Hypoxia preconditioning improves structure and function of astrocytes mitochondria via PGC-1α/HIF signal.

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.
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 protective effect of astrocytes on nerves was demonstrated by mitochondrial transfer. The neuroprotective effect of hypoxic pretreatment is widely accepted. The aim of this research is to investigate the role of hypoxic preconditioning on astrocytes mitochondria. Rat neuronal cells and astrocytes were isolated and cultured. A hypoxic preconditioned astrocyte and oxygen glucose deprivation (OGD) neuronal cell co-culture experiment was used to detect the effect of hypoxic preconditioning (HP) on nerve damage. The silencing of proliferatoractivated receptor γ coactivator-1α (PGC-1α) with siRNA was used to explore the role of HP in the repair of nerve damage and biogenesis of mitochondria. HP increased astrocyte viability and promoted neuroprotective factor secretion. The expression levels of antioxidant enzymes, PGC-1α and uncoupling protein2 (UCP2) were up-regulated by HP. In addition, HP improved mitochondrial function and reduced oxidative stress induced by OGD. It was found that HP astrocytes had a greater neuroprotective effect than normal astrocytes cells. Neuronal apoptosis and reactive oxygen species levels were down-regulated by cell co-culture. The PGC-1α siRNA experiment showed that hypoxia treatment promotes mitochondrial biogenesis and plays a neuroprotective role. HP significantly enhanced the efficacy of astrocytes in the treatment of neuronal injury.
