Objective To investigate the roles of SENP1 in regulation of biological characteristics of NK cells.Methods Lentivirus-mediated-Senp1-small-hairpinRNA (shRNA) transduction was applied to NK92 cells.The expression of SENP1 in NK92 cells was determined by real-time PCR and Western blot.The proliferation of NK92 cells was detected by CCK-8 assay.The apoptosis of NK92 cells was determined by Annexin Ⅴ and PI labeling.The cytotoxicity of NK92 cells against K562 cells was evaluated by luciferase reporter assay.Results Treatment of NK92 cells with IL-21 resulted in SENP1 upregulation.Lentivirus mediated SENP1 knockdown reduced proliferation and increased apoptosis in NK-92 cells,but SENP1 inhibition had slight impact on the cytotoxic ability of NK92 cells to kill K562 cells.Conclusion SENP1 mediates the regulatory effect of IL-21 on the proliferation and survival of NK92 cells.

Objective To construct a prostate cancer specific oncolytic adenovirus armed with a fusion protein gene , PSA-IZ-CD40L, and to evaluate its oncolytic efficiency and immune activation ability in vitro.Methods Prostate Specific Antigen (PSA) gene, CD40L-N and CD40L-C genes were obtained from cDNA of LNCaP cells and Jurkat cells using poly-merase chain reaction (PCR) or nested-PCR, respectively.PSA,Linker,CD40L-N and CD40L-C were linked sequentially to generate fusion protein gene PSA-IZ-CD40L (PL) by overlapping PCR.Then, prostate specific oncolytic adenovirus PL-carrying gene, Ad-PL-PPT-E1A,was constructed using the oncolytic adenovirus system , which was based on Adeasy sys-tem.PC3M cells were infected by Ad-PL-PPT-E1A at serial multiplicity of infection (MOI), and the apoptosis was detec-ted by flow cytometry at several time points post-infection.For immune activation detection , PC3M cells were infected with Ad-PL-PPT-E1A at a MOI of 50, and the cell lysate was collected at 48 h post-infection.Peripheral blood mononuclear cells derived (PBMCs) from healthy donors were stimulated by the lysate from PC 3M cells or Ad-PL-PPT-E1A infected PC3M cells before proliferation was assayed using cell counting kit-8 (CCK8).Results Fusion protein gene, PSA-IZ-CD40L, was successfully constructed and cloned into the prostate cancer specific adenovirus to generate Ad -PL-PPT-PL. The expression of E1A and PL protein could be detected by reverse transcription PCR and Western-blotting.Cytopathic effect was observed in PC3M cells infected with Ad-PL-PPT-E1A.Furthermore, the apoptosis rate reached 70.67% ± 2.98%at 48 h post-infection with 200 MOI Ad-PL-PPT-E1A.Compared with the lysate of PC3M cells, that from Ad-PL-PPT-E1A infected cells could promote the proliferation of PBMCs .Conclusion We have constructed a prostate cancer spe-cific oncolytic adenovirus armed can fusion protein gene PL , Ad-PL-PPT-E1A, which could kill PC3M cells effectively and enhance the proliferation of PBMCs in vitro.

Objective To study the role of endothelial cells on the inflammatory cytokine release in septic shock through the septic shock serum stimulating human primary endothelial cells (HPAEC) and peripheral blood mononuclear cells(PBMC).Methods PBMC isolated from healthy people by density gradient centrifugation.HPAEC cell surface markers CD144 and von Willebrand factor(vWF) molecule expression by RT-PCR and Western blot.Serum levels of IL-6,TNF-α,MCP-1 from septic shock patients and healthy human detected by ELISA.HPAEC and PBMC were stimulated with the isolated serums and LPS,respectively.ELISA was used to detect the supernatant IL-6,TNF-α,MCP-1 levels.HPAEC membrane molecules ICAM-1 expression was detected by flow cytometry with serum shock and LPS stimulation.Supernatant levels of IL-6,TNF-α,MCP-1 of HPAEC with S1P1 receptor agonist CYM-5442 pretreatment was detected by ELISA after shock serum stimulation.Results Endothelial cell markers CD144 and vWF molecules could be detected in the HPAEC.Levels of inflammatory cytokines IL-6,TNF-α,MCP-1 in patients with septic shock serum were significantly higher than healthy people (P<0.01).PBMC and HPAEC with LPS or shock serum treatment respectively,compared with normal group,levels of inflammatory cytokines in the culture supernatant were significantly higher(P<0.01).For PBMC,the level of inflammatory cytokines between shock group and LPS group were not significantly different (P>0.05).But for HPAEC,levels of inflammatory cytokines in the supernatant of the shock group compared to the LPS group was significantly higher (P<0.01).Similarly,when two cells after LPS stimulation,IL-6,TNF-α levels of HPAEC's supernatant were significantly lower than PBMC' s (P<0.01),MCP-1 levels was no difference (P> 0.05).But when the stimulation of shock serum,HPAEC of IL-6,TNF-α levels and PBMC no significant difference (P >0.05).MCP-1 was significantly increased (P<0.01).Shock patients serum stimulation S1P1 receptorspecific agonist CYM-5442 pretreatment of HPAEC with pretreatment of S1P1 receptor specific agonist CYM-5442,the culture supernatant of inflammatory cytokines IL-6,TNF-α,MCP-1 levels were significantly lower (P<0.01).Conclusion Endothelial cells may play a central role on the release of inflammatory cytokine during septic shock.
