abstract：:Following Northern analysis, GGT mRNA was found predominantly within the caput epididymides and kidney. The size of mRNAs for kidney, caput, corpus, and ductus deferens were 2.2, 2.3, 2.2, and 2.3 kb, respectively, whereas cauda showed a doublet of 2.2 and 2.3 kb. GGT transpeptidation and hydrolytic activity within ep...

abstract：:XIST is an X-linked, non-coding gene responsible for the cis induction of X-chromosome inactivation (XCI). Knockout of the XIST allele on an active X chromosome abolishes erroneous XCI and enhances the in vivo development of cloned mouse embryos by more than 10-fold. This study aimed to investigate whether a similar m...
