The Claim

In differentiated primary human skeletal muscle cells, insulin increases Na,K-ATPase activity and induces the translocation of the enzyme's alpha-subunits to the plasma membrane, a process associated with phosphorylation mediated by the ERK1/2 signaling pathway.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Supports
3score
Challenges
0score

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

Insulin helps move certain proteins to the surface of human muscle cells and boosts their activity, and this seems to involve a specific cellular signaling process.

See the scientific wording

In differentiated primary human skeletal muscle cells, insulin increases Na,K-ATPase activity and promotes translocation of the enzyme's alpha-subunits to the plasma membrane, a process linked to phosphorylation events involving ERK1/2 signaling pathways.

What the research says

1 study

  1. Study: ERK1/2 Mediates Insulin Stimulation of Na,K-ATPase by Phosphorylation of the α-Subunit in Human Skeletal Muscle Cells*

    The study shows that insulin turns on a protein called ERK1/2 in human muscle cells, which helps move and activate a pump (Na,K-ATPase) in the cell membrane, just like the claim says.
