Abstract:
Objective:To investigate mRNA expression of cardiac related genes of NKX2.5,TBX5 and GATA4 in patients with tetralogy of fallot(TOF). Methods:A total of 10 TOF patients(TOF group)from 4 months to 8 years with the mean age of 3.5 years were recruited in our hospital from June to December 2005.The patients were diagnosed by typical clinical manifestation and cardiac color echocardiogram, the diagnosis was confirmed by cardiac surgery.6 non-congenital heart disease children were selected as Control group, and they were from 4 months to 9 years with the mean age of 3.8 years.The myocardial total RNA was extracted,the related cDNA was obtained by RT-PCR.The product cDNA was amplified with fluorescent quantitative PCR in order to compare the differences of NKX2.5,TBX5,GATA4 and GAPDH mRNA expression between TOF group and Control group. Results:NKX2.5 mRNA expression in TOF group was statistically decreased than that in Control group,while there were no statistical changes found in TBX5 and GATA4 mRNA expression between TOF group and Control group. Conclusion:The mRNA expression of NKX2.5,TBX5 and GATA4 were found in myocardium development.TOF was possibly related to decreased NKX2.5 mRNA expression.
