Deficiency of Sox7 leads to congenital aortic stenosis via abnormal valve remodeling.

Abnormal valve development is the most common congenital heart malformation. The transcription factor Sox7 plays a critical role in the development of vascular and cardiac septation. However, it remains unclear whether Sox7 is required for heart valve development.

The Screening and Identification of a Dextranase-Secreting Marine Actinmycete sp. K1 and Study of Its Enzymatic Characteristics.

In this study, an actinomycete was isolated from sea mud. The strain K1 was identified as sp. by 16S rDNA.

Vav2 promotes ductus arteriosus anatomic closure via the remodeling of smooth muscle cells by Rac1 activation.

The ductus arteriosus (DA), bridging the aorta and pulmonary artery, immediately starts closing after birth. Remodeling of DA leads to anatomic obstruction to prevent repatency. Several histological changes, especially extracellular matrices (ECMs) deposition and smooth muscle cells (SMCs) migration bring to anatomic closure.

Integrated genomic analysis identifies novel low-frequency -regulatory variant rs2279658 associated with VSD risk in Chinese children.

VSD combined with other cardiac or extracardiac malformations (defined as "complex VSD" by us) is one of the major causes of perinatal morbidity and mortality. Functional non-coding SNPs (-regulatory SNPs) have not been systematically studied in CHDs, including complex VSD. Here we report an exome-wide association analysis using WES data of 60 PA/VSD cases, 20 TOF cases and 100 controls in Chinese children.
