There are potential issues in Fig 4 in Biol. Open (2017) 6, 489-495 (doi:10.1242/bio.024133).

In Fig 4B, it appears there is background duplication in the NC and 80μM Tan IIA+ox-LDL panels, and also in the ox-LDL and 40μM Tan IIA+ox-LDL panels.

We have made multiple attempts to contact all authors to request original data for the affected figures but have not received a response. Therefore, the journal is publishing this note to alert readers to our concerns.
