The Claim
TAS1R3 protein and mRNA levels are reduced by more than 50% in skeletal muscle biopsies from individuals with type 2 diabetes compared to non-diabetic donors.
What the research says
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.
In people with type 2 diabetes, the amount of TAS1R3 protein and its corresponding mRNA in skeletal muscle is more than 50% lower than in people without diabetes.
See the scientific wording
TAS1R3 protein and mRNA levels are reduced by more than 50% in skeletal muscle biopsies from individuals with type 2 diabetes compared to non-diabetic donors, suggesting a potential link between diminished TAS1R3 expression and impaired glucose metabolism in human muscle tissue.
In muscle cells, a protein called TAS1R3 detects nutrients and turns on a chain reaction that reshapes the internal skeleton of the cell. This reshaping allows sugar transporters to move to the cell surface, where they pull glucose from the blood into the muscle. When TAS1R3 is missing, this chain reaction stops, the skeleton stays rigid, the sugar transporters cannot reach the surface, and glucose stays in the blood.
What the research says
1 studyStudy: TAS1R3 Regulates GTPase Signaling in Human Skeletal Muscle Cells for Glucose Uptake
People with type 2 diabetes have much less of a protein called TAS1R3 in their muscles than people without diabetes, and when scientists reduced this protein in lab-grown muscle cells, the cells took up less glucose — suggesting this protein helps muscles absorb sugar from the blood.
