というわけで、Summaryだけチラリ。

-----------------------------------

In female mammalians, the paternal X chromosome (Xp) is selectively inactivated during early development, whereas the maternal X-chromosome (Xm) remains active. It has been proposed that the Xm is imprinted so that it can maintain its active status, although the nature of the imprint is not yet identified. DNA methylation is one of the candidates, since it is required for autosomal imprinting. ---(中略)--- These results underscore the difference between the X-chromosomal and autosomal genomic imprinting.
