| 1 | Identification,structure and function of a novel tetraspaninhoniologue from Spirometra erinaceieuropaei显示文摘Objective:To identify a full length cDNA sequence of a novel tetraspanin(TSP) homologue from Spirometra erinaceieuropaei and to predict the structure and function of its encoding protein using bioinformatics methods.Methods:Using the NCBI,EMBI,Expasy and other online sites, the open reading frame(ORF),conserved domain,physical and chemical parameters,signal peptide,transmembrane domain,epitope,topological structures of the protein sequences were predicted.And Vector NTI software was used for multiple sequence alignment and phylogenetic tree construction.Results:’Hie target sequence was 1 132 hp length with a 681 hp biggest ORF encoding 226 amino acids protein with typical TSP conserved domain.It was confirmed as full length cDNA of TSP16 from Spirometra erinaceieuropaei and named as SeTSP16 (GenBank accession number:JF728872).The predicted molecular weight and isoelectric point of the deduced protein were 24 750.5 Da and 7.88 Da,respectively.Compared with TSP16s from Schistosoma japonicum and Schistosoma mansoni.it showed similarity of 59%and 59%, respectively.SeTSP16 contained four transmembrane domains(TM 1-4),intracellular N and C-termini,one short small extracellular loop and one large extracellular loop.Four major epitopes that were significant different from the corresponding epitope regions of TSP16 from Schistosoma mansoni and Schistosoma japonicum were predicted.Conclusions:The full length cDNA sequences of SeTSP16 arc identified.It encodes a transmembrane protein which might be an ideal diagnosis antigen and target molecule for antiparasitic drugs. | Fu Qiongyao Lu Yajun Rao Langyu Chen Jinglong Wu Qiang Cai Qunfang Li Lihua Wu Lixian Lu Gang | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，9： | 1 |
| 2 | Reduced Sp1 expression inhibits the proliferation and migration of HepG2 cells显示文摘Specificity protein 1(Sp1)is a ubiquitously expressed transcription factor involved in the regulation of a large number of genes including housekeeping genes as well as actively regulated genes.Increasing evidences have indicated that Sp1 is closely correlated with the occurrence and progression of many tumors.The plasmid expression vector of short hairpin RNA(shRNA)targeting Sp1 was constructed and transfected into HepG2 cells by Lipo2000 transfection reagent.Immunocytochemistry,Western blot and quantitative real-time PCR were applied to determine Sp1 expression,and MTT and Transwell assay were used to analyze the cell proliferation and migration,respectively.The expressions of Sp1 protein and mRNA decreased significantly in HepG2 cell after transfection with Sp1 shRNA,and reduced Sp1 expression inhibited proliferation and migration of HepG2 cells. | Lan Yonghong Rao Langyu Cui Zhigang Niu Haiyan Qi Yaling Yang Zhi | 2021 | 解剖学杂志2021，44，S01： | 0 |
