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

We investigated the expression of the nuclear-encoded genes controlling the mitochondrial properties in the mouse gastrocnemius muscle to gain insight into the mitochondrial biogenesis that occurs during the muscle degeneration/regeneration induced by freezing. In addition, we tested whether the muscle regeneration is affected by pharmacologically blocking the mitochondrial protein synthesis to elucidate the possible involvement of mitochondrial biogenesis in muscle regeneration. The activity of citrate synthase dramatically increased soon after the initial injury when the myoblasts began to differentiate into myotubes, indicating that mitochondrial biogenesis occurs early during the muscle regeneration. At the same time, the expression of mitochondrial biogenesis-related genes including PGC-1β, PRC, NRF-1, NRF-2, TFAM, mtSSB, fission 1, and Lon protease synchronized with that of the myogenic regulatory genes including MyoD and myogenin. The skeletal muscles forced to regenerate in the presence of chloramphenicol to block the mitochondrial protein synthesis were of poor repair with small myofibers and an increased amount of connective tissue. These results suggest that mitochondrial biogenesis activated early during the muscle regeneration and that mitochondrial biogenesis plays a role in muscle regeneration.
