The Claim

The expression of GLUT5 (SLC2A5) is elevated in human colorectal cancer tissues compared to adjacent normal tissue, resulting in increased fructose uptake under low-glucose conditions.

Source: GLUT5-KHK axis-mediated fructose metabolism drives proliferation and chemotherapy resistance of colorectal cancer.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In human colorectal cancer tissues, the GLUT5 protein is present at higher levels than in nearby healthy tissue, leading to greater absorption of fructose when glucose is scarce.

See the scientific wording

The expression of GLUT5 (SLC2A5) is elevated in human colorectal cancer tissues compared to adjacent normal tissue, enabling increased fructose uptake under low-glucose conditions.

Why this might work

When glucose is scarce in colorectal tumors, cancer cells increase GLUT5 protein levels to pull fructose from their surroundings. Fructose enters the cell and binds to ketohexokinase, preventing its breakdown. This allows fructose to be converted into energy and building blocks for cell growth, helping the tumor survive and resist treatment.

  1. Study: GLUT5-KHK axis-mediated fructose metabolism drives proliferation and chemotherapy resistance of colorectal cancer.

    Cancer cells in the colon make more of a protein called GLUT5 than normal cells, which lets them suck up fructose when sugar (glucose) is low — helping them grow and survive. The study shows this happens for real in human tumors.
