This Expression of Concern relates to J. Cell Sci. (2005) 118, 623-632 (doi:10.1242/jcs.01661).
An issue initially raised by a reader and on PubPeer suggests that there is a duplication of the tubulin blots for samples from 164-JAM-A+/+ and 160-JAM-A FL cells in Fig. 4B of this article.
The journal has been unable to get in touch with the authors of this study and have learnt that the first and last authors have recently retired.
We are therefore publishing this Expression of Concern to make readers aware of this issue and our efforts to resolve it.
