Assays

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.

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.

The spatio-temporal model that allows investigating the structure of glycogen in three dimensions . The model is based on a stochastic process that simulates the key enzymatic steps. The model is designed to track the position of all glucose units in time together with the activities of the enzymatic reactions.
