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

Spinal muscular atrophy (SMA), the leading genetic disorder of infant mortality, is caused by low levels of survival motor neuron (SMN) protein. Currently it is not clear how the SMN protein levels are regulated at the post-transcriptional level. In this report, we find that Usp9x, a deubiquitinating enzyme, stably associates with the SMN complex via directly interacting with SMN. Usp9x deubiquitinates SMN that is mostly mono- and di-ubiquitinated. Knockdown of Usp9x promotes SMN degradation and reduces the protein levels of SMN and the SMN complex in cultured mammalian cells. Interestingly, Usp9x does not deubiquitinate nuclear SMNΔ7, the main protein product of the SMN2 gene, which is polyubiquitinated and rapidly degraded by the proteasome. Together, our results indicate that SMN and SMNΔ7 are differently ubiquitinated; Usp9x plays an important role in stabilizing SMN and the SMN complex, likely via antagonizing Ub-dependent SMN degradation.
