dc.description.abstract | Diacylglycerol (DAG) is an intermediate lipid involved in the synthesis of phospholipids and triglycerides. As signaling regulators, DAG activate novel protein kinase C leading to decreased response to insulin in skeletal muscle. Alteration of DAG contents correlates with development of metabolic dysregulation in obese and diabetic conditions. Recent advances in lipidomics using mass spectrometry allow expanded measurements of various lipid species. This study describes a rapid measurement of DAG species using the triple quadrupole mass spectrometry using atmospheric pressure chemical ionization in a positive ion mode. DAG in the cells and muscle tissues were separated depending on differences in chain lengths and degree of unsaturation. The limit of detection and quantification for DAG was 0.2 to 17 pmol for this method. When C2C12 cells were treated with palmitate or oleate, we found a 12-fold and 2-fold DAG increase respectively compared to the no-treatment control. In the muscles of obese db/db mice, DAG levels were elevated by 6-fold compared to those of wild-type skeletal muscles. The present analytical method provides a rapid and sensitive quantification of DAG molecular species from various biological samples and can be used to correlate the degree of metabolic dysregulation with lipotoxic metabolites. | - |
