A study published in Nature finds that hepatocytes promote liver metastasis of pancreatic cancer by providing serine.

What it means

This Nature paper reports that hepatocytes (liver cells) supply the amino acid serine to pancreatic cancer cells that have metastasized to the liver, thereby promoting their growth. The study identifies a metabolic dependency in liver metastases of pancreatic ductal adenocarcinoma (PDAC) that lack the ability to synthesize serine themselves, suggesting a potential therapeutic vulnerability.

Accuracy & sourcesGrounded

The claim is based on a peer-reviewed study published in Nature, a top-tier scientific journal, making it highly credible. The primary source is the actual research paper (doi:10.1038/s41586-026-11051-z), and the reporting sits directly on that source.

How new

The paper was published on September 23, 2026, making this genuinely new research.
