The Claim

In glucose-deprived A549 lung adenocarcinoma cells, elevated expression of phosphoenolpyruvate carboxykinase 2 (PCK2) is associated with increased glutamine utilization, enhanced glycolysis, and greater cell proliferation, migration, and invasion through activation of the AMPK–CEBPB signaling axis, which upregulates the glutamine transporter SLC38A2.

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 lung cancer cells deprived of glucose, higher levels of the PCK2 enzyme correlate with increased use of glutamine, higher glycolytic activity, and greater cell growth and spread, driven by activation of the AMPK–CEBPB pathway and increased expression of the SLC38A2 glutamine transporter.

See the scientific wording

In glucose-deprived A549 lung adenocarcinoma cells, elevated expression of phosphoenolpyruvate carboxykinase 2 (PCK2) is associated with increased glutamine utilization, enhanced glycolysis, and greater cell proliferation, migration, and invasion through activation of the AMPK–CEBPB signaling axis, which upregulates the glutamine transporter SLC38A2.

Why this might work

When sugar is scarce, cells increase a protein called PCK2, which turns on AMPK, which activates CEBPB, which turns on a glutamine transporter called SLC38A2. More glutamine enters the cell, feeds into energy production, and fuels the creation of molecules needed for rapid growth and spread. This process allows cancer cells to survive and invade even without sugar.

  1. Study: Phosphoenolpyruvate carboxykinase 2 activation of the AMPK–CEBPB axis to enhance glutamine utilization to promote glycolysis and malignant behavior in adenocarcinomas cells under glucose deprivation

    When lung cancer cells don't have enough sugar, they use a protein called PCK2 to turn on a signal that makes them suck up more glutamine, which helps them grow and spread faster. The study proved this exact chain of events happens.
