Surg Nowadays 2012, 42:313?27.The klotho gene was amplified from a cDNA library established from GES-1 cells. The open read frame (ORF) of klotho cDNA sequence was amplified by a forward primer containing Bgl II sequence (italic): ACTCAGAT CTGAGCCGGGCGACGGCGCGCAGA and reverse primer containing a BamHI web-site (italic): CGGTGGATCC CCTATTTGTAACTTCTTCTGCC. The amplified klotho ORF was then cloned into pZsGreen1-C1 vector at Bgl II/ Bam HI web sites (Clontech, Mountain View, USA). The klotho ORF was fused with GFP in the C-terminal of GFP. The pZsGreen1-C1 vector with no insertion was applied as a blank vector handle.ImmunofluorescenceTo recognize the location and expression of LC3-II protein, we performed immunofluorescent staining in GC-7901 cells. Briefly, cells in 24-well plates had been fixed by ten paraformaldehyde for 30 min at four . Just after cells were rinsed with PBS for 3 ?5 min, they have been permeabilized with 0.five Triton X-100 for 15 min. Soon after a light rinse with PBS for three times, cells were incubated with 10 mM citrate buffer (pH three.0) for antigen retrieval for 30 min after which incubated with ten goat serum for 1 h to block nonspecific staining. Subsequently, the cells had been incubated with rabbit-anti-LC3-II antibody (Cell Signaling Technologies, Danvers, MA, USA) overnight at 4 . Soon after washing cells with PBST (PBS plus 0.05 Tween-20) for three ?five min, cells had been continually incubated with goat-anti-rabbit, FITC conjugated antibody (1:600, Cell Signaling Technology) for 1 h at area temperature, after which cells had been washed withXie et al.
