Sensing of Long-Chain Fatty Acyl-CoA Esters by AMPK.
Article in Methods in molecular biology (Clifton, N.J.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fatty acids are utilized to maintain cellular energy/adenine nucleotide balance under times of energetic stress such as during endurance exercise or fasting. It has long been recognized that fatty acids stimulate their own oxidation through a mechanism involving allosteric inhibition of acetyl-CoA carboxylase (ACC) and reductions in malonyl-CoA. We have recently described a parallel pathway by which long-chain fatty acid-CoAs bind to and activate the AMP-activated protein kinase (AMPK) at the allosteric drug and metabolic (ADaM) binding site. Increases in AMPK activity lead to the phosphorylation and inhibition of ACC which is essential for fatty acids to stimulate fatty acid oxidation. Here, we describe the methods to detect fatty acyl-CoA-induced activation of AMPK in cell-free assays, primary mouse hepatocytes, and in the liver of mice. These methodologies will be useful to allow further investigations into the importance of this fatty acid sensing axis in regulating metabolism and provide a framework for future studies investigating whether there may be other natural ligands targeting the ADaM binding site of AMPK.
