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 TSC complex formed by TSC1 and TSC2 is the most important upstream negative regulator of mTORC1. Genetic variations in either TSC1 or TSC2 cause tuberous sclerosis complex (TSC) disease which is a rare autosomal dominant disorder resulting in impairment of multiple organ systems. In this study, besides a reported variation, c.2509_2512del (p.Asn837Valfs*11, p.N837fs) in TSC1, we found a de novo TSC2 variation c.1113delG (p.Gln371Hisfs*18, p.Q371fs), which these two mutation influence the formation of TSC complex. We found that the decrease of TSC complex with the appearance of the decreased miR-199b-3p expression. At the same time, the reduction of miR-199b-3p increased the expression of mTOR and the activation of mTORC1 and mTORC2, the additional miR-199b-3p caused the decrease the expression of mTOR and the activation of mTORC1 and mTORC2. In brief, our results may illustrate a novel mechanism of TSC caused by variations in either TSC1 or TSC2, and a new mTOR expression regulator, miR-199b-3p.
