In addition to its metabolic actions, A-FABP also plays a critical role in the development of atherosclerosis through coordinating macrophage cholesterol trafficking and inflammatory activity [26].
Beyond its classic metabolic actions, insulin is also anti-inflammatory, decreasing activity of pro-inflammatory cytokines, such as TNF-α and IL-6, as well as repressing the transcription factor nuclear factor кB (NFкB) [ 51].
During the last two decades, several studies have shown that beyond cardiovascular and renal properties, natriuretic peptides also exert metabolic actions.
The metabolic actions of GLP-1 were also tested by analyzing forearm glucose disposal during hyperinsulinemia (n = 5).
1, 2 More recently, it has been suggested that natriuretic peptides also have favourable metabolic actions, including improvement of glucose tolerance and reduction in adipocyte growth.
Not only at high doses but also at low doses, glucocorticoid therapy impaired intermediary metabolism by interfering with the metabolic actions of insulin on liver and adipose tissue.
The PI3K/AKT and ERK/MAPK pathways also exert many of their metabolic actions upon activation of the mTOR complexes, more specifically on the mTOR Complex-1 (mTORC1) which drives ATP-consuming cellular processes necessary for cells to grow and proliferate.
However, these hypotheses do not exclude the possibility that secondary MEHP metabolites could also play important roles in the metabolic actions of DEHP by differentially activating hPPARα and mPPARα.
A second way would be to disrupt insulin's metabolic actions within breast cells after insulin attaches to the receptor.
Intriguingly, however, urocortins are also present at high levels in peripheral metabolic tissues, including skeletal muscle [ 11, 12], implying that these 'stress regulators' have local peripheral as well as central metabolic actions.
