Abstract:
Objective To construct a lentiviral vector carrying rat sirt1 gene and observe the expression of sirt1 in retinal ganglion cell (RGC) of rat.Methods Rat sirt1 cDNA was inserted into pLV5 vector.After identification by sequencing analysis and PCR,the recombinant sirt1expressinglentivirus vector was packaged by cotransfecting 293T cells with packaged plasmid.Then pLV5-sirt1 was used to infect the cultured Sprague-Dawley rat RGC cell in vitro.The expressions of sirt1 protein and mRNA in infected rat RGC were detected by quantitative real-time PCR and Western blot.Results The sirt1 expression vector pLV5 was successful constructed and sequence was proved to be correct.The expression of sirt1 protein and mRNA in RGC was significantly increased than that in cells infected with control lentiviruses (P ＜ 0.05).Conclusion We have successful constructed a sirt1 expression lentivirus vector pLV5-sirt1 and it can increase the expression of sirt1 protein and mRNA in the rat retinal ganglion cells.
