GENETICS PNAS is publishing an Editorial Expression of Concern regarding the following article: “Parkin, a gene implicated in autosomal recessive juvenile parkinsonism, is a candidate tumor suppressor gene on chromosome 6q25–q27,” by Rossano Cesari, Eric S. Martin, George A. Calin, Francesca Pentimalli, Roberta Bichi, Holly McAdams, Francesco Trapasso, Alessandra Drusco, Masayoshi Shimizu, Valeria Masciullo, Giuseppina d'Andrilli, Giovanni Scambia, Maria Cristina Picchio, Hansjuerg Alder, Andrew K. Godwin, and Carlo M. Croce, which appeared in issue 10, May 13, 2003, of Proc Natl Acad Sci USA (100:5956–5961; first published April 28, 2003; 10.1073/pnas.0931262100).
The editors wish to note that Fig. 2a and 2b, β-actin panel, appears to have duplicated bands. The authors note that “because this issue was first raised more than 10 years after publication, the original data are not available to confirm whether an error was made in the figure construction.” However, the authors state that any error in figure construction does not affect their scientific conclusions.
