No significant changes were observed for the expression of ACSL1, DGAT1 or ACDVL. Because obesity is related to chronic low grade inflammation, we also analysed PBMC mRNA expression of the proinflammatory genes IL6 and TNF-alpha, which was not different between the NW and OW-OB groups. Here, DGAT1 is linked to obesity due to melanocortin 4 receptor deficiency.
