Characteristics of different lipid droplet-mitochondrial contacts patterns during lipid droplet metabolism in T2DM-induced MASLD.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Mitochondrial function is crucial for hepatic lipid metabolism. Current research identifies two types of mitochondria based on their contact with lipid droplets: peridroplet mitochondria (PDM) and cytoplasmic mitochondria (CM). This work aimed to investigate the alterations of CM and PDM in metabolic dysfunction-associated steatotic liver disease (MASLD) induced by spontaneous type-2 diabetes mellitus (T2DM) in db/db mice. It was found that insulin resistance increased both the number and size of lipid droplets in the liver by enhancing the accumulation of free fatty acids, which is accompanied by an increase in contacts with mitochondria. We described the different patterns of tight contacts between small lipid droplets and mitochondria in purified CM and PDM by examining their oxidation states and morphological characteristics. In CM, enhanced fatty acid oxidation resulted in elongated mitochondria that surrounded single small lipid droplets and were responsible for lipid droplet consumption, while in PDM, increased substrates for lipid synthesis promoted lipid droplet expansion with the assistance of the endoplasmic reticulum. These data show the different ways in which mitochondrial contact with lipid droplets could provide new insights for future research on liver lipid metabolism.
