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

Changes in the intracellular concentration of free calcium ([Ca(2+)]i) regulate diverse cellular processes including fertilization. In mammalian eggs, the [Ca(2+)]i changes induced by the sperm unfold in a pattern of periodical rises, also known as [Ca(2+)]i oscillations. The source of Ca(2+) during oscillations is the endoplasmic reticulum ([Ca(2+)]ER), but it is presently unknown how [Ca(2+)]ER is regulated. Here, we show using mouse eggs that [Ca(2+)]i oscillations induced by a variety of agonists, including PLCζ, SrCl2 and thimerosal, provoke simultaneous but opposite changes in [Ca(2+)]ER and cause differential effects on the refilling and overall load of [Ca(2+)]ER. We also found that Ca(2+) influx is required to refill [Ca(2+)]ER, because the loss of [Ca(2+)]ER was accelerated in medium devoid of Ca(2+). Pharmacological inactivation of the function of the mitochondria and of the Ca(2+)-ATPase pumps PMCA and SERCA altered the pattern of oscillations and abruptly reduced [Ca(2+)]ER, especially after inactivation of mitochondria and SERCA functions. We also examined the expression of SERCA2b protein and found that it was expressed throughout oocyte maturation and attained a conspicuous cortical cluster organization in mature eggs. We show that its overexpression reduces the duration of inositol-1,4,5-trisphosphate-induced [Ca(2+)]i rises, promotes initiation of oscillations and enhances refilling of [Ca(2+)]ER. Collectively, our results provide novel insights on the regulation of [Ca(2+)]ER oscillations, which underlie the unique Ca(2+)-signalling system that activates the developmental program in mammalian eggs.
