Abstract:
OBJECTIVETo investigate the efficacy and mechanisms of recombinant adenovirus containing c-FLIPs (cellular FLICE-inhibitory protein short) in inducing antiapoptosis activation of lymphocyte in vitro.
METHODSc-FLIPs gene was cloned from total RNA of lymphocyte with RT-PCR methods, then constructed recombined adenovirus Ad.c-FLIPs by pAdeasy system. H9 cells infected with Ad.c-FLIPs produced antiapoptosis derived from anti-Apo-1 antibody, and those antiapoptosis evaluated with PI stain flow cytometry (FCM) and Hoechst stain.
RESULTSc-FLIPs gene was successfully cloned from lymphocytes and incorporated into recombinant adenovirus Ad.c-FLIPs.After exposure to anti-Apo-1 for 24 h, the apoptosis of H9 cells preconditioned by Ad.c-FLIPs for 24 h as measured by Hochst stain or FCM significantly decreased, compared with non-preconditioned cells, 3.60% +/- 0.21% vs. 48.33% +/- 7.41%, respectively, indicating that Ad.c-FLIPs preconditioning protected H9 cells against apoptosis induced by anti-Apo-1.
CONCLUSIONRecombinant adenovirus Ad.c-FLIPs effectively induced anti-apoptosis activation of lymphocyte.
