Activating transcription factor 4 modulates BDNF release from microglial cells.

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
Pathogenic pain is a common sign of many diseases. The mechanism is unclear. Activating transcription factor 4 (ATF4) plays a critical role in cell activation. Brain-derived neurotrophic factor (BDNF) is an important molecule in pathogenic pain. This study aims to investigate the role of ATF4 in inducing BDNF release from microglial cells. In this study, mouse microglial cells were cultured. The levels of BDNF in the culture medium were determined by enzyme-linked immunosorbent assay. Overexpression of ATF4 in microglial cells was performed by gene transfection. The apoptosis of microglial cells was assessed by flow cytometry. The results showed that microglial cells expressed ATF4 and protease-activated receptor-2 (PAR2). BDNF was detectable in the culture medium of microglial cells, which was significantly increased in the ATF4-overexpressing microglial cells. The ATF4-overexpressing microglial cells showed a high frequency of apoptotic cells, which could be inhibited by exposure to the PAR2 agonist tryptase in the culture. The tryptase-treated ATF4-overexpressing microglial cells kept higher secretion of BDNF. We conclude that the activation of ATF4 can increase BDNF release from microglial cells.
