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

Neuroactive steroids, like progesterone (P) and its 5alpha-reduced derivatives dihydroprogesterone (DHP) and tetrahydroprogesterone (THP), are involved in the control of Schwann cell proliferation and in the myelinating program of these cells. Here, we demonstrate that in culture of rat Schwann cells, P and its derivatives also increase expression of Sox-10 and Krox-20 (i.e., two transcription factors with a key role in Schwann cell physiology and in their myelinating program). Data obtained by quantitative RT-PCR analysis show that treatment with P, DHP, or THP increases mRNA levels of Krox-20. This stimulatory effect anticipates that exerted by P and DHP on Sox-10 gene expression. Thus, although the effect on Krox-20 occurs after 1 h, that on Sox-10 reaches a peak after 2 h. A similar pattern of effect is also evident on their protein levels. As evaluated by Western blot analysis, Krox-20 is increased after 3 h of treatment with P, DHP, or THP, whereas P or DHP stimulates the expression of Sox-10 after 6 h of exposure. A computer analysis performed on rat and human promoters of these two transcription factors shows that putative P-responsive elements are present in Krox-20 but not in Sox-10. Interestingly, many putative binding sites for Krox-20 are present in the Sox-10 promoter. The observations reported here, together with the concept that P and its derivatives are able to influence directly the expression of myelin proteins, suggest that these neuroactive steroids might coordinate the Schwann cell-myelinating program utilizing different intracellular pathways.
