PNAS lifts nicotine-dopamine study embargo early after break
Due to an embargo break, PNAS is lifting the embargo early on the following paper:
Article #11-06277: “Protein kinase C epsilon modulates nicotine consumption and dopamine reward signals in the nucleus accumbens,” by Anna M. Lee and Robert O. Messing
The study was originally embargoed until 3 p.m. Eastern on Monday, September 12. Embargo Watch has asked PNAS for more details, and will update with anything we hear.
Here’s the top of the release PNAS sent out earlier:
Nicotine and alcohol addictions are widespread and frequently appear together, but the molecular reasons for their joint appearance remain elusive. Anna M. Lee and Robert O. Messing explored whether protein kinase C epsilon (PKCε)–an enzyme known to influence the mouse behavioral response to ethanol–also determines how rodents respond to nicotine.
Update, 2:30 p.m. Eastern, 9/12/11: PNAS tells us it was some “niche Web sites in the UK” that broke the embargo, and that there won’t be any sanctions:
An embargoed university press release was accessed through a news distributor based in England, http://www.alphagalileo.org/, and was posted before the embargo lift on several niche Web sites in the UK. Sanctions have not been imposed at this time, though all parties have been notified that repeated or intentional embargo breaks will result in stronger penalties.
