This was done on cells in a lab, not in people. It is a very early step.
This was lab work on tissue samples, not a treatment tried in people.
The short version
Scientists looked at pituitary tumors to see if they carry a protein that special scans can spot.
What was studied. Researchers looked at five adult pituitary glands and 28 pituitary tumors. They stained the tissue to see if a protein called integrin avb6 was there.
What they found. The protein showed up in 20 of the 28 tumors. In those tumors, the share of cells with the protein ranged from 20% to 100%. It was also in normal pituitary tissue, and in the lining of small leftover pockets in the gland. The back part of the gland did not have it.
What this means, and what it doesn't
What it could mean: On some scans, the pituitary gland lights up even when it looks normal. This work helps explain why. It also hints that these tumors might one day be found or treated with drugs that seek out this protein.
What it doesn't mean: This does not mean a new scan or treatment is ready for patients. The work was done on tissue samples under a microscope. No one was treated, and no benefit was shown. It is not a cure. The authors say more study is needed. The protein is also in normal pituitary tissue, which could make such scans harder to read.
