Abstract

Metabonomic analysis has been increasingly used to monitor metabolic abnormalities in cells and their micro-environment in order to detect the biomarkers recently. This study evaluated the feasibility of applying 1H-nuclear magnetic resonance (1H-NMR) based metabonomic method to detect the differences of the early development of cleft palate in the plasma from control group and experimental group. Pregnant mice (inbred C57BL/6J strain) with vitamin B12 injected only were assigned as the control group, pregnant mice with excessive Dex, injected after vitamin B12 as the experimental group, each group includes 12 mice. And the effect of B12 to rate of cleft palate was observed. The technology of nuclear magnetic resonance (NMR) was used to detect the endogenous small molecule metabolites. Finally, changes of metabolites ingredients were ascertained by using the method of principal component analysis (PCA). There was significant difference in PCA scores plot between the two groups according to whether cleft palate occurred. The 1H-NMR based metabonomic approach might be used as a feasible and efficient method for a deep exploration of the pathogenesis of cleft lip and palate and an early exploration of the mechanism of vitamin B12.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
