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

Lipid synthesis plays a central role in cell structure, signaling, and metabolism. A general method for the abiogenesis of natural lipids could transform the development of lifelike artificial cells and unlock new ways to explore lipid functions in living cells. Here, we demonstrate the abiotic formation of natural lipids in water using visible-light-driven photoredox chemistry. Radical-mediated coupling of hydrocarbon tails to polar single-chain precursors yields lipids identical to those enzymatically formed. Spatiotemporally controlled lipid generation promotes de novo vesicle formation, growth, and division. Lipid synthesis can be driven by RNA aptamers that specifically bind and activate photocatalysts, establishing a direct link between abiotic lipid metabolism and nucleic acid sequence. Light-mediated assembly of bioactive lipids can take place in living cells, triggering signaling events such as apoptosis and protein kinase C (PKC) activation. Our finding that photochemical lipid synthesis can be driven by simple genetic elements could be the starting point for developing protocells capable of Darwinian evolution. Additionally, the ability to generate specific membrane lipids in living cells with precise spatiotemporal control will advance studies on how lipid structure influences cellular function.
