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

The midcycle luteinizing hormone (LH) surge triggers several tightly linked ovarian processes, including steroidogenesis, oocyte maturation, and ovulation. We designed studies to determine whether epidermal growth factor receptor (EGFR)-mediated signaling might serve as a common regulator of these activities. Our results showed that EGF promoted steroidogenesis in two different in vitro models of oocyte-granulosa cell complexes. Inhibition of the EGFR kinase prevented EGF-induced steroidogenesis in these in vitro systems and blocked LH-induced steroidogenesis in intact follicles primed with pregnant mare serum gonadotropin. Similarly, inhibition of the EGFR kinase attenuated LH-induced steroidogenesis in MA-10 Leydig cells. Together, these results indicate that EGFR signaling is critical for normal gonadotropin-induced steroidogenesis in both male and female gonads. Interestingly, inhibition of metalloproteinase-mediated cleavage of membrane-bound EGF moieties abrogated LH-induced steroidogenesis in ovarian follicles but not MA-10 cells, suggesting that LH receptor signaling activates the EGFR by different mechanisms in these two models. Finally, steroids promoted oocyte maturation in several ovarian follicle models, doing so by signaling through classical steroid receptors. We present a model whereby steroid production may serve as one of many integrated signals triggered by EGFR signaling to promote oocyte maturation in gonadotropin-stimulated follicles.
