Role of mammalian target of rapamycin signaling in autophagy and the neurodegenerative process using a senescence accelerated mouse-prone 8 model.

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 mammalian target of rapamycin (mTOR) kinase is an inhibitor of autophagy, which is an intracellular system involved in the degradation of long-lived proteins and organelles in lysosomes. Recent evidence suggests that the steady incline in mTOR function during aging may be associated with the cognitive decline related to aging and may also promote development of Tau pathology. At present, the senescence accelerated mouse prone 8 (SAMP8) is an experimental model that has been proposed for the study of age-related neurodegenerative changes associated with aging. In the present study, mTOR signaling in the hippocampus of SAMP8 newborn mice and in the control-strain SAMR1 mice was investigated. Consequently, hyper phosphorylated Tau (pS199 or pS396) and upregulated mTOR activity were observed in SAMP8 when compared with SAMR1; however, 0.5 µM rapamycin administration significantly reduced the levels of phosphorylated Tau and p70S6K (pT389) in SAMP8 mice. Related to these findings, SAMP8 exhibited an increase in the neuronal loss of hippocampus that was associated with lower levels of anti-apoptotic proteins. These results indicate that mTOR signaling participates in the neurodegenerative process and rapamycin administration may protect neurons of SAMP8 mice and may have a potential role in curing cognitive decline.
