Abstract:
AIM:To construct myocardium-specific nucleolin ( Ncl) transgenic mice and to provide an animal model for the studies of the myocardial protection of nucleolin .METHODS:To create nucleolin transgenic mice , a myo-cardium-specific expression plasmid of nucleolin ( Alpha-MyHC clone 26-Ncl) was constructed .The gene type of transgenic mice was identified by PCR and the nucleolin protein level was tested by Western blotting .The myocardium morphology , heart weight index (HWI) and left ventricular pressure maximum rise rate were observed in nucleolin transgenic (TG) mice and wild-type ( WT) mice.RESULTS:We gained 4 transgenic mice (51, 52, 56 and 86 lines, only 52 line and 86 line were eugonic) by PCR.Western blotting analysis showed the expression of nucleolin up-regulated specifically in the myocardium .However , the myocardium morphology , HWI and left ventricular pressure maximum rise rate in the nucleolin transgenic mice were similar to those in the wild-type mice.CONCLUSION:We constructed myocardium-specific nucleo-lin transgenic mice successfully .
