Retraction Note to: Apoptosis (2017) 22:86–97 DOI 10.1007/s10495-016-1314-6

The authors have requested to retract their paper which had already been online, entitled: ‘Advanced oxidation protein products induce chondrocyte death through a redox-dependent, poly (ADP-ribose) polymerase-1-mediated pathway’. DOI 10.1007/s10495-016-1314-6. Their paper reported the advanced oxidation protein products (AOPPs) stimulation cause cell death of human chondrocyte of RA patients with PARP-1 over-expression and characterized the apoptosis mechanisms underlying the redox condition. Many of the figure panels in the paper summarize data from multiple experiments. The authors have now detected a number of errors in these panels. The authors believe that the most responsible course of action is to retract our paper. The authors sincerely apologize for their carelessness and poor arrangement of results and apologize to the community.
