Lab's results aren't reliable
U.S. agency faults ex-UNC scientist

A former UNC-Chapel Hill molecular biologist altered research materials and circulated faked lab results, says a federal agency that investigates research fraud.
The Office of Research Integrity released a ruling Thursday that molecular biologist Steven "Tony" Leadon falsified information in four grant applications, eight scientific publications and an unnamed manuscript.

Leadon, who resigned from UNC-CH in 2003, insists that he is not a cheat. An error in an experimental protocol, not scientific misconduct, produced problems in his lab, he said Thursday in a written statement.

Leadon has agreed not to apply for federal research money for five years and to expand the number of scientific journals where he must retract his results.

He said he did that only because he doesn't have the means to fight the government. "Like most hard-working people with families, I cannot afford the huge legal costs to fight with a government agency about this," said the former professor, who landed more than $2.5 million in government funding while at UNC-CH.

After examining Leadon's laboratory records and questioning his staff, a UNC-CH faculty committee in 2003 concluded that the scientist falsified research results. The inquiry was convened after a Ph.D. student working in Leadon's lab reported that she suspected fraud.

The Office of Research Integrity investigated allegations against Leadon after university officials alerted the agency of their findings.

But UNC-CH research Vice Chancellor Tony Waldrop said campus officials were not celebrating news that the federal government has backed them up. "One takes no satisfaction in that," he said. "The satisfaction comes from knowing that we can handle such things appropriately."

Honesty about lab results is a core value in science. It is vital when those results are part of a research project involving several scientists.

Leadon participated in many collaborative projects, contributing a test that he said could measure the rate at which DNA repairs itself in cells. Faulty repair machinery is a suspected cause of some diseases, including cancers.

Leadon was loudly criticized by former collaborators after UNC-CH disclosed its conclusions and alerted several research journals that data produced in Leadon's lab may not be reliable.

Beginning in 2003, prominent journals such as Science retracted articles that Leadon co-wrote. He has agreed to retract information submitted to three more publications, including the Proceedings of the National Academy of Sciences.

Letters from Leadon requesting the retractions, published Thursday in the Federal Register, all say the same thing: Data from Leadon's lab "cannot be relied upon."
