AbstractThe intracellular suppressors of cytokine signaling (SOCS) family members, including CISH and SOCS1 to 7 in mammals, are important regulators of cytokine signaling pathways. So far, the orthologues of all the eight mammalian SOCS members have been identified in fish, with several of them having multiple copies. Whilst fish CISH, SOCS3, and SOCS5 paralogues are possibly the result of the fish specific whole genome duplication event, gene duplication or lineage specific genome duplication may also contribute to some paralogues, as with the three trout celine bags online SOCS2s and three zebrafish SOCS5s. Fish SOCS genes are broadly expressed and also show species specific expression patterns. They can be upregulated by cytokines, such as IFN TNF IL 1 IL 6, and IL 21, by immune stimulants such as LPS, poly I:C, and PMA, as well as by viral, bacterial, and parasitic infections in member and species dependent manners. Initial functional studies demonstrate conserved mechanisms of fish SOCS action via JAK/STAT pathways. 1. IntroductionCytokines have essential roles in the development, differentiation, and function of the immune response. Following receptor ligation cytokines, including interleukins (ILs), interferons (IFNs), and haematopoietic growth factors, activate the Janus kinase signal transducer and activator of transcription (JAK STAT) pathways to elicit downstream effects in responsive cells. The intracellular suppressors of cytokine signaling (SOCS) family members are emerging as one of the most important regulators of these pathways [1]. So far eight members of the SOCS family, including cytokine inducible SRC homology 2 (SH2 ) domain containing protein (CISH) and SOCS1 have been identified in mammals, all of which are structurally characterized by a central SH2 domain and a conserved C terminal motif named as the SOCS box [2]. Most SOCS proteins are induced by cytokines and therefore act in a classical negative feedback loop to inhibit cytokine signal transduction. However, they are also induced by various other stimuli, such as pathogen associated molecular patterns (PAMPs), and bacterial, viral, and parasitic infection [3]. Many important cytokines have been identified in teleost fish in the last decade aided by the sequenced genomes of a few model teleosts, that is, tetraodon (Tetraodon nigroviridis), zebrafish (Danio rerio), fugu (Takifugu rubripes), stickleback (Gasterosteus aculeatus), and medaka (Oryzias latipes), and large expressed sequence tag (EST) projects in a few economically important species such as the salmonids Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) [4]. The cytokines discovered in teleosts include proinflammatory cytokines such as IL 1 IL 6, IL 8, IL 11, and tumour necrosis factor (TNF and anti inflammatory cytokines such as IL 10, transforming growth factor (TGF and a novel IL 1 family member discovered in fish that antagonises the activity of IL 1 [4]. Important initiators and effectors of adaptive immune responses have also been cloned, such as IL 2, IL 4/13 like, IL 7, IL 12, IL 15, IL 17 family members, IL 18, IL 20, IL 21, IL 22, type I IFNs, and IFN [5]. The recombinant proteins have been produced for a few of these cytokines, for example, IL 1 [6], IL 2 [7], IL 6 [8], IL 8 [9], IL 10 [10], IL 4/13 like, IL 15 [11], IL 21 [12], IL 22 [13], TNF [14, 15], type I IFNs [16], and IFN [17, 18], to begin to validate their functional relevance. Most recently the fish immunology research community has begun to elucidate the negative regulators of cytokine signalling. All the mammalian SOCS family members have been identified in fish, with some additional novel teleost members that have likely resulted from fish specific gene/genome duplication events [19]. In this paper, we will first describe the SOCS family members that have been discovered in fish and present new data on the cloning of additional members, that is, CISHb and two further SOCS2 sequences, in rainbow trout. The relationship between the proposed fish SOCS8 and CISH, and fish SOCS9 and SOCS5 will then be discussed. Next results on the expression of fish SOCS genes will be presented, with a focus on new data on the modulation of SOCS gene expression by viral, bacterial, and parasitic infections in salmonids. Finally, the possible function of fish SOCS proteins in the context of duplicated cytokines and SOCS molecules in fish will be discussed. 2. Fish SOCS Gene Discovery2.1. Fish CISH and SOCS8CISH genes have been described in the five model fish (zebrafish, tetraodon, fugu, medaka, and stickleback) for which a genome sequence is available [20], as well as in rainbow trout [21]. CISH sequences have also been submitted to the database from Atlantic salmon (Salmon, acc. nos. B9EPA9 and B5XCB4), rainbow smelt (Osmerus mordax) (Smelt, acc. no. C1BIN3), and grass carp (Ctenopharyngodon idella) (gCarp, acc. no. D3Y197). Another sequence has also been described in the five model fish that has high homology to CISH and was designated as fish specific SOCS8 based on its predicted unique gene organisation. The CISH genes in tetrapods and fish have a three (coding) exon/two intron gene organization, whilst the fish SOCS8 was believed to be encoded by two exons, with an intron in the 5 region (UTR) [20]. Both fish CISH and SOCS8 molecules as well as tetrapod CISH have similar domain structures including the central SH2 domain and the C terminal SOCS box (Figure 1(a)). Figure 1 Gene organisation and domain structure of CISH (a), SOCS2 (b), SOCS5 (c), and other human SOCS molecules (d). The gene organisation is extracted from the publication by Jin et al. The accession hermes gpe numbers of the protein sequences are given in Figure 3. To isolate the trout SOCS8 gene, primers were designed at the 5 of the sockeye salmon sequence and used for 3 using trout liver SMART cDNA as described previously [23, 24]. A 1.2kb band (as revealed on an agarose gel) was amplified, cloned, and sequenced, which contained a partial 5 an ORF for 233 amino acids (aa), and the 3 with a poly A signal 13bp upstream of the poly A tail (acc. no. {"type":"entrez nucleotide","attrs":{"text":"FR873795","term_id":"512388806","term_text":"FR873795"}}FR873795). The trout translation showed 98.7% identity to the sockeye salmon sequence as calculated using the MatGAT program [25]. Both the trout and sockeye translations showed similar identities (49.5 Table 1) to CISH and SOCS8 molecules from the model fish but highest identities (55.0 to CISH from salmonids. The tetrapod CISHs share comparable identities to both fish CISH (36.8 and fish SOCS8 (37.5 Table 1). Thus, the homology analysis (shown in Table 1) does not sufficiently separate the celine handbags fish CISH and SOCS8 into two categories but rather they appear to be fish paralogues of tetrapod CISH. From new evidence on the SOCS8 gene organisation, synteny, and phylogenetic tree analysis that will be described below, we suggest to rename the so called fish SOCS8 as CISHb and the published fish CISH as CISHa. The SH2 domain and SOCS box are critical for SOCS function. The SH2 domain in CISH and SOCS2 binds to a cytokine receptor cytoplasmic domain to compete with STAT SH2 domains for specific receptor phosphotyrosine residues. The SOCS box motif, by binding to an E3 ubiquitin ligase complex, ubiquitinates the associated proteins targeting them for proteasomal degradation [26]. In addition, the kinase inhibitory region (KIR) located at the N terminal and adjacent to the SH2 domain in SOCS1 and 3 is required for inhibition of JAK kinase activity [27], and the extended SH2 domain (ESS) is critical for phosphotyrosine binding [28]. The ESS forms a 15 residue alpha helix, which directly contacts the phosphotyrosine binding loop and determines its orientation. An alignment of selected molecules from tetrapod CISH and fish CISHa and CISHb was produced using ClustalW2 software [29]. A good conservation was seen at the KIR, ESS region, the SH2 domain, and the SOCS box among all the molecules from tetrapods and fish (Figure 2). It is noticeable that the N terminal is quite divergent between CISH molecules from mammals, birds, amphibians, and fish, as is the PEST domain. PEST sequences are rich in proline (P), glutamate (E), serine (S), and threonine (T) and are thought to signal for rapid proteolytic degradation [30]. Several mammalian SOCS proteins contain putative PEST sequences [31] suggesting a common mechanism for regulation of SOCS protein levels. Figure 2 Alignment of CISH molecules from selected tetrapod and fish species. The multiple alignment was produced using the ClustalW2 program and box shaded. Dashes ( indicate gaps in the alignment. It is likely that the trout and sockeye salmon CISHb gene will have a similar gene organisation to that seen in tetraodon in light of the aa length. However, we could not confirm this gene organisation in fugu, a close relative of tetraodon, as well as in zebrafish, medaka, and stickleback that may indeed only have two coding exons as predicted by Jin et al. [20]. Thus, the CISHb genes in these species encode an N terminal shortened CISH paralogue. To confirm the relationship among the SOCS family members, an unrooted maximum likelihood (ML) tree (Figure 3) was inferred using MEGA software [32] with the Jones Thornton Taylor (JTT) aa matrix and all sites. The tree contained all the known full length fish SOCS molecules and selected tetrapod SOCS members. As seen in the ML tree, all the fish CISHa and CISHb grouped together to form an independent clade and grouped with tetrapod CISH molecules with high bootstrap support (90%), suggesting that the fish CISHa and CISHb/SOCS8 are indeed paralogues of tetrapod CISH. Figure 3 An unrooted maximum celine phantom likelihood (ML) phylogenetic tree of the SOCS family members from tetrapods and fish. The tree was constructed based on a multiple alignment of all the known fish SOCS family members and selected molecules from mammals, amphibians,. A TWF2 (twinfilin, actin binding protein, homolog 2 ) like gene is closely linked with both CISH and SOCS8 genes in both zebrafish and medaka, with hermes h belt price the same transcriptional direction. The TWF2 gene is also closely linked to CISH in human Ch 2 (Figure 4). In addition, a HEMK1 gene is also closely linked and with the reverse transcriptional direction to CISHs in human Ch 2, medaka Ch 5, and zebrafish Ch6. celine bag nordstrom Many people A replacement continuously growing phenomenon Exactly how really should Locate celine bag nordstrom Tend to be the following Which have Undoubtedly Write-up
