TFEB-dependent autophagy-lysosomal pathway is required for NRF2-driven antioxidative action in obstructive sleep apnea-induced neuronal injury.

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
Nearly one billion individuals worldwide suffer from obstructive sleep apnea (OSA) and are potentially impacted by related neurodegeneration. TFEB is considered a master regulator of autophagy and lysosomal biogenesis, but little is known about its role in neuronal oxidative stress and resultant injury induced by OSA. This study aimed to investigate these issues. Here, we demonstrated that neuronal TFEB induction is repressed in OSA mouse models. Activation of a TFEB-dependent autophagy-lysosomal pathway (ALP) reduces hippocampal neuronal cell death and mitigates OSA-related cognitive impairment. Neuronal NRF2 induction was also found to be defective in OSA mouse models. A series of staining assays for HO1, SOD3, ROS, GSH, 8-OHdG, MDA and PI revealed that enhancement of NRF2 expression restores neuronal redox balance and protects hippocampal neurons. We then identified a novel interplay between TFEB-dependent ALP and NRF2-mediated relief of oxidative stress. Inhibition of NRF2 hinders TFEB expression and lysosomal biogenesis. Conversely, knockdown of TFEB or blocking autophagy dampens the antioxidative effect of NRF2. Our findings highlight the unexpected and crucial role of TFEB-dependent ALP as a downstream event of NRF2 in NRF2-promoted redox balance. This study provides novel insights into the mechanism behind NRF2-driven antioxidative action and the regulation of TFEB-dependent ALP.
