Abstract:
Objective To construct p66shc gene interfering lentivirus vectors recombination and transfect it to 293T cells ,RNA interfering was carried out to induce p66shc gene silence ,so as to provide basis for further study of the p66shc function .Methods Screening of three RNA targets which were named after p66shc‐shc1 ,p66shc‐shc2 ,p66shc‐shc3 ,cloned into the pLenR‐GPH vec‐tor ,which contained green fluorescent protein(GFP) and transformed into DH5αcells .The positive clone were picked out for right sequencing and transfected to 293T cells with pRsv‐REV ,pMDlg‐pRRE ,pMD2G .The expression of GFP in inverted fluorescence microscope confirmed the virus packaging success .Fluorescence quantitative PCR and Western blot technology were used to investi‐gate the expression of p66shc at the molecular and protein levels ,p66shc‐shc1 target of effective silencing p66shc gene was selected to prepare for subsequent tests .Results The shRNA lentivirus vector was constructed which could express p66shc and was trans‐fected into 293T cells successfully .Fluorescence quantitative PCR and Western blot technology were used to investigate p66shc gene silence by RNA interference .Conclusion The lentivirus RNAi vector of targeted expression p66shc could induce p66shc gene si‐lence at the molecular and protein levels after transfected into 293T cells by RNA interference .
