The Case of the Should-Be-Missing Proteins

INVESTOR TAKEAWAY

Here’s one of those disturbing-but-not-necessarily-surprising reports about the state of the literature. In this case, the preprint linked is the result of a deliberate search for papers that are working with a list of twenty cell lines that have clear genetic deletions and/or mutations.

ORIGINAL PAPER

WHAT WE KNOW

Then a search was done for Western blot experiments in these papers, with particular attention to cases where the blots show the presence of proteins that should not have been present at all. This is not a comprehensive sieving of the literature (it’s a one-man job), but it does illustrate the size of the problem. 230 such examples were found in 221 papers.

WATCH NEXT

Review the primary source, validate the main result, and establish whether any listed-company transmission is direct.

EVIDENCE

What the evidence supports so far

Research signals

Classification pending.

What remains unverified

The full methodology, effect size, and limitations still require analyst review.

Company impact remains unverified until a direct economic transmission is established.
