Sentence examples for maternal imprint is from inspiring English sources

A known differentially methylated region (DMR) within the H19 gene locus, which is demethylated in oocytes after establishment of the maternal imprint, is hypomethylated in PGC-like cells compared to undifferentiated skin-derived stem cells, suggesting that the putative germ cell population undergoes imprint erasure.

These results demonstrate that the maintenance of the maternal imprint is highly sensitive to dCTCF dosage.

Contrary to the prevailing model, this maternal imprint is erased in both the embryonic and extraembryonic lineages.

In Drosophila, the primary effect of the maternal imprint is to inhibit the spread of heterochromatin-induced silencing (that is, silencing that turns euchromatin into a more compact state that limits the access of transcription factors to the genes).

This maternal imprint is erased and re-established in female gametes prior to ovulation at the 1N stage, which occurs much later in comparison to the establishment of the paternal imprint at the 2N stage in spermatogenesis.

In a reverse transgenic mouse line, in which the maternal mouse PWS-IC has been replaced by the human PWS-IC (PWS-ICHs/+) (37), the maternal imprint is lost and therefore the normally silent maternal allele expresses Snrpn, snoRNAs and Ube3a-AS.

No evidence for imprinting has been found for Xenopus but this hypothesis would require that imprinting may occur in Xenopus and that maternal imprinting is the controller of the expression pattern in whole frog testes [69].

This distinction suggests that the paternal imprint is much easier to reverse than a maternal imprint.

For example, an overgrown placenta (hydatidiform mole) results when maternal imprints are missing.

Likely maternal imprinting was observed at 2q23, and possible maternal imprinting at 3q28.

At this QTL, maternal imprinting was identified indicating that only the paternal allele is expressed.
