Chaperone-mediated autophagy controls brown adipose tissue thermogenic activity.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Brown adipose tissue (BAT) protects against obesity, diabetes, and cardiovascular disease. During BAT activation, macroautophagy is inhibited, while chaperone-mediated autophagy (CMA) is induced, promoting thermogenic gene expression, adipokine release, oxidative activity, and lipolysis. Aging reduces BAT function and lowers levels of LAMP2A, the rate-limiting CMA component. Pharmacological CMA activation restores BAT activity in aged mice. To explore the CMA's role in BAT, we generated LAMP2A-deficient brown adipocytes and found that CMA regulates proteins essential for thermogenesis and metabolism. Blocking CMA in BAT reduced energy expenditure, raised blood triglycerides, impaired secretion, and led to an increase of thermogenesis repressors. These findings show that CMA is essential for maintaining BAT function, especially during adaptive thermogenesis. By degrading repressors of thermogenesis, CMA supports BAT activity under cold or metabolic stress. This work highlights CMA as a key regulator of BAT plasticity and a promising therapeutic target for treating age-related metabolic disorders.
