RETRACTED: Assembly of Endogenous oskar mRNA Particles for Motor-Dependent Transport in the Drosophila Oocyte

This article has been retracted at the request of the authors. Please see Elsevier Policy on Article Withdrawal: . Reason: In this paper, we used cryoimmuno-electron microscopy and live cell imaging to investigate the sequential assembly of oskar mRNA into an mRNP competent for transport from the Drosophila nurse cells to the oocyte posterior pole. We have recently identified instances in all of the figures where the cryoimmuno-EM data were inappropriately manipulated by the first author. The manipulations do not affect the live cell imaging data. We are in the process of reanalyzing the raw experimental cryoimmuno-EM data, but can already state that the published conclusions are not fully consistent with the raw data. We are therefore retracting the paper. We sincerely apologize for any inconvenience this might have caused.
