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

Inhibitor of differentiation (Id) proteins act during embryogenesis and development to repress gene transcription required for lineage commitment, while promoting cell growth. Growth factors belonging to the TGFbeta superfamily of signaling molecules, notably the bone morphogenetic proteins (BMPs) and activin, can regulate Id expression in these tissues. Id expression and function in adult physiology is less well determined, and we hypothesized a role for Id proteins in the adult mammalian ovary. Immunohistochemistry for Id1, Id2, Id3, and Id4 in the sheep ovary revealed consistent expression in granulosa and thecal cells of ovarian follicles throughout development. In atretic follicles, Id proteins were selectively down-regulated in thecal cells (P < 0.0001). Additionally, Id1 was universally up-regulated in the cumulus cells adjacent to the oocyte. Immunohistochemistry for phospho (p)-smad 1/5/8 signaling components (stimulated by BMPs) showed a punctate pattern of expression whereas p-smad 2/3 (stimulated by activin) was ubiquitously expressed in follicles. Neither pathway, however, displayed differential staining in line with Id1 cumulus-specific expression, suggesting a more complex relationship between Id1 expression and TGFbeta signaling in these cells. Nevertheless, in vitro, stimulation of ovine granulosa cells with BMP6 or activin A led to a respective increase and decrease in Id1 (P < 0.0001), Id2 (P < 0.0001), Id3 (P < 0.0001), and Id4 (P < 0.05) transcripts, and Id1 gene expression was further manipulated by the oocyte-secreted factors BMP15 and growth differentiation factor 9 (P < 0.001). These data confirm that TGFbeta signaling can regulate Id gene expression in the sheep ovarian follicle and suggest a functional role for the Id family in the mammalian ovary.
