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

Cytoplasmic polyadenylation of specific mRNAs commonly is correlated with their translational activation during development. Here, we focus on links between cytoplasmic polyadenylation, translational activation and the control of meiotic maturation in Xenopus oocytes. We manipulate endogenous c-mos mRNA, which encodes a protein kinase that regulates meiotic maturation. We determined that translational activation of endogenous c-mos mRNA requires a long poly(A) tail per se, rather than the process of polyadenylation. For this, we injected 'prosthetic' poly(A)_synthetic poly(A) tails designed to attach by base pairing to endogenous c-mos mRNA that has had its own polyadenylation signals removed. This prosthetic poly(A) tail activates c-mos translation and restores meiotic maturation in response to progesterone. Thus the role of polyadenylation in activating c-mos mRNA differs from its role in activating certain other mRNAs, for which the act of polyadenylation is required. In the absence of progesterone, prosthetic poly(A) does not stimulate c-mos expression, implying that progesterone acts at additional steps to elevate c-Mos protein. By using a general inhibitor of polyadenylation together with prosthetic poly(A), we demonstrate that these additional steps include polyadenylation of at least one other mRNA, in addition to that of c-mos mRNA. These other mRNAs, encoding regulators of meiotic maturation, act upstream of c-Mos in the meiotic maturation pathway.
