1 · What the graph read from it

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.

2 · The registry

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

Proper maintenance of plasma membrane (PM) cholesterol is essential for diverse processes ranging from animal development to pathogen evasion. Despite decades of study, the mechanisms governing cellular cholesterol regulation are incomplete. Using genome-wide screens we find that ACC1, the rate-limiting enzyme in fatty acid biosynthesis, regulates PM cholesterol transport. ACC1 loss causes a ~10-fold increase in PM accessible cholesterol in cells and mice. Mechanistically, we find that ACC1 regulates lipid droplet (LD) catabolism, and LDs are intimately tied to PM accessible cholesterol levels since reductions or elevations in their numbers block or promote cholesterol trafficking, respectively. Furthermore, LDs are required for cholesterol trafficking induced by 25-hydroxycholesterol, a modulator of inflammation and an interferon-stimulated second messenger that protects cells from pathogen invasion. This work identifies an unrecognized role for ACC1 and LDs in cholesterol regulation, which has implications for diseases where LD numbers are altered, from metabolic syndromes to neurodegeneration.
