Regarding Yu S-M, Chen S-F, Lau Y-T, Yang C-M, and Chen J-C (1996) Mechanism of extracellular ATP-induced proliferation of vascular smooth muscle cells. Mol Pharmacol 50:1000-1009.

A faculty committee at Chang-Gung Medical College concluded that parts of this article contained results identical or nearly identical to those published in Circulation 94:547-554 (1996), but that the results were purportedly obtained with different chemicals (ATP in Molecular Pharmacology and norepinephrine in Circulation). Figs. 3, 5, and 9 (both the original version and corrected version published in the March 1997 issue) were found to have been misrepresented. Based on our conclusion that at least some of the data in this article has been fabricated, we are regrettably unable to verify that the conclusions in this article are correct, and we wish to retract the article. We deeply regret this unfortunate situation, which has potentially misled interested readers of this journal.
