Cardiac outflow tract (OFT) septation is crucial to the formation of the aortic and pulmonary arteries. Defects in the formation of the OFT can result in serious congenital heart defects. Two cell populations, the anterior heart field (AHF) and cardiac neural crest cells (CNCCs), are crucial for OFT development and septation. In this study, we use a series of tissue-specific genetic manipulatio...
During heart development the second heart field (SHF) provides progenitor cells for most cardiomyocytes and expresses the homeodomain factor Nkx2-5. We now show that feedback repression of Bmp2/Smad1 signaling by Nkx2-5 critically regulates SHF proliferation and outflow tract (OFT) morphology. In the cardiac fields of Nkx2-5 mutants, genes controlling cardiac specification (including Bmp2) and ...

The one-way function tree (OFT) scheme proposed by Balenson et. al is widely regarded as an efficient key management solution for multicast communication in large dynamic groups. Following Horng’s claim that the original OFT scheme was vulnerable to a collusion attack, Ku et. al studied the collusion attack on OFT and proposed a solution to prevent the attack. The solution, however, requires to...

The Postn gene encodes protein periostin. During embryonic development, it is highly expressed in the outflow tract (OFT) endocardial cushions of the developing heart, which give rise to several structures of the mature heart including the aortic valve. Periostin was previously implicated in osteoblast differentiation, cancer metastasis, and tooth and bone development, but its role in cardiac O...
