (observed after 72 and/or 96 hrs), required de novo protein synthesis as it could be abrogated by cycloheximide, an inhibitor of protein synthesis. Possible role of endogenous (IFN-gamma-induced) TGF-beta in mediating CD13/APN up-regulation could be excluded, since no TGF-beta was found in supernatants of IFN-gamma treated HL-60 cells. Thus, our data show regulation of CD13/APN on cells of myelo-monocytic origin by a T-cell derived cytokine, IFN-gamma. A similar mechanism might play a role in inflammation.

Abstract
Inhibitors of the enzymatic activity of alanyl-aminopeptidases severely affect growth and typical functions of human peripheral T cells both in vitro and in vivo. The most prominent changes observed include the activation of cellular signal transduction pathways such as MAP kinases Erk1/2 or the Wnt-pathway, a decrease of production and release of "pro-inflammatory" cytokines (IL-2, IL-12) and, most importantly, an induction of expression and release of the immunosuppressive cytokine, TGF-beta1. Similar effects on T cell proliferation and function have been observed in response to inhibition of DPIV, which is strongly suggestive of a functional synergism of APN and DPIV. In support of this hypothesis evidence is provided showing that the simultaneous application of inhibitors of DPIV and APN further enhances the anti-inflammatory and immunosuppressive effects provoked by the inhibition of APN or DPIV alone. Therefore, the simultaneous inhibition of these enzymes represents a promising strategy for the pharmacological therapy of T cell mediated diseases such as autoimmune disease, inflammation, allergy, and allograft rejection.

Abstract
Alanyl aminopeptidase (APN) is a surface-bound metallopeptidase that processes the N-terminals of biologically active peptides such as enkephalins, angiotensins, neurokinins, and cytokines. It exerts profound activity on vital processes such as immune response, cellular growth, and blood pressure control. Inhibition of either APN gene expression or its enzymatic activity severely affects leukocyte growth and function. We show here that oxidoreductase-mediated modulations of the cell surface thiol status affect the enzymatic activity of APN. Additional evidence for the pivotal role of extracellular cysteines in the APN molecule was obtained when substitution of any of these six cysteines caused complete loss of surface expression and enzymatic activity. In contrast, the transmembrane Cys24 appears to have no similar function. Enzymatically inactive cysteine mutants were retained in the endoplasmic reticulum as shown by high-resolution imaging and Endoglycosidase H digestion. In the absence of any crystal-structure data, the demonstration that individual extracellular cysteines contribute to APN expression and function appears to be of particular importance. The data are the first to show thiol-dependent modulation of the activity of a typical surface-bound peptidase at the cell surface, probably reflecting a general regulating mechanism. This may relate to various disease processes such as inflammation or malignant transformation.

Abstract
The metallopeptidase CD13 is expressed on normal myeloid cells of monocytic and granulocytic origin and on the surface of leukemic blasts in most acute myeloid leukemias (AML). To study the mechanisms regulating lineage restricted CD13 expression in AML we determined normalised CD13 mRNA levels in bone marrow cells and peripheral blood cells of 27 AML patients. Cells of bone marrow origin had lower levels of normalised CD13 mRNA than cells of peripheral blood origin, even though fluorescence intensity and fraction of cells expressing CD13 on the surface was unchanged. In particular, AML patients with very low levels of normalised CD13 mRNA in bone marrow cells showed an increase in CD13 mRNA expression in peripheral blood. To evaluate the effects of bone marrow microenvironment on CD13 mRNA expression, we cultured leukemic myeloid cells with and without murine stromal cells. Bone marrow cells with high and low CD13 surface expression that entered the stromal layers all down-regulated CD13 mRNA expression as compared to cells in suspension above. For peripheral blood cells within stromal layers, CD13 mRNA expression was diminished in only 3 out of 6 cases. The ambiguous effect of stromal cells on peripheral blood cells may illustrate a differentiation-dependent response towards stroma. We determined the polyadenylation status of CD13 mRNA for 9 bone marrow aspirates and 7 peripheral blood samples. Polyadenylation was diminished in bone marrow cells from AML patients with low levels of normalised CD13 mRNA, raising the possibility of involvement of mRNA instability in regulation of CD13 mRNA expression in this subgroup of patients.

Abstract
Inhibition of alanyl aminopeptidase (EC 3.4.11.2, aminopeptidase N, CD13) expression, or activity compromise cell proliferation in a number of cell systems [1, 2, 3, 4, 5, 6]. The underlying mechanisms and the molecular components involved have not been identified as yet. In this study we show that inhibition of alanyl aminopeptidase enzymatic activity decreases the proliferation rate of the CD13-positive T cell line Karpas-299. By using the ATLAS cDNA expression array (Clontech) we identified the p42/ERK2 MAP kinase as one downstream target of probestin, a potent inhibitor of alanyl aminopeptidase. Probestin and another specific aminopeptidase inhibitor, actinonin, in addition to their capability of inducing erk-2 mRNA levels, significantly increase p42 phosphorylation state. This is the first report on signal transduction components possibly mediating the growth-modulatory effects of alanyl aminopeptidase inhibitors.

Abstract
In this study we show that the aminopeptidase N of cerebral pericytes (pAPN) associated with the blood-brain barrier (BBB) is downregulated in pericytic cell cultures. This observation is in accordance with previous data describing comparable in vitro effects for BBB-specific enzymes of endothelial or pericytic origin, such as gamma-glutamyl transpeptidase or alkaline phosphatase. By polymerase chain reaction and in situ hybridization we were able to determine that the down-regulation of pAPN occurs at the posttranscriptional level. The mRNA of pAPN was found to be constitutively expressed even when the protein is no longer detectable. Culturing the pericytes in an endothelial cell-conditioned medium allowed pAPN to be reexpressed. However, the reexpression effect depended largely on the culturing conditions of the pericytes. Although purified pericytes deprived of endothelial cells did not reveal a reexpression effect, pericytes that were kept in contact with endothelial cells were able to acquire a pAPN-positive phenotype, indicating that endothelial cells constitute an essential requirement for the in vitro reexpression of pAPN. Astrocytes, however, were insufficient in exerting any reexpression effect.

Abstract
Aminopeptidase N (APN, EC 3.4.11.2) is an ectopeptidase expressed in lung at the apical surface of alveolar type II epithelial cells. Its expression is upregulated during fetal lung development. To begin to understand the regulation of APN expression during lung development, we used the rapid modification of cDNA ends (RACE) to clone the 5' end of the major APN transcript in rat lung and alveolar type II cells. The cloned sequence revealed a unique 135 bp untranslated exon which genomic cloning and restriction mapping indicated was located more than 14 kb upstream from the coding sequence. A 172 bp genomic fragment flanking the untranslated exon produced a high level of expression of a reporter gene in transient transfection assays using a human lung adenocarcinoma cell line. The DNA fragment includes elements known to be important for expression of lung specific proteins, including the surfactant-associated proteins A, B, and C and the Clara cell specific protein. Comparison of the APN genomic sequences and gene structure from human and rat suggests that the exon present in the rat lung transcript may result from the use of a previously uncharacterized APN promoter.
