| Research Abstract |
The biological effects of gap and adhesion on cardiac morphogenesis have been investigated.
1.Effects of gap and adhesion molecules on the cell proliferation
Connexin43 and N-cadherin suppress the cell proliferation by induction of P21, cell cycle regulator, mediated G2/M arrest.
2.Effects of adhesion molecules on the cardiac morphogenesis
Genetically targeted N-cadherin induces the cardia bifida, the failure of single heart formation. The N-cadherin expression is regulated by GATA-4, cardiogenic factor, establishing the biological role of signaling pathway from GATA-54 to N-cadherin.
3.Identification of novel type of semaphorin to regulate cardiac morphogenesis :
Semaphorin are originally identified as a regulator for neural development. We identified new member of semaphorin family which regulates cardiac morphogenesis.
