• Currently, scientists are investigating AICAR’s therapeutic properties to treat various metabolic disorders through preclinical research and mice trials.
• Our results provide the first direct evidence of the beneficial effects of pharmacological activation of AMPK by AICAR against the progression of PALI, including reduced redox stress and decreased NLRP3 inflammasome activation.
• FAS is an enzyme that is considered to play a crucial role in synthesizing fatty acids.

Our data confirm previous reports showing that AICAR, when incubated with nuclear extracts from murine macrophages, directly interferes with DNA binding of NFκB, CREB and C/EBPβ24. In line, AICAR prevented DNA binding of NFκB and AP-1 in nuclear fractions of endothelial cells33. EMSA experiments conducted in AICAR-treated endothelial or tumour cells also showed decreased NFκB binding34,35, although under these conditions the effects were attributed to AMPK activation.

AICAR also did not affect elevation of PPARγ mRNA expression during monocyte to macrophage differentiation19. At the same time, STAT3 target gene expression was inhibited by AICAR in AMPK-independent fashion. Previously, we showed broad inhibition of transcriptional unfolded protein response (UPR) by AICAR20, suggesting its direct interference with transcriptional UPR effectors, such as activating transcription factor 4 (ATF4), X-box binding protein 1, and ATF6.

From the results, AICAR was suggested to reduce myocardial tissue infarction size and cardiac cell death and apparently improve the overall outcome of the experiment. The study concluded that AICAR may "reduce […] adverse cardiovascular outcomes." AMPK activators have been shown to play an important role in inflammation at the cellular level. Research into metformin, a common and long-used diabetes medication, indicates that at least part of the reason the drug is effective is that it reduces inflammation and boosts the function of the pancreas. AICAR has a similar effects, playing a protective role in inflammatory conditions like acute lung injry, asthma, colitis, atherosclerosis, and hepatitis[8].

Cell isolation and culture

It may also modulate insulin secretion and skeletal muscle fatty acid oxidation with glucose uptake. Several energy deficit states may trigger the release of AMPK, like hypoxia or hypoglycemia. In summary, our data indicate that AICAR, a direct AMPK activator, exhibits significant therapeutic effects against PALI in sodium taurocholate- and L-arginine-induced rodent models by promoting AMPK phosphorylation by effectively inhibiting hepatic oxidative stress and inflammation. Thus, as a cell permeable nucleoside, AICAR has high therapeutic value for the treatment of PALI. Importantly, this study provides new insight into the mechanisms underlying the improvement of hepatic oxidative stress and inflammation in PALI by AICAR.

Thus, this inactivation could potentially lead to a decrease in fatty acid synthesis and an apparent increase in fatty acid oxidation to fuel the cells with energy. To explain the broad effect of AICAR on transcriptional activation we considered the interaction with general component of the transcription machinery. However, this is unlikely to be the case, since STAT6-dependent and HIF-evoked gene expression remained unaltered in AICAR-treated cells.

One study investigated the potential of AICAR, an AMPK activator, on an experimental murine model of ethanol-induced hepatic steatosis.(4) The study observed that chronic ethanol exposure appeared to result in a histologically and biochemically fatty liver. Upon AICAR presentation, it appeared to attenuate the degree of change in the liver tissues. AICAR was also posited to decrease the hepatic sterol regulatory element-binding protein 1c (SREBP-1c) and reduce fatty acid synthase (FAS) enzyme expression, reducing triglyceride synthesis in murine models’ livers.
