“…Furthermore, the changes in mRNA levels occur more slowly than the changes in LPL activity 65 . After a 16‐hour fasting, LPL activity in guinea pig adipose tissue was found to be decreased by 80%, while LPL mass dropped only by 30%, 50 implying that posttranscriptional mechanisms are involved. In contrast, the increase of heart LPL activity during fasting occurred without any change in LPL mRNA nor in the rate of LPL synthesis, suggesting that in the heart other mechanisms are involved in the modulation of functional LPL activity 49…”
