The Claim
In differentiated primary human skeletal muscle cells, ERK1/2 activation plays a role in mediating insulin-induced phosphorylation of the Na,K-ATPase alpha-subunit at Thr-Pro motifs, as shown by inhibition experiments and in vitro kinase assays.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When insulin acts on human muscle cells, it turns on a switch (ERK1/2) that helps modify a specific protein (the sodium-potassium pump) at certain spots—this has been seen in lab tests using drugs and purified enzymes.
See the scientific wording
ERK1/2 activation is involved in insulin-induced phosphorylation of the Na,K-ATPase alpha-subunit at Thr-Pro motifs in differentiated primary human skeletal muscle cells, as demonstrated by inhibition and in vitro kinase experiments.
What the research says
1 studyThe study shows that insulin causes a specific protein change in muscle cells by turning on a molecule called ERK1/2, and proves it using targeted experiments that match what the claim describes.
