Retraction to: Cell Death and Disease (2012) 3, e292; doi:10.1038/cddis.2012.32; published online 5 April 2012.
The authors agree to retract the above article in Cell Death and Disease 2012 due to the use of a mismatched image in Figure 1a first shown in the Journal of Biotechnology, 2001, 88: 89–94. An active collaboration between the research groups of the two above articles occurred in the late nineties. Unfortunately this image shared 10 years ago as a far-western blot example was misunderstood to be the actual far-western blot for HIV-1 Nef as a bait and published in Cell Death and Disease 2012 article. The authors stand behind data showing that Nef by binding to EF1A inhibits ER stress-mediated apoptosis in macrophages. They apologize for any inconvenience caused.
