Sentence examples for imprint is established from inspiring English sources

For H19, the imprint is established during the adult spermatogonial stage or at least before the spermatocytes enter meiosis I, and is maintained thereafter (Kerjean et al., 2000), resembling the reprogramming in the mouse (Ueda et al., 2000).

This could suggest a difference in the mechanism or developmental stage during which the two types of somatic imprint are established.

Imprinting is established largely due to epigenetic differences arriving in the zygote from sperm and egg haploid genomes.

Understanding the molecular mechanisms by which imprinting is established in all mammals is critical to furthering knowledge about imprint gene regulation in humans.

Methylation at DMR1 has been shown to occur late in development in a tissue-specific manner after imprinting is established and is thought to be a consequence of Airn expression [ 17].

Imprinting is established early in development, and some are maintained throughout the life course in multiple tissues, providing a plausible mechanism linking known early life factors to cancer risk.

These results suggest that methylation imprints are established via dynamic changes during early embryonic development in porcine embryos.

The aim of this study was to demonstrate how differential methylation imprints are established during porcine preimplantation embryo development.

It has been demonstrated that epigenetic imprints are established during gametogenesis in a parent-specific manner [41] [43], and that the DNA methylation status of imprinted genes is erased and reset during PGC development [44], [45].

The genomic imprints are established during the development of germ cells into sperms and eggs.

The imprints are established already during gametogenesis (Bourc'his et al. 2001; Delaval and Feil 2004).
