This article refers to:

Brk/Protein Tyrosine Kinase 6 Phosphorylates p27KIP1, Regulating the Activity of Cyclin D–Cyclin-Dependent Kinase 4

The American Society for Microbiology (ASM) and Molecular and Cellular Biology (MCB) are issuing this Expression of Concern regarding the following publication:

Patel P, Asbach B, Shteyn E, Gomez C, Coltoff A, Bhuyan S, Tyner AL, Wagner R, Blain SW. 2015. Brk/protein tyrosine kinase 6 phosphorylates p27^KIP1, regulating the activity of cyclin D–cyclin-dependent kinase 4. Mol Cell Biol 35(9):1506–1522. https://doi.org/10.1128/MCB.01206-14.

Molecular and Cellular Biology was notified that the above-mentioned paper was investigated by the SUNY Downstate Health Sciences University and that potential image duplications were found in Fig. 2C, H, and I.

This Expression of Concern is issued pending the outcome of ongoing litigation between SUNY Downstate Health Sciences University and the corresponding author of the paper, Stacy Blain, in the United States District Court of the Eastern District of New York.
