Mannose Inhibits the Pentose Phosphate Pathway in Colorectal Cancer and Enhances Sensitivity to 5-Fluorouracil Therapy.
Article in Cancers, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Colorectal cancer (CRC) is one of the leading cancers and causes of death in patients. 5-fluorouracil (5-FU) is the therapy of choice for CRC, but it exhibits high toxicity and drug resistance. Tumorigenesis is characterized by a deregulated metabolism, which promotes cancer cell growth and survival. The pentose phosphate pathway (PPP) is required for the synthesis of ribonucleotides and the regulation of reactive oxygen species and is upregulated in CRC. Mannose was recently reported to halt tumor growth and impair the PPP. Mannose inhibitory effects on tumor growth are inversely related to the levels of phosphomannose isomerase (PMI). An in silico analysis showed low PMI levels in human CRC tissues. We, therefore, investigated the effect of mannose alone or in combination with 5-FU in human CRC cell lines with different p53 and 5-FU resistance statuses. Mannose resulted in a dose-dependent inhibition of cell growth and synergized with 5-FU treatment in all tested cancer cell lines. Mannose alone or in combination with 5-FU reduced the total dehydrogenase activity of key PPP enzymes, enhanced oxidative stress, and induced DNA damage in CRC cells. Importantly, single mannose or combination treatments with 5-FU were well tolerated and reduced tumor volumes in a mouse xenograft model. In summary, mannose alone or in combination with 5-FU may represent a novel therapeutic strategy in CRC.
