The Claim

In human lung adenocarcinoma tissues, PCK2 and SLC38A2 expression levels are significantly higher than in adjacent non-tumor tissues, and the expression levels of PCK2 and SLC38A2 are positively correlated.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

In human lung cancer tissues, the levels of two proteins, PCK2 and SLC38A2, are higher than in nearby healthy lung tissue, and the amounts of these two proteins increase together.

See the scientific wording

In human lung adenocarcinoma tissues, PCK2 and SLC38A2 expression levels are significantly higher than in adjacent non-tumor tissues, and their expression levels are positively correlated, suggesting a clinical association between this metabolic pathway and tumor presence.

Why this might work

When glucose is scarce, cancer cells in the lung produce more PCK2, which turns on AMPK, which then activates CEBPB. CEBPB turns up the production of SLC38A2, a protein that pulls glutamine into the cell. The glutamine feeds into energy production pathways, allowing the cancer cells to keep making energy and grow even without glucose.

    The study found that two proteins, PCK2 and SLC38A2, are more common in lung cancer tumors than in healthy lung tissue, and that when one is high, the other tends to be high too — just like the claim says. It also shows how one protein helps turn on the other, explaining why they work together in cancer.
