Inhibition of myogenesis by MyoR

Expression vector	No. of MHC-positive cells per well
None	0
MyoR	0
MyoR + MEF2C	0
MyoD	>50
MyoD + MyoR	0–2
Myogenin	>20
Myogenin + MyoR	0

10T½ cells were transiently transfected with 1 μg of MyoD or myogenin expression vectors in the presence or absence of 1 μg of MyoR expression vector. The number of MHC-positive cells per well is indicated. The few MHC-positive cells observed in transfections with MyoD + MyoR did not express MyoR, as detected with anti-FLAG-antibody.
