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

Previous work from our laboratory has shown that primary fibroblasts from long-lived Snell dwarf mice display a higher sensitivity to the lethal effects of endoplasmic reticulum (ER) stressors, such as thapsigargin, than cells from normal mice. Here we show that thapsigargin induces higher expression of CHOP, enhanced cleavage of caspase-12, higher caspase-3 activity, and increased phosphorylation of c-JUN, all indicators of enhanced apoptosis, in dwarf fibroblasts. Dwarf and normal fibroblasts show no genotypic difference in up-regulating BiP, GRP94, and ERp72 proteins after exposure to thapsigargin. However, dwarf fibroblasts express lower basal levels of a number of putative XBP1 target genes including Armet, Edem1, Erdj3, p58(IPK) and Sec61a1, as well as Ire1α itself. Furthermore, when exposed to thapsigargin, dwarf fibroblasts display attenuated splicing of Xbp1, but similar phosphorylation of eIF2α, in comparison to normal fibroblasts. These data support the notion that IRE1/XBP1 signaling is set at a lower level in dwarf fibroblasts. Diminished Xbp1 splicing in dwarf-derived fibroblasts may tilt the balance between prosurvival and proapoptotic signals in favor of apoptosis, thereby leading to higher induction of proapoptotic signals in these cells and ultimately their increased sensitivity to ER stressors. These results, together with recent findings in Caenorhabditis elegans daf-2 mutants, point to a potential interplay between insulin/IGF-1 signals and unfolded protein response signaling.
