From a press release issued by NPG on May 19, 2010:
Nature Publishing Group (NPG) is pleased to announce open access options for seven further journals. Twenty-five journals published by NPG now offer authors an open access option, including all 15 academic journals owned by NPG.
American Journal of Gastroenterology, Bone Marrow Transplantation, Gene Therapy, International Journal of Obesity, Journal of Cerebral Blood Flow and Metabolism, Oncogene, and Leukemia have all recently introduced open access options. Authors publishing in these journals can now choose to make their article open access on payment of an article processing charge (APC).
APCs on these journals vary, depending on the selectivity of the journal, the amount it publishes and associated rejection rate. Full details are available on each journal’s website. Authors who opt to pay the APC will benefit from: a choice of licenses, including one that allows derivative works; immediate and permanent access for all to the final published version of their paper on nature.com and in PubMed Central; the rights to self-archive the final published version of their paper for public access immediately on publication.
Including the American Journal of Gastroenterology and Journal of Cerebral Blood Flow and Metabolism, seven journals published by NPG on behalf of societies offer open access options. Other journals in this portfolio with an open access are: British Journal of Cancer, The EMBO Journal, EMBO reports, European Journal of Human Genetics and Molecular Therapy.
