Following on in silico and in vitro work, the effect of MCAD deficiency on CoA metabolism was investigated. Using a recently published HILIC-MS/MS method, free and acylated CoA species could be measured simultaneously in HepG2 MCAD-KO cells. The levels of CoA biosynthesis intermediates and total CoA was also characterised by HPLC in liver samples from MCAD-KO mice exposed to energetic stress (fasting adn cold). qPCR was applied to investigate changes in the CoA metabolism that might constitute ...

The behaviour of a published MCAD-KO HepG2 cell line was compared to that of a wild-type HepG2 cell line in terms of the changes in acyl-CoA and acylcarnitine levels (measured by HILIC-MS/MS) and gene expression pertaining to CoA metabolism (characterised by qPCR). Additionally, the incorporation of label from stable isotope-labelled pantothenate (vitamine B5) was over 24 hours of exposure to an energetic stressor was also investigated.

MCAD-KO mice (C57BL/6J background) were exposed to three different conditions: "fed", "fasting", and "fasting + cold". In this study we determined the concentration of various CoA biosynthetic intermediates (including CoA) and the expression of CoA metabolic genes in liver tissue samples from these groups of mice.
