The Claim
In L6 rat skeletal muscle cells under insulin stimulation, knockdown of KLF3 increases phosphorylation of AKT at Ser473 and Thr308 by 40–50% and enhances translocation of GLUT4 to the plasma membrane, indicating that KLF3 suppresses insulin signaling at the level of AKT activation and GLUT4 trafficking.
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 rat muscle cells exposed to insulin, reducing KLF3 protein levels increases AKT phosphorylation at two specific sites and moves more GLUT4 to the cell membrane.
See the scientific wording
In L6 rat skeletal muscle cells, KLF3 knockdown increases phosphorylation of AKT at Ser473 and Thr308 by 40–50% under insulin stimulation and enhances translocation of GLUT4 to the plasma membrane, indicating KLF3 suppresses insulin signaling at the level of AKT activation and GLUT4 trafficking.
When KLF3 is reduced, muscle cells increase the production of proteins that help insulin signal properly and decrease proteins that block insulin. This allows AKT to become more active, which then triggers GLUT4 transporters to move to the cell surface, letting more sugar enter the cell.
What the research says
1 studyStudy: KLF3 impacts insulin sensitivity and glucose uptake in skeletal muscle.
When scientists reduced a protein called KLF3 in rat muscle cells, the cells responded better to insulin — they let in more sugar because key signals (AKT and GLUT4) worked stronger. This means KLF3 normally holds back sugar uptake, and removing it helps.
