Ventricular septal defect (VSD) is the most common type of congenital heart disease (CHD). The single gene mutations or absences that contribute to VSD development are well established; however, the aim of the present study was to measure gene expression variation between VSDs and normal
fetal myocardial tissue. TWIST1, an important tumor biomarker, is a basic helixloophelix transcription factor that regulates cell proliferation, migration and differentiation in embryonic development and transformed tumor cells. Although growing evidence demonstrates that TWIST1 participates
in a variety of human neoplastic diseases, the role of TWIST1 in VSD has remained elusive. Twentysix VSD fetal myocardial tissue samples and 12 normal samples at matched gestational weeks (2228 weeks) were included in the present study. Using reverse transcription quantitative polymerase
chain reaction (PCR) and realtime PCR, it was demonstrated that TWIST1 mRNA was reduced by almost twofold in the VSD samples compared with the normal samples. Western blot analysis also revealed that TWIST1 expression was decreased by ~threefold (P=0.001) in the VSD samples compared with that
in the normal samples. Of note, five complete ventricular (also called functionally univentricular or single ventricular) septal ageneses were identified among the specimens. For the five complete ventricular septal agenesis samples, similar results to those for other VSD fetal myocardial
tissues were obtained. In conclusion, the results of the present study showed that TWIST1 mRNA and protein levels were reduced in VSDs. The present study was the first, to the best of our knowledge, to report that TWIST1 is not only a tumor biomarker, but may also be involved in the pathogenesis
