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 mammalian cellular prion protein (PrP(C) ) is a highly conserved glycoprotein that may undergo conversion into a conformationally altered isoform (scrapie prion protein or PrP(Sc) ), widely believed to be the pathogenic agent of transmissible spongiform encephalopathies (TSEs). Although much is known about PrP(Sc) conversion and its role in TSEs, the normal function of PrP(C) has not been elucidated. In adult mammals, PrP(C) is most abundant in the central nervous tissue, with intermediate levels in the intestine and heart, and lower levels in the pancreas and liver. PrP(C) is expressed during neurogenesis throughout development, and it has recently been proposed that PrP(C) participates in neural cell differentiation during embryogenesis. In order to establish the developmental timing and to address the cell-specific expression of PrP(C) during mammalian development, we examined PrP(C) expression in bovine gametes and embryos through gestation Day 39. Our data revealed differential levels of Prnp mRNA at Days 4 and 18 in pre-attachment embryos. PrP(C) was detected in the developing central and peripheral nervous systems in Day-27, 32-, and -39 embryos. PrP(C) was particularly expressed in differentiated neural cells located in the marginal regions of the central nervous system, but was absent from mitotically active, periventricular areas. Moreover, a PrP(C) cell-specific pattern of expression was detected in non-nervous tissues, including liver and mesonephros, during these stages. The potential participation of PrP(C) in neural cell differentiation is supported by its specific expression in differentiated states of neurogenesis.
