    ..We conclude that, although SCNT embryos can reactivate, count, and inactivate X chromosomes, they are not able to regulate XCI consistently. These results illustrate the heterogeneity of epigenetic changes found in cloned embryos. ..

    ..This study clearly demonstrates the importance of the location of CpG site methylation for HCC specificity and how liver-specific DNA methylation should be considered when an epigenetic DNA marker is studied for detection of HCC. ..

    ..No indication of hypermethylation was found. These results suggest that hRad51 is not a tumor suppressor because it is either an essential gene, redundant gene and/or independent of the BRCA1/BRCA2 tumor suppressor pathway(s). ..
