Scientific journal retracts diabetes study

NEW YORK A scientific journal is retracting a research paper published more than eight years ago that reported a gene therapy treatment had led to remission of Type 1 diabetes in rats and mice, the Associated Press reported.

In its Thursday issue, Nature said the lead author of the paper - Hyun-chul Lee of Yonsei University in Seoul, South Korea - and two other authors asked for the retraction because they could not reproduce the experiment's results.

Another author maintains the results are still valid and did not join in the retraction request, the journal said. A fifth author is deceased.

In Type 1 diabetes, the body mistakenly attacks insulin-producing cells. Patients must inject themselves with insulin to survive. The researchers reported eliminating the disease in rodents by slipping into them a man-made gene designed to produce an insulin-like chemical.

The authors wrote at the time that the approach might be useful for humans.
