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

Cytochrome P450 (P450) enzymes are involved in the metabolism of carcinogens, as well as drugs, steroids, vitamins, and other classes of chemicals. P450s also oxidize ethanol, in particular P450 2E1. P450 2E1 oxidizes ethanol to acetaldehyde and then to acetic acid, roles also played by alcohol and aldehyde dehydrogenases. The role of P450 2E1 in cancer is complex in that P450 2E1 is also induced by ethanol, P450 2E1 is involved in the bioactivation and detoxication of a number of chemical carcinogens, and ethanol is an inhibitor of P450 2E1. Contrary to some literature, P450 2E1 expression and induction itself does not cause global oxidative stress in vivo, as demonstrated in studies using isoniazid treatment and gene deletion studies with rats and mice. However, a major fraction of P450 2E1 is localized in liver mitochondria instead of the endoplasmic reticulum, and studies with site-directed rat P450 2E1 mutants and natural human P450 2E1 N-terminal variants have shown that P450 2E1 localized in mitochondria is catalytically active and more proficient in producing reactive oxygen species and damage. The role of the mitochondrial oxidative stress in ethanol toxicity is still under investigation, as is the mechanism of altered electron transport to P450s that localize inside mitochondria instead of their typical endoplasmic reticulum environment.
