1 · What the graph read from it

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.

2 · The registry

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

Warburg proposed that cancer originates from irreversible injury to mitochondrial oxidative phosphorylation (mtOXPHOS), which leads to an increase rate of aerobic glycolysis in most cancers. However, despite several decades of research related to Warburg effect, very little is known about the underlying genetic cause(s) of mtOXPHOS impairment in cancers. Proteins that participate in mtOXPHOS are encoded by both mitochondrial DNA (mtDNA) as well as nuclear DNA. This review describes mutations in mtDNA and reduced mtDNA copy number, which contribute to OXPHOS defects in cancer cells. Maternally inherited mtDNA renders susceptibility to cancer, and mutation in the nuclear encoded genes causes defects in mtOXPHOS system. Mitochondria damage checkpoint (mitocheckpoint) induces epigenomic changes in the nucleus, which can reverse injury to OXPHOS. However, irreversible injury to OXPHOS can lead to persistent mitochondrial dysfunction inducing genetic instability in the nuclear genome. Together, we propose that "mitocheckpoint" led epigenomic and genomic changes must play a key role in reversible and irreversible injury to OXPHOS described by Warburg. These epigenetic and genetic changes underlie the Warburg phenotype, which contributes to the development of cancer.
