Description
The transcriptomes of differentiated and undifferentiated E14 (male), Pgk12.1 (female; WT) and Pgk12.1 with a KO of Rlim (RlimKO) were elucidated and examined for differences in X chromosome inactivation. No significant differences between wt and RlimKO with respect to Xist expression and global X-silencing was detected. Results confirm that Rlim is not required for XCI in female ESCs. Overall design: Transciptomes of female WT (Pgk12.1) and female RlimKO ESCs were compared to those of male ESCs (E14). State of XCI in undifferentiated and differentiated ESCs was determined by comparing expression of Xist and expression of X-linked genes female versus male.
