Hundreds of cancer papers presented incorrect data after p16 protein mixup

- An antibody mix-up involving p16-INK4a (a tumor suppressor) and p16-ARC (an actin cytoskeleton protein) has led to hundreds of papers using the wrong antibody.
- Over 400 research papers, including high-impact studies in Nature, Nature Medicine, and Cancer Cell, incorrectly used p16-ARC antibodies (like ab51243) to target p16-INK4a.
- Only 5% of the identified papers used the p16-ARC antibodies correctly; 95% mistakenly aimed to study p16-INK4a, often producing seemingly valid but likely erroneous results.
- The error persists because p16-ARC antibodies appear as top search results for "p16" on vendor sites like Abcam, and many researchers omit proper validation controls.
- Possible explanations for the false results include data manipulation, selective reporting, or incorrect method documentation, with some cases already retracted for fraud.
