The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

Restrictive changes of TCR Vp repertoire and clonal expanded T cells could be found in peripheral blood T cells from patients with T-ALL. However, the clonal expanded T cells' property (clonal expansion leukemic cells or leukemia antigen-specific expansion T cells) should be further characterized. It may play a certain role on detection of minimal residual disease and design of anti-leukemia idiotypic vaccine. The dominant utilization of TCR VjJ repertoire could be found in peripheral blood T cells from patients with B-ALL, meanwhile clonal expansive T cells were existed. It may be a feature of the host immune response for leukemia-associated antigen. The clonal expansive tendency of T cells in V021 and VP23 subfamilies was rather obvious, which may be correlated with certain malignant B-cell clone. The CDR3 sequences of monoclonal expansive T cell in T cell strains were different, which was the base of developing DNA vaccine.
T-ALL患者外周血T细胞的TCR Vβ谱系出现限制性改变,均可检测到克隆性增殖T细胞,尚需进一步鉴定其性质(肿瘤性或抗原特异性增殖),对于研究微小残留病变检测和设计抗白血病独特型疫苗均有一定的意义。B-ALL病人外周血T细胞的TCR Vβ谱系呈现优势利用的特点,并存在克隆性增殖的T细胞,这可能是机体对白血病相关抗原产生的特异性免疫反应;Vβ21和Vβ23亚家族T细胞发生克隆增殖改变的趋向性比较明显,可能与B-ALL相关抗原刺激有关。T细胞株中检测到的肿瘤克隆其CDR3序列具有高度的特异性,是构建DNA疫苗的基础。

These results indiacated that tranferring macrophages combinedwith cytokines could be a new adoptive immunotherapy protocol foradvanced cancer,and rTNF used in vivo locally could induce andactivate macrophages to kill tumor cells.Monocytes when activatedunderwent a series of phenotypic and functional changes includingthe expression of IL-2R which may provide an important immunoregu-latory pathway.The presence of lectin-like molecules on thesurface of monocytes and tumor cells may bring theeffector/target cells together,thus facilitating the inductionof apoptosis in target cells by triggering the production ofcytolytic factors and the modification of target of targer cell surface anti-gens.(such as HLA-DR).
综合以上结果可以得出以下结论:转输巨噬细胞并结合细胞因子的联合应用是肿瘤继承性免疫中的又一新的、有潜力的方法;抗肿瘤细胞因子rTNF可通过激活巨噬细胞在体内抑制对其不敏感的肿瘤细胞的生长;人单核细胞在一定条件下激活后,可表达IL-2R,进而一方面增强其自身对IL-2的敏感性,另一方面在体内也具有调节T细胞功能的作用;单核细胞和肿瘤细胞上存在的凝集素类受体可促使两种细胞之间在凝集素介导下相互接近,并诱发单核细胞产生细胞毒因子,以及通过调节靶细胞上表面抗原的表达,促进诱导靶细胞的细胞凋亡。

To prepare the phosphorylated PRAS40 (Ser183) antibody, We chosen 10-amino acid including Ser183 as antigen peptide through antigenicity and hydrophobicity analysis, hinged on keyhole limpet hemocyanin, and used the KLH-peptide to immunize rabbits. After antibody serum titer detection by enzyme linked immunosorbent assay, the antibody was purified with rProtein A sepharose fast flow and dephosphorylated antigen membrane. The antibody titrate reached 1:10 000 after purification and its special property was enhanced with absorption treatment of dephosphorylated antigen membrane. In addition, we used rabbit anti-PRAS40 antibody and the phosphorylated PRAS40 (Ser183) antibody to detect PRAS40 expression in several cell lines, including the normal cells HL7702, HEK293, tumor cells HepG2, A549 and S180. There were no quite difference among these cells; otherwise, we observed the decreased phosphorylation level of Ser183 after amino acid withdrawal treatment.

Can reverse JA-induced migration inhibition JA-treated cells also showed significantly higher adhesion to laminin In conclusion these results indicate a novel anti-tumor role of JA via reducing reorganization of cytoskeleton increasing integrin 3 expression and adhesion ability to inhibit tumor cells migration Furthermore immunofluorescence staining of phalloidin/actin indicated that JA-treated cells exhibited cytoskeleton rearrangement and significant decreases in the number and length of filopodia Activity of Rho-family small GTPases was detected by a GST-pull down assay and showed that GTP-loaded Cdc42 and Rac were decreased in JA-treated cells In the future we hope these findings will be helpful to further understand the mechanisms underlying tumor progression in oral cancer and subsequently improve the cancer prevention and treatment
以抗体阻断integrin ?3可以有效使OC2恢复被JA所抑制的迁移能力。细胞贴附实验指出JA能提高OC-2在laminin环境下的贴附能力。当我们进一步以免疫萤光染色观察细胞,发现在JA处理下的OC-2,其外形、细胞骨架和细胞边缘的filopodia的密度和长度明显减少,利用GST-pull down assay侦测到Cdc42-GTP和Rac-GTP的表现量降低。推论爵床素A可能透过刺激口腔癌细胞大量表现integrin ?3,使细胞贴附能力增加或是透过改变细胞骨架来降低细胞迁移能力。希望本研究对於JA所做的抗癌及抗转移效应评估能提供口腔癌治疗在研发上一些帮助。
