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

Placental enlargement in somatic cell nuclear transfer-derived mice is attributed to biallelic expression of noncanonical (H3K27me3-dependent) imprinted genes owing to loss of imprinting (LOI). Here, we investigated whether a similar mechanism underlies placental enlargement in intersubspecific hybrids between BDF1 (Mus musculus domesticus) and HMI (M. m. castaneus) mice. Quantitative and allelic expression analyses revealed gene-specific LOI in (BDF1 × HMI)F1 placentas: Jade1 (Phf17) and Slc38a4 showed LOI in all placentas regardless of expression levels, whereas Gab1 and Sfmbt2 exhibited LOI only when expression levels were elevated. Notably, Jade1 and Slc38a4 also showed biallelic expression at lower levels in normal-sized (BDF1 × JF1 [M. m. molossinus])F1 placentas. Maternal knockout of Jade1, Slc38a4, Sfmbt2, or the Sfmbt2 miRNA cluster restored monoallelic expression and significantly reduced the weight of (BDF1 × HMI)F1 placentas, indicating that these genes were collectively responsible for placental enlargement in intersubspecific hybrid placentas. Transcriptomic analysis revealed that LOI of noncanonical imprinted genes occurred after implantation. These findings suggest that placental enlargement in (BDF1 × HMI)F1 hybrids is driven by overexpression of multiple noncanonical imprinted genes, resulting from LOI after implantation and additional hybrid-specific, yet unidentified, upregulation mechanisms.
