Deletion of Mthfd1l causes embryonic lethality and neural tube and craniofacial defects in mice.
Maternal supplementation with folic acid is known to reduce the incidence of neural tube defects (NTDs) by as much as 70%. Despite the strong clinical link between folate and NTDs, the biochemical mechanisms through which folic acid acts during neural tube development remain undefined. The Mthfd1l gene encodes a mitochondrial monofunctional 10-formyl-tetrahydrofolate synthetase, termed MTHFD1L....
متن کاملConditional inactivation of Tgfbr2 in cranial neural crest causes cleft palate and calvaria defects.
Cleft palate and skull malformations represent some of the most frequent congenital birth defects in the human population. Previous studies have shown that TGFbeta signaling regulates the fate of the medial edge epithelium during palatal fusion and postnatal cranial suture closure during skull development. It is not understood, however, what the functional significance of TGFbeta signaling is i...
متن کاملCreating rigidly stabilized fractures for assessing intramembranous ossification, distraction osteogenesis, or healing of critical sized defects.
Assessing modes of skeletal repair is essential for developing therapies to be used clinically to treat fractures. Mechanical stability plays a large role in healing of bone injuries. In the worst-case scenario mechanical instability can lead to delayed or non-union in humans. However, motion can also stimulate the healing process. In fractures that have motion cartilage forms to stabilize the ...
متن کاملSOCS1 Deficiency Causes a Lymphocyte-Dependent Perinatal Lethality
SOCS1 is an SH2-containing protein that is primarily expressed in thymocytes in a cytokine- and T cell receptor-independent manner. SOCS1 deletion causes perinatal lethality with death by 2-3 weeks. During this period thymic changes include a loss of cellularity and a switch from predominantly CD4+ CD8+ to single positive cells. Peripheral T cells express activation antigens and proliferate to ...
متن کاملLoss of microRNAs in neural crest leads to cardiovascular syndromes resembling human congenital heart defects.
OBJECTIVE Congenital heart defects represent the most common human birth defects. Even though the genetic cause of these syndromes has been linked to candidate genes, the underlying molecular mechanisms are still largely unknown. Disturbance of neural crest cell (NCC) migration into the derivatives of the pharyngeal arches and pouches can account for many of the developmental defects. The goal ...
