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

Selenoprotein P (SelenoP) functions as a plasma transporter of selenium (Se) from liver to other tissues via incorporation into multiple selenocysteine (Sec) residues. Selenocysteine lyase (Scly) is an intracellular enzyme that decomposes Sec into selenide, providing Se for the synthesis of new selenoproteins. Both SelenoP and Scly are mostly produced by the liver. Previous studies demonstrated that male mice lacking SelenoP (SelenoP KO) or Scly (Scly KO) had increased or decreased total hepatic Se, respectively. While SelenoP regulation by Se is well-studied, Scly regulation by Se has not been reported. We hypothesize that Scly is negatively regulated by Se levels, and that absence of SelenoP jeopardizes Scly-dependent Se recycling. Using in vitro and in vivo models, we unveiled a tissue-specific Se regulation of Scly gene expression. We also determined that SelenoP, a considered source of intracellular Se, affects Scly expression and activity in vitro but not in vivo, as in the absence of SelenoP, Scly levels and activity remain normal. We also showed that absence of SelenoP does not increase levels of transsulfuration pathway enzymes, which would result in available selenocompounds being decomposed by the actions of cystathionine γ-lyase (CGL or CTH) and cystathionine β-synthase (CBS). Instead, it affects levels of thioredoxin reductase 1 (Txnrd1), an enzyme that can reduce selenite to selenide to be used in selenoprotein production. This study evaluates a potential interplay between SelenoP and Scly, providing further insights into the regulation of selenium metabolism.
