Cryptic DNA sequences encode a temperature sensor to regulate mitochondrial suicide during neuronal differentiation.

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
Accumulating evidence suggests that transient mitochondrial hyperactivity shapes the early stage of neuronal differentiation although mechanistic details remain largely unknown. Here, we report a mitochondrial suicide program which is activated in response to thermal flux to terminate this early stage of mitochondrial hyperactivity. A conserved stem loop at the mitochondrial origin of replication of the light strand operates as a thermal sensor, denaturing upon enhanced thermal flux and repressing the replication of the parental heavy strand of mitochondrial DNA. This triggers a quasi-replication of mitochondrial DNA characterised by replication of only the parental light strand. The non-replicated single-stranded heavy strand is then released and operates as a natural antisense DNA which sequesters complementary mRNAs encoded by the heavy strand. Subsequent degradation of the bound mRNAs by RNase H1 completes the cycle by triggering mitochondrial transcriptional decline and ultimately mitochondrial death.
