Acute dietary methionine restriction triggers cell cycle arrest and reversible growth defects in the neocortex.

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
Methionine is indispensable for cell proliferation, stem cell maintenance, and epigenetic regulation, three processes that are central to embryonic development. Here, we assessed the consequences of short-term dietary methionine restriction (MR) on mouse embryonic organ growth. In comparison with growth of the liver and heart which was unaffected, MR for 5 days led to a severe reduction in neuronal production and neocortex growth. Progenitor cohort labeling revealed a time-dependent sensitivity to MR and cell cycle analysis indicated that progenitors are stalled in S/G2 phases following MR. Unexpectedly, neuronal production was completely rescued at birth when switching the dam back to control diet, uncovering a mechanism of catch-up growth. We used imaging mass cytometry to probe metabolic and epigenetic markers in neural progenitors following MR and during catch-up growth. Altogether, our data uncover a reversible state of quiescence in S/G2 which is metabolically distinct from G0 quiescence and associated with efficient catch-up growth of the neocortex.
