Toll-like receptors (TLRs) are a group of highly conserved molecules which initiate the innate immune response to pathogens by recognizing structural motifs of microbes. Understanding the changes in chicken Toll-like receptors (ChTLRs) and signal adaptors expression that occur with Eimeria tenella infection will help to elucidate the molecular basis of immune control of coccidiosis caused by Eimeria. The present study detected the dynamic changes in the expression of ChTLRs and associated signal adaptors in the spleen and cecum ofE. tenella-infected chickens during the early stage of infection. The results showed that the expression peak for ChTLRs, MyD88 and TRIF occurred at 12 h post-infection (hpi), ChTLR3, ChTLRI 5 and MyD88 mRNA expression in the spleen ofE. tenella infected chickens were significantly higher (P〈0.05) than that of negative control chickens, and there were similar tendencies of these molecules expression in the cecum and spleen of E. tenella-infected chickens. The expression of MyD88 was upregnlated at four time points in the cecum of E. tenella-infected chickens. The results of this study indicate that ChTLR3, ChTLR15 and MyD88 play a role in young chickens infected with E. tenella. 展开更多

Most of the existing approaches focus on identifying mismatches and synthesizing adaptors at design-time or recently at run-time. However, few works have been proposed to support adaptor reconfiguration when services in the composition evolve due to changes in business needs. To address the deficiencies, the problem of adaptor reconfiguration is targeted in the context of service composition. Firstly, the formal models for describing services and adaptors are presented. Then, under this formalization,the notion of reconfiguration compliance is proposed to determine the validity of an adaptor instance with respect to its history executions and future executions. Based on the notion,the algorithm for reconfiguration analysis of adaptors is presented and it can be used for determining the migratability of an adaptor instance and the corresponding target state of reconfiguration if migratable.Finally,feasibility of the proposed approach is validated on a realistic case study. The proposed approach improves the flexibility of adaptor-based service composition by equipping adaptors with reconfiguration capabilities. 展开更多

Objective: The mucus production is an indicator for the histological grade of mucinous epithelial ovarian cancer (mEOC). In our previous study, Crk expression was targeted in the human ovarian mucinous adenocarcinoma cell line MCAS through RNA interference, resulting in the establishment of Crk knock down cells. These cells exhibited decreased tumorigenic potential both in vitro and in vivo. The purpose of this study was to investigate if there is any change in the capability of forming mucus in these Crk knock down cells. Methods: Cytoplasmic periodic acid Schiff (PAS) staining and particle excluding assay were conducted to assess the mucus formation within and around cells, respectively. Additionally, the amount of mucus formed in tumor lumps from nude mice model was measured following HE and PAS staining. Results: The increased mucus production in Crk knockdown mEOC cells (MCAS) was manifested by increased number of enlarged cells filled with vacuoles-like mucus observed by phase-contrast microscope and cytoplasmic PAS staining; and enhanced mucus secretion was represented by the assembly of pericellular matrix in particle excluding assay and increased mucus area in tumor lumps from nude mice models. Conclusion: The course of carcinogenesis in mEOC is associated with the altered pattern of mucus production and secretion. The adaptor protein Crk is implicated in both pathways. 展开更多

BACKGROUND Adaptor protein,phosphotyrosine interacting with PH domain and leucine zipper 1(APPL1)plays a crucial role in regulating insulin signaling and glucose metabolism.Mutations in the APPL1 gene have been associated with the development of maturity-onset diabetes of the young type 14(MODY14).Currently,only two mutations[c.1655T>A(p.Leu552*)and c.281G>A p.(Asp94Asn)]have been identified in association with this disease.Given the limited understanding of MODY14,it is imperative to identify additional cases and carry out comprehensive research on MODY14 and APPL1 mutations.AIM To assess the pathogenicity of APPL1 gene mutations in diabetic patients and to characterize the functional role of the APPL1 domain.METHODS Patients exhibiting clinical signs and a medical history suggestive of MODY were screened for the study.Whole exome sequencing was performed on the patients as well as their family members.The pathogenicity of the identified APPL1 variants was predicted on the basis of bioinformatics analysis.In addition,the pathogenicity of the novel APPL1 variant was preliminarily evaluated through in vitro functional experiments.Finally,the impact of these variants on APPL1 protein expression and the insulin pathway were assessed,and the potential mechanism underlying the interaction between the APPL1 protein and the insulin receptor was further explored.RESULTS A total of five novel mutations were identified,including four missense mutations(Asp632Tyr,Arg633His,Arg532Gln,and Ile642Met)and one intronic mutation(1153-16A>T).Pathogenicity prediction analysis revealed that the Arg532Gln was pathogenic across all predictions.The Asp632Tyr and Arg633His variants also had pathogenicity based on MutationTaster.In addition,multiple alignment of amino acid sequences showed that the Arg532Gln,Asp632Tyr,and Arg633His variants were conserved across different species.Moreover,in in vitro functional experiments,both the c.1894G>T(at Asp632Tyr)and c.1595G>A(at Arg532Gln)mutations were found to downregulate the expression of APPL1 on both protein and mRNA levels,indicating their pathogenic nature.Therefore,based on the patient’s clinical and family history,combined with the results from bioinformatics analysis and functional experiment,the c.1894G>T(at Asp632Tyr)and c.1595G>A(at Arg532Gln)mutations were classified as pathogenic mutations.Importantly,all these mutations were located within the phosphotyrosinebinding domain of APPL1,which plays a critical role in the insulin sensitization effect.CONCLUSION This study provided new insights into the pathogenicity of APPL1 gene mutations in diabetes and revealed a potential target for the diagnosis and treatment of the disease. 展开更多

Microbial components and the endogenous molecules released from damaged cells can stimulate germ-line-encoded pattern recognition receptors(PRRs)to transduce signals to the hub of the innate immune signaling network-the adaptor proteins MyD88/TRIF/MAVS/STING/Caspase-1,where integrated signals relay to the relevant transcription factors IRF3/IRF7/NF-κB/AP-1 and the signal transducer and activator of tran-scription 6(STAT6)to trigger the expression of typeІinterferons and inflammatory cytokines or the assem-bly of inflammasomes.Most pleiotropic cytokines are secreted and bind to specific receptors,activating the signaling pathways including JAK-STAT for the prolif-eration,differentiation and functional capacity of im-mune cells.This review focuses on several critical adaptors in innate immune signaling cascades and recent progress in their molecular mechanisms. 展开更多

Suppression mechanisms mediated by transcriptional repressors commonly exist in diverse phytohormone signaling pathways.In Arabidopsis thaliana,JASMONATE-ZIM DOMAIN(JAZ)proteins are transcriptional repressors that function as negative regulators of diverse JA responses.Novel Interactor of JAZ(NINJA)is an adaptor protein connecting JAZs with the co-repressor,TOPLESS(TPL),to mediate gene repression in JA-dependent root growth inhibition and defense pathways.However,whether NINJA or other adaptor proteins are employed in other JA-responsive biological processes remains to be elucidated.In the present study,we demonstrate that a previously uncharacterized protein,ECAP(EAR motif-Containing Adaptor Protein),directly interacts with JAZ6 and JAZ8 and enhances their transcriptional repression activities.We provide evidence that ECAP is a novel adaptor protein for JAZ6/8 recruitment of the transcriptional co-repressor,TOPLESS-RELATED 2(TPR2),into a transcriptional repressor complex that represses the WD-repeat/bHLH/MYB complex,an important transcriptional activator in the JA-dependent anthocyanin biosynthesis pathway.Our findings,together with previous reports,reveal that specific adaptor proteins play a critical role in distinct JA responses by pairing different JAZs(which possess overlapping but also specific functions)with the general co-repressors,TPL and TPRs. 展开更多

OBJECTIVE:To examine the efficacy of Qinghuayin(清化饮,QHY)in rat chronic atrophic gastritis(CAG)models and explored the molecular mechanism of QHY in treating CAG.METHODS:In total,65 Wistar rats were randomly divided into the control(n=10)and CAG groups(n=55).CAG model rats were further divided into five groups:model(n=10),vitacoenzyme(n=10),low-dose QHY(n=10),medium-dose QHY(n=10),and high-dose QHY groups(n=10).We analyzed histopathological changes using hematoxylin and eosin staining and measured interleukin(IL)-6 and IL-8 levels in serum using enzyme-linked immunosorbent assay(ELISA)(Boster Bio,Pleasanton,USA).In addition,gastrin(GAS),pepsinogen I(PGI),and PGII expressions were evaluated using ELISA.The protein and m RNA expression of toll-like receptor 4(TLR4)and toll or interleukin-1 receptor domaincontaining adaptor inducing interferon-β(TRIF)was detected by Western blotting and quantitative reverse transcription-polymerase chain reaction,respectively.RESULTS:Our results revealed that histopathological changes in CAG model rates could be restored by low-,medium-,and high-dose QHY.The changes in GAS and PGI/II expression demonstrated that QHY improved CAG.Serum IL-6 and IL-levels were decreased by QHY administration.TLR4 and TRIF were upregulated at the m RNA and protein levels in the model group but downregulated by QHY administration.CONCLUSION:We concluded that QHY could effectively improve the histopathological changes of the gastric mucosa induced by CAG in rats.The therapeutic mechanism of QHY may be related to inhibition of the inflammatory factors IL-6 and IL-8 and suppression of TLR4/TRIF m RNA and protein expression. 展开更多
