TIF1
functions as a coactivator for C/EBP
and is required for
induced differentiation in the myelomonocytic cell line U937
John W. Rooney and Kathryn L. Calame
"Following publication of this paper, I was informed by a
colleague at another institution that experiments performed by Dr. Rooney, which are illustrated in Figure 1, could not be reproduced. Researchers in my laboratory performed the experiments again and found
that TIF1
mRNA is not induced upon treatment of U937 cells with PMA
or upon treatment of HL-60 cells with PMA or DMSO. TIF1
mRNA is
expressed at similar levels before and after treatment in both lines.
Given the central importance of this observation, I wish to retract the
paper and Dr. Rooney agrees to this retraction."
