Impact of sleep deprivation on colon cancer: Unraveling the KynA-P4HA2-HIF-1α axis in tumor lipid metabolism and metastasis.
Article in Molecular metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
objectiveThere is growing evidence that sleep deprivation promotes cancer progression. In addition, colon cancer patients often experience sleep deprivation due to factors such as cancer pain and side effects of treatment. The occurrence of liver metastases is an important factor in the mortality of colon cancer patients. However, the relationship between sleep deprivation and liver metastases from colon cancer has not been elucidated.
methodsA sleep deprivation liver metastasis model was constructed to evaluate the effect of sleep deprivation on liver metastasis of colon cancer. Subsequently, mice feces were collected for untargeted metabolomics to screen and identify the key mediator, Kynurenic acid (KynA). Furthermore, HILPDA was screened by transcriptomics, and its potential mechanism was explored through ChIP, co-IP, ubiquitination experiments, phenotyping experiments, etc.
resultsSleep deprivation promotes liver metastases in colon cancer. Functionally, sleep deprivation aggravates lipid accumulation and decreases the production of the microbiota metabolite KynA. In contrast, KynA inhibited colon cancer progression in vitro. In vivo, KynA supplementation reversed the promoting effects of sleep deprivation on liver metastases from colon cancer. Mechanistically, KynA downregulates the expression of P4HA2 to promote the ubiquitination and degradation of HIF-1α, which leads to a decrease in the transcription of HILPDA, and ultimately leads to an increase in lipolysis of colon cancer cells.
conclusionsOur findings reveal that sleep deprivation impairs intracellular lipolysis by KynA, leading to lipid droplets accumulation in colon cancer cells. This process ultimately promotes colon cancer liver metastasis. This suggests a promising strategy for colon cancer treatment.
