摘要：
The expression of mouse Zfx, Rps4, Ube1x, and Xist was evaluated in hamster-mouse somatic cell hybrids containing either an active or an inactive mouse X chromosome using polymerase chain reaction of reverse transcribed RNA (RT-PCR). The results showed that Zfx, Rps4, and Ube1x are expressed exclusively from the active mouse X, while Xist is expressed exclusively from the inactive X These findings confirm the pattern of X inactivation for these mouse genes reported previously based on expression in somatic tissues of F1 females from interspecific crosses. These results demonstrate the existence of differences between human and mouse X inactivation, as the corresponding human genes, ZFX, RPS4X, and UBE1 escape X inactivation.
