Abstract:
To generate PP2A Cα knockout model in neonatal mouse ventricular myocytes.Male PP2A Cαfl/fl,Cre/- were selectively mated with female PP2A Cαfl/fl,Cre/- mice to obtain abundant offsprings with the same genotype.The neonatal mouse ventricular myocytes were digested by trypsinization and subsequently infected with Cre-adenovirus.The effects of adenovirus infection were observed by fluorescence microscope and identified by western blot analysis.The offsprings in aboundance were obtained by seting up a mating between male and female of PP2A Cαfl/fl,Cre/-mice,as a result,an abundance of neonatal mouse ventricular myocytes with the genotype of PP2A Cαfl/fl,Cre/-were available for Ad-Cre infection.Green fluorescence was observed after GFP labeled Cre-adenovirus(Cre-Ad)infection for 48 h.The expression level of PP2A Cα protein in Cre-Ad infected myocytes was 60%~80% lower than control.The PP2A Cα knockout model in neonatal mouse ventricular myocytes was successfully generated.
